The simple machines in this picture are a wheel and axle, pulley, and lever.

Wheel and axle is used for things like steering wheels on cars.

Pulleys are used to lift things.

Levers are used for things like sea saws for little kids.

So, we watched a video and some important things are loads, fulcrums, and effort ad where they belong.

Loads is between effort and fulcrum.

Effort is on the bottom side of the lever.

Fulcrum is the bottom of the lever, what it sits on.
