What You See Is Not What You Get: The Difference Between Sunlight and Ultraviolet Radiation
Scientists have known that there is a difference between the sun’s visible radiation and invisible ultraviolet radiation from the sun. Ultraviolet radiation is separated into 3 types: UVA, UVB, and UVC. The scientists in this study were interested in trees growing in urban areas. They wanted to know whether the shade that we can see under urban trees protects people from UVB radiation.

Note To Educators
The Forest Service's Mission
The Forest Service’s mission is to sustain the health, diversity, and productivity of the Nation’s forests and grasslands to meet the needs of present and future generations. For more than 100 years, our motto has been “caring for the land and serving people.” The Forest Service, an agency of the U.S. Department of Agriculture (USDA), recognizes its responsibility to be engaged in efforts to connect youth to nature and to promote the development of science-based conservation education programs and materials nationwide.
What Is the Natural Inquirer?
Natural Inquirer is a science education resource journal to be used by students in grade 6 and up. Natural Inquirer contains articles describing environmental and natural resource research conducted by Forest Service scientists and their cooperators. These scientific journal articles have been reformatted to meet the needs of middle school students. The articles are easy to understand, are aesthetically pleasing to the eye, contain glossaries, and include hands-on activities. The goal of Natural Inquirer is to stimulate critical reading and thinking about scientific inquiry and investigation while teaching about ecology, the natural environment, and natural resources.
