Every reading assignment is expected to be completed BEFORE you come to class. Confused about the
reading? Prepare questions to ask in class AS YOU READ.
Be a Scout and Be Prepared…Reading quizzes may be given at ANY time.
Homework is due ON THE DUE DATE (Sectionals—Turn in on the due date…Field trips and
illnesses—turn in on your first day back.).
Do Now’s are to be completed in class and turned in THAT BLOCK. (Absent??—Turn in first day
back. Questions on the reading that goes with the Do Now??—Turn in written question specifying
what you don’t understand. Be specific. Don’t say, “I don’t get it”.)
Vocabulary understanding is necessary. Attend to the words at the beginning of each chapter, or words
that you encounter that are new to you.
6. **In order for you to participate in structured activities and labs, you must have
your Guided Reading up-to-date as well as your vocabulary.

*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 means 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 a 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. 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 for practice 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 six-carbon molecule, are rearranged while going through a series of
processes. Glycolysis splits the glucose into two pyruvic acids and releasing 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.

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.
Place the goldfish beaker inside the large beaker.
Manipulate the water temperature by adding ice or heat to the larger beaker,
depending upon which lab bench you are assigned.
One partner will check the temperature every 30 seconds to maintain a constant
temperature by using ice or heat.
The other partner will record the number of ‘gulping’ actions the goldfish takes
during that 30-second period.
Remove the beakers from ice/heat if the temperature changes more than 3o C.
Record for a total of three minutes.
Post your results on the overhead.
Complete your data chart by recording other groups’ results.
Make a line graph of the results.
Discussion:
1. Explain the relationship between temperature and ‘gulping’. Use terms from the
Chem unit, use data chart and graph as examples.
2. What do you think would happen to cellular respiration if: the temperature was
increased by 10o C? Why? Decreased by 10o C? Why?
