Before you begin

Teaching guide

What children will practise

Learn that a force is a push or a pull, tell pushing (moving something away from you) from pulling (moving it towards you), describe motion as fast, slow, stopped and by direction, learn that magnets attract iron but not every material, and meet six simple machines found in everyday life: lever, wheel and axle, pulley, inclined plane, wedge and screw.

What's in the worksheet

20 slides in an inventors' workshop with Fah, Mek and Bobo the robot - Slides 1-8, forces and motion: a force is a push or a pull (circle the pictures showing a force: pushing a trolley, pulling a rope, sleeping, reading); pushing (toy car, box, shopping trolley, door); pulling (wagon, drawer, rope, chair); sort eight pictures into push or pull; motion means changing position; fast, slow, stopped and moving; directions forwards, backwards, up, down, left and right - Slides 9-10, magnets: what they attract (paper clips, nails, screws) and what they do not (wood, plastic, glass, rubber, paper), with a hands-on sort into baskets - Slides 11-16, simple machines: an overview of six; the lever (effort, load, fulcrum; seesaw, bottle opener, crowbar, scissors); wheel and axle (bicycle, door knob, steering wheel); pulley (flagpole, well, curtains); inclined plane (loading ramp, slide); wedge and screw (knife, axe, screw, screw-top lid) - Slides 17-20: design an invention using two simple machines, match everyday objects to machines, a three-part review and a certificate - There are no answer slides

How to use it in class

Use in a Year 2-3 forces and simple machines unit over three or four lessons of about 30-40 minutes (slides 1-8, 9-10, 11-16, 17-20). - On slide 10 let children test a magnet on real classroom items such as clips, spoons, keys and coins and record the results; some real results differ from the slides, so try them yourself first - On slides 12 and 15 demonstrate with real things, such as a ruler over a pencil as a lever to lift a pencil case and pushing a toy car up a ramp versus lifting it straight up, then set the forces and motion worksheet and the magnets worksheet

Common sticking points

- Thinking magnets attract all metals, including aluminium and copper (slide 9 says only some metals) - Mixing up push and pull when the picture is unclear, such as a child dragging a box with a rope or a bulldozer pushing soil (slides 3 and 5) - Thinking simple machines must be big machinery, not realising scissors, door knobs and screw-top lids are simple machines - Thinking a still object such as a tree or a chair has no forces acting on it
