1. New Topic: Religion - Environment and Medical Issues Today’s Lesson: Global Warming Next Lesson: Effects of pollution on the environment

2. KQ : How does global warming affect the earth? LO: To distinguish between global warming and the ozone layer To explain the causes of global warming To suggest some possible solutions to global warming and justify your own opinions. STARTER: Who’s right? Why? Write your own definition of global warming The reason why global warming is happening is because there are holes in our ozone layer What??? I thought global warming was because the atmosphere was getting thicker TIF: Is there a difference between the ozone layer and atmosphere?

3. Atmosphere The sun produces infrared heat (IR) to warm the earth Some of this heat remains in the earth and some is reflected back into space The atmosphere protects the earth from getting too much IR As Co2 emissions increase, the atmosphere gets thicker so the excess IR cannot escape This causes the earth to heat – global warming TIF: How can human activities increase co2 in the atmosphere ? Ozone Layer The earth is also surrounded by the ozone layer This protects the earth from ultra violet light (UV) coming from the sun This light has no heat Man made products that uses CFC gases from things like aerosols damages the ozone layer Over time, this created a hole which has exposed the earth to direct UV TIF: Where is this hole in the ozone layer? Why is this harmful to humans?

4. The ozone layer is the same as the atmosphere? Global warming is to do with Infra Red? UV light from the sun gives us heat? Too much CO 2 can thicken our atmosphere ? Holes in the ozone layer cause global warming? TRUE FALSE

5. I don’t care about Global Warming. We can’t stop it anyway… I like the sunshine and long hot summers. I say, bring it on!! Do you agree or disagree? How to justify your opinion in writing: 1.Explain what your opinion is 2.Use an example to explain why you think that. This is the justification! Step 1 – 1 point and a suitable example to justify the point: Swap Books Step 2 – add a second point to support the same side and a suitable example to justify the point: Swap books Peer Assess

6. Learning Goals You must be able to distinguish between global warming and the ozone layer You should be able to explain the causes of global warming. You could be able to suggest some possible solutions to global warming and justify your own opinions.

7. Key words challenge… match the keywords to the correct statements and write them in your glossary Stewardship the increase in the temperature of the earth’s atmosphere (thought to be caused by the green house effect) Environment protecting and preserving natural resources and the environment Conservation the surroundings which plants and animals live and on which they depend to live Global Warming Looking after something so it can be passed on to the next generation

8. Causes of Global WarmingEffects of Global WarmingPossible Solutions https://www.youtube.com/watch?v=n94lepehpm4 https://www.youtube.com/watch?v=ktwBR0ELmvY As you watch the videos write short notes to fill in your table

9. Causes of Global WarmingEffects of Global WarmingPossible Solutions Burning of fossil fuelsChanging patterns of precipitaion Electric cars, hybrid Greenhouse effectDiseases like malaria returning to places where it was eradicated Use more energy efficient shower Solar radiationExtreme weather events – floods, droughts, heatwaves, more powerful hurricanes etc Carpool DeforestationSpecies extinctionRecycle, plant a tree, etc

10. The Greenhouse Effect 1) Heat and light energy reach us from the sun… 2) …a lot of this heat is reflected off the Earth’s surface… 3) …some of the heat escapes back into space… 4) …while some of it is reflected back to the Earth – this is called The Greenhouse Effect

11. Global warming at a glance... Global warming is the consistent increase in the temperature of the earths atmosphere https://www.youtube.com/watch?v=n94lepehp m4 https://www.youtube.com/watch?v=ktwBR0EL mvY https://www.youtube.com/watch?v=VTfgNFz1D BM

12. Learning Goals You must be able to distinguish between global warming and the ozone layer You should be able to explain the causes of global warming. You could be able to suggest some possible solutions to global warming and justify your own opinions.

13. EQ: Part c - Explain what people can do to reduce the effects of global warming. ( 8) Use Firstly, Secondly, Thirdly/Lastly Use because and/or therefore Use the words in the question Three PEEL paragraphs Remember: QWC

14. Swap your exam answers with another group. Award a mark for content: /6 Award a mark for QWC: /2 Award a total mark : /8 Write a ST and LT comment Subject Target (ST) 1.Only one point per paragraph 2.Explain another reason 3.Explain points clearly and fully 4.Read the question carefully to avoid misinterpretation 5.Use the words from the question in your answer Literacy Target (LT) 1.Use keywords 2.Pay attention to QWC 3.PEEL each paragraph 4.Use suitable examples 5.Spelling/Capital letters punctuation EQ: Part c - Explain what people can do to reduce the effects of global warming. ( 8)

15. Plenary Write down a question you can answer based on what you have learnt this lesson. Your question must link back to today’s learning goals. Be prepared to answer each others questions. You must be able to describe the difference between global warming and the ozone layer You should be able to explain the causes of global warming You could be able to suggest some possible solutions to global warming and justify your own opinions.
