Secondary Inquiry Questions

Q: Can we replicate the safety devices in vehicles to balance forces?

...and protect an egg from a four meter drop?

Gr.9 Physicists have been investigating how forces and Newton's Laws apply to vehicles.

Throughout the unit the students have considered:
Why people without seat belts will continue moving forward after a crash?
How a crumple zone at the front of the car absorbs the impact of a crash?
Why airbags have become a very common feature of modern cars?

This culminated in an Egg Drop Challenge.

Students had limited equipment including two balloons, two chopsticks and 20cm of tape to make a safety device for their egg.

Some eggs survived, but most eggs didn't.

Students were then able to demonstrate their learning, evaluate their product and make suggestions for improvements.

Our future scientists and designers at work!
