Sycamore Seed Experiment

Task- To make a model sycamore seed that can fly easily and stay in the air so in real life it would have the best chance to be carried away.

Aim

In this investigation I have been asked to find out how long it takes for a paper helicopter to fall 2 metres. After doing this I shall investigate other ways of changing the timing of its landing.

I shall do this by using a range of variables. These include of:

Ÿ Length of wings

Ÿ Number of tails

*I have chosen to use the variable of the number of paperclips being added to the tail of the paper helicopter that I shall make.

The gravitational force, which pulls the object downwards, is called the weight of the object.

Isaac Newton stated that there is a gravitational force of attraction between any two objects with mass, which depends on their masses, and the distance between them.

I think with this information I can easily say that by adding more and more paperclips on to the tail of the paper helicopter it will gain more weight, which will cause the gravitational force to pull it downwards rather than upwards as there is a bigger mass pulling it downwards.

 The diagram, which has been drawn above, has not been drawn to scale. Once I draw out the drawing of the paper helicopter on the A4 sheet of paper, carefully done using a ruler of course.

I am to cut along and fold along the lines as described: Where the dotted lines are shown this is where we are to fold along, and where the straight solid lines have been drawn in, we are to cut along them.

The cutting of course will be done with a pair of scissors. After they are cut out and folded along, some may find it better and more presentable if they are to be decorated and colour in their paper helicopters!

What else is involved in this investigation? Once all of the above has been done we are to set up our equipment out. Having set out the timer, paperclips, and paper helicopter in front of me, I am to make sure that I have drawn out a results table, which I will record the timings down in. (As shown in the results table.)

When dropping the paper helicopter out of my hands I am to make sure that I drop it at the same time that my friend is to say "GO", this is so that he can time it with accuracy.

As you can see, in the results tables above I have gathered all my timings into the table. Once I had placed all my timings in the table I was to work out the average of each set of timings. To do this I was to add up all of the sets of timings together and then divide it by 5 because that was the number of times I had done the experiment for each set.

Here are my workings out towards how I worked out the average for each set of results.

Workings out for Average(s)

When working out the, I firstly got all my timings for the specific set of results, added them together and divided them by 5, I divided it by 5 because this was the number of times I had timed it falling from the air to the ground. As shown below:

    Different surfaces have different friction level. A good example of this is rubber and plastic. (rubber tends to act with more friction on objects and plastic less) The data collected in the preliminary experiment helped us a lot in the final experiment. Without the trial experiment we would not have known how far to pull the elastic band back.
