Making Dioramas of Women Scientists Help Elementary Students Recognize Their Contributions

The STEM movement encourages girls to consider careers in science; however, for success, common misconceptions and biases need to be dispelled, while females’ spatial thinking skills are developed. All students, both girls and boys, need exposure to the accomplishments of women scientists to appreciate their contributions and to envision females as successful scientists. This oneweek study conducted during a summer day camp examined upper elementary student (n = 15; 7 females, 8 males) attitudes toward science, women in science, and the possibility of a science career before and after participation in learning about diverse accomplished women scientists and making a diorama showcasing the professional work and caring actions of one of the scientists. The efficacy of this project for upper elementary students, conducted during a summer day camp, is supported by pretest-posttest data and attitude surveys. The five-day class showed positive changes in student plans for a career in science and improved attitudes toward the importance of females becoming scientists. Directions for constructing dioramas, examples of student-made work, and creative scenes made with given craft items are provided.


The Women Scientists Diorama Project
This model-construction and science learning activity project focused on changing boys' and girls' ideas about women's contributions to science by exploring the lives and work of eight notable women scientists through making a three-dimensional diorama. The investigators asked, "How will making a diorama of a woman scientist's life and work, and hearing about the lives of other female scientists through electronic slide presentations affect elementary student attitudes toward women in science and a science career in general?" The study took place during a week-long summer day camp in which 15 students entering grades 4, 5, and 6 attended the women scientist diorama class for approximately 45 minutes each day.
The diorama-creation activities were designed to maximize positive impact on the elementary student participants in the following ways: • Eight female scientists were highlighted to focus attention on women's proficiency and contributions to science. Contemporary or near contemporary women scientists were chosen, rather than historic women scientists such as Marie Curie, so that students would become familiar with modern role models. Two previous studies (Mead & Métraux, 1957;The Research Business, 1994) indicated that most high school students were familiar only with famous men of science like Einstein, Bell, and Newton. The earlier study (Mead & Métraux, 1957) recommended that science teachers focus more on tales of what scientists do in their daily work. The cultural significance of women scientists' work was highlighted, as Munro and Elsom (2000) found that science teachers tend to emphasize the instrumental value of scientists' work to the advancement of science, causing students to surmise that science is only of value to scientists with little impact on everyday life. • The diorama work presented many spatial problems such as: how to make a pop-out scene, how both the interior and exterior of a building could be portrayed in a diorama that opened like a book, arrangement of images, and making of miniature furnishings. This three-dimensional work supported development of spatial skills important to success in STEM fields (Root-Bernstein & Root-Bernstein, 2013). • Women scientists were chosen to present a racially diverse group of scientists working in different areas of science with a variety of scientific, personal, and social challenges. The number of minority students pursuing STEM careers is small, partly because these students have less access to advanced science and mathematics coursework in high school (Perna et al., 2009). Another reason minority students do not pursue STEM fields is the lack of a network of support leading to self-efficacy in science (Chemers, Zurbriggen, Syed, Goza, & Bearman, 2011). Because many minorities are not aware of minority role models in science (Johnson & Watson, 2005), we chose a diverse group of eight women scientists. Mary Leakey and Dorothy Crowfoot Hodgkin were White British women, Barbara McClintock was a White American; Lisa Perez Jackson and Patricia Bath are African Americans; Tolani Francisco and Joan Esnayra are Native Americans; Ellen Ochoa is a Hispanic American. • The electronic slide show presentations designed by the teachers told about many aspects of each scientist and her work, including ways she was a caring person to counteract the stereotype that successful women in science are cold and uncaring (Heilman et al., 2004).

