PAINT ROCKETS (Stationary Target)

Name______Pd____ PAINT ROCKETS (Stationary Target) 1) Please plot your three points of impact on the graph below. Number them in order. Example- 1st shot will be a dot with the number 1 next to it. Note the angle as well as the PSI next to each dot in parentheses. Please answer questions 2-15 in complete sentences on your own paper. 2) How did you change your 2nd second launching point compared to your 1st launching point? What impact did it have on the rocket’s flight? Is this what you expected? Why or why not? 3) How did you change your 3rd second launching point compared to your 2nd launching point? What impact did it have on the rocket’s flight? Is this what you expected? Why or why not?

4) If you were to restart this experiment, what would you do differently? Why?

5) How did your paint rockets do throughout the contest? Why do think that they were better or worse than the other team’s projectiles?

6) Did you reuse your single rocket or use multiple rockets?

7) Explain why it may be a good idea to reuse a rocket.

8) In what cases may it be okay to use a new rocket?

9) List at least 5 variables in this experiment.

10) Explain why a higher PSI may help the flight of the rocket.

11) Explain why a higher PSI may be a negative while conducting this investigation.

12) Why should you not have adjusted both PSI and angle in between launches? Why is adjusting one variable better than adjusting two variables? 13) What factors would you have to take into account if you were trying to hit a moving target? In at least one paragraph explain how your team your team would prepare.

14) How would a stop watch be helpful during this exercise (#13)?

15) How would a piece of string be helpful during this exercise (#13)?

*Please make sure that you have 3 rockets prepared for tomorrow’s activity
