Principle

In a classroom many people sit together for several hours. Especially in winter, when there is little ventilation, the CO2 concentration in a room increases and can be measured.

Benefits

• Especially understandable and didactically prepared description of the experiment (relevance to everyday life, etc.) including protocol questions.
• Future-oriented teaching: Integration into digital science lessons with tablets or smartphones.
• Increased motivation of students by using the intuitive measureAPP.
• Increased media competence.

Tasks

• Pupils will use the Cobra SMARTsense CO2 sensor to measure the CO2 level in a classroom at different times of the day.

Learning Objectives

• Pupils should realize that their breathing causes the CO2 content in the air to rise, especially in a closed room.
