Killer Crabs! (Food web disruption)

Russian king crabs have invaded Norwegian waters! They are competing with cod for their food. Students should already have an understanding of food chains / webs and competition. This lesson allows them to apply their knowledge to this scenario, and make decisions about the future of a fishing company who operate in the Norwegian waters.

I made a video starter featuring the cod and crab discussing their situation, with the Rocky theme music, and bad Russian and Norwegian accents - which the kids loved! A great activity for mid-high ability learners. Link to the video is in the lesson plan, in a separate document, and also here (links in the description are no longer allowed, but just search YouTube for DZ51RdBDJt4 and it’s the first result)

I designed these resources to support a free activity produced by Science UPD8. Their original file is included as it is hard to find online at the moment. The activity sheet will need copying to produce the cards needed for learners to build the food web on their desks. The lesson plan mentions an interactive drag and drop activity which is no longer supported by most classroom software.
