As part of Science week we carried out the STEM 'Penny Boat' investigation. This is an investigation into buoyancy which involves designing and making a boat of tin foil, which will float on water. You then add 1penny coins to the boat to see how many it can hold until it sinks!
We split into groups of 4 or 5 and first discussed what we already know about materials which float and sink and how we could make the investigation a fair test.
Next, we designed the boats on paper and gave them a name, then made them out of tin foil. The designs yielded a variety of results; all of our boats floated unaided and managed to hold some coins and the winning boat was so sturdy that it held 139 pennies without taking on water or sinking, before we ran out of pennies and had to stop!!
We are going to repeat the investigation in the future to put our newly acquired knowledge about buoyancy to the test and use different materials.
Here is a link to the investigation if you would like to try it at home, let us know how you get on in the comments :)
