A practical lesson where students work scientifically and develop their literacy skills by writing a conclusion using the ‘Point Evidence Explain’ technique from English. The context of the lesson is the work of Dr Helen Findlay who is investigating ocean acidification: ‘the other carbon problem’. This introduction to the carbon cycle and ocean acidification builds on students' prior knowledge of climate change and increased atmospheric carbon dioxide.
- Understand the wider context and learning outcomes
- Describe patterns
- Use the ‘Point Evidence Explain’ technique
- Explain the difference between correlation and cause
- Demonstrate and reflect on learning
- A Brief from Dr Helen Findlay (10 mins)
Use the slides to set the context and share the learning outcomes.
- Weird correlations and P.E.E. (Point Evidence Explain) (15 mins)
Highlight that correlation doesn’t mean cause using tylervigen.com/discover. Using slides, students learn how to write a conclusion with the ‘Point Evidence Explain’ technique.
- Practical work (10 mins)
Students look for evidence that CO2 causes ocean acidification during the activity ‘Ocean acidification in a cup’.
- Causal link: mechanism for ocean acidification (10 mins)
Using slides, students learn how increasing atmospheric CO2 is causing oceanic pH to decrease.
- Writing a conclusion (10 mins)
Students demonstrate their learning by writing or improving a conclusion.
- Self-reflection (5 mins)
Using slides, students consider how alternative ‘teachers’ may have delivered the lesson.
