Tracking the return of the salmon with GeoMaps
Earlier in history, the salmon was regarded as cheap food for workers and servants, because it was nutritious, filling and plentiful in the rivers. For centuries in Germany it was caught by the ton. But from the mid-1960s till today it virtually disappeared from our rivers and ever since has only been fished out of the sea or bred in large fish farms. However, nowadays the wild salmon are returning to our inland rivers and lakes as well.
With the help of digital map services, children and teens systematically explore and reveal the salmon’s original habitat and the waterways. In this lesson they will search the Internet to find out about the interactions that occur between these organisms and systems in which they exist, and learn what factors can lead to the extinction of certain species.
Through their encounters with and exploration of the natural habitats and ecosystem changes, children and teens ability to reflect upon and make certain judgements will be trained. By the end of the lesson, they will be able to learn about the topic of habitats from various perspectives and develop their own positions.
Project procedure

The project “5,000 km against the current” is suitable as an introduction to the study of habitats and offers the opportunity to develop basic principles for a deeper understanding of nature and an understanding of complex processes in (natural) systems. It has a strong practical focus, and the project work is linked to the children and teens own environment.

Working with their partners, the children and teens take the salmon’s habitat and waterways to hand – and in doing so, they learn all about the use of digital mapping services. Their Internet research goes in-depth into special particularities of this fish. Along the way, they follow the question of what factors have led to the salmon’s decimation. In a subsequent discussion of the lesson with the whole group, they evaluate the results of their research and present their findings.

Further aspects can be integrated into the project, too, such as procedures for the determination of flora and fauna, as well as researching, classification and systematization of physical characteristics, for example.

To get started, the children and teens learn about the original habitat of the animals, their natural surroundings and ecosystems. On the basis of an article on the return of the salmon to the Rhine river, they retrace the stations of the salmon migration using a Geomap. They create their own routes following the journey of the salmon and add comments and pictures.

Recording results: GeoMaps
Social form: partner work
After the migration of the salmon has been sufficiently covered, the children and teens go further with their partners and deepen their knowledge by studying the peculiarities of this salt- and freshwater fish. They do independent research online and record their search results in a Word document.

Recording results: Word document
Social form: teamwork
After children and teens have developed a basic understanding of the habitat and this species of fish, the salmon, they ponder what factors might have led to the decimation of this remarkable fish in Germany. They also research on the Internet and put together the research findings/insights into their Word document.
They then present the routes that they have created and discuss their research results in the learning group. All of the relevent aspects will be collected in a class mind map.
Recording results: GeoMaps
Social form: group discussion

The procedure of the project is transferable to all regions and habitats. Similarly, the project procedure can be transferred to any other endangered migratory fish or migratory bird species. The main points can be weighted differently or expanded upon according to context. Comparisons could be drawn thusly, for example, between the salmon migration in 2 rivers such as the Rhine and the Elbe.
