Learning sequence: Learn about gears

az_legoclass

This suggested sequence of activities begins with an exploration of simple hand-powered gear trains. The second and third activities use gears to decrease the rotational speed of motor-powered music boxes and fans. The last three activities incorporate gears into cars so that they can win a “snail race” or climb steep ramps. This learning sequence […]

Look Ma, No USB! Untethering the WeDo

This WeDo car has an AA battery pack for power and an infrared receiver.

To keep the WeDo simple and easy to use for younger children, the WeDo doesn’t have an intelligent brick in its building materials. No intelligent brick, so no programming and no power. The USB hub is there to provide both from the computer. But, wouldn’t it be great to be able to untether some WeDo […]
