Date: 10/23/2012 and 10/24/2012
Class: Physical Science
Periods: B2,3 and W1,3,4
Outcomes: Students will be able to explain how a nuclear reactor works, what critical mass is and why nuclear fusion can only occur in stars.
Standards: UCP.1-3,5; A.1,2; B.1,2,4; F.1; G.3
Student Needs:
Assessment Plan: Ticket-to-leave: Explain the differences between nuclear fusion and fission.
Lesson Outline: Review ask students what Bernoulli’s Principle is, what the 4 parts of an experiment are, what keeps a nucleus together and what causes it to become unstable > Ask students how a nuclear reactor works and what they know about nuclear reactions in the universe > notes over 18.3 and 18.4 > Practice finding the number of protons, neutrons and making full and outer shell electron dot diagrams > Ticket to Leave
Review: What is Bernoulli’s Principle, what are the 4 parts of an experiment, what holds a nucleus together and what causes it to break apart
Anticipatory Set/Opening: Video of atomic bomb testing, ask students what they know about nuclear reactions
Key Points: Fission involves a large nucleus being broken apart, fusion involves two small nuclei fusing together, chain reactions only occur when critical mass is reached
Teaching Input: Asking review questions and notes
Modeling: Diagram of critical mass, practice finding protons, neutrons,
Checking for Understanding: Have students explain directions
Guided Practice/Monitoring: P/N/E practice
Closure: Ticket to leave: Explain the differences between nuclear fusion and fission
Independent Practice: Study
Reflection:
