Dangers of Radiation Exposure

Gamma radiation, which is harmful, is useful in treating cancers. In the second instructional activity in a series of four, young scientists take surveys and calculate their yearly exposure to ionizing radiation. Then they read about how...

Students investigate the effects of radiation exposure and how it can effect objects on earth and space. They conduct research using a variety of resources and use the information to create a project that is reflective of good research...

NASA landed on the moon with computers less powerful than today's cell phones. An informative video offers an entertaining look at the dangers and concerns of being an astronaut. The cartoon graphics are amusing and the science is sound. 

Not all radiation is hazardous. Electromagnetic radiation is pure energy. Nuclear radiation comes from the atomic nucleus in which isotopes become unstable and radioactive. Share this video with your class to explore the types of...

Students distinguish safe forms of radiation from those that are dangerous. They watch a video about sources of radiation encountered every day. They estimate their own annual radiation exposure.

Students investigate the dangers of radiation by exploring recent nuclear tragedies.  In this scientific debate lesson, students define the idea of radiation "half life" and determine if low doses of radiation are truly damaging to a...

Students evaluate the ways to control exposure to radiation and determine how to deal with the problem of nuclear waste in a rational rather than an emotional way.

Students list some of the health effects of radiation exposure. They are engaged in a unit on nuclear power by demonstrating the potential environmental health risks involved.

Students work in small groups researching different aspects of the sun and skin. The groups summarize and answer questions about the material in a presentation to the class.

Students explore current events by sharing information about the Japanese nuclear plant. In this nuclear energy lesson, students discuss the pros and cons of nuclear energy plants and whether or not they can typically withstand natural...
