/ Pupils work in groups to label a simplified carbon cycle. This leads in to Activity G4a. / Pupils set up a 'grow your own greenhouse effect' on a window sill at the start of the lesson, and make predictions. They look at the results in a plenary at the end of the lesson. / Animation of carbon dioxide produced by a burning candle causing limewater to turn milky.
