Sharing Best Practice
8D3 (07/07/17): I asked students to read a paragraph outlining how the greenhouse effect occurs. Students worked individually to select 6 key words. They then worked in a pair to further reduce and then as a class we discussed and reduced. The next task asked students to replace the text with a diagram/picture of global warming by using the information in the text. This worked with varying success, the brighter students worked well and a sample is attached. Weaker students needed more support and got hung up on “how do I draw a gas”.
Amazingly some students were able to produce a diagram very similar to that found in the textbook/online, without ever having seeing it before! Overall, the lesson went well. The boys enjoyed it. Timing was an issue and I will need to watch this. My next plan is to use another replace activity where students will have to answer the question ‘What can cause global warming? You may not use the words greenhouse effect, heat, gases or absorb in your answer’.
