In this double lesson, students can apply their knowledge of ecological rucksacks by preparing a survey on this topic. To do this, common consumer items must first be identified and their ecological rucksacks determined.
If the plan is to organise the survey openly, the pupils must be introduced to the use of cameras in order to document the survey. It is easier to develop the questions in advance using the multiple choice system in order to distribute them as a questionnaire. In this case, the questionnaires must be prepared in advance. The framework and target group for the survey should therefore be discussed in advance. In addition, it must be determined which method the students want to use.

Cameras or smartphones with a camera function must be available for an open survey. Students will need laptops and the internet to research the questions. Laptops and printers are also required to create the questionnaire.
