The document discusses the purposes and processes of laboratory work. Laboratories are planned learning activities that involve hands-on experience with raw data to solve problems. They allow students to observe, reason, and improve their understanding of scientific inquiry while developing problem-solving and independent work skills. Both teachers and students have defined roles and responsibilities to ensure laboratories are properly planned, supervised, and evaluated.
