Visual meteor observations are a fun and interesting approach to astronomy and to scientific research in general. It can be used for laboratory or practical exercises in physics at high schools and universities. The students can personally collect and analyze the acquired data. The output consists of Zenithal Hourly Rate (ZHR) values, spatial density and population index. In this paper, the so called counting method is described as it is the most suitable method for beginners. As a practical example, the ZHR curve of the Lyrid meteor shower was evaluated and the maximum and the duration of the shower were calculated.
