Attend the free OC Fair Imaginology Youth Expo in Costa Mesa from April 13-15, 2018. There is free admission on Friday for students and chaperons.

Have you ever wondered how math can help you cook … or what causes a rainbow … or how baby chicks know when to hatch?  Set a course for full STEAM ahead to OC Fair’s Imaginology, April 13-15, where science, technology, engineering, art and math come alive in the most fun and exciting ways.

 OC Fair Imaginology Youth Expo in Costa Mesa

At Imaginology, kids and their families will not only see a world of wonder, but can participate in a wide range of fun and educational hands-on activities designed to inspire and encourage academic and career exploration.  We have attended several years in a row and love it every time.  There is always a wide variety of new and interesting activities to peak my children’s attention.  Here’s a look at years past!
