In this activity (2nd activity on the page), learners explore how the nose is responsible for part of the flavor we taste in food.

In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.
