Learners explore the concepts of equilibrium and center of mass by seeing how non-symmetrical objects balance.

In this activity, challenge learners to make a pencil stand on its tip using only two pieces of wire and two clothespins. Use this activity to demonstrate the center of gravity.

In this activity, learners will build the highest tower they can out of recycled materials.

In this science trick, learners get an egg to stand-up on its long-axis vertical to a table's top.

In this design challenge activity, learners build a device to carry a Ping-Pong ball from the top of a zip line to the bottom in four seconds (or less!).

In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.

This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.

In this activity, learners investigate balance and symmetry by designing a symmetrical butterfly, using a paper cutout.

In this quick activity, learners take a balance challenge to measure their average balance time. As they collect data, they investigate how practice and repetition improve their balance time.

In this activity, learners make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight.

In this quick and simple activity, learners explore how the distribution of the mass of an object determines the position of its center of gravity, its angular momentum, and your ability to balance it

In this activity and/or demonstration, learners illustrate visually and physically that air has weight. Learners balance two equally-inflated balloons hanging from string on a yard stick.

In this activity and game, learners will train to improve balance and spatial awareness by performing throwing and catching techniques on one foot.

In this online activity, learners partner up to complete several physical exercises and assess their starting fitness level.

In this physics activity (page 6 of the PDF), learners will build a class 1 lever and hypothesize and test the distances two objects need to be placed from the fulcrum in order to balance.

During this activity, learners take part in a variety of tasks which involve moving and balancing different body parts.

This is an activity about center of gravity. Learners will balance a fork on a glass by finding its center of gravity.

A simple, yet fun activity that lets learners find the center of balance of a ruler (or any long thin object). Developed by the Exploratorium and no assembly needed.

In this activity, learners balance chemical equations and discover the law of conservation of mass. Learners use coins to model molecules to balance the equations.
