Objective Investigate now how length of strings affect the falling time of parachute This is the question that your experiment answers
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
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
1st 2nd 3rd 5.5 6.0 5.8 3.6 3.9 3.8 Records Long (3cm): Short (5cm): Length of strings 1st 2nd 3rd Long (3cm): 5.5 6.0 5.8 Short (5cm): 3.6 3.9 3.8
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.
