2020-21 Elementary Virtual Summer Camp

CVHS Science Olympiad Club spearheaded CV’s first virtual summer STEAM camp for the CV Elementary School students.    Below are the CVHS STEAM TEAM campers, the CVHS 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!””
