Building Bridges at Currie Primary School

On the 29th of April, all of the P7’s got the chance to design and build bridges with Edinburgh College. We got put into small groups and then we learnt about the different types of bridges. We went on a TEAMS call to learn about how we could make our bridges stronger using tension and compression.

We got a pack of items including card, paper, string, split pins, straws, elastic bands and a limited amount of tape that we could use to make our bridges . We got about 2 and a half hours to plan and build our bridges.

Then we tested our first bridge and it held 2.2kg! We went on another TEAMS call and got to show some of the bridges to Edinburgh College and the other classes. The winning bridge in our class held an amazing amount of 4.5kg!

This was a fun experience and we all thank Edinburgh college for giving us this opportunity!

On the 29th of April P7b did a STEM building challenge with Edinburgh College . The challenge was to make a bridge which holds the most weight. 

We had to make them out of paper strips, paper straws, a piece of string, some cellotape, 2 pieces of card, 2 pieces of paper and 2 elastic bands.

We went on a teams call with 4 other classes and people from Edinburgh college. They taught us all how tension and compression works and what designs work best they also told us how to use the resources we had to make our bridges. Then they gave us about 2 hours to make them.

We made our bridges by using some of the techniques like tying paper straws together using string and strengthening the base by using card paper and straws then we tested them with weights and then went on a call and showed the other classes and they showed us theirs.

The winning team got 4500g, 2nd got 2900g and 3rd (my team)got 2200g.

We had lots of fun!

Fia, P7B