Standards Addressed by the Women Scientists Diorama Project
Many crosscutting concepts from the Next Generation Science Standards (Achieve Inc., 2013) were addressed by the women scientist diorama project. Table 1 presents these and describes how information provided to students about the women scientists supported the standards. The Benchmarks for Science Literacy (American Association for the Advancement of Science, 1993), in discussing the "Scientific Enterprise, state "By the end of the 5 th grade, students should know that science is an adventure that people everywhere can take part in, as they have for many centuries" (p. 16), and, "By the end of 8 th grade, students should know that until recently, women and racial minorities, because of restrictions on their education and employment opportunities, were essentially left out of much of the formal work of the science establishment; the remarkable few who overcame those obstacles were even then likely to have their work disregarded by the science establishment" (p. 17).
The state in which this study took place, Iowa, has education standards for all grade levels (Iowa Department of Education, 2013). In the area of 21 st Century Skills, at the grade 3-5 level, the Iowa Core states: "Students will choose a career area that interests them, and produce a list of skills, habits, and duties that assure success in that career area." Learning about the lives of women scientists will enlighten students as to what they actually do in their jobs and the required skills and dispositions necessary for being scientists.

Participants
This lesson sequence was conducted with a group of 15 elementary students (7 female, 8 male; 11 White, 2 Black, 2 Hispanic; 5 entering fourth grade, 6 entering fifth grade, and 4 entering sixth grade) during a daily 45-minute class at a weeklong summer day camp. This project was approved by the Human Subjects Committee of the overseeing university and the day camp directors. All participants and their parents provided written consent for data and photographs to be used in the study. Lisa Perez Jackson observed the inequities of clean air and water for people in impoverished communities; therefore, she worked to develop environmental protection agency regulations. Scientific knowledge assumes an order and consistency in natural systems Science assumes consistent patterns in natural systems.
All of the women scientists examined patterns in some way to solve the problems they encountered. For example, crystallographers study X-ray diffraction patterns to determine arrangement of atoms.

Patterns
Similarities and differences in patterns can be used to sort and classify natural phenomena.
Dorothy Crowfoot Hodgkin examined X-ray diffraction patterns to determine the crystal structure of vitamin B-12 and over 100 other compounds.
Similarities and differences in patterns can be used to sort and classify designed products.
Mary Leakey developed a classification system for the stone tools she excavated.
Systems and system models A system can be described in terms of its components and their interactions.
Veterinarian Tolani Francisco worked within the natural interactive system of cattle and bison to determine the transmission of infectious diseases.

Cause and effect
Cause and effect relationships are routinely identified, tested, and used to explain change.
Barbara McClintock conducted genetic experiments with corn, observing the colors of corn kernels to determine her Nobel Prize-winning model of jumping genes.
Scale, proportion, and quantity Natural objects exist from the very small to the immensely large.
Many of the scientists used microscopes (micro scale) or X-ray diffraction (nano scale) in their work; others explored large animals, industrial complexes and outer space (immense scale). Energy and matter Energy can be transferred in various ways between objects.
Lisa Perez Jackson has led the Apple Corporation to develop renewable energy sources for their facilities.

Study Design and Setting
The study took place at a one-week summer music day camp held on the campus of a university and sponsored by the music department of the university. The theme of the music camp was "Full STEAM Ahead," meaning STEM (Science, Technology, Engineering, and Mathematics) education with integrated arts activities (the "A" in STEAM). Over a hundred students attended the K-12 camp. Each student chose an elective course for early morning that was somehow related to the camp's theme. The dioramas of women scientists' course was one of those electives and fit well with the theme because of the focus on learning about scientists through the artwork of a three-dimensional diorama.
The study had a simple pretest-posttest experimental design with all students participating in the lesson activities. Students attended an approximately 45-minute lesson each of the five days of the camp and participated in music-related activities of the day camp the rest of the week. They responded to a pretest on the first day, an attitude survey on Day 2 and Day 4, and a posttest with two additional insight questions on the last day. The outline of the daily lessons is shown in Table 2.

