On Friday we were engineering a bridge made out of play do and finding the weak and strong parts. We learnt about civil engineers and how they design bridges. We also read a book about different types of bridges before we designed and created our own.

This is what you need to build a bridge
  • tooth picks
  • a Lego car {To test if your car can hold the balance}
  • play dough {to hold the tooth picks together}
We used square shapes to make our first bridge but it was not strong and it could not hold a lego car.

Then we use triangle shapes in our bridge and it was so so so strong! It held the car

What is the strongest shape?
  • circle
  • triangle
  • square
