2L Water Bottle Rocket

1. How did the height you estimated your rocket would reach compare with the actual
estimated height?

The rocket didn’t as nearly as high as I thought it would.
2. What do you think might have caused any differences in the height you achieved?

My rocket didn’t go as high because it launched early before the rocket was ready and didn’t have enough air pressure.
3. Did your rocket launch straight up? If not, why do you think it veered off course?

My rocket veered of to the right. I think it is because of the bad launch but i’m not 100% sure.
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 the activity alone and probably would have found it rewarding if my rocket was successful.
5. Did you adjust your model rocket at all? How? Do you think this helped or hindered
your results?

I had to alter the design for the top of the rocket but I didn’t think that ended up effecting the launch of the rocket because there wasn’t enough time for the parachute to deploy.

6. How do you think the rocket would have behaved differently if it were launched in a
weightless atmosphere?

The rocket would have continued to have gone up if it was a weightless atmosphere.
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.

Engineers need to make sure it’s an isolated area with no buildings or trees in the area for the blast
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

They need to make sure there is a fuselage in the rocket and living area
9. Do you think rocket designs will change a great deal over the next ten years? How?

I think they will relatively look the same because rockets have looked
10. What tradeoffs do engineers have to make when considering the space/weight of fuel
vs. the weight of cargo?

They need to make sure there is enough fuel to counteract the weight of the cargo.
