In this delicious activity, learners get to make, taste-test and compare their own "brands" of homemade strawberry ice cream.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this hands-on science experiment, students combine their understanding of the different states of matter and the characteristics of various chemical reactions.

Learners explore soybeans, soak them in water to remove their coat, and then split them open to look inside. They also make a musical shaker out of paper cups, a cardboard tube, and soybeans.

In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.
