Now, I know we should have used A4 paper in the experiment, however, all I had to hand at the time was some thin A4 card - obviously, this did have an effect on the outcome of our experiments which I'll go into later.
The point of the task was to see which shaped structure would hold the greatest weight (in the form of a bottle of water) before failing.
Ethan firstly thought of various shapes, then set to making them. He was allowed to use some tape, but only to hold together the shape (it didn't in any way support or add strength to the structure).
He made a circular tube, a square tube, and a triangular tube, all of which were bridged over a 21cm gap.
The bottle could hold a maximum of 1 litre of water.
We had some initial success, and by this I mean the structure failed once a certain amount of water was added to the bottle, however we soon realised that thin card is far too strong for this experiment to be a true success.
With the square and triangular tube..we ran out of water before either structure was showing signs of failing. Therefore we abandoned the experiment, thinking it best to wait until tomorrow when we could get some normal paper. Ethan however agreed that it would be interesting to rig it all up again and continue with the two experiments side by side to see exactly how much stronger the thin card is, compared with just paper - whilst at the same time, finding out which structure is best suited as a bridge, and can hold the most weight.
So, somehow, we have managed to create a multiple experiment, which not only includes physics, but also maths.
It is exactly this element of Home Education which we love. The freedom to just let things take us where they naturally progress to, and enjoy the ride. :)
