So the second graders have created their tests...and now it's time to investigate the materials used to make play-doh!
The three ingredients we will be using to make play-doh are flour, salt, and water. Students determined the properties of each material by observing them with their sense of sight and their sense of touch. They also hypothesized what each material would do to the mixture.
Second graders agreed that:
1. Adding more salt would make the play-doh grittier, since it felt like sand.
2. Adding more flour would make the play-doh drier and possibly softer since it didn't feel wet or hard.
3. Adding more water would make the play-doh stickier because it was wet!
Now on to make some play-doh!
