At Fremont Peak in 2000 with the 16 inch telescope built for Chaffey's Astronomy class



Chaffey High School is unusual in that it offers a course in Astronomy meeting the University of California's A-G entrance requirements for a science elective. Astronomy I is a two semester course that introduces students to the universe, its motions and the laws that govern it.  We engage in many hands on activities in the classroom and outside the classroom.  Since Ontario suffers from severe light pollution, we spend many evenings viewing the sky from the Mt. Baldy area using several telescopes ranging in size from a 6-inch Newtonian reflector to Mr. James' 16-inch Dobsonian (shown at right). The course pre-requisite is a B or better in Algebra I, a B or better in Earth Science, and instructor approval. Click here for the course syllabus.
