Laboratory work is essential in the study of physics. The primary goals of introductory physics laboratories have been evolving over the past century. The current impetus for changes in laboratory instruction stems from new research on student learning and technology, as well as changes in the overall goals of physics instructors.The laboratory should help the student develop a broad array of basic skills and tools of experimental physics and data analysis.

While it is imperative that students have a broad experience with techniques using laboratory equipment, it is impossible to prescribe precisely which equipment should be used in all introductory laboratory courses. The learning objectives of each laboratory experiment should determine the equipment to be used. At the same time, it is advisable to have students use many different types of basic laboratory apparatus to make observations.
