Learn how Gears can easily reduce or
increase speed, change force. or transfer motion from one position to
another. Discover how Worm Drives are used to greatly reduce rotational
speed and how screws can convert rotational motion to linear, while
greatly increasing force. Build 12 working models such as an
experimental crane, a gearbox, a carousel, a helicopter, a screw press
and a crane with a rotating arm. You can find easy-to-follow building
instructions for all models either online or in the booklet included.
The booklet provides detailed explanations of the different scientific
principles applied and incorporates innovative experimental activities
for hands-on learning. A Quiz section is also available to challenge
your newly acquired knowledge! Conduct thorough experiments and
- how the handle's position affects force and speed;
- how the crank's position affects force and speed;
- how to calculate the mechanical advantage of a screw;
- what a worm drive is and how to use a ratchet mechanism.
