To assess the results of IBSE is not an easy task and it takes a long time. The teacher should be aware that the student learns new things through these activities, and therefore the teacher should not make comments, which could cause a loss of motivation. In addition, the teacher should ensure a safe environment in the classroom; i.e. nobody should laugh when the other student made a mistake. The possibilities of assessment differ from activity to activity. Not only knowledge is assessed, but first of all the skills and attitudes. It is necessary to proceed with students in slow steps through the individual phases of IBSE, always to provide a feedback on their progress through a formative assessment, not grading.
The output of activities 1, 9, 10, 12 is to develop the materials that can be used when working in other activities. After these activities, students can discuss whether the prepared materials contained all the important information, what their quality was and whether anything was missing or was irrelevant, etc. The activities 2, 3, 5, 6 to 8 are related to the application of knowledge and understanding of context. Each activity should be concluded with a feedback, on the basis of which the teacher can assess with the students to what extent the new information on water has been built into their own ideas and knowledge. The teacher can assess whether the student
