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

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)

Bernies principle

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




Principles of Flight Part 3: Water bottle rockets

  1. What have you learned about the history of rockets and space travel?

That the USSR was the first country to have a satellite orbiting the earth

2. Now that you know about the basic parts of a rocket and what they do, write about each part and its importance in your own words. What will be different on your water rocket than on a “real” rocket and why?

It’s not going to use fuel,  it is going to all stay together, Hight, weight

3. Write a little on the blog about how to find the Center of Pressure and the Center of Gravity on your rocket and why they are important.

You can find the center of gravity by trying to balance it on your finger, tie a string to the center of the rocket to see where the center of pressure is. The center of gravity needs to be somewhat centred to make the rocket balanced.

4. Based on what you have learned about rocket design (nose cone & fins) describe what your rocket will look like and why you chose that design on the blog.

 I will have a pain bottle with a nose cone for less air resistance with 3 fins for stability

Principles of Flight Part 3: 2L Water Bottle Rocket Reflection

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

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
your results?


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

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.
