Abstract This master thesis is divided into two parts, one pedagogical and one engineering. The purpose of the pedagogical part of this master thesis was to investigate how students learn during projects. At the Royal Institute of Technology in Stockholm, three larger student projects occurred where the students themselves developed an probe that was launched into the atmosphere. The supervisors of the projects wanted to find out how the students learn during the project. The thesis includes in-depth interviews with current and former university students. In order to compare and gain new perspectives on learning, the study also included interviews with high school students to identify their corresponding experiences of learning in their final projects in Swedish upper secondary school. The result from this study shows that the students learn through participating in activities, collaboration and communication. Giving the students responsibility, a mutual goal and an important assignment makes them collaborate and learn from experience through reflection. The purpose of the engineering part of this master thesis was to investigate samples that were collected during the Arctic Summer Cloud Ocean Study in the summer of 2008. The samples were studied by using a scanning electron microscope. The results of the thesis are consistent with former studies on samples collected in Arctic. The images from the microscope showed microgels and how the gels assembled into larger particles, particles which can play a crucial role in the formation of clouds.
