An interactive tool where students can create a model of a greenhouse and use a light sensor to measure the amount of light it receives from a lamp at various times of the day. Temperature is also measured. Data is plotted on graphs,...

Here is a large collection of simple science class activities for understanding the physics of light.

Why is light important? Play this interactive night light game with PEEP and observe why we need light to see objects. Also included are teaching tips.

How light waves demonstrate their wave nature by reflection, refraction, and diffraction.

Who uses light to communicate? Go from sea to shining sea as we visit a lighthouse, board a Navy ship, and take a stroll on the red carpet! Students will investigate different ways of communicating with light and at the end of the lesson...

An interactive simulation that teaches about molecules, photons, and absorption by exploring how light interacts with molecules in our atmosphere. Through this simulation students can get a better understanding of the importance of the...

Explore bending of light between two media with different indices of refraction. See how changing from air to water to glass changes the bending angle. Play with prisms of different shapes and make rainbows.

This tutorial reviews over the properties of light. Students will learn about reflection and refraction through videos, questions, and interactive activities.

You know how to make new colors by mixing paint or crayons. For example, you get green by mixing yellow and blue, or orange by mixing red and yellow. With paint, blue, yellow, and red are primary colors, which you can use to make other...

A 36-page booklet of activities and experiments for exploring the properties of and nature of light. Includes a section on careers in optics. As this is a Girl Scouts booklet, it was created with girls in mind, but would be equally...

[Free Registration/Login may be required to access all resource tools.] Students investigate the fundamentals of light including its source, how it is defined for measurements, how we perceive color, and the situations that make an...

What is light pollution and why should we care about it? Learn what it is, the different types, sources of this type of pollution, the impact it has, and ways to combat it.

You've probably heard that compact fluorescent light bulbs are more efficient than incandescent bulbs. More of the electricity they use goes into producing light, and less into producing heat than with incandescent bulbs. How much more...

Manipulate variables and measure angles as light is refracted in this interactive simulation.

Pinhole cameras are not a thing of the past. Even compared to all of the latest technology, a pinhole camera still gets beautiful results. Find out how this very simple aperture design works to control the way light enters the lens of...

In this experiment, you will measure the speed of light using a microwave oven, some egg white, and a ruler. This short project proves to be an extremely interesting choice for a science lab, with pictures for illustration, and thorough...

Multiple activities help students gain a better understanding of light bulbs and the many uses of artificial light. Click on the links provided for further exploration.

Learn why natural light is and why it is important by completing these five activities. Click on one of the many links provided for further information.

Learners investigate light waves. Some topics examined are reflection of light, illuminance, and refraction of light. The resource includes example problems with solutions and a chapter quiz.

An interactive PowerPoint will be used to introduce the electromagnetic spectrum. Young scholars use UV beads to observe changes caused by the sun's rays and evaluate sunscreen effectiveness. Harmful effects of UV exposure will be...

This is the first lesson of this unit to introduce light. In this lesson, learners learn the five words that describe how light interacts with objects: "transparent," "translucent," "opaque," "reflection" and "refraction."

In this lesson plan, the electromagnetic spectrum is explained and students learn that visible light makes up only a portion of this wide spectrum. Students also learn that engineers use electromagnetic waves for many different...

Learn how light impacts human hormones during sleep, and how it may prevent a drug called Tamoxifen from working.

An interactive look at our atmosphere and factors which affect planet Earth. NASA measurements of volcanic eruptions, toxic emissions, aerosols, and wind patterns are all graphically displayed. Basic text plus bold visuals make this...
