  1. Marking Parachute Plan

  2. Marking Parachute Plan Aim To 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 measuring 1

  3. Marking Parachute Plan Hypothesis I 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 include 3

  4. Marking Parachute Plan Apparatus Plastic Bag String Weight Sticky tape Ruler Scissors Stop clock (Height to drop from) Most apparatus included All apparatus included 2

  5. Marking Parachute Plan Diagram Diagram (Pencil and ruler used), with labels. And any information. How to make parachute 4

  6. Marking Parachute Plan Needs 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 Method • Collect all equipment • Cut bin bag into squares of different sizes (x=20cm -70cm increasing 10cm each time, 6 in total) • Attach string, of length 30cm to each of the 4 corners (as shown in the diagram) • Attach the weight to the 20 by 20cm parachute. • Raise the parachute to the height as shown in the diagram • Record in a table the amount of takes the parachute to fall the height shown in the diagram once released • Repeat steps 4- 6 with each of the different size parachutes. Make sure to repeat each size parachute 3 times • Ensure the height being dropped and the weight remains constant 5

  7. Marking Parachute Plan Safety Sensible 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 2

  8. Marking Parachute Plan Results 3 All Heading and UNITS included Any anomalous results highlighted and not included in average. Overall presentation (ruler and pencil used)

  9. Marking Parachute Plan Graph showing the amount of time it takes different sized canopied to drop Title Label and Units Independent on x axis (what you changed) Dependant on y axis (what you measured) Axis and Sensible Scale Points plotted accurately Line of best fit drawn Graph 8 7 6 5 4 3 2 1 0 × × Time for canopy to drop / Sec × × × × × 5000 4500 4000 3500 3000 2500 2000 1500 1000 500 0 6 Surface area of canopy/ cm²

  10. Marking Parachute Plan Conclusion My 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) 3

  11. Marking Parachute Plan Evaluation I 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

  12. Marking Parachute Plan Total 32 Try and think about the key points and the process of writing a plan

  13. Your turn I want a PERFECT PLAN … How … Effects stopping distance
