In class today we did science. We are trying to figure out how to make a humming noise and then stop it then end it with a ding. A hum dinger is a system that we are trying to figure out how to do it. Mr.Scattergood  has one in a bag but we can't see it we are supposed to build it with a lot of things. So far we are almost there just add a little more work to it and its done.

I think this is a good science experiment.
