Because of the coronavirus in China, we had to continue our projects at home, so here we are, making and dropping parachutes, in a house. The purpose of the Pangaroos is to deliver a portable charger in a box safely to the ground and we plan to do that by designing a parachute. Our research  question is how holes in the parachute will affect the accuracy and drag of the package.

This is the procedure we plan to use to collect data for our drops:

  1. Place items into box and seal box with tape  
  2. Clear area underneath dropping area  
  3. Set up ladder
  4. Prop up iPhone on iPhone holder 
  5. Press record button on iPhone
  6. Climb up ladder with package
  7. Release the package
  8. Get off the ladder
  9. Stop recording by pressing record button again
  10. Cut the recording so only the falling package part remains
  11. Send video to computer
  12. Upload video into logger pro
  13. Record data with logger pro
  14. Repeat steps 1-13 5 times

And this is the data table for collecting data:

String: 45cm
Parachute Diameter: 65cm
I made the Diameter smaller and the cotton string longer since that it will drag the parachute in if the parachute is bigger and the string is shorter.
