Curated OER
Nuclear Reactions - Rutherford's Alpha Scattering Experiment
Neat! Show your physics class exactly how Ernest Rutherford fired alpha particles at a piece of gold foil and so determined that most of an atom is composed of empty space. Not just a slide show, but almost an animation, this...
Curated OER
Radioactivity, Time, and Age
Four activities demonstrate the chain reaction of nuclear fission to your physical science fans: falling dominoes, snapping mouse traps, throwing paper wads, and igniting a series of matches. They perform additional laboratory activities...

Nuclear Reaction Questions
These slides display 35 questions for a test or quiz on nuclear reactions. The topics covered assume that you have taught to quite a detailed level, with knowledge about research, common experiments, and the behavior and structure of...
Curated OER
The Life Cycle of a Star
In this stars worksheet, students read about the different stages in the life cycle of a star. Then students complete 3 short answer questions.
Curated OER
Radioactivity
In this radioactivity instructional activity, students write the mass number and atomic number for the missing element in the reactions. Students identify the isotope that is more stable and determine the half-life of the isotope. This...
