Parents, Educators & Engineers

Dream It. Build It. Teach It!

Get kids excited about engineering.

Now that's some set of pipes!

Beatriz is a high school student in Emeryville, California with two passions: music and bicycles. Building bicycles, to be exact. (This girl knows her way around a blow torch.)

Beatriz loves to create and wants to build something unique that combines her two passions--sounds like just the challenge for our favorite pair of engineers. In Musical Bike, Judy and Adam help Beatriz design and build a pedal-powered pipe organ.

You can use Musical Bike as a launching point to teach your kids the science and engineering of sound. Watch the episode and read on for more!



Ready to get your hands on a blow torch, too? Before you pull your old Schwinn out of the garage, check out the wealth of educator resources that support Musical Bike.
