BeMED 7. Accumulation
Activity 3 of 3 about plastic pollution
|Preparation Time||3 minutes|
|Estimated Duration||30 to 45 minutes|
|Site||Gym/ Yard / Outdoor space|
|No. of participants||Whole class|
|Educational objectives||This is a fun physical education activity with the aim of teaching students about micro-plastics and our impact on the sea, fish life and our health. This activity provides a realistic and practical example of how micro-plastic accumulates in the food web.|
|Learning Outcomes||– Speed. Agility. Stamina. Quick reactions.
– I understand that I am responsible for my actions and am capable of anticipating the problems of consuming plastic and adapt to reduce it.
|Link to SDGs
|SDG 12: Responsible consumption
SDG 14: Life below water
SDG 15: Life on Land
|Remote preparation||Playing ‘Uncontrollable’ (Lesson plan 5) and ‘Plastic Breakdown’ (Lesson plan 6) before this activity will prepare students for this activity, however this is optional.|
|Equipment needed||Three types of coloured bibs
· 6 green bibs
· 4 yellow bibs
· the rest (according to number of participants) red bibs
Internet connection is needed to watch the video links provided in the background information.
|Method||Objective: Catch your food
Small Fish (S) – 6 students wearing green bib (or any other colour)
Medium Fish (M) – 4 students wearing yellow bib
Top Predator Fish (P) – 2 students
Fish Food (F) / Plankton – The majority of the remaining students wearing a red bib (FR). It is VERY IMPORTANT to leave only a few without bibs (F).
Playing the Game
Part 1: Fish food is eaten by small fish
· The playing area represents the Ocean
· The fish food run in the Ocean
· Instruct the small fish to go and eat (catch) all the fish food.
· For now, the other fish are waiting.
· Whenever a fish food is caught, he/she is transported to a designated captured area where they will remain. Everyone keeps a record of how many fish food they captured.
Game is paused when all fish food is caught.
Part 2: Small fish eaten by Medium fish
Medium Fish introduced. Now the small fish will be eaten by the medium fish and transported to the captured area.
Part 3: Medium fish eaten by the Top Predator fish
Top Predator Fish introduced. Same as part 2 and the game ends here.
Part 4: Explanation
See Recap section below
|The reason for the fish food with the red bib (FR) is now revealed. They are the micro-plastic. The others are the actual fish food (F). The small fish do not know the difference so when they eat, micro-plastics enter the food web. The higher the food web hierarchy, the more micro-plastic accumulation. Apart from killing marine life, when we humans eat fish especially the top fish, we inevitably also ingest the micro-plastics.
Actions students can take:
· When encountering plastic rubbish, try to dispose of it properly, if this is safe to do so.
· Refuse unnecessary plastic
|Follow-up activities||This is the last of 3 activities, the previous being ‘Uncontrollable’ and ‘Accumulation’, covering the plastic pollution topic which integrates PE and ESD subjects.|
