I found this recipe for GOOP on Pinterest. I changed the recipe a little. I did not want to use 2 cups of cornstarch, so I used 1/2 cup of cornstarch and 1 cup of water.
Addison played with this for a little while, but said it was not like the GOOP they made in school.
I probably would not make this again. I think younger kids would like to play with it more, but for my six year old she thought it was kind of boring.
If anyone has any other fun science projects for kindergarten age girls, I'd love to hear them!
