*Twenty Vocab flashcards:
 **Remember Titles and labels!
 Use one sheet of blank paper, folded into six squares,
for each six words.
 On the front AND back, upper right-hand corner,
begin numbering 1 through 20 (if the front is ‘1’, the
back is also ‘1’).
 This mean you will need 3 pieces of paper and two
additional squares. Partner with other people for the
two additional squares.
 On the front of each, write the word.
 On the back of each, write YOUR OWN definition, not
one from the glossary.
 You must have at least five words that include a
model as part of the definition.
 Make an Game Blank on ½ of a plain piece of paper:
o Number 1-20 on the left-hand side.
Photosynthesis/Respiration Model Lab
Materials: Green construction paper (leaf) folded in half
hamburger, one strip of green construction paper, another
color of construction paper (animal) also folded hamburger,
scissors, labels and structures model page, 1 baggie.
Methods: Cut out the labels and structures. As we view videos
and discuss the energy topics, place the appropriate cell
organelle in the correct organism structure. For example, if we
are doing photosynthesis, the green construction paper
represents a plant (organism) leaf (structure), and you would
place the correct organelle and labels inside the leaf. You
will practice doing this every day as we progress through the
various energy processes. This will be your quiz activity and
part of your unit test grade as well. So, be sure to keep your
parts, labels, leaf, and animal cell with you. If you lose pieces or
labels, remake them. You will need them on quiz and test day.

Cellular Respiration Lab
Background:
Cellular respiration is the process whereby cells metabolize
food into ATP energy. The most energy is produced during
aerobic respiration and the least amount of ATP energy is
produced during anaerobic respiration, or fermentation.
During respiration, food molecules in the form of glucose, a sixcarbon molecule, are rearranged while going through a series
of processes. Glycolysis splits the glucose into two pyruvic
acids and releases ATP. The pyruvic acids then go through the
Krebs cycle, further rearranging the carbons and releasing ATP
and carbon dioxide. The carbon molecules then go through the
electron transport chain producing ATP’s, where Oxygen is the
final electron acceptor, which combines with Hydrogen to
produce and release water.
Several ways of measuring cellular respiration include
measuring carbon dioxide release, oxygen intake, or the
amount of glucose consumed. Indirectly, we may compare
breathing (intake of Oxygen) during different environmental
conditions to roughly compare the amount of Oxygen available
at the cellular level.
Procedure:
You and your lab partner will be observing one goldfish
‘gulping’ at differing temperature settings. Make a data chart.
1.

5.
6.
7.
Obtain one small beaker and one large beaker.
Fill the small beaker about half-way with distilled water.
Use the net to obtain one goldfish.
Add the goldfish to the small beaker.
Record the initial temperature of the goldfish water.
Make a model of your setup.
To the large beaker, add about 1/3 tap water.
8. Place the goldfish beaker inside the large beaker.
9. Manipulate the water temperature by adding ice or heat
to the larger beaker; depending upon which lab bench
you are assigned.
10.
One partner will check the temperature every 30
seconds to maintain a constant temperature by using ice
or heat, depending on your bench assignment.
11.
The other partner will record the number of
‘gulping’ actions the goldfish takes during that 30-second
period.
12.
Remove the beakers from ice/heat if the
temperature changes more than 3o C.
13.
Record for a total of three minutes.
14.
Post your results on the overhead.
15.
Complete your data chart by recording other groups’
results.
16.
Make a line graph of the results.
Discussion:
1. Explain the relationship between temperature and
‘gulping’. Use concepts from the Chem unit, and your data
chart and graph as examples.
2. What do you think would happen to cellular respiration
if: the temperature were increased by 10o C? Why?
Decreased by 10o C? Why?
