Why don the lab instructions give the necessary theory?
This is to emphasize that the laboratory is an integral part of the entire course. The theory is available in the textbook and the preparation section for each laboratory gives which sections are to be read. Reading the text and doing the predictions and questions preceding each problem gives an adequate preparation for the lab. A computer check out is used to assure that each student has a basic understanding of the necessary text material before coming to class. Doing the lab problems should help, with the guidance of the lab instructor, clarify and solidify the ideas in the text and in the lecture.
