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

Learners will compare the growth rate and appearance of crystals forming on small rocks to those growing on miscellaneous objects. Learners will also investigate how temperature (warm vs.

Learners investigate how temperature affects the rate of chemical reactions by observing how steel wool reacts with various types of Kool-Aid solutions at different temperatures.

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 full inquiry activity (located on page 3 of the PDF under GPS: Kinetic Sculpture Challenge Activity), groups of learners will make predictions about which feature of a pendulum (mass, length,

In this activity learners explore surface tension. Why are certain objects able to float on the surface of water and how do detergents break the surface tension of water?

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.

Water sticks to all kinds of things in nature — flowers, leaves, spider webs - and doesn't stick to others, such as a duck's back.
