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.

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

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

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.

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

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 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 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.

This board game teaches learners about energy decision making. Players select cards that determine the transportation and home design that will influence their expenses as they play.

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.

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.
