Overview

Construct a model that helps reduce the momentum on an object or objects in a collision.

Objectives and Goals

Procedure

  1. Today, we are going to learn about two professions that need to understand the physics of car crashes, but from two vastly different angles. As you watch the next videos, consider what kind of research you would need to do on the laws we've been studying in order to be successful at these jobs.

  2. Think of a job you are interested in pursuing or find fascinating. 
  3. Highlight how that occupation institutes safety procedures to reduce momentum on an object, and explain why those safety precautions are essential to that job.
  4. Now it's time to design your own collision model. (Inanimate objects only!) This collision example should be one that could occur at the job you choose. It should also be one that would require safety measures.
  5. Create three collisions, improving your safety precautions with each trial:

Use the Safety First Engineering Instructions (Links to an external site.) to help guide your experiment. Make sure to check the rubric (Links to an external site.) at the bottom of the page before designing and again before submission.

Experimental Design

Design shows the learner has analyzed the problem and has independently designed and conducted a thoughtful experiment. 



Design shows learner grasps the basic idea of the scientific process by conducting an experiment that controlled obvious variables.

Design shows that the learner grasps the basic idea of the scientific process but needs some help in controlling obvious variables.

Design shows learners can conduct an experiment when given considerable help by the instructor.

Data Analysis & Summary

Data was collected and recorded in an orderly manner that accurately reflects the results of the experiment. 

Data was recorded in a manner probably represents the results of the experiment.

Data was recorded in a disorganized manner or only with instructor assistance 

Data was recorded in an incomplete, haphazard manner or only after considerable teacher assistance.
