P5/6 thoroughly enjoyed completing their Titanic inspired STEM challenge, as part of our Titanic IDL topic. After learning about buoyancy and factors which can impact upon floating and sinking, we designed and constructed our own lifeboats. We then tested our lifeboats and counted how many ‘passengers’ (marbles) they could safely hold. During our tests, we found that the safest lifeboats had the largest surface areas, with the most efficient lifeboat carrying 110 passengers to safety.
