Active learning ideas
This topic addresses one of the most pressing environmental issues: plastic pollution. Students examine the chemical properties that make plastic so useful (durability, flexibility) and why those same properties make it a persistent pollutant. This aligns with the NCCA 'Caring for the environment' strand, encouraging students to evaluate their own consumption habits.
Activity 01
Groups collect and categorize the plastic waste from lunchboxes or the staffroom for one day. They create a bar chart of the types of plastic found and suggest three ways to reduce it.
Why are plastics so widely used?
Activity 02
Students debate the effectiveness of Ireland's plastic bag levy. One side argues for total bans on all single-use plastics, while the other discusses the practical needs of businesses and consumers.
What happens to plastic waste in the environment?
Activity 03
Students are given a common plastic item (e.g., a straw or a toothbrush). In pairs, they must sketch a design for an alternative made from sustainable materials and explain why it is better.
How can we reduce our reliance on single-use plastics?
A few notes on teaching this unit
Watch Out for These Misconceptions
All plastic can be recycled easily.
Many plastics are difficult or impossible to recycle due to their chemical makeup or contamination. Sorting a 'mystery bin' of plastics using recycling symbols helps students understand the complexity of the recycling process.
Plastic 'disappears' when it breaks down in the ocean.
Plastic doesn't biodegrade; it just breaks into smaller 'microplastics.' Using a magnifying glass to look for tiny plastic fragments in a sand sample can help students visualize this persistent pollution.
Methods used in this brief
Sourcing and Refining Materials
Students trace the origins of everyday materials, from raw natural resources to finished products. They examine the environmental impact of extraction.
8 methodologies
Renewable Energy and Conservation
Students explore renewable energy sources and the importance of energy conservation. They discuss the role of science in addressing climate change.
