1. Lesson 2 Crash and Bash!
In this lesson students are introduced to a “crash box” that they can crash their cars into. Students will investigate what happens when cars crash into the box, as well as why different cars perform differently.

2. S4P3.c
Explain what happens to the speed or direction of an object when a greater force is applied.

3. During Class Presenting the Activity: 10 minutes
Reread EarthToy Design Letter
Model using the crash box on the track and testing a vehicle with it
Student Exploration: 30 minutes
Allow students time to test with the crash box in 3 trials(RM3)
Sharing and Interpreting: 10 minutes
Have students describe what they observed by writing in their science notebooks(RM 4)

4. What does the car you picked look like? How is it shaped?
Lesson #2
Brainstorming Questions
Engineering Design Experience
Build Knowledge
Ask your team members:
What does the car you picked look like?
How is it shaped?
What happened when the car hit the crash box?
Why do you think that happened?
How could you change what happened?
