Building Challenges

We watched the news clip on the collapsing bridge in Genoa, Italy. It  was amazing but very sad because we know lots of people got hurt or died.
Later in the day Mrs Dobbie set us a challenge to  build the highest, longest but strongest bridge with these cardboard bricks. The test was that our bridge had to be strong enough to withstand a gale force wind (Mrs Dobbie flapping a piece of cardboard). All our bridges passed!

Here's what we came up with.


















We thought ours looked like a crocodile!

Next we had to build the tallest building which could support a tennis ball.



















We really enjoyed these challenges. Mrs Dobbie said we could do some more another day!
