1. Science Project Learning “The Perfect Parachute”
2D1,Group 6
Members : Aaron,Ismat,
Isaiah,Zoie and
Yasmine

2. Objectives of these experiments:
Our main objective is to figure out which variables are the most important when making ‘THE PERFECT PARACHUTE’.
To investigate how one variable can affect the flight of a parachute.

3. Variables:
Size of the parachute
Shape of the parachute

4. Materials used: Plastic sheets (for the surface area)
Strings (for attachments)
Timer (for timing the whole experiment)
Tape (used as the load)

5. Size The 3Cs Table: Variable to be changed:
Variables to kept constant:
What to compare:
Size
Weight of load
Time taken for the parachute to reach the ground.
Length of strings
Material of parachute

6. Experiment 1
Size
Obj: To know which size allows the parachute to fall slower or faster?

7. Procedures: EXPERIMENT TIME:
Prepare plastic sheets of area 30×30 cm & 20×20 cm
8 strings of the length 20 cm
Make one hole one each corner & attach 1 string to each hole.
Attach the strings to a load.
EXPERIMENT TIME:
Drop the parachute and start the timer at the same time.
Stop the timer when the parachute touches the floor.
Do at least 3 tests to justify the final result.

8. 30×30 cm
20×20 cm

9. Results: 30×30 cm 20×20 cm 1st TRIAL: 2nd TRIAL: 3rd TRIAL: Average:

10. Conclusion:
The bigger the size,the bigger the surface area.More air is tucked under the parachute allowing the air to carry the parachute,allowing the parachute to fall slower.

11. Experiment 2
Shape
Obj: To know what type of shape allows the parachute to fall slower or faster?

12. Shape The 3Cs Table: Variable to be changed:
Variables to kept constant:
What to compare:
Shape
Weight of load
Time taken for the parachute to reach the ground.
Length of strings
Material of parachute

13. Procedures: EXPERIMENT TIME:
Prepare plastic sheets of different shapes
Area must be 900 cm
Square (30×30 cm) & Rectangle (15×60 cm)
8 strings of the length 20 cm
EXPERIMENT TIME:
Drop the parachute and start the timer at the same time.
Stop the timer when the parachute touches the floor.
Do at least 3 tests to justify the final result.

14. Square
Rectangle
15×60 cm
30×30 cm

15. Results: 30×30 cm 15×60 cm 1st TRIAL: 2nd TRIAL: 3rd TRIAL: Average:
Square
Rectangle
30×30 cm
15×60 cm
1st TRIAL:
11.93s
9.18s
2nd TRIAL:
10.28s
10.03s
3rd TRIAL:
11.15s
9.17s
Average:
11.12s
9.55s

16. Error:
Improvement:
Getting the exact same time of letting go of the parachute and timing the experiment.
Do not have a countdown for letting go of the parachute, it only delays the person who is timing the experiment.

17. Conclusion:
The bigger the surface area of the parachute, the more air it has under the parachute which makes the parachute travel at a slower speed.
If the parachute has a rectangular shape, then the falling speed of the parachute is faster.

18. Overall Conclusion: A PERFECT PARACHUTE must have:
A big parachute size or a large surface area for more air flow to reduce the falling speed of the parachute.
An equal shape for better balance.
(For example:a square,circle or even a triangle)

19. Difficulties our group faced and how it was overcomed:
The tangled strings
It was hard to find everyone in the group because of unexpected schedules.
How we overcame these problems:
We spent some time untangling the strings.
We started a groupchat to plan ahead of time.
