Resources• playdoughrecipe(seeteachersheet)•
Procedure:Set:10minutesBeforebeginningthisactivity,placetheingredientsonatablethatisviewablebystudents.AskStudents: Does anyone recognize these items I have placed on the table? Allow response time. What if I told you that we could take these ingredients and make something that is completely different than the individual ingredients? Do you think that we could do that? Do any of you know what we could make with these ingredients? Development:2classesHave pre-measured and labeled ingredients arranged on the table. Warn students that they are not making something they can eat. Remind them that although the ingredients are food ingredients, it does not mean that they should be able to eat them. First, allow students to approach the table and observe each of the ingredients being used. Once all students have looked at the ingredients, have groups of four or five students be responsible for one ingredient and allow them to take it back to their desks. Say to students: Now you need to look at your ingredient. What does it look like? What does it smell like? How does it feel? Do you think that once we combine it with the other ingredients it will be different or the same? Allow different students to describe each of the ingredients. You might

want to write their responses on a flipchart or blackboard. Discuss responses together. With help from students, combine all the ingredients in the pan and allow the students to make observations about the combined ingredients. Discuss observations together. Cook ingredients until the mixture has the consistency of mashed potatoes. Students may help, but make sure that they are wearing hot-mitts and eye protection. Turn the dough out onto waxed paper. When dough is cool enough to handle, allow students to take turns kneading it. Divide the dough among the groups so that all students are able to feel the consistency of it. Ask students:
• What does it feel like? • What do you think we have made? • Is this like any of the starting ingredients? Why or why not? • How is this substance different? • What would happen if we left out the water? Oil? Flour? • What do you think would happen if we added an extra cup of
flour? • How do you think we could find out? • Do you think that each of the parts or ingredients that we added
was important? • Do you see, smell, or feel any evidence of the original parts? • Do you think that we could divide the play dough back to the
original ingredients? Why or why not? • Has anyone ever seen parts put together to make a whole
substance that is different? Where and what? Be sure to record students' observations on a worksheet and discuss their responses to these questions with them. ExtendAllow students to play with the play dough and make their own creations. As students are working ask them questions such as.
• Was your creation unique? • How did using different parts allow you to make your creature
different than others? • How do the different parts or places on the island allow you to
make you creation unique? Closure:10minutesreviewanddiscusshowpartscanmakeawhole.
Evaluate • Would your creation change if you added a new part? • Would your creation change if you took a part away? • Are the parts that make up your creation needed to make it
special?

Give students some popcorn seeds and ask them to describe what they are seeing, feeling, smelling, and what characteristics the popcorn seed has. Have students practice writing characteristic words on worksheet provided. Teacher should write the words down on the board or on chart paper so students can copy them. Take some popcorn seeds and ask students to predict what they think will happen when we heat the kernels. Pop enough popcorn for the class and have them complete the second side of their charts with descriptive words describing what the kernel looks like once its popped. Ask questions: How did the kernel of popcorn change? Why do you think the kernel changed?
