TK Visits Cypress Fire Station

During our Catholic Schools Week celebration last month, our Transitional Kindergarten students were asked to create a card of gratitude and provide a basket of goodies for the Cypress Fire Department. When delivering the items, the students were invited to tour the fire station. They also had the opportunity to learn about the equipment on the truck. They got to see the oxygen tanks, respiratory masks, and turnout coats that protect fire fighters from heat and moisture. We thank the Orange County Fire Authority and the fire fighters at the Cypress station for taking the time to visit with our students.
