Science Olympiad

Science Olympiad is nationwide competition where students compete in topics including earth science, biology, chemistry, physics, and engineering. Science Olympiad is designed to increase a student’s interest in STEM fields and provide recognition for outstanding achievement in team events.

We're excited to start the Bay Area Elementary Science Olympiad Tournament for the 2022-2023 academic year.

Our Castro Valley High School Students are wearing purple shirts with the CVHS CupNoodles design. Please ask any of them for help if you need it.
The Aerodynamics, Pentathlon, and Straw Egg Drop events are open to spectators, but please refrain from speaking directly to competitors during the event.
We have shepherds who will congregate just outside the main gym about 5 minutes before each timeblock to lead the students to their events. Look for the high-schoolers in purple shirts waving signs for each event..
Our super coach Kathy will be giving an informational presentation for parents on the transition to middle school Science Olympiad for those interested in joining a Castro Valley team next year. This will be held in the Aux Gym from 8:40-9:10.
We have snacks for sale in the main quad! Proceeds help send our Castro Valley High School team to the National Science Olympiad Tournament in Kansas next week.

3/2/23 Update: Homeschool Students

Participation through a Local Public School: If the state in which a homeschooled student resides allows homeschooled students to participate in public school activities, homeschooled students may choose to participate as a member of the Elementary Science Olympiad team at the local public school they would attend were they not homeschooled.
Participation through a Homeschool Team: If the state in which you reside does not allow homeschooled students to participate in public school activities then a Homeschool Team may be created. This team can only consist of homeschooled students who live within the boundaries of two contiguous, side-by-side, geographic counties in a single state.
