Learners construct an electricity-generating wind turbine out of a plastic bottle.

In this activity, learners explore how wind energy can be generated on both a large and small scale.

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.

This activity guide includes instructions on how to build a "Shake Table" by mounting an eccentric mass (off center) on the shaft of a small dc motor.

Learners build a wind turbine and test it to see how much energy is created.

Learners explore how recyclers take advantage of the different properties of materials, such as magnetism and density, to separate them from a mixture.

In this activity, learners use simple materials to build their own compass.

In this activity, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.

In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.

In this activity, learners conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.

This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.

In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from

In this activity on page 12 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners examine how recyclable materials are separated by various properties at recycling centers.

In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.

In this activity, learners make a 3-D model of magnetic fields by inserting a small, strong magnet into a sphere.

In this activity, learners assemble large cubes to make nano-related images. Learners discover how different objects are related to nanoscience and nanotechnology.

In this activity, learners simulate the separation techniques that materials recovery facilities (MRFs) use and then design their own series of recycling techniques.

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.
