For Families


When school is out, COSI is in! School's Out Camps provide the perfect opportunity for campers to stay scientific outside of school.

All camps include snacks and supplies. Parents and caregivers, please pack a lunch for your campers. Wrap-around care is available for $5 an hour between 8am and 9am and between 4pm and 5pm.

Dates are available throughout the year for all ages and this site is updated as new camps become available.

Camps Reservations are now available for all customers!

Wrap-Around Care
Available one hour before and one hour after most camps for an additional fee. All prices subject to change without notice.

Camp COSI Cancellation Policy:
Single-Day Camps
If you can’t attend your single-day camp, contact COSI at least 24 hours before your program. COSI will attempt to reschedule you into an open session. Refunds are not available. COSI can only reschedule a missed workshop once.

Five-Day Camps

Cancellations and changes must be made at least 10 days before the first day of any weeklong camp; a $40 cancellation fee applies. Refunds cannot be issued for cancellations made later than 10 days before the first day of a weeklong camp. COSI may cancel sessions if participant minimums are not met. Registered participants will be informed two weeks in advance and will receive a full refund.

Please note that selected COSI program reservations are subject to a nominal processing fee. Proceeds from this fee help to support COSI, a not-for-profit organization.
