Crack the Cam Lock Turn the dial to line up notches in three cams and open physics, mechanics, Technology the safe door. This models how cams are used in certain machines, cams, locks, kinds of locks. camshaft Crank the Engine Turn the handle and watch as pistons move up and down physics, mechanics, Physics forces & motion – inside cylinders to turn the engine's crankshaft below. machines, cams, (inertia, gravity, push, pull, Pistons and crankshafts interact within car engines to crankshaft, camshaft, acceleration) create movement in a car. speed, pistons, Technology engine, car Diff with a Difference Turn a handle and observe how separate and axles physics, mechanics, Physics forces & motion – turn car wheels at different speeds. Try holding one wheel machines, cams, (inertia, gravity, push, pull, still and keep turning the handle to observe how the crankshaft, camshaft, acceleration) second wheel responds. This shows how simple force, speed, wheels, car, Technology machines work together to steer a car. steering Play with Pulleys Connect cassettes containing different sized pulleys to pulleys, size ratio, effort, Physics forces & motion – broadcast a song, or make a cartoon pelican fly. The size speed (inertia, gravity, push, pull, and combination of pulleys determines how fast they (and acceleration) things that are attached) will spin. Technology Toying with Cams A toy caterpillar and toy dog have rods attached to parts physics, mechanics, Physics forces & motion – of their body, so different camshafts make them or machines, cams, (inertia, gravity, push, pull, ‘jump’ in different ways. This demonstrates how crankshaft, camshaft, acceleration) ‘wriggle’ different shaped cam discs can influence the pattern and force, speed Technology timing of how other things move.
