Part 1 – Tumble glider
Explanation of Bernoulli’s Principle
When air goes above the wing it moves faster creating a low pressure and the opposite happens under the wing

1. Draw a path of the trajectory of your rocket
2. Which force is acting on the rocket at the moment of launch? (use arrows to indicate direction)
Negative and positive pressure there is positive pressure putting out of the rocket and negative pressure
3. As the rocket was half-way up, which force(s) is/are acting on the rocket? (use arrows)
4. As the rocket begins to veer into another direction, which force is acting on the rocket? Explain why this is happening.
5. Did some rockets work better than others? How does the shape of the nose and fin affect the trajectory of the rocket? Explain in terms of the four forces that act on a rocket ship.
The more pointy the nose is the less drag is and the fins help with keeping it straight
1. How did the height you estimated your rocket would reach compare with the actual
2. What do you think might have caused any differences in the height you achieved?
The weight and design of it
3. Did your rocket launch straight up? If not, why do you think it veered off course?
It had more drag on one side turning the rocket
4. Do you think that this activity was more rewarding to do alone? Would you have preferred to do it in groups? Why or why not?
I liked doing it alone because you can do whatever you want without people getting in your way.
5. Did you adjust your model rocket at all? How? Do you think this helped or hindered
6. How do you think the rocket would have behaved differently if it were launched in a
It would have gone forever
7. What safety measures do you think engineers consider when launching a real rocket? Consider the location of most launch sites as part of your answer.
Launching it over water because it’s safer to land there and the boosters aren’t going to explode when they hit the ground
8. When engineers are designing a rocket which will carry people in addition to cargo, how
do you think the rocket will change in terms of structural design, functionality, and
It will have more human-friendly spots and have more or less thrust/ fuel
9. Do you think rocket designs will change a great deal over the next ten years? How?
Yes, I do because how much technology is improving they will have more efficient ways of getting to space.
10. What tradeoffs do engineers have to make when considering the space/weight of fuel
vs. the weight of cargo?
They might not be able to carry as much cargo.
