• In the Spring, we have young scientists, from all over San Diego County, converge onto the Tierra del Sol Middle School campus here in Lakeside to participate in Science Field Day.  SFD is a wonderful opportunity for students in grades 4, 5, and 6 to compete in 15 science related events.  Each student generally participates in two or three events.  Many non-competitive events also take place throughout the day.  At the end of the day, the culminating activity is an exciting awards ceremony.
