7. 15 Minute Challenge – Naked Egg Drop
Using given materials, construct a catching device for a naked egg dropped from 8 ft (hand against ceiling outside)
Everything must remain in container during & after drop
You can build higher than the edges, but 1st rule still applies
DO NOT ALTER FOIL CONTAINERS IN ANY WAY!!!!
Alterable Supplies: 2 pieces bread, 1 toilet paper roll, 1 cup flour (baggie can be used as well), 1 tape dispenser, 4 paper plates
Unlimited supplies: computer paper & water
Contraption should be able to stand on its own

8. Naked Egg Drop Challenge
Prepare container
Prepare person who will drop from 8 feet high
DO NOT START UNTIL I AM THERE TO WITNESS!

9. Naked Egg Drop Challenge (TPS)
Notebook Reflection
Date: 1/15 or 1/16
Were you successful or unsuccessful? What traits do you think help prevent the egg from breaking?

10. Booklet Panel 3 (top): Impulse-Momentum Theorem
Write small, try to copy my spacing

11. Break
5 Minutes

12. Practice on Momentum & Impulse
Write work and answer in your notebook.
You can refer to page 1 of the booklet for momentum
You can refer to page 3 of the booklet for impulse

13. Practice on Momentum
What is the equation for momentum?
p = m x v

14. Practice on Momentum
A baseball has a mass of 0.2 kg and is thrown at a velocity of 17 m/s. What is its momentum? Show calculations.
2.55 (kg*m)/s

15. Practice on Momentum Discuss with a neighbor:
If someone says that an object’s momentum is to the left, which way is its velocity?
Its mass?
Make sure to record the answer in your notebook!
The object’s velocity is also to the left. The mass is a trick question, it has no direction.

16. Practice on Momentum
Discuss with a neighbor: Which of the following has more momentum? Justify your answer!
A heavy truck at rest
A moving skateboard
Make sure to record the answer in your notebook!
A heavy truck at rest has a velocity of 0 m/s, so regardless of its mass, it would have a momentum of 0 (kg*m)/s. The skateboard has a mass and velocity, which would always multiply to a greater number than the truck.

17. Practice on Momentum
You throw a chicken at your best friend b/c you think this is the best way to express your love. You know that the chicken has a momentum of 15 (kg*m)/s and has a mass of 3 kg. What is the chicken’s velocity? Show your work.

18. Practice on Impulse
Discuss with a neighbor: 2 identical cars are driving the same speed. The first car stops in 2 seconds, the other stops in 4 seconds. Which one will experience more force and why? (Doesn’t require a calculation)
Make sure to record the answer in your notebook!
Since they have the same mass and same change in velocity, they have the same change in momentum. But the first car has a shorter time to impact, so it experiences a greater force.

19. Practice on Impulse
Discuss with a neighbor: Why is a good idea to have your hand stretched forward when you are getting ready to catch a baseball?
Make sure to record the answer in your notebook!