Study Instrumentation
A short pretest-posttest attitude survey of ten items to which students responded by circling "really disagree," Cutting. Students receive about 5 pages of color images for their chosen or assigned scientist and cut them out. 20 minutes Scientist Information. While cutting out images, students listen to two more presentations about scientists: Ellen Ochoa (shuttle astronaut) and Patricia Bath (ophthalmologist).
Day 2 survey administered. 5 minutes 3 Diorama construction. Students glue the front of the face image to cardboard, cut it out again, and then glue the bottom inch of it to the upper front of the box so that the scientist's head stands upright above the box. They then glue the matching back side to the back of the face so that the bottom inch of it is glued inside the box front panel.

minutes
Scientist information. Students listen to two slide show presentations of scientists: Dorothy Crowfoot Hodgkin (chemist and crystallographer) and Tolani Francisco (large animal veterinarian). 15 minutes Diorama Construction. Students work to glue images to the front of the box to decorate the building and to label the box with the scientist's name. Then they begin working on the inside of the building and the opposite scene of the scientist working. 20 minutes 4 Scientist vocabulary game: Students play a new game in which each student is given a scientific career term such as "environmentalist" or "crystallographer" and they must find the classmate with the corresponding definition of the scientist term.

minutes
Students continue decorating the sides of their dioramas with information and images. 15 minutes Students listen to the final two slide show presentations about women scientists: Joan Esnayra (Geneticist) and Lisa Perez Jackson (Environmentalist). Each student receives an identical set of ten craft items from which to construct a scene related to his or her scientist, using all of the materials. They first generate several ideas related to the scientist, then choose one and begin to construct it. The scene is glued to the back of the box.  "kind of disagree," "neutral," "kind of agree," or "really agree" was developed to measure student attitudes during the project. These items were scored from "1" for "really disagree" to "5" for "really agree." The first three items were taken from a large scale market research survey conducted in the United Kingdom for the Institute of Electrical Engineers (The Research Business, 1994): "Science is interesting," "Science is useful for jobs," and "Science is easy." The fourth item measured students' personal ideas about a science career: "I plan to have a career in science." The fifth item addressed attitude toward science's cultural usefulness: "The work of scientists improves our lives." The final five items were created to measure important concepts related to women in science. These items were: "It is important for women to become scientists," "Females do as well as males in science," "Females have made important science findings," "Women scientists can help others through their science careers," and "Women in science can make science more caring." Both pretest and posttest requested the participants to list historic or living women scientists and the areas in which they worked. The posttest contained two additional open-ended questions: "What did you learn about women in science that surprised you?" and "What new ideas or feelings do you have about science now?"

Materials and Equipment for the Dioramas of Women Scientists
The following list of materials and equipment was used to create the dioramas: an empty cardboard food product box for each student approximately 7 × 7 × 1.5 inches (about 18 × 18 × 4 centimeters) in dimension or larger; a smaller empty cardboard box, approximately 4 × 6 × 1.5 inches (about 10 × 15 × 4 centimeters) for each student (attached to front of larger box as a building); white copy paper for covering the boxes to make the papiermâché base (recycled paper printed on one side may be used; place printed side down); scissors; white craft glue (Aleene's Original Tacky Glue is thick and effective, but any brand will work); canvas drop cloths or paper to protect table tops from glue (it is water-soluble, but takes effort to scrub off) and acrylic paint; paint brushes; white acrylic gesso (provides an excellent surface for painting and stiffens the box); acrylic paints of many colors (these non-toxic paints rub off skin, but are permanent on clothing once dry; tempera paints are not recommended-glue makes the paints wet again when the paper images are applied); paint cover-ups for students (the teachers provided large t-shirts that students wore to protect clothing); images and text explanations or labels printed in color on cardstock (the teachers made a PDF file of sized images with text and printed them on cardstock at a copy shop; soluble ink-jet images are not recommended as drops of glue make the ink run); small, cube-shaped pieces of stiff sponge-like foam packing material or Styrofoam for making the pop-out parts of a photographic scene of the scientist working; various small artifacts related to the chosen scientists' work to be attached to the box (e.g., stone tools, corn kernels, crystals, rocks, fossils, small animal figures, toy doctor tools); one identical set of ten items for each student for the creative activity glued to the back of the diorama.

