2. OBJECTIVE
Investigate how length of string affect the falling time of the parachute

3. Instructions Cut out a large square from your plastic bag or material.
Cut a small whole near the edge of each side.
Attach 8 pieces of string of the same length to each of the holes.
Tie the pieces of string to the object you are using as a weight.
Use a chair or find a high spot to drop your parachute and test how well it worked ,remember that you want it to drop as slow as possible.

4. Variable to be changed
Length of string

5. Variable to be kept the same

Material of the parachute
Layer of parachute

6. Variable to be measured
The falling time

Average for long string =( )/3 = 0.8 min
Average for short string =( )/3 = 0.6 min

9. Conclusion
Parachute with longer string is better which falls slower.

10. Discussion Time is measured by different group mates.
