Two ninth grade classes – one Swedish and one Danish worked together doing chemistry experiments. Their assignment was to seek out and choose an experiment to perform, then plan for and execute the experiment while making a videotape of the experiment to upload onto their mutual blog, and finally, to give feedback on the videos. Analysis of the students’ activities and the material they produced indicated that they attained the goals in relation to planning and documenting a science experiment. Their level of enthusiasm was deemed to be high, and they were apparently motivated by working with students from another school in another country. However, a deeper analysis of the experimental content showed that the specifically scientific learning was rather superficial, and would have benefitted from greater teacher guidance during the experiment.
