In Science Club today, the children learnt about building strong structures. Lots of towers, such as the Eiffel Tower in Paris, are thick at the base and thinner at the top, to stop them toppling over.
The children were challenged to make a structure using only spaghetti and marshmallows. They learnt that one piece of spaghetti is not very strong, but if you use lots of pieces you can build a strong, tall tower.
Look at what they built.
