Laboratory Chemistry in Natural Science

University level laboratory work is reformulated to fit into the chemistry and natural science education in the upper secondary school of Sweden. This thesis describes how this reformulation is performed both from the chemical and the didactic point of view. The resulting laboratory manual has been tested by students in the target group with positive response. Interest lay in how to present laboratory experiments far different from what they usually did and how it actually connected to their studies in natural science. How much did attitudes and self-efficacy influence the implementation of the laboratory work…
