CO2
When the bubbles get
to the top of bottle and
come into contact with
the air, they pop and
release their CO2
The bubbles, carrying
the CO2, float to the top.
Every bubble in a
carbonated drink is
full of carbon
dioxide, which we
call CO2

The global climate is changing due to
humans burning fossil fuels (from gas
and coal).
Burning fossil fuels releases
carbon dioxide (CO2) into
the atmosphere.
CO2 is a greenhouse gas that
causes the earth’s surface to
warm up.

You’re going to play the role of climate scientists
today. Your goal is to determine how temperature
can affect the amount of CO2 that is in water.
Talk with your partner and come up with
some ideas of how you could do a scientific
investigation to answer the question:
Will warming
oceans be better or
worse at soaking up
CO2?
