Lesson 1: Intro to Momentum

Engagement: Think Time: Would it hurt more if you were hit by a fast bicycle or a slow truck?

Activity 1: Demonstration/Question Sequence: mass & velocity are both important

Activity 2: Notes: Momentum

Activity 3: Measure the momentum of a crash cart.

Homework:
Read Glencoe Physics (p. 199 – 204): section 9.1, *Calculating Momentum* worksheet

Lesson 2: Impulse

Engagement: Most of you are confusing force and momentum. Today we are going to learn how they are connected, and hopefully clear up any confusion.

Activity 1: Notes: Impulse-Momentum Theorem

Activity 2: Derivation of the Impulse-Momentum Theorem

Activity 3: Example Problem (p. 203): Stopping a vehicle

Homework: Read Glencoe Physics (p. 205-209): section 9.2

Chapter 9 Practice Problems (p. 204): 1, 2, 4, 5, 6

Lesson 3: Systems

Engagement: Think Time: What do you need to make a hamburger?

Activity 1: What is the system when I go bowling? I roll the ball only hit the corner pin.

Activity 2: Notes: Conservation of Momentum

Activity 3: Setup bowling alley problem.

Homework: *Systems* worksheet

Lesson 4: Conservation of Momentum: Elastic Collisions

Engagement: Car Crash: Animated Problem
Situation ← *Conservation of Momentum.ppt*

Activity 1: Example: Elastic Car
Crash ← *Conservation of Momentum.ppt*

Activity 2: Chapter 9 Practice Problems (p. 210): 11 & 12

Activity 3: Start the homework

Homework: Finish the practice problems

Lesson 5: Conservation of Momentum: Inelastic Collisions

Engagement: Demonstration: A student volunteer, standing on a skateboard, throws a medicine ball. What will happen?

Activity 1: Notes: Inelastic
equation: p_{total} = m_{total}v_{2}

Activity 2: Example: first practice problem

Activity 3: Chapter 9 Practice Problems (p. 210): 7-10

Homework: Finish the practice problems

Lesson 6: Collision Simulation Lab (Day 1)

Engagement: Today we are going to predict the outcome of collisions.

Activity 1: Play with the collision applet as a class.

Activity 2: Introduction/Review of lab instructions

Activity 3: *Collision Simulation Lab*

Homework: Finish lab predictions.

Lesson 7: Collision Simulation Lab (Day 2)

Engagement: Today we are going to test our predictions.

Activity 1: Test predictions on the internet

Activity 2: Conclusions: *Collision
Simulation Lab*

Activity 3: Start the homework early

Homework: Study for the test (make a note card)

Lesson 8: Assessment

Engagement: Today you get to show me how much you know.

Activity 1: Last minute review

Activity 2: *Momentum Test*

Activity 3: Reading assignment for the next unit

Homework: Reading questions from the next unit
