This physics laboratory manual is the result of curriculum development begun at Aviation High School (New York City) in 1967. It represents a semester of advanced laboratory work for those students who have completed the usual course in physics. The 91 laboratory experiments included in the manual have been developed and modified through use for three consecutive spring semesters with high school seniors. They have been designed to require the student to do research in the classroom reference library. The laboratory materials needed for the experiments are readily produced by the teacher. It is intended that the students should work independently or in small groups, with many experiments running concurrently. Suggestions are made for implementing this or a similar program in the high school curriculum. (RS)
