Marking Parachute Plan

AimTo investigate the effect of the surface

area of the parachute on how long it takes to drop/ The amount of time it takes to drop


Need some reference to what you are changing and

what you are measuring1

HypothesisI think as the size of the canopy increases

the amount of time it takes will increase. This is because for the larger parachute the effect of air resistance will be higher and will therefore increase the amount of time it takes for the parachute to drop.


State what you think and a justification why and any relevant

Science you can include3

ApparatusPlastic Bag StringWeight Sticky tapeRuler ScissorsStop clock(Height to drop from)


Most apparatus included

All apparatus included 2

Diagram


Diagram (Pencil and ruler used), with labels. And any

information. How to make

parachute

Method1. Collect all equipment 2. Cut bin bag into squares of different sizes

(x=20cm -70cm increasing 10cm each time, 6 in total)

3. Attach string, of length 30cm to each of the 4 corners (as shown in the diagram)

4. Attach the weight to the 20 by 20cm parachute.5. Raise the parachute to the height as shown in

the diagram 6. Record in a table the amount of takes the

parachute to fall the height shown in the diagram once released

7. Repeat steps 4- 6 with each of the different size parachutes. Make sure to repeat each size parachute 3 times

8. Ensure the height being dropped and the weight remains constant

Marking Parachute PlanNeeds to be bullet pointed/ numbered

Need to clearly say the different size of

canopy (this can be in apparatus)

Instructions need to be clear and make

sense

Any control variables being stated

SafetySensible behaviour in a Science lab, bags put away and stools

tucked under as this may be a tripping hazard and scissors are being used.

Be careful when dropping from a high height as may slip over and this could be dangerous.

Make sure not to stand directly under the parachute when being dropped as may fall on head, also need to make sure keeping an eye when parachute is dropping as its course may change by the wind and this would also effect the dropping time


State what the potential hazard is and why it could be dangerous. At least two sensible hazards

stated and explained

ConclusionMy results agree with my hypothesis as the

size of the canopy increases the time it takes to drop increases. This is seen as a positive correlation on the graph. Most points lie on or near the line of best fit showing reliable results.


Mention your hypothesis Mention the graph

Mention the scatter of your points(If you have calculated a value discuss how close you are

to the expected value- how accurate the results are)

EvaluationI think my experiment went well as I

managed to get a good set of results. However their were some anomalies (Quote the result ) I think the experiment could be improved by carrying out the experiment indoors as this would reduce the effect of wind on the experiment as this would effect the parachutes flight.


Mention an anomaly State a problem with your experiment

State an improvement 3
