My Prefect parachute Group 3 LEADER:WIDY Members:Haris (11) Tauseef(22) Farhan(7) Shafiq(16)

Objective To investigate the relation between parachute material and it’s falling speed

Design a fair test (1)Variable to be changed material of the parachute

Design a fair test (2) variable to be kept constant (Give at least two variables) √shape of the parachute √surface aRea of the parachute √length of string √layers of parachute √possition of string attachment points

Design a fair test (3)what to compare: √different shape √different viriable

Procedures Prepare plastic and following Prepare 8 strings same length Make holes 4 corners of each parachute Attach one string to each holes Tie the string Hang a taPe of each pparachut Drop the parachute from 6/f

Record s 1st 2st 3st 4st 5st 6st 7st 8st 9st 10st Material 3 2 4 Plastics Following

Find the average time of flight 1)=(1)±(2)±(3)±(4)±(5)±(6)±(7)±(8)±(9)±(10)÷10 =5.5

Discussion Give at least one possible error and corresponding improvement Mass Weight

Conclusion If the parachu Is longer in air, we need check he time how long

Finding of investigation List out the favorable viriable for a parachute √large surface area foil and plastic materials

Provide the final image of my perfect parachute

Give one difficulty that your group faced and how that was overcame during the investigation It’s was hard to make it fly became of the weight of plastic

Thank you Students and teachers
