Teaching mechanical principles to a whole class just got an infusion of fun! The Cam Bird Paper Models features a cute bird pecking the ground when the crank is turned – a great tool to help students understand how cams turn rotary motion into reciprocating motion. The models are die-cut paper, so just pop them out, fold, glue, and assemble. Plus, the models can be colored and personalized by the students.

Comes with 15 paper models. Recommended for ages 11 and up. Requires white glue, sold separately.
