The obsession in our house this week is building marble runs! Inspired by Roller Coaster by Marla Frazee, we built rollercoasters for marbles. This is the perfect book to teach kids how to write detailed small moments, but it was fun to use the book in a new way! . We used Duplos and tape to construct supports for pool noodles. It took a lot of persistence and troubleshooting. Such a great STEM project! The kids watch the marbles zip and zoom around the track over and over 🎢
