Are these two light sources the same? Groups use a white card and a little cooking oil to create a photometer that allows for the comparison of two lights. The Inverse Square Law provides a way to calculate the actual difference in...

Kindle knowledge of how light travels by using this activity in your physical science curriculum. By setting up a candle flame or flashlight bulb and viewing it through a slit, observers of light see evidence of its wave characteristic....

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...

Reflected waves of light move within a plane, and because of this, polarizing materials can reduce the glare our eyes see. This resource explains how to set up a demonstration of this effect. Consider it for use in your physical science...

With a Florence flask or fishbowl, make a double convex lens and use it to examine an image. Because of the refraction, the image will be inverted. A simple explanation is provided here for you to share with your class as they...

What is the difference between a form of energy and a source of energy? This first activity in a series of 19 lessons uses demonstrations and discussions to introduce energy to the class. Through using hand-generator flashlights,...

Only 10 percent of an incandescent bulb's energy is used to create light; the remaining 90 percent is heat. In the unit of activities, young chemists examine energy through hands-on activities, videos, discussions, and...

Turn your classroom into a live demonstration of how the earth and sun interact to create the four seasons. Using a globe, a light source, and a series of constellation cards, super scientists discover how the...

Shine some light on the topic of seasonal change with this collection of activities. Whether it's by measuring the change in the length of their shadows, or modeling the earth's orbit around the sun using a lamp and a globe, these...

First in a two-part lesson on the greenhouse effect, this lesson involves a classroom demonstration of the phenomenon, and a lab group experiment with color and absorption. Although there are easier ways to demonstrate the greenhouse...

An informative physics lesson includes two teacher demonstrations, one on AC currents and the other on DC currents, allowing pupils to take notes while watching. The resource includes questions to assign as homework or...

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...

Orange you glad you can make circuits using fruit? Young electricians learn about electric circuits and electricity. As part of the lesson, they build a circuit with an orange and then with a banana.

Young scholars explain the concepts and vocabulary of Earth's rotation. They plan imaginary vacations based on the seasons in different locations. This is a very creative lesson plan, which students enjoy.
