STEM Challenge Day
On Thursday four girls from Year 5 went to Invicta for a Science, Technology, Engineering and Maths (STEM) challenge day. First we tested how many polystyrene cups could hold our weight. One cup could hold 10kg so we worked out that 7 cups would hold our weight. Next we designed a tin foil boat to hold marbles and in ours we fitted 20 marbles in before it sunk. Then we made a bobsleigh. We used a plastic slab, duck tape, ties, wires and a tube. We launched it using a special pump.
After that, we had 10 minutes to make a catapult to fire blu tack. We loved our design! In every activity we earned points and these points converted to money. We used the money to buy things to make a parachute. The parachute had to hold an egg! There were three tasks: design, accuracy and the slowest. Our egg didn't crack! At the end of the day we made rockets and a rocket got stuck to the ceiling! It was an amazing day at Invicta and we had a great time.
