We are going to try and take pat in this years junior saltire competition, which is to design a wave powered electricity generator.  Here are some commercial examples of wave power generation to start off with.
Limpet Animation



Here is a diagram of the Islay LIMPET wave powered generato.

Wave power great video for ideas.

Port Ellen Science club kicked off this term with a building session using Knex, Lego and Quadro to build a vehicle of some type. Great designs, and an opportunity to see how different materials require different approaches.
Next a collective decision was made to try the Crest science activities from Einsteins Birthday Party Pack, a trial set from the British Science Association. These were great, and involved lots of balloon based experiments, Ewan’s group managed to put a pin in a balloon without bursting it and Anwen was able to use a balloon to move water without touching it.
Next week groups worked in teams to make a balloon powered rocket to carry an item across the room. There were some difficulties with friction and direction though!
Finally we had a science quiz to test the teams knowledge of all aspects of science, the chemists were the winners by a narrow margin.
