Several subjects are addressed within the context of a science lesson about the sun's ultraviolet rays. Elementary earth scientists consider protection of the skin with sunscreens (health), estimating and measuring surface area or an...

How effective are cells at repairing UV damage? An inquiry-based activity has learners experiment with organism by exposing them to various levels of UV light and then examining their DNA after a period of time. Pupils test different...

Students use the topic of sunscreen to explore the "issues related to size and scale" as energy and matter interact. They compare the visible opacity of different substances to their ability to block ultraviolet radiation.

Students explore Ultraviolet detecting beads and conduct several investigations with them.  In this investigative instructional activity students participate in an experiment to see the harmful effects of UV light and discuss their...

Middle schoolers identify and define that invisible UV rays can be harmful. Then they explore the effects of UV radiation on objects that react UV rays and what products are most effective in blocking UV rays. Students also make...

Students recognize preventitive measures that can be taken to reduce the risks associated with exposure to solar radiation. They explain why solar radiation can be harmful. They utilize beads that turn color when exposed to UV rays. Good...

Students compare the perceived and actual risks of getting skin cancer, while looking at ways to minimize these risks. They may have very little grasp of the severity of the threat of skin cancer or be unaware of the increase in the...

Students identify the different energy given off by the sun. In this earth science lesson, students predict where the UV beads will turn the darkest color. They explain the importance of using UV protection.

Students investigate radiant energy. In this earth science lesson, students use solar beads and clear sunscreen to observe radiant solar energy. Students note observations.

Students investigate how effective sunscreens and blocking devices are in blocking UV. In this physics lesson, students collect and graph their data from the experiment. They explain the harmful effects of UV radiation to everything...

Students explore the validity of claims of UV protection. Students research UV rays and the cancer danger presented by these rays. Working in groups, they perform tests on sunglass and sunscreen products to determine if their claim of UV...

Learners realize the importance of organisms as standards of measurement and experimentation.The first lab is a simple survival curve that demonstrates the effects of UV light on cells. The second lab looks at repair mechanisms of the...

First graders complete sunlight and solar effects activities to learn about light and its power. In this solar activity lesson, 1st graders complete a sunscreen test activity, a light test, a black light test, a cloudy test, a sunglasses...

Fifth graders read about how different animals protect themselves, and how characteristics give animals an advantage in their environment. Students then discuss a variety of "outer" wear for humans, and what they might choose to wear in...

Students investigate the sun's energy. They explore various websites, demonstrate proper solar protection, conduct experiments using special UV beads, and complete worksheets.

Twelfth graders use a microcomputer connected to an ultra-violet sensor to compare the relative blocking power of different SPF sunscreens for the UVB region of the solar spectrum.

Students test commercial sunscreens or sunglasses for accuracy of their Sun Protection Factor. They devise a method for testing UV beads with a visual clues which they publish as research. They investigate occupations such as...

High schoolers accurately measure the relationship between radiation dose and either survival or some genetic event such as mutation or recombination. They investigate the damage that was done to the DNA molecule as a result of exposure...

Students construct an interactive ozone depletion model using gumdrops and toothpicks. After analyzing the data obtained from the model, they record it on butcher paper and complete worksheets about oxygen.

Students discuss the physical properties of fluids and then demonstrate that air carbon dioxide and oxygen) is a fluid by creating currents.
