Get your hands on electricity. Pupils investigate magnetic fields and make the connection to generators in the fourth lesson in a series of six lessons on wind versus solar energy. Learners use a small electric motor as a generator to...

Careful, that light bulb is hot! Compare heat and light energy using a simple light bulb. The exercise addresses energy conservation and presents actual calculations to determine the most cost-effective light bulb.

Three astronomy activities in one resource! Here you will find one hands-on activity, one demonstration, both with discussion questions, and one activity worksheet. During these lessons young scientists discuss how stars are...

The inverse square law is revealed when your class participates in this activity. They move a graph paper or perfboard square back and forth in a square of light to see how the intensity changes. You will definitely want to add this...

How much energy does it take to light a room? Class members calculate the total wattage it takes to light the classroom. Through calculations, responsible scientists determine the cost of energy for the year, then figure out...

Let there be light—or maybe not. Pupils learn about light pollution with an investigation of constellations. They create constellation boxes and experiment with different levels of light. Observations are then made about the lighting in...

Hear from deep space. Pupils learn how satellites transfer information back to Earth. They learn about three different ways to modulate radio waves and how a satellite sends information with only 0s and 1s. Using sound, class members...

In this second of three lessons on power plants, future engineers find out how we generate electricity and how coal-powered plants operate. They work in small groups to make electromagnet generators to light LED bulbs. A set of...

Using a dimmed flashlight, life science learners can see the network of blood vessels that line the back of their eye. Darken the room and let them try this activity as part of your unit on the eyeball. Also consider some of the other...

Don't be shocked when your class has a blast making their own batteries! Science scholars examine a dry cell battery, then design and construct a wet cell battery. The activity guides them through the parts of a battery, the variables...
