Hawaii QuarkNet Annual Report 2021-2022
There are five cosmic ray detectors currently in Hawaii but
not all take data regularly. About ten high school physics
teachers actively participated before the pandemic. Only one
event (CMS Masterclass on 12 March 2022) has been held since 2020.
Here is the agenda page that Shane Wood from QuarkNet and Tiffany Coke
from Punahou have pieced together for the Saturday, March 12
Masterclass:

About 20 students from Punahou High School participated. Three
QuarkNet teachers (Tiffany Coke, Charles Wade, Patrick Yim), Michael
Jones and Shane Wood participated in the lunchtime discussion.
Patrick Yim attended the Data Camp at Fermilab in July 2022.
