Natural Science home work

As your home work, Super heroes, look at each of these instruments and try to find in what part of them we have the load, the fulcrum and the effort we do to use them! For example, in the second picture (nutcracker) we apply our effort on the handles, circle 1; and the load is the nut (almonds, nuts...) we put to open, circle 2; the circle 3 is the fulcrum.
