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

Ninth graders perform a series of experiment to investigate heat transfer and phase changes. In this physical science lesson, 9th graders identify and calculate the different subatomic particles. They explain the importance of scientific...

Students simulate how scientists studied things they can't see like atoms. In this chemistry lesson, students predict what is inside the numbered obsertainers. They design a way to investigate what's inside without opening it.

Learners 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...
