Date: 2/20/2013 and 2/21/2013
Class: Physical Science
Periods: B2,3 and W1,3,4
Outcomes: Calculate the IMA’s of levers, pulleys and ramps. Describe how machines change the force and distance of the work put into them.
Standards: UCP.1-3,5; A.1,2; B.1,4,6
Student Needs:
Assessment Plan: Lab Report
Lesson Outline: What is Energy? What is Work? How do Wedges change force? > How many of you have used a pulley system? Did it make your work easier? > Read directions for lab > Give students time to complete lab, may need help with pulley setup > What could have been done to decrease the input force for the highest ramp? > Begin Ch. 5 notes > Assign homework
Review: What is Energy? What is Work? How do Wedges change force?
Anticipatory Set/Opening: Lab Day. How many of you have used a pulley system?
Key Points:
Teaching Input: Asking questions, giving directions for lab and lab report
Modeling: Pulley and Ramp setup, data table setup
Checking for Understanding: Have students repeat directions, discussion at the end.
Guided Practice/Monitoring: Lab
Closure: What could have been done to decrease the input force for the highest ramp?
Independent Practice: Write 15 questions you think could be on the test. Write the answers on a different page.
