To investigate a factor which affects the distance travelled by a projectile

Aim

My aim is to fire a margarine tub across the floor using an elastic band. I will identify the factors that affect how far my tub travels and then to study the effect of varying one of them.

Plan

After a lot of thought to which factor of the experiment I should change, I have decided to vary the weight in the margarine tub. I will accomplish this by starting my investigation with nothing in the tub, then add 100 g, do the experiment, record my results and then doing this again but with 200g.

Middle

I think that this is a good way of carrying out this investigation because I have not made it too complicating but at the same time I have chosen a skilful factor to change because it will show clearly which factors affect the distance travelled by a projectile.

How to make it fair

To make this investigation fair I will use the same margarine tub each time. I will also start each time in exactly the same place. The person actually doing the experiment will not change and I will pull

Conclusion

My prediction

I predict that if there is more weight in the margarine tub it will not travel as far, and that the first time I do the investigation when there will be nothing in the tub it will go the furthest. I think this will happen because there will be a greater force acting against the tub as it will be much heavier.
