Marking Parachute Plan

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 1 Need some reference to what you are changing and what you are measuring

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.

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

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. 3 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)

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. 3 Mention an anomaly State a problem with your experiment State an improvement
