Scientific concept: When scientists do experiments where they have to change variables it is always important to have a control - the original that you can compare your new models to. If you don't have a control how will you know if the changes you make or for the better or actually making it slower or weaker? The other thing we looked at was only changing one thing at a time. If we change lots of things all together how will we know if they are all for the best?
To help support this concept of having a control we made a helicopter out of paper and labelled it as our control. Once we had our control made we could start changing things on the original to try and make it faster or slower. We looked at changing the blades, the weights with the paperclips and the length of the base to see how this changed the descension. After making many variables we had a cmpetition at the end to see who had made the fastest and slowest helicopters.
