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

This is the weather a certain place

There are many beautiful
animals in taiga
The

In the Arctic the
winter
temperatures
are low enough.
But unfortunately the weather is
changing…
Let’s watch the video from the
Internet and answer the following
questions

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?
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.

The greenhouse effect
1
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.

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