LEARNING OBJECTIVE
2c.) Observe and describe chemical reactions involving atmospheric oxygen (e.g., rust, fire, respiration, photosynthesis).
VOCABULARY:
Atmospheric Oxygen: The oxygen that makes up part of the air we breathe.
Photosynthesis: The process of plants using sunlight to make sugar/food.
Combustion: A chemical change involving oxygen and fuel producing heat and light.
Rusting: The chemical process of combining oxygen with iron.
Respiraton: The process of combining oxygen with fuel/food to produce energy.

ESSENTIAL QUESTIONS KEY
1.) List at least 4 chemical reactions that involve atmospheric oxygen.
1.) respiration
2.) photosynthesis
3.) combustion/burning
4.) rusting
5.) oxidation of aluminum
2.) Describe how you know if a chemical equation/reaction involves oxygen?
the reaction will have an O2 in it. This represents atmospheric oxygen.
3.) Which substances are necessary for plants to produce sugar during photosynthesis?
A. water, soil, chlorophyll
C. water, carbon dioxide, light
B. water, minerals, cell wall
D. water, roots, oxygen
EXPLAIN YOUR ANSWER!!!!
C, these are the substances that go into the reaction.
4.) What are the reactants for
photosynthesis?
A. soil and chlorophyll
C. water and minerals
B. oxygen and carbon dioxide
D. water and carbon dioxide
EXPLAIN YOUR ANSWER!!!!
D, because they are on the left side of the reaction equation
5.) Why is atmospheric oxygen so important on planet Earth?
It reacts with many things.
6.) What do all the following chemical reactions have in common?
combustion
respiration
photosynthesis
rusting
A. they all involve iron
C. they all involve carbon
B. they all involve carbon dioxide
D. they all involve oxygen
