Yesterday we made contraptions which had to keep on moving for as long as possible - the one which goes for longest (after being started manually) and is most creative - wins. We are sending our best entry into the Science and Engineering week competition.
8 pupils opted to do this inside, with pendulums and spinning tops etc. The other 18 want to do theirs outdoors so on Monday we will test them outside. Ideas range from stick catapult contraptions to an aid pressure powered contraption using a foot pump, lego, plastic bottle - filled with some water so once ball is fired from bottle by air pressure it should flow down a stream of water down a slope outside...
Photos on Monday.
