Date: 3/6/2013 and 3/7/2013
Class: Physical Science
Periods: B2,3 and W1,3,4
Outcomes: Students will describe how heat can be made useful.
Standards: UCP.1-3,5; A.1-2; B.2,4,5
Student Needs:
Assessment Plan: Students will write down how a refrigerator works.
Lesson Outline: B1,B2,W3 Quiz > What is the Law of Conservation of Energy? How can you tell how many outershell electrons an element has? If I give you mass and acceleration, what can you find? > Drinking Bird video > What are the 3 ways heat is transferred? Heat always flows from where to where? > Notes over sections 2 and 3 > Individual Project: write down research on how a refrigerator works, the parts involved and draw a diagram of it
Review: What is the Law of Conservation of Energy? How can you tell how many outershell electrons an element has? If I give you mass and acceleration, what can you find?
Anticipatory Set/Opening: SixtySymbols Drinking Bird Video. What are the 3 ways heat is transferred? Heat always flows from where to where?
Key Points: The amount of heat gained by a system is equal to the work done on it, heat ALWAYS moves from things with more thermal energy to things with less thermal energy.
Teaching Input: asking questions, giving directions, lecture
Modeling: Diagrams on board
Checking for Understanding: have students repeat directions, have students explain how refrigerators work
Guided Practice/Monitoring: Refrigerator research
Closure: Discussion over whether refrigerators violate the laws of thermodynamics
Independent Practice: Thermal Energy Worksheet
Reflection:
