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 (complete classwork
from Friday – you will get your sheet back and a copy
of the reading)

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
 Quick announcements
 Notes on cell respiration

3. 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.

4. 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.

5. 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.

6. Where do the waste products go?

respiration and identify its reactants and products.

7. 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.

8. 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

9. 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!

10. 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)

11. 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

12. Now…
 Take a seat, chill, start quietly writing your
answers 

13. 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

14. Objective
 Identify 3 similarities and 2 differences
between cell respiration and burning food.
 Calculate the number of calories in a Frito
Agenda
 Lab protocol

 Labs part 1 & II

15. 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.

(fats), and proteins. Write it down after your reading
notes!
