How much radiation are we exposed to every day? Find out in this video segment adapted from FRONTLINE: "Nuclear Reaction." [1:46]

This site has lesson plans and activities related to radiation. Activities include measuring radiation with a Geiger counter and observing radiation 'footprints' in a cloud chamber.

An interactive simulation that teaches about electromagnetic radiation, dipole radiation, and electric fields by observing the effects of changes in sinusoidal, circular, and linear motion on the outward propagation of radiation. This...

Use this study guide to understand extinction and radiation of life.

[Free Registration/Login may be required to access all resource tools.] Students investigate the characteristics of radioactive emissions, and then complete equations involving radioactive decay when given pertinent information.

Explains the concept of heat transfer and describes conduction, convection, and radiation which are the three modes of heat transfer. Includes formulas, examples, and applications.

Explains how radiation is produced and the characteristics of alpha, beta, and gamma radiation.

Kids learn about the science of radioactivity and radiation in chemistry including radioactive decay, types, measurements, half-life, and the dangers.

The students will evaluate their personal radiation dose. They will develop an understanding of the term radiation and how it relates to everyday life. The will simulate how radioactive material decays and apply the term half-life....

Electromagnetic radiation waves are found all around us. Young researchers will discover more about these energy waves with these highlights.

Briefly explains the different types of radiation in the electromagnetic spectrum.

Describes how terahertz radiation, or T-rays, are used to detect hidden objects, including revealing a hidden painting, illegal materials in a piece of luggage, and defects on a space shuttle.

This article with embedded videos provides information about three main types of radioactive decay: alpha, beta, and gamma.

Learners will design a controlled experiment to demonstrate the greenhouse effect and the effect of different surfaces on light reflection.

We all know that plants need sunlight and water to grow big and tall. But did you know that inside seeds are baby plants, and that the fragile baby plant inside the seed needs to be protected? If you've ever had a sunburn, you also know...

Through a teacher demonstration using water, heat and food coloring, students see how convection moves the energy of the Sun from its core outwards. Students learn about the three different modes of heat transfer (convection, conduction,...

This site provides a great series on the neutron discovered by James Chadwick. Includes a seven-page series that covers what is inside the nucleus, the elusive neutron, beryllium radiation, Chadwick's discovery, neutrons from beryllium,...

Do you understand the relationship between temperature and carbon dioxide in our atmosphere? This computer model shows factors such as clouds and carbon dioxide that could cause global temperatures to rise. Students investigate how the...

Energy is transmitted by conduction, convection or radiation.The conductivity of materials can be compared by examining the time taken to transmit energy through them. This lesson explains how conduction works and provides a link to a test.

Discusses the methods the human body uses to regulate body temperature. Includes links to the four external heat transfer mechanisms (radiation, conduction, convection, and evaporation of perspiration).

This lesson discusses how electromagnetic radiation transfer the sun's energy to earth. This lesson will also talk about the eight types of electromagnetic waves in the electromagnetic spectrum and how each type is used or found in our...

Very informative article about dirty bombs, containing a conceptual description of how they are made, along with a discussion of the potential health effects associated with a dirty bomb attack.

This tour divides the Smithsonian's collection of 278 radiator emblems into different groupings to demonstrate how similar objects can be interpreted to emphasize certain themes and relationships. The exhibition uses the radiator emblems...

Learn about the harmful effects of low doses of radiation, if any.
