In this station training, students learn about the key concepts related to fish through worksheets and information sheets, as well as simple yet impressive experiments. At each station, they explore the different types of fish, how they move, the special organs they possess and how these function (gills, swim bladder, lateral line system), as well as reproduction and development. Additionally, special fish species (salmon and sharks) are examined in depth, and human usage behavior is critically analyzed. Students practice independent work, careful documentation, and systematic derivation of insights, as well as constructive collaboration. This allows for a comprehensive and engaging exploration of the topic of fish in biology classes with minimal effort. The volume includes: photocopiable templates for 18 mandatory and 4 optional stations.
