1. Biology Do Now
Directions: Take out a sheet of notebook (Do Now sheet) and answer the questions.
What are the inputs (reactants) of photosynthesis?
What are the outputs (products) of photosynthesis?
What are the inputs (reactants) of aerobic cellular respiration?
What are the outputs (products) of aerobic cellular respiration?

2. Biology Do Now Key
Directions: Take out a sheet of notebook (Do Now sheet) and answer the questions.
What are the inputs of photosynthesis? Carbon dioxide, water, sunlight energy
What are the outputs of photosynthesis? Glucose, oxygen gas
What are the inputs of aerobic cellular respiration? Glucose, oxygen gas
What are the outputs of aerobic cellular respiration? Carbon dioxide, water and ATP

3. Inputs & Outputs 6CO2 + 6H2O + sunlight  C6H12O6 + 6O2
Inputs/Reactants
Outputs/Products

4. Relationships between the amounts of reactants and products
6CO2 + 6H2O + sunlight  1C6H12O6 + 6O2
The numbers in front of the molecules are called coefficients. They represent the amount or number of molecules needed or produced in a reaction.
For example:
6 molecules of carbon dioxide produces 1 molecule of glucose.
6 molecules of carbon dioxide reacts with 6 molecules of water.
In order to produce 6 molecules of glucose, the reaction would need 36 (6x6) molecules of carbon dioxide.

5. Reminders Check your bean plants.
3rd Quarter ends on next Tuesday. April 9, I will close my grades on Sunday, April 7, 2019!

6. Objective
Students will answer unit 2 review questions to prepare for tomorrow’s unit 2 assessment.

7. Unit 2 Assessment Review
Use your time wisely!
Unit 2 Assessment Review
Work in collaborative groups to answer each review question.
You cannot write on the review. Put ALL of your answers on notebook paper.
