Laboratory work is a big part of chemistry education in high school. During our student training placement we have noticed that the laboratory work is not fully utilized to develop students´ chemistry knowledge. This problem made us want to investigate how the laboratory work in chemistry could be set, to become more meaningful for students. We introduced two preparation methods, and examined the outcome of students learning experiences and their acquisition of chemistry knowledge. This was examined both through surveys and observation. Our study showed that it is not clear that students learn by experimenting. Several students expressed that an initial discussion did contribute to an instructive laboratory sessions and claimed that the preparation had helped them to articulate their knowledge and that it helped them to focus on the right things during the experiment. The students who had prepared themselves communicated in a more scientific manner during the laboratory work.
