1. Global warming (an amateur investigation)
What is happening to the temperature?

2. Our Plan Centigrade and Fahrenheit
The weather forecast. Climate changes.
Climate in Russia.
The Truth About Global Warming. The Video and the pupils’ projects
The conclusion. Our totals.
The Hometask

3. Centigrade and Fahrenheit: what’s the difference?
°F = (°C x 1,8) + 32
°C = (°F - 32) / 1,8

4. The weather forecast What is the weather like today?
The Internet will help us!

5. Climate This is the weather a certain place
has over a long period of time.

6. Russia is the largest country in the world.

What is the key-question of the discussion?
What is the meaning of the red curve? When did the climate start to change?
What does the green curve mean?
Till what time do the red and the green curve go together?
What does the yellow curve mean?
What is the conclusion of this research? What does the model tell us?

18. greenhouse
The world is becoming hotter.That it is so because of the greenhouse effect. It works like this: sunlight gives us heat. Some of the heat warms the atmosphere, and some of the heat goes back into space.

19. The greenhouse effect Sunlight (1) gives the heat to the greenhouse.
It warms the greenhouse.
The heat can not go back
into atmosphere, because
there is a special glass
in greenhouses.

20. oxygen
carbon dioxide
carbon dioxide
oxygen
People and animals breathe in oxygen, and breathe out carbon dioxide.
Trees take this gas from the air, and produce oxygen.

21. Carbon dioxide
We and animals breathe in oxygen ,and breathe out carbon dioxide. Trees take this gas from the air, and produce oxygen.
