Since we've finished our mechanical engineering story, first graders are not seeing exactly how machines move and as a result, make work easier. This week and next week we are focusing on the following things:
1. The purpose of the machine (Why it was created?)
2. The action needed to get the machine moving (Push/Pull)
3. The resulting action of the initial force (How did the parts move?)
4. The advantages (+) and disadvantages of the machines.
