The purpose of this paper is to explore and discuss the role of practical work in the teaching and learning of science at school level. It emphasizes practical work as a means for students to learn about the nature of science.
Reports from the NSF, NRC, AAAS, and others urge over and over that we must teach "science as science is done," that "science is a way of knowing," that our goal should be to impart "scientific habits of mind," and that learning must be learner-centered and oriented toward process.

Taken together these three domains have reshaped our thinking about the role inquiry, and in turn the laboratory, has in science
