At school we did the trebuchet. First we had to put weights in the budget then put the nail through the wood. After that we pulled the string and where it landed we had to measure it.
My observations were when the string got pulled, the bucket went down so the tennis ball could go around and get let off. I think this was because the 4 weights We're so heavy that when you pull the string it goes straight down letting the ball off.
My wonderings were why could they not build it easier, like load it up then pull it back letting it go but then it would be copying the slingshot.
My learning is relational because I can connect my ideas and explain how it works to other people. My inferences are multi-structural because I can write my ideas and show how it works.
