One robot. every week. Leads to many proud builders!👷♀️👷♂️
Every build wraps with a mini Robo-Jam: a competition or cooperation challenge where students put the robots they built in class to the test.
Swipe to meet this week's — the Ping Cannon. A stretched rubber band holds the energy, a trigger holds it back, and a ping pong ball goes flying. That's elastic energy and trigger mechanisms, learned with their hands instead of a worksheet.
