Principle

The Geiger-Müller counter tube measures the number of pulses in the sample and then calculates the statistical variation and relative error.

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 investigate the fluctuations in the registered count rates of the Geiger-Müller counter.

Learning Objectives

The special features of radioactivity are the statistically fluctuating processes. These should be made clear to the students in the experiment. In addition, the pupils should learn that the more statistical pulses of the individual measurement are smaller, the more pulses are recorded by the Geiger-Müller counter tube.
