Principle

The students use the Geiger-Müller counter tube to investigate the dependence of the radiation intensity on the amount of potassium chloride.

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 students examine the radiation intensity when the amount of potassium chloride is increased.

Learning Objectives

The students use the experiment to explain the relationship between the intensity of radiation and the amount of radioactive substance.
