On Thursday Y2H set to work on their challenge for Science Week. We had to make something to get the unidentified monster across the lake. Our investigation was to make a prototype to cross the lake. We discussed how we would do this and decide which one would be the best. How would we make it fair? We decided to keep the temperature of the water, container of water, depth of the water and the mass of the small load the same. Our variable we would change would be our boats. The children had a variety of resources to use including: foil, paper plates, paper towels, straws, plasticine and other bits and bobs that they could find around the classroom. The children worked in small groups to create their prototype. After testing all of our boats we discovered that most of them were able to cross the lake with the small load. How would we decide which one would be the best now? We then decided to test them again with a larger mass being dropped on them to see which boat would still be able to float. This time we only had one prototype left. Why? We looked at the design of this boat and saw it was waterproof, had higher sides and also had weight spread evenly within the boat. This then would definitely be our prototype to send to the lab.
Well done Y2H for completing your challenge.
