How does ocean acidification affect communities? KS3 Science
Students work scientifically by developing and using a model (a food web) to formulate hypotheses.

The context of the lesson is Dr Ceri Lewis’ investigating how ocean acidification might affect the plankton at low trophic levels and the cascade effects at higher levels. The lesson builds on students’ prior knowledge of interdependence.