Procedures for Making the Dioramas
The procedure for making the diorama bases is shown in Figure 1. The four teachers (a professor and three doctoral students majoring in curriculum and instruction) prepared the diorama bases, example dioramas, and pages of images before the five-day class began so that students would be able to complete the dioramas in the given time. The professor has made other diorama projects with elementary students and they were able to prepare the diorama bases. Readers should consider having upper elementary students make their own diorama bases (a one to two-hour task) if time permits.
The final creative activity involved making a scene on the back panel of the diorama related to the scientist's life or work by using all ten pieces of an identical set of given items. The items we used are shown in Figure 2. The set consisted of 1) a red speckled cardboard frozen food tray, 2) a yellow fuzzy chenille stick, 3) a white cardboard piece of packaging material, 4) a spherical gold pompon, 5) a wooden Popsicle stick, 6) a six-inch piece of pink grosgrain ribbon, 7) a 3 × 2 inch (about 8 × 5 centimeter) piece of green glitter sheet foam, 8) a small yellow envelope, 9) a strand of five plastic shamrocks molded onto a string cut from a necklace, and 10) a small plastic branch with three fabric leaves.

Student-Made Dioramas
Students were thoroughly engaged in the work of making their dioramas. Figure 3 illustrates students strongly Use glue-coated (on one side) torn pieces of white copy paper in a manner similar to tape to attach the smaller box to the front of the larger box. Use the glue-coated paper to "tape" all around the small box, securing it to the front of the box; (f) Use glue-coated torn paper pieces to "tape" the smaller box to the front panel from the inside. The glue-covered pieces should extend from the back of the front panel to the inside of the smaller box. Let dry a few minutes, pressing the paper so that it dries correctly; (g) Cover the entire inside of the large and small boxes with torn pieces of paper covered with glue on one side. Fold the white glue-covered pieces over the edges of the sides of the box and overlap them somewhat; (h) Cover the entire outside of the two boxes with torn, glue-coated pieces of paper. The paper should be folded over the edges of the box to form a continuous papier-mâché surface. Press on the paper and flatten or gently shape the box as it dries so that it is fairly flat with right angles. After the glue dries, coat the box on all sides with white gesso acrylic paint. This is a thick undercoat that stiffens the box and forms an effective surface for acrylic paints. engaged in their work. Figures 4-9 present examples of the student-made dioramas. The first step during class of painting the boxes was exciting for most of the students. Many painted parts of the box different colors; some students added designs. When deciding where to place the images and information, some students relied heavily on the teacher's example diorama, but others wanted to make their dioramas unique. All students had to make adjustments because of the varying dimensions of the individual boxes. This proved beneficial because it forced students to be creative in their placement of images and text.    Figure 9 show the three-dimensional pop-out scenes of the woman scientist working. After gluing images and information on the box front and narrow sides, students began the three-dimensional scenes of the box interiors. Students expressed enjoyment as they created this spatial effect within their dioramas. Many worked tirelessly to place each piece precisely, giving the best effect. This work was intense for many students, and some had difficulty leaving the project at the end of the class period. When students returned the next day, they immediately started work on the projects, showing their investment in the project.

