We will be doing a unit on simple machines. I would like to put some items in a sensory bin for the children to explore with. These are 4 year olds. I have sand as a filler, dump trucks, trucks with cranes/pulleys, etc. I am drawing a blank for other stuff! Can anyone give me some ideas to put in the bin?
