Unit 10:
Sources of energy
Lesson 1: Getting Started
Sneak Peek
Who are they?
What are they talking about?
What is a different type of footprint?
a. Read and underline keywords.
1. What is a carbon footprint?
2. What does `non-renewable energy` mean?
3. Why is sunlight a renewable source?
4. Why does Mai think she has a small carbon footprint?
5. What things do you think might create a big carbon footprint?
Ex 1:Listen and read
Mai: Nam, I read yesterday that we all have a carbon footprint. 
Nam: Well, we all have footprints - we make them with our feet! 
Mai: Ha ha, I know that. But this kind of footprint is about the negative effect we have on the environment. 
Nam: Right, it’s in the news a lot these days. 
Mai: So our footprint is bigger when we use energy that produces carbon dioxide. That’s bad for the environment. 
Nam: So it’s better to have a smaller footprint, right? 
Mai: Right, Nam. Non-renewable energy sources like coal, natural gas, and oil produce a lot of carbon dioxide. Those sources are going to run out soon too. 
Nam: So, they’re different to wind, hydro, and solar? 
Mai: Yes, they’re all sources of energy too, but they’re renewable. That means we can’t use them all up - they will last forever. 
Nam: Do you have a big carbon footprint, Mai? 
Mai: Mine’s small. I recycle the products I use and I go everywhere by bike. We have solar panels on our roof at home to catch the sun’s energy, too. 
Nam: Oh no! I think my footprint is big, and not just because of these big shoes! 


a. Read again and answer the questions.
1. What is a carbon footprint?
2. What does `non-renewable energy` mean?
3. Why is sunlight a renewable source?
4. Why does Mai think she has a small carbon footprint?
5. What things do you think might create a big carbon footprint?
It’s about the negative effect we have on the environment.
‘Non-renewable energy’ means that it will run out if we use it.
Sunlight is a renewable source because we can’t use it all up, it will last forever.
Mai thinks she has a small carbon footprint because she recycles the products she uses and she goes everywhere by bike.
The products we use that are bad for the environment or the energy we use that produces carbon dioxide might create a big carbon footprint.
B. Complete the network

planet to the Sun and the

System
Neptune
Neptune is the farthest planet from the Sun and the fourth-largest by diameter in the Solar System
Jupiter
Despite being red, Mars is a cold place. It’s full of iron oxide dust, giving the planet its reddish cast
