What I am expecting of YOU:
1. SILENT voices when I am
talking
2. YOUR focus
3. Engagement - this is the
last week we have to
review!
Biogeochemical Cycles - CARBON
● Carbon is the basis of life on
earth found in rocks,
oceans, atmosphere, and
living things
● CO2 in atmosphere → used
to make food by plants
● Humans and other animals
eat plants → carbon now in
our cells
● Plants and animals die →
carbon returned to earth
and atmosphere
Biogeochemical Cycles - NITROGEN
● Nitrogen is needed to make
proteins in living things
● Bacteria is ESSENTIAL to all
steps
● Bacteria take nitrogen from
atmosphere and make it
useable for plants
● Animals eat plants
● Animals and plants die
● Bacteria return the nitrogen
to the earth
Photosynthesis
● Plants use the energy
from sunlight to make
glucose.
● The reactants of
photosynthesis are sunlight,
carbon dioxide, and water.
● The products of
photosynthesis are oxygen
and glucose.
● The balanced chemical
equation:
Sunlight + 6 CO2 + 6
H2O → 6 O2 + C6H12O6
Cellular Respiration
● Breaks down glucose to
release Energy/ATP
● The reactants of cellular
respiration are oxygen and
glucose
● The products of cellular
respiration are carbon
dioxide, water, and ATP.
● The balanced chemical
equation:
6 O2 + C6H12O6 → 6
CO2 + 6 H2O + ATP
Human Health
The three molecules that serve as food for the
cell are proteins, carbohydrates, and lipids.
Food energy is measured in calories.
If one consumes more calories than the body uses,
then they will gain weight.
Human Health
A person who burns calories at a fast rate is said
to have a high metabolism.
Basal metabolic rate is the minimum number of
calories that a person needs to maintain bodily
functions while at rest.
The digestion of food provides the body with the
necessary reactants to perform cellular
respiration.
Tic-Tac-Toe
1. Determine who is X and who is O
2. I say definition/question 2 times...only...YOU talk, YOU miss it,
YOU lose
3. YOU or partner finds the right answer first wins
4. YOU or partner that makes tic-tac-toe first wins!
EXPECTATIONS
Voices = whisper voice
Remain seated
100% on task
