Monday 17 October
Topic: Cellular Respiration
DO NOW:
• Brainstorm everything that you can about energy.
Think about things such as where it comes from, how it
becomes available, how does it change into other forms,
what is it used for, what types there are, etc.
HW:
• 8-1 Reading for Understanding (complete classwork
from Friday – you will get your sheet back and a copy
of the reading)
Objective
By the end of this class, you will be able
to write the chemical equation for cell
respiration and identify its reactants and
products.
Agenda
Quick announcements
Notes on cell respiration
Why do we need energy?
To do work
To survive
To power ourselves
To make heat
To maintain homeostasis
OBJECTIVE – By the end of this class, you will be able to write the chemical equation for cell
respiration and identify its reactants and products.
In what form is energy available?
Kinetic Energy
Solar Energy
Potential Energy
Chemical Energy
Magnetic Energy
OBJECTIVE – By the end of this class, you will be able to write the chemical equation for cell
respiration and identify its reactants and products.
How does our body convert this
energy? WE MUST USE CHEMICAL ENERGY(ATP)
Adenosine tri-phopshate(we don’t eat ATP)
We make it by breathing and eating
Mitochondria converts reactants into usable
ATP (breathing in oxygen and eating
glucose)
OBJECTIVE – By the end of this class, you will be able to write the chemical equation for cell
respiration and identify its reactants and products.
Where do the waste products go?
There are 2 waste products( carbon
dioxide and water)
To exhale
Sweating, urination, and exhaling
OBJECTIVE – By the end of this class, you will be able to write the chemical equation for cell
respiration and identify its reactants and products.
THE FORMULA!!!
O2 + C6H12O6 CO2 + H2O + ATP + heat
OBJECTIVE – By the end of this class, you will be able to write the chemical equation for cell
respiration and identify its reactants and products.
Tuesday 18 October
Topic: Exercise, Cell Respiration, and
your body
DO NOW:
• Pick up a packet from the kidney table and complete the
front page (“pre-lab”). You should fill in the blanks and
write hypotheses for how exercise affects the body.
• Andre will come around and collect the 8-1 reading hw
quickly and quietly
HW:
• Reflections and conclusions questions
Objective
Explain how the chemical equation for
cell respiration relates to breathing, and
why we breathe harder during exercise.
Agenda
Protocol for outdoor activity
How to measure a pulse
Outside activity!
Pulse & Breathing rate
Everyone focus for a few seconds and
note if your breathing is slow, medium, or
fast (compared to how you normally
breathe)
Next, find your pulse on your neck or
your wrist and we will measure it for 15
seconds
◦ Multiply this number by 4 to get beats/min
(bpm)
Before going outside…
You only need to bring your lab and a pencil
and can leave everything else here
We go out the back stairs, out the door, and
around to the crosswalk
Line up with your partner along the edge of
the basketball court by the red stairs
Once everyone completes the activity, listen
for me to say “Now” and “End” which will be
the timed minute for pulse
Swap with your partner
Now…
Take a seat, chill, start quietly writing your
answers
Wednesday 19 October
Topic: Measuring energy in food
DO NOW:
• Pick up a lab packet from the kidney table and
complete the pre-lab assignment
HW:
• Post-lab analysis questions
Objective
Identify 3 similarities and 2 differences
between cell respiration and burning food.
Calculate the number of calories in a Frito
Agenda
Lab protocol
Demo of burning food
Labs part 1 & II
Lab Protocol
All bags/excess paper/etc must be off lab tables
Any hair long enough is to be tied back
During the burning portion, absolutely no
getting up for anything (wait until after this
portion of the lab is complete)
Nothing is going near the flame!
Identify 3 similarities and 2 differences between cell respiration and burning food.
Calculate the number of calories in a Frito
Friday 21 October
Topic: Cell Respiration Review & Quiz
DO NOW:
• Get a clicker from the kidney table
• Take out your notes on cell respiration
HW:
• Read 38-1 and take notes in your notebook
• Think of a food/meal that contains carbohydrates, lipids
(fats), and proteins. Write it down after your reading
notes!
Objective
By the end of this class, you will be able
to apply knowledge of cellular respiration
to answer short-answer and open-
response questions on the quiz

Question 10
Exercise Lab Review Why does breathing rate increase during
exercise (2 reasons)?
◦ Necessity of oxygen
◦ Releasing carbon dioxide
Why does heart rate increase during exercise?
◦ Blood carries the stuff for cell respiration (reactants & products)
Does the amount of cell respiration increase during exercise? Why or why not?
◦ Yes! Cell respiration increases because you need more energy.
SIMILARITIES:
• both require
oxygen
• both require
glucose
• both contain heat
• both convert one
form of energy to
another
DIFFERENCES:
• cell respiration also
makes ATP energy
• also makes water
• Carbon monoxide
Burning food lab
Burning food lab
What was the source of energy in the
Frito? (i.e. what fueled the fire)
If the Frito was not consumed by fire,
what would happen to it if it was eaten?
How would you summarize the two
reactions in terms of energy conversion?
IF you finish early:
◦ Take a text from the cabinet, go to the back,
and start reading 38-1 (hw) and taking notes
in your notebook
