Here is a song I created to help my 6th grade students study. I hope you enjoy. These are types of simple machines Levers pivot on fulcrum Three classes made based on locations Of fulcrum, load, input force Slanted- a ramp helps you roll, makes an inclined plane Push it with ease, input is down But the force is spread out far Easier The work that machines have made The work that machines have made Easier The work that machines have made Easier The work that machines have made Have a knife the wedge cutting deep, distance of force increased Spiral plane, a screw will rotate, small force equals large output Doorknobs, axel and wheel, can you see it turn? Bigger is wheel, rotating axel Making output force much larger Easier The work that machines have made Easier The work that machines have made A window blind, pulling a chord, pulleys-a rope and wheel The load is placed to rope at one end, force applied-other side Two types-fixed don't move, direction of force is changed Movable pulley, moves up and down Block and tackle combines for force Easier The work that machines have made The work that machines have made Easier The work that machines have made Easier The work that machines have made
