Learn why the Sun keeps us healthy, and also, learn how the Sun can harm our skin, eyes, and immune system. Read about the dangers associated with the Sun's ultraviolet rays, and read tips to help you stay safe when outside in the summer...

Try this experiment to learn how to make things glow under a black light, why this happens, and some applications of this phenomenon.

The goal of this project is to measure the effectiveness of different sunscreen products for blocking ultraviolet-A (UVB) and ultraviolet-B (UVB) rays from sunlight. This project shows you how to use a UV detector to measure rays of light.

In this biotechnology science fair project, investigate how DNA damage affects growth of yeast that are DNA-repair deficient. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and...

Spanish content; this is an explanation of ultraviolet radiation and it's effect, in particular, in the region of Argentina.

What is electromagnetic radiation and how does it work? Review a captioned graphic that explains electromagnetic radiation and the visible and invisible types of radiation on the electromagnetic spectrum.

In this science experiment, find out what happens when you pour tonic and ice into a glass and shine a blacklight on it.

Read the passage and study the diagram to answer the five-question quiz that follows.

Provides a great overview of DNA damage from agents such as ultraviolet light, nuclear radiation, and certain chemicals. Includes DNA strand drawings.

This fact sheet provides a quick overview of the major health problems linked to overexposure to UV radiation: skin cancer (melanoma and nonmelanoma), premature aging of the skin and other skin problems, cataracts and other eye damage,...

In this activity, kids build a shelter from the sun and test it using a UV-sensitive bead animal they create. If the shaded animal changes colors, then your shelter did not work.

Test the effects of exposure to ultraviolet radiation on living cells by simulating the ozone hole in the lab, then consider how this information might apply to you.

The atmosphere interacts with ultraviolet light and incoming radiation as featured in this text.

This site from The Florida State University provides an informational page on electromagnetic radiation discusses the characteristics and properties of its many forms including X-rays, gamma rays, ultraviolet radiation, infrared...

A brief summary and illustrations of light and how the lights rays are reflected and bent.

This site from Georgia State University discusses the location of visible light on the electromagnetic spectrum. Includes the wavelength values for various colors of light within the visible light spectrum.

This picture shows the colors in the visible spectrum. Human's eyes can see light in this range but we are unable to see other light such as infra-red and UV without the aid of scientific equipment.

Middle schoolers are introduced to the electromagnetic spectrum through this group research activity. Each group investigates a different wavelength range within the em spectrum and reports back to class. Discussion ideas also included.

Sunburn isn't just painful, it's dangerous. Learn about the connection between sun exposure and skin cancer, and learn how treat sunburn. Also, learn how to prevent getting sunburn with three simple tips. Use the links on this page to...

Professor Beder's 1992 book describes the problems and causes of ozone depletion. Find out how ozone depletion affects the environment.

In this interactive, learn about sources of both beneficial and harmful radiation which exist in many forms all around us.

This activity explores the equilibrium of dyes that self-assemble into DNA templates. Students use knowledge of equilibrium and quantitative spectroscopy to explore different dyes that bind selectively to DNA molecules. In this activity,...

Ozone in the stratosphere protects the earth by absorbing harmful ultraviolet radiation from the sun. However, when ozone occurs in the troposphere, it is harmful to health. In this project you can use data from EPA monitoring stations...

Using gumdrops and toothpicks, students conduct a large-group, interactive ozone depletion model. Students explore the dynamic and competing upper atmospheric roles of the protective ozone layer, the sun's UV radiation and harmful...
