Dig a hole, line it, fill it with fresh water, and you have a water hole: a good place to study colonization.

In this experiment, learners work in pairs to create two gloves -- one that contains a layer of shortening (blubber) inside, and one that doesn't.

In this lab, learners grow broad bean (also called fava bean) plants in three EarthBoxes for a few weeks before exposing one to wind (using a fan), another to heat (using a lamp), and the third to not

In this activity, learners construct a playable kazoo from inexpensive materials. They will experience how vibration creates sound waves and music.

In this hands-on activity, learners build their own kaleidoscopes and explore how light can reflect of off surfaces such as mirrors, to produce beautiful patterns.

In this activity, learners will experiment with the physics of flight by making a gliding contraption with strange looking wings. The activity explores flight with connections to the natural world.

This is an activity (located on page 3 of the PDF) about the mixture of materials in bone and how they affect its strength.
