Bridge Building

Difficulty

Medium

Objective

To design and construct a bridge.

Materials

  • Glue gun
  • Popsicle sticks
  • Ruler
  • Items to measure bridge strength (LEGO bricks, books, coins, toys)

Method

1

Place 2 objects 30cm apart. These will hold either end of your bridge so pick something flat and sturdy eg. desk, chair, table

2

Looking at the distance that the bridge needs to cover and think about how you would build a bridge that will cover this distance using only popsicle sticks and glue

3

Build a bridge using the sticks and glue

4

Place the bridge between the 2 objects and see how strong it is – start small and gradually add more weight. Watch how the bridge reacts as you add more weight and notice where it breaks once it can’t withstand any more weight

5

Based off what you observed build another bridge and see if you can improve how much weight it can withstand
