Seventh graders model radioactive decay using pennies, collect data from their model, apply scientific visualization techniques to their data and create animated models explaining the concept of radioactive half-life.

In this detailed and comprehensive multi-day activity, budding evolutionary biologists use real data from lizard populations in the Canary Islands to examine evolution and natural selection. 

Students explore the different types of renewable and nonrenewable energy sources. In this earth science instructional activity, students discuss the pros and cons of each type. They conduct a variety of experiments on renewable energy.

Ninth graders research the different field of bioengineering. In this biology lesson, 9th graders differentiate meiosis and mitosis. They discuss the pros and cons of using radiation in medical diagnostics.

Twelfth graders research about the different careers in bioengineering. In this biology lesson, 12th graders identify the different stages in the cell cycle. They discuss the pros and cons of using radiation.

Students identify the different sources of radiation around us. In this physics lesson, students calculate their estimated radiation exposure per year. They research a current issue about radiation.

Students write and balance nuclear equations. In this chemistry lesson, students identify materials that block radiation using polymers. They collect and analyze data from the experiment.
