This term, we have been exploring structures, focusing on different types of bridges. We started by learning about beam bridges, arch bridges, and the clever truss bridges, which use triangular shapes to distribute weight. We linked this to our History topic of Anglo-Saxons and Vikings, thinking about how we could reconstruct a strong bridge for them. One example we looked at was the Ravning Bridge in Denmark, built around 980 by Viking King Harald Bluetooth (yes, that was his real name!). Although its exact purpose is unknown, it may have helped troops or traders cross the river valley quickly.
To put our learning into practice, we designed and made our own bridges using masking tape and spaghetti! We had to work in groups, apply our knowledge of strong structures, and test how much weight our bridges could hold. Some of our designs were impressively sturdy!
This week, we’ve moved on to creating bridges from wood. We carefully measured and marked our pieces, learned how to safely use a saw, and held the wood steady in a vice as we took turns cutting. Some of us have even started using hot glue guns to assemble our bridges.
Next week, we’ll finish our wooden bridges and carry out an evaluation to see which designs worked best and why.
If you were building a bridge for Viking warriors today, what design would you choose and why?
