In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers. Note: this activity requires adult...

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer. Use this activity to demonstrate how hot air rises due to density and how the volume of...

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon. Learners role play as miners, power plant operators, car drivers, and home...

In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color. In the first experiment, learners will see how liquid crystals...

In this activity, learners string a line across the room and build cable cars that can move from on end to the other. Learners construct their cable cars out of wood sticks, motors, and electrical...

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate. Learners will construct a turbine that is not strong enough to operate an electrical...

In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities. Learners demonstrate wave motion in...

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness. Learners explore surface area, nanostructures, and work in...
