Right now all 3 classes are building a mini trebuchets after making schematic drawing. The mini trebuchets will launch light objects such as bouncy balls, paper clips, marbles, paper balls and erasers. Kids have been bringing in materials such as pencils, wood, tape, hot glue guns, string and rubber bands.
On Thursday afternoon all the 5th grade classes went to mr. Vince's classroom. We all went there because, mr. Vince was showing everyone the Trebuchet simulator on his computer. There was two different simulator that we could choose from(the treb challenge and the trebuchet simulator). The Trebuchet simulator was a trebuchet on the computer, and you could customize the trebuchet to make it go farther. After we looked at the simulator we found out we were going to do it for homework. Then on friday, in morning meeting we talked about the simulator.
Ms. Johengen had us draw or make a marble machine. I find that we have done well making or drawing our marble machines. We have taken measurements of the distance the marble has to travel through the marble machine and the time it takes for the marble to travel from the start of the machine to the end of the machine; I feel that we should also measure the height of the machine and the width of the machine; it's possible that we could use this data on another project or for writing homework.
