The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

In this activity, learners explore clouds and how they form.

In this activity, learners model hot spot island formation, orientation and progression with condiments.

In this geology activity learners build a "squeeze box," which allows them to compress layers of sediment. This is a great way to investigate folding and faulting in the Earth.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.

In this activity, learners explore how distance can affect the way we perceive the size of an object.
