In this colorful activity (page 6 of the PDF), learners will make a multicolor density column by using different concentrations of sugar solutions.

In this physics activity, learners will explore the concept of buoyancy, especially as it relates to density.

In this activity, learners will design a protective package for an egg that will allow the egg to withstand a fall without cracking.

In this activity, learners will build a simple electromagnet. They will test variables that would make the electromagnet stronger.

In this physics activity, learners experiment with pulleys and find that they can decrease the effort needed when using a pulley to lift or move different loads.

In this physics activity (page 8 of the PDF), learners will make their very own working compass.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

In this physics activity, learners will gain a better understanding of how friction, inertia, and mass affect objects.

In this chemistry activity, learners will test the pH of various foods and household substances using cabbage.

In this geology activity (page 3 of the PDF), learners simulate an earthquake with little more than an elastic band and drinking straws.

What keeps bubbles and other things, like airplanes, floating or flying in the air?

In this physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.

In this biology experiment, learners plant soybean seeds in plaster of Paris, witnessing firsthand the mighty power and ability of plants to grow in adverse conditions.

In this physics activity (page 8 of the PDF), learners will explore the concept of inertia by attempting to run and stop quickly.

In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.

In this activity about weights and balances, learners create their own balance using paper cups. Then, learners explore how to compare the relative mass of objects.

In this physics activity, learners will build their own parachutes out of tissue paper. They will explore the effects of weight, height, and design on the parachutes' speed and stability.

In this playful physics activity (page eight of the pdf), learners use toy cars to explore how speed and weight affect the results of collision.

In this physics activity, learners will investigate the strength of egg shells.

In this activity about states of matter, learners get to witness firsthand the awesome power of air pressure. They watch as an ordinary soda can is crushed by invisible forces.
