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.
