Second graders acknowledged that Mrs. Brinza's play-doh was too sticky and too gritty, and that we should do three tests to determine if the properties of our home-made play-doh were up to par with the properties of store-bought play-doh.
Using ten steps, students used the engineering design process to improve how the play-doh was made to get the best possible product!
SUCCESS! Our new play-doh wasn't as gritty or as sticky. Way to go second grade!
