Trick your family and friends with this creepy crawler that moves up and down. In this activity, learners construct a circuit and motor device that will move a homemade spider in a spooky way.

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

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

In this activity, learners will build a simple electromagnet. They will test variables that would make the electromagnet stronger.

Before there were clocks, people used shadows to tell time. In this outdoor activity, learners will discover how to tell time using only a compass, a pencil, a handy printout, and a sunny day.

In this activity related to magnetism and electricity, learners discover that a magnet falls more slowly through a metallic tube than it does through a nonmetallic tube.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this activity, you'll make an electric motor--a simple version of the electric motors found in toys, tools, and appliances everywhere.

In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

In this activity, young learners investigate magnets. Learners discover that some magnets are stronger than others and that magnets have north and south poles.

In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.

In this activity, learners build a recording timer made from simple materials (e.g., small dc motor, sharpie pen, craft sticks, adding machine paper tape, etc.).

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

In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.

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 physics activity (page 3 of the PDF), learners will explore the concept of static electricity.

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.

In this activity, learners extract DNA from their own cheek cells, then create a rudimentary DNA profile similar to those seen on crime scene dramas.

In this physics activity (page 8 of the PDF), learners will make their very own working compass.

In this activity, learners discover that the Moon, like Earth, is made up of layers of different materials. Learners work in teams to make models of the interiors of the Moon and Earth.
