Environmental sustainability questions ask you to read evidence about the environment and reason from it. This page shows how the four skills connect and the order to learn them.
The topic belongs to SPM Science. Expect tables, graphs, flow diagrams and short proposals, and expect the marks to reward evidence over opinion.
What are the four skills in this topic?
Each lesson builds on the one before, so this is also the study order.
- Interpreting environmental indicator data: reading trends, units and gaps in a table or graph.
- Explaining pollution pathways: how a pollutant moves from source to effect.
- Comparing waste-management approaches: a fair comparison on stated criteria.
- Evaluating a sustainability proposal: benefit, limit and judgement, all backed by data.
Finish with the environmental sustainability practice set.
How do the skills meet in one question?
Take this example. A table shows a stream’s dissolved oxygen falling from 8 mg per litre upstream to 3 mg per litre downstream of a small factory. The question then asks for the cause and a judgement on a proposed filter.
Reading the fall is lesson 1. Explaining how waste can lower oxygen, for example by feeding microorganisms that use oxygen, is lesson 2. Judging the filter is lesson 4.
A full answer quotes the figures, names the pathway, and says what extra data would show whether the filter helped.
Who should start where?
If graphs and tables cost you marks, start with lesson 1. If you can read data but your explanations are thin, go to lesson 2.
If you write “recycling is good” without comparing, lesson 3 shows how to compare on criteria. If your judgements sound like opinions, lesson 4 teaches the benefit-limit-judgement pattern.
