Unit 5: Guiding Questions
 How do plants make food for
themselves?

organisms need oxygen?
Today’s SPI & Objectives
 SPI 3210.3.2 Distinguish between aerobic
and anaerobic respiration.
 SWBAT summarize the overall process

aerobic respiration is used to provide
energy in a given situation

Boom Bag
 With a partner or 2 partners
 Slips of paper: Question on the front and answer on the
back
 Partner A removes a slip and asks Partner B the question
while HIDING the answer.
 If Partner B gets the question correct, they may keep the slip
of paper. This counts as a point.
 The partner with the most points wins!
 Catch: If Partner A pulls a slip with “BOOM”, Partner B loses
all their points and must put all their slips back into the bag.
Reminder
 Lab tomorrow!
 Check Google calendar for updates,
reminders, and lessons.

Cellular Respiration Quiz
Announcements
 Cellular Respiration quiz tomorrow
Purpose/Background: 2 mins


Purpose:
To determine the effect of exercise on the rate of cellular respiration.


Background:

Cellular respiration is an aerobic process that involves the breakdown of glucose to release usable
energy for the cell. This process occurs in the mitochondria of most eukaryotic cells. The overall
equation of cellular respiration is as follows:
 The waste products of cellular respiration are carbon dioxide (CO2) and water (H2O). Carbon
dioxide is a gas that is released from the cells and the body during exhalation. When carbon
dioxide is combined with water, it forms carbonic acid (H2CO3).
 In this lab, you will form carbonic acid by bubbling your breath through water. You’ll then test for
the presence of carbonic acid with the indicator, phenolphthalein. This indicator is pink in the
presence of a base, such as sodium hydroxide (NaOH), and clear in the presence of an acid,
such as carbonic acid (H2CO3). By recording the time it takes to neutralize a basic solution with
your breath, one can determine the relative amount of carbon dioxide being exhaled. This
also indicates the relative rate at which cellular respiration is occurring in the body.
Pre-Lab Questions: 5 minutes
 What are the waste products of cellular
respiration?_______________ & ______________
 What does carbon dioxide become when mixed with
water?______________ ___________
 What color is phenolphthalein in the presence of a
base?________________
 What color is phenolphthalein in the presence of an acid
(CO2 and Water)?_______________
 How can phenolphthalein be used to determine the rate at
which cellular respiration is occurring in the
body?___________________________________________
________
Hypothesis
 Hypothesis Form
Procedure: 13 minutes

Pour 75 ml of distilled water into a 250 ml flask.

Add 5 drops of phenolphthalein to the water.

If the water turns pink, there is no CO2 present and you may move on to step 5.

If the water remains clear, you must neutralize the CO2 that is present by adding NaOH.

Add the NaOH drop by drop and swirl the water to see if the pink color remains. Add 3 drops of NaOH so that the water in your flask stays a deep pink color. MS.
MITCHELL WILL ASSIST YOU WITH THIS STEP.

Starting with a DEEP PINK solution now, sit very quietly for two minutes without moving.

Place the end of a soda straw into the deep pink solution you’ve prepared. Breathe in deeply and start timing when you slowly exhale through the straw into the
solution. Continue to exhale (plug your nose so you don’t sneak any breaths) until the solution is no longer pink. (This is your control group.)

Record the time it took for the color change in your observation table.

Prepare a new water sample as you did before, adding the same 3 drops of NaOH. Solution should be deep pink.

Exercise for one minutes by walking, running, or jumping in place. Following the same procedure, start timing as you EXHALE your breathe into the solution
until it is no longer pink.

Record the time it took for the color change in the observation table.
