BUILDING A BRIDGE
OUR STEM project this term is to make a bridge out of ice cream sticks.
We are in groups of three and have to make a strong bridge at least 600mm long.
We have to plan on paper first, drawing up an idea and then we started making bits of the bridge. Each person had a role to play in the groups – who is making the sides, the bottom and the top.
Then we started building the bridge by gluing the sticks together, which takes a very long time and lots of concentration.
In our group we made the bottom in DAT ( Design and Technology) in term two and have used it in our design in term four.
Our design is very strong and should win the competition. Now we are starting on the sides.
Most other groups are up to the same stage as us and we aim to be finished in another three weeks ready for the competition in week eight.
At the end we are going to put weights on the bridges to see which one is the strongest and the winner will get a prize.
We have learnt that using triangles when building the bridge makes it a lot stronger than using no triangles. — By Teagan and Caitlen
