Measurement of UV radiation with Cobra SMARTsense

Principle

UV radiation is highly energetic, damages the skin and can lead to skin cancer in the long term. In this experiment, the irradiated energy of the sun's UV light is measured under different environmental conditions and it is investigated which UV-absorbing materials protect against UV radiation and to what extent.

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

1. Measuring UV radiation as a function of the position of the sun, cloud density and the time of year

2. Investigation of different UV light-absorbing materials

3. Investigation of artificial sources of UV radiation

Learning Objectives

• UV-A, UV-B, UV-C

• Quantification of UV radiation

• Protective measures against UV radiation