Pretest-Posttest Results Concerning Attitude Statements
Cronbach's alpha, a coefficient of internal consistency of items on a test or survey, was used to estimate the     reliability of the attitude survey, which contained ten questions. Cronbach's alpha (which varies from zero to one) was 0.81 for the women scientist attitude survey used in this study. In interpreting this result, one should consider that, in general, the higher the number, the greater the internal consistency: a Cronbach alpha score greater than 0.70 is good and above 0.90 is excellent; therefore the Cronbach alpha score for the survey was certainly in the acceptable range (Cronbach, 1970). Table 3 shows that students tended to agree (ratings of 3.5 to 4.5) or strongly agree (ratings > 4.5) with most of the statements on the pretest. The two exceptions were "I plan to have a career in science" and "It is important for women to become scientists," both of which fell into the neutral rating zone (2.5 -3.5). Student attitudes toward these two statements in particular evidenced large positive effect sizes as a result of the class. Exploring the interesting personal stories of diverse women scientists through viewing electronic slide presentations and making dioramas seems to have positively influenced student attitudes.
On the posttest, students expressed greater agreement (mean scores > 3.5) with all of the statements except "Science is easy" and "Females do as well as males in science." The lessening of agreement with these statements may be because the struggles that many women scientists underwent to be successful were discussed in the class. For example, Mary Leakey lived in a tent in the African wilderness, spending day after day scraping the rock layers to uncover fossils, work that required a lot of self-motivation and patience. Barbara McClintock's theory of gene transposition was not accepted as applying to other organisms for many years, resulting in scientists ignoring or belittling her work. Additionally, she feared that she would not be promoted at the University of Missouri because she was female and had to find another research position. Joan Esnayra experienced a childhood of substance, physical, and sexual abuse. She struggled with mental illness stemming from these circumstances but was able to innovatively help others through service animals because she understood their positive psychological effects. She eventually realized her dream of being a scientist, working for the National Academies of Science. Patricia Bath had to overcome prejudices against women and African Americans as she advanced in her ophthalmology career, becoming an advocate for medically underserved populations. These stories of the hardships of women scientists made them more aware of the challenges women scientists may face.
Another aspect emphasized by the teachers of this class was the caring attitude of many women scientists. Previous research by Pauline Lightbody has shown that female students may not picture themselves as scientists because they don't perceive science as a feminine career focused on helping others (Lightbody & Durndell, 1996;. Additionally, research by Munro and Elsom (2000) indicated that both male and female students perceive science as preparing only useful specialists that provide no useful cultural knowledge. Therefore, we decided to emphasize the caring aspects of the female scientists we highlighted and the societal impacts of their work. For example, the teachers presented information about how Lisa Perez Jackson enacted clean air and water laws to improve the environment of others and how Patricia Bath helped many people blinded by cataracts to regain their vision. Women scientists' caring for animals was also highlighted. Examples included the concern that veterinarian Tolani Francisco had for her large animal patients, the affection Mary Leakey had for the charming African hyraxes that stole food from the dinner table, and Joan Esnayra's desire to help others with psychological problems through service animals. This approach resulted in a medium effect size change in student attitudes from pretest to posttest on the statement, "Women in science can make science more caring." An open-ended question on the pretest and posttest asked students to name well-known women scientists. On the pretest no students were able to name a woman scientist and her area of work. On the posttest, students were able to recall an average of three names of women scientists and their correct corresponding areas of work.

