These scaffolded Radioactive Decay Cornell Doodle Notes combine two effective note-taking strategies and can be used to introduce the concepts of radioactivity and half-life, and the three types of radioactive decay (alpha, beta, and gamma). Students will learn what the word radioactive means, why atoms are radioactive, which elements have radioactive isotopes, the processes of transmutation by alpha and beta decay (using sample equations), that gamma rays are emitted during all decay, and the b
