Parachute Fun

Felix Baumgartner recently completed the highest free fall from space. Jumping was the easy part, the hard part was creating a parchute that would slow him down enough to get him to the ground safely.

Today you are a parachute designer. You will use plastic, scissors, twine, tape and a paperclip person!
Rules:
1. String can only by 30 cm in length
2. You must make two parachutes one a square with 10cm sides the other a square with 30cm sides
3. Attach your paperclip man to the parachute
4. Stand on a chair with a spotter
5. Let the parachute drop to the floor and time it with a stopwatch

What do you notice about the flight of each parachute? Which parachute stays airbourne longest?
