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.

In this activity, learners build a simple tabletop seesaw to test how different variables (the position of the fulcrum, distance, weight) affect its balance under increasing weight loads.

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.

This activity models the necessary balance of creating power and cleaning up its associated waste. Learners participate in a game where they attempt to move forward toward a goal.

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

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

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 design activity, learners create a vehicle that can transport a load, like a favorite toy or as a recycled object, from the top of a zipline to the bottom using only gravity.

In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.
