2. Objective
Investigate now how length of strings affect the falling time of parachute
This is the question that your experiment answers

3. Design a fair test Variable to be changed:
Length of strings
Variables to be kept constant:
Material of parachute
Weight of the load
Shape of parachute
What to compare:
Falling time

4. Variables Controlled variables
These are kept the same throughout your experiments
Independent variable
The one variable you purposely change and test
Dependent variable
The measure of change observed because of independent variable
Decide how you will measure the change

6. Longer string will be better and faster.
Conclusion
Longer string will be better and faster.
Establish hypothesis before you begin the experiment. This should be your best educated guess based on your research.