Attitude Surveys from Day 2 and Day 4
Before the class started, the professor sent an email message to all participants explaining that assessment data would be collected to evaluate the efficacy of the project (participants had been made aware of the data collection when they registered for the course), providing short descriptions of the eight women scientists on which the class focused, and asking for each students' top three choices of the eight scientists. This allowed the teachers to assign scientists for the student dioramas so that all eight were addressed in the class. Although a title and short description of the class had been available at registration, a few parents had not realized that the course focused on female scientists and they replied that their sons were concerned about whether there would be other boys in the class and whether they might choose a male scientist. The professor responded that half of the class was male, but that the topic would remain female scientists, as it was important for everyone to become aware of the often-overlooked contributions of women to science. Some male students were somewhat apprehensive at the start of class, but after the game that focused on scientists of both sexes and the exciting opportunity to paint the three-dimensional diorama with acrylic paints, everyone settled in quite happily. No complaints were made about the female scientist focus during the week. In fact, as the week progressed, the interest and pride of the boys in the women scientists on which they were concentrating was apparent as they often bragged to classmates about the accomplishments of their particular scientist while working on the diorama. Table 4 presents student ratings of creativity, enjoyment, and learning on the second and fourth days of class. Students were also asked to give two reasons for each of their ratings.
Student creativity and enjoyment of the course increased as students became more involved. Students felt most creative during the special activity designed to require creative thinking, the activity in which students made a scene using ten given craft items. However, there were other opportunities for students to work creatively. Each diorama base was somewhat different in size, as many different small boxes had been used to make the building on the front. Students, therefore, had to determine ways to fit the color images to the size and shape of box each had chosen. Arranging items on the panels of the box and in scenes was done individually, leaving room for creative expression.
The teachers observed that students were very engaged in the diorama work, especially the creative assignment of making something related to the scientist on the back of the box with the ten given materials. Twelve students stated that they used their imaginations to think of creative ways for using the given ten items as a reason for rating this activity high in creativity. Students expressed that they felt challenged, but were having a lot of fun completing the activity. This fits with the state of flow in which a person is challenged to use many available skills, resulting in a sense of timelessness, continuous flow of ideas, and deep satisfaction (Csikszentmihalyi, 1990). In fact, many students remarked that time passed very quickly when they were working on the dioramas. Table 4. Student mean ratings of creativity, enjoyment, and learning on a scale of "1" to "10" with "1" being "low" and "10" being "high".
In general, students found the diorama project very enjoyable. Students justified high enjoyment ratings by citing the fun of making a three-dimensional diorama and the challenge of using their imaginations to produce the creative scene on the back side. Students also referred to enjoyment of paint color mixing, paper image cutting, and glue work as highly enjoyable, particularly because they had few other opportunities for these types of activities. Teachers observed that students arrived each day ready to work on their dioramas. Sometimes it was difficult to get students to stop working and prepare to go to their next class. Students enjoyed the hands-on construction activities and expressed that they seldom have such opportunities at school. Many schools have eliminated arts-integrated model-making projects, replacing them with computer technology labs, or with more reading and mathematics lessons to prepare for high-stakes testing (Au, 2007;Spohn, 2008). However, a recent study found that students displayed more science content information through hands-on arts-integrated projects as compared to technology projects (Klopp et al., 2014).
Regarding science learning, students noted specific information about women scientists that they had retained. Ten students mentioned how the scientists had helped other people. One student remarked, "These people are really caring; I wish I could have known them." Five girls remarked that they were pleased to learn that female scientists are as capable as male scientists. A student working on a diorama of Ellen Ochoa was placing colorful red, white and silver stars on her diorama. She said, "All the scientists deserve stars because they are heroes in my eyes." A male student who was working on a diorama of a Nobel prize-winning scientist, asked the teacher for foam to separate the two sides of the medal he was gluing together so that the medal would look three-dimensional. He explained that the medal was an honor and he wanted it to be special for his scientist because she deserved it. Figure 10 and Figure 11 present some of the creative scenes made by students using the given set of ten craft items. After receiving the bag of items, students generated several possible themes for their scenes. Some students planned the scene carefully, while others took items one at a time and started construction. Most students had a couple of craft items that required more problem-solving to fit into the scene. However, almost everyone was able to incorporate at least parts of all ten items. Using all the provided items exercises the creative skill of fluency (generating many ideas). Another creative thinking skill is flexibility. This skill is evidenced when a student repurposes a material. For example, using the leaf as a tissue to wipe tears (Figure 10(d)) or part of a crystal pattern (Figure 11(d)), rather than as part of a plant, showed flexibility. Elaboration, attention to detail, was shown by the student who made the veterinary scene in Figure 10(c). He added decoration to the white fence, drew butterflies, sketched flower centers, and fringed the glitter foam to make tall grass. Some students made their scenes three-dimensional, another creative trait. The student in Figure 10 made a protruding red cover for a document; the student in Figure 10(d) had a pop-out ophthalmology machine; and the maker of Figure 11(c) showed a hair strand extending from the microscopic view. Many students used their imaginations to develop fantasy stories about their scenes. For example, the maker of the scene in Figure 10(d) imagined Ellen Ochoa traveling out of the regular shuttle orbit to "reach for the stars" by heading for the nearest star, the sun and the student creator of Figure 11(b) developed a story about his cave painting of a well-loved medicine man.

