In this lesson students are introduced to radioactivity and the types of radiation. There are no nuclear equations in this lesson. The main concept is to get students thinking about what changes are occurring within the nucleus with each type of radiation. The lesson includes the 3 main types of radiation; alpha, beta, and gamma – plus, positron, neutron, and proton emissions, and K-capture. The band of stability is discussed. In this lesson we want students to concentrate on the nucleus and what changes are being made. At the beginning of the lesson, a comparison of chemical reactions and nuclear reactions is presented.
Lesson Objectives:
* Compare chemical reactions and nuclear reactions
* Describe how the strong nuclear force and electrostatic forces affect the nucleus
* Describe nuclear stability as it relates to the Band of Stability
* Identify and describe the Three major types of nuclear radiation with regards to: symbol, effect on the nucleus, danger, and protection
* Identify and describe other nuclear emissions such as positron, neutron, and proton
* Describe electron capture (K-Capture)
