Today year 5 used their knowledge of reversible changes to help others.
First they rescued a penguin who had been frozen into a hand of ice by the evil overlord "Mr Ice". The penguins were very grateful for being rescued and have not suffered any long lasting effects from their terrible ordeal.
Next they helped a gold panner whose camel had a strop meaning the bags of gold had fallen into the sand with the salt from his cooking kit. They have successfully separated the gold by sieving the mixture and have used their knowledge of materials to create a salt solution so that they could filter the sand out. Now they are waiting for the salty water to evaporate so that they can rescue the salt.
Well done year 5. You are heroes!
