The background effect with Cobra SMARTsense

Principle
Radioactive radiation pulses are registered with the help of the Geiger-Müller counter tube.
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
The pupils should check whether the Geiger-Müller counter registers pulses even though there is no radioactive source in the classroom.
Learning objectives
This experiment should enable the students to independently come to the conclusion that radioactivity is a natural process.
