Understanding Climate Change Year 7 Science Environmental Studies
What Do You Already Know?
What does 'global warming' mean to you? What might cause the Earth to get warmer? What changes have you noticed in our environment? How might a warmer planet affect New Zealand?
Key Vocabulary: Global Warming
The gradual heating up of Earth and sea Increases the average temperature of our planet Example: 'Global warming is causing ice caps to melt.'
Vocabulary Practice: Global Warming
Which sentence uses 'global warming' correctly? A) Global warming makes ice cream melt faster B) Global warming is causing changes to Earth's climate C) Global warming only happens in summer D) Global warming is when you feel hot
Vocabulary Practice: Fossil Fuels & Uninhabitable
Fossil Fuels Fossil fuels are coal, oil, and gas that are burned for energy. Example: Cars use fossil fuels like petrol. Choose the correct word for each sentence. Work with a partner to discuss your answers. Uninhabitable Uninhabitable means a place is too dangerous or damaged to live in. Example: Extreme heat can make some areas uninhabitable. Choose the correct word for each sentence. Work with a partner to discuss your answers.
Key Vocabulary: Fossil Fuels

Reading Check: Human History and Technology
According to the text, why have humans invented new technologies? What has happened since the industrial revolution? How have these inventions changed our lives? What problem has this progress created?
Causes vs Effects of Global Warming
{"left":"Burning fossil fuels (coal, gas, oil)\nIndustrial revolution inventions\nMore carbon dioxide in atmosphere\nHeat trapped by greenhouse gases\nPolar ice caps melting","right":"Rising sea levels\nFlooding of coastal areas\nChanges to animal habitats\nHeat waves and droughts\nSpread of heat-loving diseases"}
Reading Check: Future Consequences
What might happen to polar ice caps? How could rising sea levels affect people? What changes might happen to plants and animals? How could farming be affected?
Comprehension Check
True or False: Global warming only affects polar bears Humans are the main cause of current global warming Small temperature increases don't matter Creative thinking can help solve these problems
Think and Discuss
What creative solutions can you think of to reduce fossil fuel use? How can young people like you help fight global warming? What changes could our school make? What gives you hope about solving this problem?
Remember This
We need to engage our creative thinking and find ways to solve these problems while we still have time. - From our reading text
