In this plant pigments worksheet, students compare the function of 3 types of pigments: chlorophylls, carotenoids, and phycobilins. This worksheet has 23 fill in the blank, 3 drawing, and 2 short answer questions.

Students discuss the mass-energy relationship based on Einstein's work. They calculate the energy released in various scenerios and sketch diagrams for the Lyman, Balmer and Pfund Series. In groups, they discuss the role of photons and...

In this atoms worksheet, students determine the velocity, wavelength, power, and frequency of given atoms. Student describe wave-particle duality and give the principle and angular quantum numbers for given orbitals. This worksheet has...

Students study solar energy.  In this renewable energy lesson students complete several lab activities using different controls and variables. 

This site provides information and activities for classes to learn more about ozone depletion and UV radiation.

Light! How do we see? What makes light? Find out everything you need to know through the Q&As on this site.

Sun tanning has a bad rap right now. Use a personal ultraviolet monitor to measure the UV index to prevent getting a sunburn. With this science fair project you will create a chart showing the UV ray measurement at different times of the...

Tutorial provides a discussion of UV-Vis spectroscopy, infrared (IR) spectroscopy, and the Beer-Lambert law.

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

Ultraviolet light can damage DNA molecules. If a cell's DNA repair mechanisms can't keep up with the damage, mutations are the result. As harmful mutations accumulate, the cell eventually dies. How much ultraviolet light is too much for...

In this science fair project, experiment with the role temperature plays in the rate at which UV beads lose their color. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction,...

This resource presents a discussion of the nature and properties of ultraviolet light. The manner in which minerals emit UV light is described and explained.

A map showing a view of the night sky is given; sources of extreme ultraviolet light are marked. Visitors analyze the spectrum from these parts of the sky and attempt to determine which star type the spectrum most closely resembles.

Ultraviolet (UV) light has shorter wavelengths than visible light. Though these waves are invisible to the human eye, some insects can see them. The specific wavelength values are given. Uses and applications of these waves are explained.

[Free Registration/Login may be required to access all resource tools.] Visible light and the different waves that make it up, infrared light and ultraviolet light.

In this activity, students learn how to prevent exposure to the Sun's harmful ultraviolet rays. Students will systematically test various sunscreens to determine the relationship between spf (sun protection factor) value and sun...

Using a student-teacher dialogue format, this page discusses the nature of light as an electromagnetic wave and the electromagnetic spectrum.

A discussion of ultraviolet light and its interaction with the atmosphere. Describes the UV detectors on a spacecraft which are used to study the UV light emissions from astronomical bodies.

Students learn the basics of the electromagnetic spectrum and how various types of electromagnetic waves are related in terms of wavelength and energy. In addition, they are introduced to the various types of waves that make up the...

Have you ever heard the expression "a canary in a coal mine"? In the 1900s and earlier, coal miners brought canaries with them into the mines to act as early warning signals. The canaries were very sensitive to low levels of dangerous...

Objects that glow in the dark hold a special place in the imagination of both children and adults. The lights go out at night, but these odd things refuse to disappear. Where does the light come from? Do they work in any climate? In this...

A website dedicated to answering questions about UV, climate, and the ozone layer. On this page, students can find answers to questions like: What is the state of the ozone layer? And, what factors affect the ozone layer?

In the APPI technique, UV light photons are used to ionize sample molecules.

Learn about the harmful effects on humans of ultraviolet radiation caused by the depletion of the ozone layer.
