Sloan Museum of Discovery and Longway Planetarium staff will be here to help children aged 4-12 years old work together using interesting everyday materials in new and interesting ways. Build an obstacle track that moves your marble from one place to another. Can you join your marble machine with someone else’s? How far can you and your friends make the marbles move? Open to children aged 4 years old or older only. We're limited to 25 kids in each session, so please register for either the 11am, 1pm, or 3pm session.

Children aged 12 years and under must be accompanied by a responsible caregiver (aged 16+) who remains on the premises for the duration of the program.
