1. To Prove: that the Earth’s atmosphere works
as a blanket to trap in heat.
2.
3. Start with two glass jars.
Place a thermometer in both of them.
Put the clear plastic lid on one of the jars and
leave the other open.
Shine the light on both jars.
Write down the temperature on both
thermometers.
Leave the jars for ten minutes and listen to
your teacher, for the next instructions.
4. Your teacher will give out each group a set of
picture cards.
As a group put your cards in order of the
LEAST amount of CO2 being emitted, up to
the picture of the LARGEST amount of CO2
being emitted.
Discuss the answers with your groups, with
your teacher and as a class.
5. What do you notice about the temperatures in
both of the jars?
Turn off the lights over the jars. What do you
notice about the temperatures?
Why do you think the temperature of the jar
that HAD a lid stays warmer than the
temperature in the jar that had NO lid?
How does this demonstrate that the
atmosphere works like a blanket?
6. And remember – use the recording layout of
a scientist as practiced in class!
