The Trebuchets Are Taking Shape

While the boys are working on the trebuchets we have a discussion about their construction and use. In the beginning the discussion focuses on the mechanism itself and how all of the parts work together. As I bring in other trebuchets that I have built we will discuss the difficulties in building extremely large trebuchets but the obvious benefits if the construction is successful. We also discuss their evolution and use in history. This will eventually culminate in some great activities with our completed trebuchets and a composition summarizing the history of trebuchets and our experience in building and firing them. We will also watch a Nova video in which two trebuchets are constructed using Medieval technology.
Here are a few pictures from the next stage of construction during which we added the second main support and the cross bolt which will eventually hold the throwing arm.
