Learning Intentions
Identify Key Polluters: Learn about the main sources of pollution in the Great Pacific Garbage Patch.
Understand Ocean Factors: Understand the various factors that shape our oceans.
Analyse Polluted Areas: Analyse the locations of polluted rivers and ocean gyres.
Success Criteria
Success Criteria
Identifying Key Polluters: Students can name and describe at least three key polluters contributing to the Great Pacific Garbage Patch.
Describing Ocean Factors: Students can explain at least three factors that influence the shape and characteristics of our oceans.
Analysing Polluted Areas: Students can use maps to identify and explain the spatial distribution of polluted rivers and ocean gyres.
Task 1 - watch the video clip above.
Task 2 - Take a look at the map above. Notice the following:
a) the flow of the ocean currents (anti-clockwise/clockwise)
b) the direction (North/South) and
c) the temperature of the ocean currents (hot = red/cold = blue).
d) The direction of the winds (which push the ocean currents along).
Focus in on the Pacific Ocean. Remember the world is a globe, so the Pacific Ocean on the left is the exact same one as the Pacific Ocean on the right! This is where the Great Ocean Garbage Patch is situated.
For the next two tasks, you will be using GIS (geographic information systems) mapping software and research data on global waste found in the ocean. You will need to follow your instruction sheet very carefully step by step. Tick off each step as you complete it, before you move on to the next step.

Teachers - give link to worksheet and GIS map link to students.
NB - Task 3 and Task 4 below also link back to the worksheet.
For the mapping task - work in pairs - one student to have instructions open while the other opens the link to the GIS map.
Task 3 - Plastic is not so fantastic - Investigation.
Task 3 - Plastic is not so fantastic - Investigation.
Each year, more than 8 million tons of plastic ends up in the oceans, costing at least $8 billion in damage to marine ecosystems. World production of plastic materials in 2016 was 280 million tonnes.
These plastics degrade into tiny pieces of plastic, called microplastics, which can now be found in our soil, oceans, fish, food, even air!
According to a recent report by the United Nations Environment Programme, the three biggest culprits include single use plastic bags, disposable single use plastic items and microbeads.
Task 1 - Using the worksheet given to you by your teacher, complete the table using the information below which explores these three pollutants.
Task 4 - A Sea of Plastic - GIS
Task 4 - A Sea of Plastic - GIS
a) Open up the GIS map by clicking on THIS LINK.
b) Open up the student worksheet and/or look at the hard copy given to you by your teacher. Follow the steps under the 'explore' section very carefully to investigate the trillion tonnes of plastic floating in our oceans, and the processes behind it.
c) Answer all questions in your workbooks.
Extra Challenge Task - Open the National Geographic article below, read through each description on the left of each of the photographs. Then open the Doc on the right to read the task instructions.