Additional Posttest Questions Involving Insight
At the end of the week, students responded to two additional questions on the posttest that called for their insights about the course. The first question was "What did you learn about women in science that surprised you?" Both female and male students provided the most frequent observation that women can be equal to men in science and help the world. The message that the investigators sent about women scientists being caring seemed to have been received. Several students named a specific accomplishment of a woman scientist that was studied such as Ellen Ochoa was Director of NASA, Barbara McClintock discovered jumping genes, Patricia Bath helped the blind, and Tolani Francisco worked on large wild animals. Students noted that many women scientists struggled against prejudice and unfair treatment, but diversity discrimination did not stop them. Another interesting response from one student was "they discovered things that I thought men discovered." This comment shows the previous mindset of the student that women had contributed little to science.
Responses to another question, "What new ideas or feelings about science do you now have?" revealed that many students now observed science as fun and exciting or that they had not enjoyed science previously, but now like it. Five students responded that scientists can help the world, again indicating that they now perceived successful women scientists as compassionate. These effects were highly desirable as student excitement about and positive regard for science are needed to encourage choice of careers in STEM fields. Four students also responded that they now believe that anyone, male or female, can become a scientist, in contrast to their earlier belief that all scientists are male. One 5-hour project is not likely to convert female students to planning a career in science, but it can be an effective link in the chain of events that leads in that direction.

Conclusion
Technology and standardized tests are an important reality in schools today, but educators must not forget that actively engaging students in hands-on creative activities is still a powerful learning tool necessary for wellrounded students. The imaginings our students participated in as they built the scenes of their dioramas are part of fantasy play, crucial for social, emotional, and cognitive development (Moyer, 2014). Imagining oneself in various careers, including its everyday work patterns, helps to prepare students for them and facilitates students being more patient and persistent (Bergen & Fromberg, 2009;Singer & Singer, 2006). Students found the diorama project highly engaging, increasing their knowledge of and appreciation for the contributions of women scientists. Students were also reported to have an increased desire for science careers. Therefore, the authors strongly recommend that teachers consider implementing this project with upper elementary students. Although the preparation for the project required several hours of researching the scientists, preparing electronic slide shows about them, and creation of example dioramas, with more time allotted to the work for students, much of this effort could be shifted to them with increased student benefits. The next section explains how this might be done.

Extensions and Cross-Curricular Applications
The researchers were heavily constrained by the one-week day camp model in which teachers had about 45 minutes a day for five days with the students. The investigators would have liked to have had additional time so that students could examine and learn about the women scientists the teachers had chosen, but then select and investigate a new female scientist on their own or in pairs, making a unique diorama on that person. However, the investigators had spent several hours researching scientists and locating appropriate images, so they knew that the day camp students would not have time to investigate a new scientist. The reader may want to extend the diorama project presented here to allow students to connect reading and writing skills to their investigations of women scientists. Common Core standards (Common Core State Standards Initiative, 2012) for fourth grade literacy addressed by student research are shown in Table 5. A checklist of what to ask students to find about the scientist would facilitate this work. Ideas for the checklist include: 1) Images: Find photographs of the scientist's face, of her working, of a building associated with her (perhaps a laboratory, office building, museum, university, home) and of the interior of the building (for the interior diorama scene); 2) Science work: Find out what science topics and concepts she worked on, what her contributions to science and society were, any awards she received, and objects associated with her work (for inclusion in the diorama scenes); 3) Personal: locate information about her personality, the challenges she faced, her education path to her science career, what she cared about most, and any interesting quotes from her.
