The seaweed solution

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 then use this information to develop an infographic that uses numbers to convince their peers to eat more seaweed.

Learning intentions:

Students will...

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

Success criteria:

Students can...

• solve connect fractions, decimals and percentages and carry out simple conversions
• find percentages of quantities and express one quantity as a percentage of another, with and without digital technologies
• recognise and solve problems involving simple ratios
• develop an infographic that uses numbers to convince peers to eat more seaweed
