1. Matter and EnergyHow they interact with each other and the
environmentHow they move through the environment
2. Systems Basic Structure and how to apply to biological
concepts3. Structure & Function
How does the structure aid in the function?4. Change Over Time5. Behavior & Interactions
To understand Science you have to understand a few key themes

Formulas Must Be Memorized!!!!!
Photosynthesis:CO2 + H2O + Energy C6H12O6 + O2
Cellular Respiration:C6H12O6 + O2 CO2 + H2O + Energy
Matter and Energy you need to know for this unit

Where: Occurs in all cells (including plants and animals)
Structure: Specifically in mitochondria
Function: Converting Glucose into Energy
Chemical Formula:C6H12O6 + O2 CO2 + H2O + Energy

Aerobic means: “with oxygen”Oxygen is always need to ignite somethingRespiration is similar to burning a
marshmallow

Anaerobic means: “without oxygen”If not oxygen is present, respiration still
happens, but it is not as efficient (producing less energy).
