Date: 1/11/2012 and 1/14/2012
Class: Physical Science
Periods: B2,3 and W1,3,4
Outcomes: Students will explain the relationship between mass, acceleration and force. They will also explain friction in terms of force and direction.
Standards: UCP.1-3,5; A.1,2; B.2,4
Student Needs:
Assessment Plan: Ticket to leave: Draw a vector diagram showing velocity and force for an object that is slowing down.
Lesson Outline: Individually, figure out the velocity of an object that travels 10m to the right in 5s > What is the acceleration of the object if it took 4s too get up to that velocity? > Vectors video > What do you think friction is? > Read Ch. 3 Sec. 1 pages 68-74 and write about how friction effects net force > Notes over Ch. 3 Sec. 1 > Put force equation on notecard > Read Sec. 2 pages 75-82
Review: Individually, figure out the velocity of an object that travels 10m to the right in 5s > What is the acceleration of the object if it took 4s too get up to that velocity?
Anticipatory Set/Opening: Vectors video > What do you think friction is?
Key Points: f=ma; friction is a force in the opposite direction of movement
Teaching Input: asking questions, giving directions, explaining video
Modeling: equations in Review and the new force equation
Checking for Understanding: have students repeat directions, writing about how friction effects net force
Guided Practice/Monitoring: Read Ch. 1 and answer question
Closure: discuss how friction and air resistance are related
Independent Practice: Read Ch. 3 Sec 2 pgs 75-82
