Unit Summary
This unit introduces the greenhouse effect, global warming and the impact of climate change on weather events. It explores some actions that can be taken to use resources, and to live, in a sustainable way.
Lesson Summary
You will learn to explain what is meant by climate change and how it is related to human activities.
Key Notes
- The climate is the average weather conditions for a particular location over a long period of time.
- Emissions of greenhouse gases from human activities are causing global warming and climate change.
- Climate change includes an increase in the frequency of extreme weather events such as droughts, storms and floods.
- Data predict an increased frequency of extreme weather events with increasing global temperature.
- We all need to work together to reduce emissions of greenhouse gases to limit climate change.
Vocabulary To Learn
- climate: the average weather conditions for a particular location over a long period of time
- greenhouse effect: the effect of some gases in the atmosphere that keep Earth's surface warmer than it would be without them
- global warming: an increase in Earth's average surface temperature
- climate change: a long-term shift in weather patterns
- frequency: how often something happens in a given period of time
Common Mistakes To Avoid
- Thinking that individual weather events are evidence for or against climate change.
3 Quick Questions (With Answers)
1. Explain the scientific idea in this lesson using two key points.
The climate is the average weather conditions for a particular location over a long period of time. Emissions of greenhouse gases from human activities are causing global warming and climate change.
2. Define this scientific word and use it in context. 'climate'
the average weather conditions for a particular location over a long period of time. Include the word in a full scientific explanation, not as a single label.
3. Correct this common scientific misunderstanding.
Mistake: Thinking that individual weather events are evidence for or against climate change. Correction: The lesson explores the correct idea that an increase in the frequency of extreme weather events is evidence of climate change and we have to look at the long term pattern of weather events as evidence.
