Hi this is Regan and Simran and today we are going to tell you about our Maths investigation.
The whole of year 6 had earned a trip to Light Water Valley, and today we got a letter asking if we could do an experiment to find out what could be the safest shape for a roller coaster. We made 3D shapes from spaghetti and marshmallows, we needed something straight (spaghetti) and we needed something to hold the roller coaster together (marshmallows).
We had 3 shapes to see which one was more stable, 3 shapes were a squared roller coaster, a rectangular roller coaster, and a triangular roller coaster. But there was a twist, we could only use 15 cm for the base and the height could be any size. On the other hand, you had to make the roller coaster stand on a flat surface and if it fell over then you would have to tell the teacher why it didn’t work and then you go onto another shape. Well anyway, are you wanting to know which shape was the most stable? It was ……… a TRIANGLE (a triangle based pyramid).
Simran and Regan OUT!!!
