I demonstrate the movement one can get from levers, sliders, fixed and loose pivots. Each pupil then builds a figure of a person where the head and the arms move as a button is slid up and down. The legs are loosely pivoted. It fits in with Science Ourselves, parts of the body, as they make arms, head, hands etc. After I finish the activity the students can then decorate their person with junk modelling bits & pieces.
