Thursday, 2/11/19- A Day- Block Schedule Periods 2, 4, 6, &

Lesson Question:

What happens when objects collide? How can we design a crash protection device to absorb enough energy during a car crash to save lives?

Learning Tasks:

  1. Do Now– Get out your science notebook and add to the Table of Contents- Calculations p.60 (Left Side). Head page 60 properly with Calculations-Acceleration & Momentum-4/11/19
  2. Video Segments– “Physics of a Car Crash” and “Forces and Motion in an Underride Crash” (See Google Classroom for videos from JASON project)
  3. Field Assignment- Performing Crash Tests On the handout, calculate the acceleration for each car during each time intervals using the velocities in the data table. Using the graph, determine the time of impact for each car. Calculate the momentum of each car at the moment of impact assuming both cars have a mass of 1,500 kg.
  4. Notebook Work– Tape graph paper as a flip page to ISN p.61 and tape calculations handout as a flip page to ISN p.60.
  5. Putting Pieces Together– Take stock- Identify and consolidate ideas you have figured out across your investigations about motion. Put pieces together- Come to a consensus on how the pieces explain what happens when objects collide. Develop a public representation of how the pieces fit together.

Lesson Question:

What happens when objects collide? How can we design a crash protection device to absorb enough energy during a car crash to save lives?

Learning Tasks:

  1. Do Now– Get out your science notebook and open to p.61. Look over your observations of the two collisions in the T-chart. Turn to your partner and discuss what could be causing the differences that you observed between the two crashes.
  2. Field Assignment- Performing Crash Tests- Create two line graphs on graph paper from the velocity vs time data for the two car crashes in the videos. Label the x-axis as “time” and the y-axis as “velocity.” Use the graphs to describe what each car is doing during the particular time intervals and record on your graph paper. On the handout, calculate the acceleration for each car during those time intervals. Using the graph, determine the time of impact for each car. Calculate the momentum of each car at the moment of impact assuming both cars have a mass of 1,500 kg.
  3. Putting Pieces Together– Take stock- Identify and consolidate ideas you have figured out across your investigations about motion. Put pieces together- Come to a consensus on how the pieces explain what happens when objects collide. Develop a public representation of how the pieces fit together.

Tuesday, 4/2/19- B Day

Lesson Question:

What role does mass and velocity play in collisions?

Learning Tasks:

    1. Do Now– Copy down today’s Home Learning tasks in your planner. Get out your science notebook and add to the Table of Contents- “Examples p.58” (Left Side). Head page 59 properly with “Momentum-Examples-4/2/19.”
    2. Momentum Examples– How will the vehicles react in the following situations? 1. A large truck is stopped on road and a small car hits it from behind. 2. A small car is stopped and hit from behind by a large truck. 3. Two cars of equal mass moving at same speed collide head to head. Pair with your partner to discuss each situation and write a description of how the vehicles will react on ISN p.58. Be prepared to share with the class.
    3. Driving Question Summary Table– Complete the DQST on ISN pgs. 50-51 for the Momentum lab.
