11 Before Dropping the parachutes on Monday 10 minutes to 1. Make any changes. 2. Finish writing the experimental section include measurement of pawn (1.5 grams), measurement of parachute, and strings 3. Write design of your parachute in chart on back of worksheet. Example: Circle parachute with 16 cm diameter and 12 cm strings spaced 8 cm apart. Example: Square parachute and all sides 10 cm. The 14 cm strings are tied at each corner.

12 Parachute Drop Each team will drop their parachute twice and will be timed for each. Only 1 person from each group is allowed on the stairs to drop their parachute.
