Feast your eyes on the event slate for 2022-23 season!

Every year, our CVHS students are tasked to lead a Elementary Science Olympiad or a STEAM Summer Camp!

The summer of 2022, the CVHS SciOly ExComms and several student leaders lead a very successful hands-on in-person STEAM Summer Camp which included 12 amazing events such as Circuits, Crime Busters, Spaghetti Towers, Solar Systems, balloon cars, and more! Check out the photos from our camp below.

CVHS Science Olympiad Club spearheaded CV’s first virtual summer STEAM camp for the CV Elementary School students.    Below are the CVHS STEAM TEAM Event Supervisors and the events they taught.

“Dylan had loads of fun and was very engaged. Thank you for organizing such a great event and patiently explaining to the kids.”

“Brandon loved it and said he would do it again. He liked that he had all the materials and was able to follow along. Organizers were very prepared and spoke very well. They took time to explain and also keep the kids engaged.”

“Naina loved it a lot. And kudos to the CVHS student teachers, the events were presented well and interesting to kids. And thank you to the head coaches. Wish this was longer 🙂.”

“Miles enjoyed both Gummie Bear Osmosis and Density Towers activities. “It was great!””
