Date: 2/12/14 and 2/13/14
Class: Physical Science
Periods: W1,2,4 and B2
Outcomes: Students will calculate GPE and KE of falling objects and diagram changes in GPE and KE of a pendulum.
Standards: 9-12.P.2.3
Student Needs:
Assessment Plan: Lab report
Lesson Outline: Ask students What is Kinetic Energy? What is Potential Energy? What are the 3 forms of Potential Energy? > Notes over Ch. 4 > Lab Activity (falling and pendulum) > Finish Ch. 4 Review
Review: Ask students What is Energy? What is Kinetic Energy? What is Potential Energy? What are the 3 forms of Potential Energy?
Anticipatory Set/Opening: Pendulum in the middle of the room
Key Points: As things fall, their GPE is transformed into KE, pendulums and swings involve several changes in energy
Teaching Input: asking review questions, giving directions for lab: measure a certain height and mark it on the wall (aim for between 2m and 3m) > time how long it takes for the object to fall that distance > calculate the GPE of the object using mgh and then KE using the average speed as it fell so d/t to get v then 0.5mv^2 > demonstrate pendulum
Modeling: Demonstrate setup, calculations and pendulum
Checking for Understanding: have students repeat directions
Guided Practice/Monitoring: Lab activity and practice problems
Closure: Discuss why pendulums stop and why their GPE’s and KE’s might not match
Independent Practice: Partner up on Ch. 4 Review
