Monday 17 October Topic: Cellular RespirationDO NOW:• Brainstorm everything that you can about energy.Think about things such as where it comes from, how itbecomes 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 classworkfrom Friday – you will get your sheet back and a copyof 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 homeostasisOBJECTIVE – By the end of this class, you will be able to write the chemical equation for cellrespiration and identify its reactants and products.
In what form is energy available? Kinetic Energy Solar Energy Potential Energy Chemical Energy Magnetic EnergyOBJECTIVE – By the end of this class, you will be able to write the chemical equation for cellrespiration 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 cellrespiration 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 exhalingOBJECTIVE – By the end of this class, you will be able to write the chemical equation for cellrespiration and identify its reactants and products.
THE FORMULA!!! O2 + C6H12O6 CO2 + H2O + ATP + heatOBJECTIVE – By the end of this class, you will be able to write the chemical equation for cellrespiration and identify its reactants and products.
Tuesday 18 OctoberTopic: Exercise, Cell Respiration, andyour bodyDO NOW:• Pick up a packet from the kidney table and complete thefront page (“pre-lab”). You should fill in the blanks andwrite hypotheses for how exercise affects the body.• Andre will come around and collect the 8-1 reading hwquickly and quietlyHW:• 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 foodDO NOW:• Pick up a lab packet from the kidney table andcomplete the pre-lab assignmentHW:• Post-lab analysis questions
Objective Identify 3 similarities and 2 differences between cell respiration and burning food. Calculate the number of calories in a FritoAgenda 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 OctoberTopic: Cell Respiration Review & QuizDO NOW:• Get a clicker from the kidney table• Take out your notes on cell respirationHW:• 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 readingnotes!
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 quizAgenda Cell respiration review Lab review (exercise and burning food) Quiz

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.
Burning food labSIMILARITIES: DIFFERENCES:• both require • cell respiration also oxygen makes ATP energy• both require • also makes water glucose • Carbon monoxide• both contain heat• both convert one form of energy to another
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
