Driving Question Redo:

I am going to change my driving question to the one you suggested: Which simple machine is most benefical to human beings? For the task I was going to have them be separated into 6 groups. Each group will create a simple machine. Each simple machine will be used only once. The CSOs, that I was trying to find, did not have any about simple machines. So I have selected these 2: SC.O.4.3.2 - create models as representations of real things. SC.O.4.3.7 - use an appropriate engineering design to solve a problem or complete a task. Are those 2 CSOs fit the task?
