Evidence of carbon and tree interactions

Agenda: Exit Ticket

Open Ended

If trees are made out of carbon, why would forest fires be contributing to global warming? (Hint: What is the smoke?)

Multiple Select

Select the three types of "sugars" trees make

• Simple Sugars

• Starch

• Cellulose

• Lipids

Multiple Choice

What is the job of cellulose?

• Structure and Support

• long term energy storage

• Daily energy for plants

Multiple Choice

What is the job of starch?

• Structure and support

• long term energy storage

• daily energy for plants

Multiple Choice

How could we test to see if this carbon dioxide is really going into the plants and oxygen is coming out?

Poll

The month is May and it is almost spring in the Northern Hemisphere. Are the current levels of carbon dioxide high or low?

• High levels of carbon dioxide

• Low levels of carbon dioxide

Poll

What do you think will happen to the carbon dioxide levels as spring and summer start?

• The CO2 levels will go up

• The CO2 levels will stay the same

• The CO2 L

Multiple Choice

What happened to the global CO2 levels during the summer?

• CO2 Levels went UP

• CO2 levels stayed the same

• CO2 levels went DOWN

Open Ended

Why did CO2 levels start rising again in the fall/winter?

Multiple Choice

"Plants developed in an atmosphere that had much more CO2 than that of the present. Logic would therefore tell you that if you have more CO2 in the air, plants will do better..." What is the claim that he is making? (cause and effect)

• Plants developed in an atmosphere with more co2

• There was more CO2 on our planet at one point.

• Oxygen is a by-product of photosynthesis

• If you have more CO2 in the air, plants will do better.

What was the experiment the scientists were doing?

As we put more carbon dioxide into the air, how will trees respond?
