Date: 1/22/2013 and 1/23/2013
Class: Physical Science
Periods: B2,3 and W1,3,4
Outcomes: Students will be able draw a vector diagram and explain what happens when a person does a push up (assuming it’s not Chuck Norris).
Standards: UCP.1-3,5; A.1,2; B.2,4
Student Needs:
Assessment Plan: Ticket-to-leave: Draw a diagram showing what happens during a push-up and explain in words why the person “pushes themselves upward”
Lesson Outline: What direction is the frictional force if an object moves to the left? If the applied force is 10N but the net force is 8N, what is the frictional force? > Why does a football move in an arc? How does a rocket work? > Notes over Ch. 3 Sections 2 and 3 > Practice calculations problems > Ticket-to-leave: Draw a diagram showing what happens during a push-up and explain in words why the person “pushes themselves upward”
Review: What direction is the frictional force if an object moves to the left? If the applied force is 10N but the net force is 8N, what is the frictional force?
Anticipatory Set/Opening: Why does a football move in an arc? How does a rocket work?
Key Points: Equal and opposite forces aren’t always balanced because of inertia, conservation of momentum
Teaching Input: giving directions, asking questions, giving notes
Modeling: Diagrams on board, practice problems
Checking for Understanding: Have students repeat directions and randomly call on students to explain things in their own words
Guided Practice/Monitoring: Practice calculations
Closure: Ticket-to-leave: Draw a diagram showing what happens during a push-up and explain in words why the person “pushes themself upward”
Independent Practice: Study and finish problems
