Discover Primary Science Award 3

Room 10 completed their final experiment this week. This week we became engineers and explored how bridges are built.

Experiment 3: How bridges are built. 

Equipment:

• Lego
• Cardboard
• Spaghetti
• Blue Tac
• Popsicle Sticks
• iPad

Activity:

1. Using the iPad we explored different types of bridges and what makes bridges strong.
2. We read a book telling us interesting facts about bridges.
3. We found out that a triangle is the strongest shape and this is what engineers use when building bridges.
4. We split into 4 groups (Lego, Lego & cardboard, spaghetti & Blue Tac and popsicle sticks & Blue Tac) and attempted to build strong bridges.

Results:

Some of our bridges were too weak and could not support any weight. Some of our bridges were really strong. 

Conclusions:

• Bridges that were built with triangles and supports were the strongest type of bridge.
