Teach about Force and Motion with Kindergarten STEM! Amazing resource for STEM club, STEM teachers, elementary librarians, parents who love hands-on learning, and elementary teachers who want to create a hands-on educational environment in their classroom! In the story, Ricky could’t roll like all of the other rocks because of his shape. Ricky’s friends added different materials to Ricky to change his shape. In this STEM Challenge, students add materials to help their rock roll better. Then, they examine how to push and pull their rock. This STEM Challenge aligns to NGSS Engineering Standards for Kindergarten, but can be used in 1st grade.
