IMAGINOLOGY is an annual free community event at the OC Fair & Event Center which focuses on S.T.E.A.M. (Science, Technology, Engineering, Arts and Math). For two days (April 9-10, 2022), curious children can explore S.T.E.A.M. through hands-on activities, exhibits, workshops, arts and crafts, competitions, and more! Admission is FREE and most activities are included. Get the details below!

NOTE: Open Saturday and Sunday 10 a.m.-5 p.m. Admission is free and most activities are included. Parking is $10. Limited food options will be available for purchase. Imaginology was canceled in 2020 but held virtually in 2021. The OC Fair-produced event began as Youth Expo and was later renamed Imaginology and focused on STEAM, offering a weekend of free family activities. Health and safety note: All OC Fair & Event Center visitors must follow current state and local health & safety protocols at the time of the event.

The deadline for online entry submissions is March 30. Projects will need to be dropped off April 16.
  • Centennial Farm: Imaginology visitors can check out the amazing animals and California crops on the three-acre working farm and enjoy an oxen exhibit, blacksmithing, chick education, radish-seed planting, terrarium-making and the OC Beekeepers exhibit.
  • Free activities: Learning about STEAM while having fun is the aim of Imaginology and exhibitors will offer things to do and see. Family-friendly entertainment will also be featured. Fort Blisters Boot Camp, located near Heroes Hall, is returning so kids can enjoy fun physical activities.
  • 4-H competitions: Local youth are judged on their abilities to raise small livestock, their understanding of animal and veterinary sciences and their projects on a variety of topics. Judging will take place at Imaginology
