Assembling components for an interactive book

Present the book to the user

This unit develops pupils' knowledge of mechanisms through levers and linkages. They will apply this knowledge by exploring mechanisms and incorporating them into an interactive book with a user-centred focus.

Levers and linkages: interactive books

a linkage that creates movement in the same direction using two pairs of levers

a linkage that uses short levers to push and pull three other levers in the same direction

A free moving point that connects two levers together.

A point that connects a lever to one place.
