Mold your learners into materials engineers. Using glue, Borax, and water, scholars create a viscoelastic material. But your class might know it by another name—Silly Putty.

You'll bounce off the walls with glee after finding a fun resource. Young engineers design trampolines for golf balls. They build and test out their design and make improvements based on the results.
