Simple machines help you in life by doing the work for you and helping you get something open or someplace else in an easier way. We have them because it just helps us with things that human can’t do by themselves.

1. My first object is a staircase.
2. The staircase is an inclined plane because it goes up at an angle.
3. We need this because it helps us go up levels on a building and other things.

1. My second object is a handle on a locker.
2. The locker handle would be a lever because as we pull it up it opens the locker.
3. We need this because without it we wouldn’t be able to get doors or other objects open.

1. My third object is a elevator.
2. The elevtor would be a pully because for the elavator to go up or down it has to be pulled by chains on the very top of the elavator.
3. We need this because people that have injeries and can't walk upstair can jsut us the elevator to get form one level to the other.
