In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

In this engineering challenge, learners design and build a crane out of cardboard to see how heavy a load it can lift.

In this activity, learners discover that some things only stand up while they are spinning.

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

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

In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.

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

In this activity about center of gravity (page 23 of PDF), learners investigate how the body adjusts to the force of gravity to remain balanced.

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

Computers are often used to put lists into some sort of order—for example, names into alphabetical order, appointments or e-mail by date, or items in numerical order.

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.

The goal of this Star Wars activity is to design and build a balancing device to help an Ewok escape the Imperial Forces by sliding down a tightrope to safety.

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!).

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

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 investigate balance and symmetry by designing a symmetrical butterfly, using a paper cutout.

In this activity, learners will perform various investigations to understand the vestibular-ocular reflex and learn about the importance of visual cues in maintaining 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.
