Date: 10/17/2012 and 10/18/2012
Class: Physical Science
Periods: B2, 3 and W1,3,4
Outcomes: Students will be able to describe the ways the 3 main forms of nuclear decay change a nucleus.
Standards:
Student Needs:
Assessment Plan: Students will predict what happens to a Uranium-238 nucleus that undergoes Beta decay.
Lesson Outline: Ask students what kind of graph is used to show changes over time, to explain Charles’s Law, what the 3 parts of an atom are and where each is located > Have students read Ch. 18 Sec 2 with a focus on what are the main forms of nuclear decay and how does each change a nucleus > notes over Sec. 2 > Practice nuclear transmutation
Review: Ask students what kind of graph is used to show changes over time; to explain Charles’s Law and a real life example; what are the 3 parts of an atom and where each is located
Anticipatory Set/Opening: The number of protons in a nucleus can change under very specific circumstances, how gold can be made from lead
Key Points: Alpha decay is a helium nucleus, Beta decay is an electron and Gamma is just energy and all 3 are ejected from unstable nuclei to form a more stable one
Teaching Input: Ask review questions, give directions for reading assignment and note-taking
Modeling: Give prepared notes
Checking for Understanding: Have students repeat directions
Guided Practice/Monitoring: Practice nuclear transmutations
Closure: Ask students which form of radiation they believe is the most dangerous to humans.
Independent Practice: Read Ch. 18 Sec 3
