### Buckle Up!

### Objectives and Goals

- Examine and explain evidence of Newton’s Laws.
- Identify real-world problems with solutions that require an understanding of the direction of energy by forces.
- Carry out an investigation showing that the more time in which a collision occurs will decrease the force acting on an object.
- Design constraints that minimize (reduce) the force on an object during a collision.

### Lesson Format

This lesson is designed to take approximately 4 days (or 250 minutes) and can be completed entirely online. The format can be either blended or synchronous/asynchronous. Students can interact with group work activities in Google slides & Padlet. Students will work on assignments including independent work annotating a safety article and a project-based assignment.

### Procedure

- Start here: Watch the Engage videos (approx. 10 minutes).
- Create an initial model, then compare & contrast with classmates (approx. 45 minutes).
- With your knowledge from the video, use the Pick a Pic related to what was shared on Day 1 (approx. 20 minutes).
- Annotate an article on Newton’s law as it relates to safety. (approx. 45 minutes).
- Engineer safety constraints for a collision (approx. 2 hours).
  - Decide on your project.
  - Design safety constraints for your project.
  - Conduct trials and create presentations.
- Present your presentation to the class (approx. 10 mins).
- Total estimated time: 4 hours 10 minutes.
