A few years ago, I put together some engineering challenges based on my Recycled Science book. I thought I would gather them here in case they are useful during these tough stuck-at-home times. If you have the book Recycled Science (paperback or library binding), try these challenges to push your creations. If you don’t have the book, try your library’s e-book collection, or just eyeball the contraptions here and see if you can figure out how to join in.

(Teachers and Librarians, here’s a link to a free STEM station with these challenges and others for use once in-person gatherings resume.)

See the links below for videos of my engineering process and each challenge. Send me pictures or videos of your own attempts!
