Experiment No.20 Make your own airplanes Materials:
You will need:
Some A4 paper Method: This is quite a simple experiment really. We made a number of the paper airplanes that can be found on Alex's Paper Airplane website and tested them in different ways to make them fly better. The photos here are some helicopters.
We also made a few very aerodynamic planes - built for speed - and others that were built to glide gracefully (!). To learn how
a plane flies, click on either of our earlier experiments -

Experiment:
To take
a look at flight in action - by making some paper airplanes.
We
made large ones and some very small ones to see which had the quickest
spin.
