Activity Introduction

 

In this lesson, students will access information about seaweed farming and greenhouse gas emissions and use percentages, ratios, and fractions to solve problems.

 

Students will also investigate the relationship between seaweed farming, the health benefits of eating seaweed and climate change. They will use then this information to develop an infographic that uses numbers to convince their peers to eat more seaweed.

  • Students will understand fractions, decimals and percentages
  • Students will understand simple ratios
  • Students will learn how seaweed farming can help reduce CO2 emissions and therefore help combat climate change
  • Students will understand the relationship between seaweed farming, the health benefits of eating seaweed and climate change

Thought starter: What's so great about seaweed?

"Most of the world’s oxygen, about 70%, comes from seaweeds and algae. It is estimated that there are about 9 times more seaweeds in the oceans than there are plants on land." (Seaweed Enterprises Australia, https://www.seaweedenterprisesaustralia.com.au/blog/post/3658/9-amazing-facts-about-Seaweed/)

1. Watch this clip:

Marine Permaculture Password: 2040_EDU (https://vimeo.com/showcase/6167669/video/336507628)

Note down any unfamiliar words or phrases you hear in the clip.

2. Go to http://www.globalcarbonatlas.org/en/CO2-emissions and click on 'Chart View'.

Find Australia by looking on the bar chart or entering 'Australia' in the 'Countries' text box on the left.

How many MtCO2 did Australia emit in 2017?

.

Now work out how much of Australia’s emissions went into the ocean without using your calculator.
(Hint, 25 percent of all CO2 emissions are absorbed by our oceans.)

Express your answer as a mixed fraction and a dec
