Play the Carbon Cycle game and locate the following pieces of information as you travel. You may not travel the same order that I did, so the questions may not be in the order found below. You do not need to restate or answer in complete sentences.

A.) The compound, carbon dioxide, is made of ... and how many of each? (2pts)

B.) Why is carbon dioxide pulled out of the air? (1pts) Because plants and other organisms need it as energy to survive
C.) If atmospheric carbon dioxide levels continue to increase, plants will take in more carbon dioxide and grow faster. TRUE OR FALSE (1pt) True
D.) How much carbon is stored in soil/land? (1pt) 3%

E.) Does cold or hot water absorb carbon faster? Why? Make an inference here!
(This part is not in the game) (2pts)
Cold water absorbs carbon faster because it doesn’t try to spread, It all comes together.
