Radiation Energy
Eighth graders experiment with a Geiger counter and a dosimeter to test the amount of radiation in a room and the amount of radiation received in a day. In this radiation energy lesson plan, 8th graders test the shielding effect of...

Not In My Backyard: The Nature and Danger of Nuclear Radiation
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.
Curated OER
Electromagnetic Radiation
Students explore the nature of electromagnetic spectrum through a series of experiments. In this physics lesson plan, students determine how light behaves under certain circumstances. They explain how humans perceive colors.

Get the Picture!
Astronomers practice downloading data from a high-energy satellite and translate the data into colored or shaded pixels. As a hands-on activity, they use pennies to simulate high-energy satellite data and they convert their penny...

RADIATION PROTECTION: HOW MUCH IS ENOUGH?
Students study the effects of shielding on the amount of detectable radioactivity from a gamma source. They investigate the shielding of one type of metal, then design their own experiments to answer questions raised during the...
Curated OER
Radiation Reassessed
Students investigate the dangers of radiation by exploring recent nuclear tragedies. In this scientific debate lesson plan, students define the idea of radiation "half life" and determine if low doses of radiation are truly damaging to...
Curated OER
Radioactivity Experiments
Students study the difference between types of ionizing radiation and how elements are transmuted. They determine that radiation is normal and surrounds us. They calculate the amounts of alpha, beta and gamma radiation emitted from a...
Curated OER
Radioactive Samples
Students examine the different types of radioactivity. In this radioactive samples lesson students complete a lab activity on radiation and complete a handout.
Curated OER
Check Out Lights and Shields with Beads
Students explore Ultraviolet detecting beads and conduct several investigations with them. In this investigative lesson students participate in an experiment to see the harmful effects of UV light and discuss their findings.

Can You See Beyond the Rainbow?
There's more to light than ROYGBIV! An enlightening laboratory investigation has learners explore the world of infrared light. When they use goggles that take away visible light, they experience how things look with only infrared light.
Curated OER
In Search of Cosmic Rays
Learners compare rates to altitude. They conduct a class discussion about the results.

SURVIVING A COSMIC INVASION
Pupils read periodicals relating to radioacitivity and interpret a Geiger Counter. They work in small groups, share information and help each other explain the Geiger Counter. They discover the relationship distance to bombardment/contact.

Is There Life Before 121?
Students observe microbial growth in the lab. In this biology lesson plan, students determine the conditions suitable for bacterial growth. They explain the methods of sterilization and bioburden testing.
