Activity for today: Making a floating house!
Aim: Build a floating house that can hold the greatest number of marbles. Your budget is 5 units Each of the following things costs 1 unit: • 1 X cup (foam or plastic) OR 1 X balloon OR 1 X cardboard OR 1 X
brown paper back • 4 X straws OR 4 X paddle pop sticks OR 4 X rubber bands • 30cm sticky tape OR 30cm cling wrap OR 30cm aluminium foil

Would you live in this house? What materials did you use? What worked well? What didn’t?
Reflect:
But is this what happens in the real world?
Building materials You build with what available Resource limitation You couldn’t buy everything at the
stall Ideas With less money = innovation. You
all had different designs! Appropriate for the environment? None of you had a roof! Any other
problems you can think of? Time limit Shelter is one of the basic human
