ACSEF Giving Tuesday

Our Nonprofit Operation Depends on the Generosity of Donors

We are writing to let you know our current funding levels are not enough to support a highly successful and interactive in-person science fair as we did in 2023.


We are looking for your financial support to keep our funding on target on Giving Tuesday, 11/28/23, or anytime before December 31st at which time we need to make the hard decision of virtual vs in-person.

Our fair depends on the generosity of donors to keep providing opportunities to the future scientists and engineers of tomorrow!
