1. 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
2. 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
Notes on cell respiration
3. Why do we need energy?
Heterotrophs and Autotrophs
The ability to do work
To live
To power functions in the cell
To do your homework (muscle fiber,
thinking)
To move
4. In what form is energy available?
Solar energy
Electric energy
Kinetic
Chemical
Potential
Nuclear
5. How does our body convert this
energy?
ENERGY MUST BE AS ATP
Adenosine Tri-phosphate
We do not eat ATP
The mitochondria makes it with
metabolism
What it takes in is called reactants
Products come out of a reaction
6. Where do the waste products go?
There are two waste products
#1- Carbon dioxide-exhaling
#2- Water-urinating, sweating, and
exhaling
8. Tuesday 18 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
9. 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
10. Lab Protocol
All bags/excess paper/etc must be off the
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)
Identify 3 similarities and 2 differences between cell respiration and burning food.
Calculate the number of calories in a Frito

12. If you’ve finished…
Part I (burning food) of the lab
◦ Complete the table on pg 1
◦ Write the analysis comparing and contrasting
burning food to cell respiration
Part II (measuring calories)
◦ Make sure all your data is filled in
Both parts of the lab
◦ Make sure all lab pieces are in the metal tray
◦ Start on the remainder of the analysis questions
Identify 3 similarities and 2 differences between cell respiration and burning food.
Calculate the number of calories in a Frito
13. Thursday 20 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.
HW:
• Reflections and conclusions questions
• Study for quiz
14. 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!
15. 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)
16. 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
17. Friday 21 October
Topic: Cell Respiration Review & Quiz
DO NOW:
• Get a clicker from the kidney table and review sheet
• 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!
18. 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
