23rd June: The Naval Architect

What a busy afternoon Rainbird’s Year 2 class has had. We’ve been exploring floating and sinking with a little help from the youngest Billy Goats Gruff. We’ve designed, tested, taken measurements and redesigned to ensure that the goat made it safely across the river.

Now you’re back home, follow these steps for more floating and sinking fun:

1. Go into the kitchen and find some aluminium (tin) foil.
2. Build another boat and make it float in the sink.
3. Test out your boat by adding 1p coins to it – home many will it take before it sinks??
4. Try out a different boat design, change the shape of your foil and test it out again. Is it better or worse than your first design?
