Many buildings around the world are made of bricks. Here you see a collection of different kinds.
- Get hold of one or more bricks to use
- Make a brick shape with the materials you have (you could make it solid but you don't have to).
Compare the weight or length or volume of the different bricks you and your friends have.
Now suppose you have two bricks the same.
What is the weight or length or volume of the two together?
What about if you have 3, 4, 5, 6, 7 or 8 bricks?
What can you find out?
