Biology Cell analogy project: DUe 11/17-18/2014
Cell Analogy Group/Individual Project:
500pts
Task:
You are to
look at the internal structure and function of a cell and create an illustrated
diagram, t-chart, web page, power point, story or other teacher approved
project format that compares the cell and its’ organelles to an analogous
system such as a school, a car, a factory or whatever; each of which have
important smaller parts with important functions.
Your project needs to include each organelle listed below and its role in the cell and it will need an analogous system to the cell and each organelle. Make sure you compare and explain the roles of each organelle and their analogous counterparts.
Your project needs to include each organelle listed below and its role in the cell and it will need an analogous system to the cell and each organelle. Make sure you compare and explain the roles of each organelle and their analogous counterparts.
Ex: Cell =
School, where the nucleus, which controls all cell functions, could be compared
to the principal in the school. If you
use this example I will not give you higher than a 3 on #3 of the rubric.
Use the
text book, Internet, notes and your brains
Grading (subjective rubric = score of 5-0
points based on my feelings about the quality and evident effort on the project
and its’ parts)
Grade categories
- Cell organelles/structures and function
- Include: cell membrane, cytoskeleton, nucleus, ribosome, endoplasmic reticulum, golgi apparatus, lysosomes, vacuole and mitochondria. Bonus points: for doing a plant cell (cell wall and chloroplast) = 30pts; Include flagella or cilia = 15pts
!!!No analogous structures = no Bonus
Points!!!
- Analogous system with corresponding features for each organelle/structure and function
- Quality (color, creativity, attention to detail…)

Biology- Biochemistry Quest Tuesday/Wednesday 10/28 + 29
400 pt. quiz/test on material from Ch 6 in Glencoe biology text book: elements, compounds, chemical/physical changes, enzymes, properties of water, acid/base/ph , bio-molecules
Earth science Volume of a drop guide sheet
Instructions: DO
NOT WRITE ON THIS HAND OUT! You and your group will be practicing the steps of the scientific method, conducting an
experiment and writing-up a lab.
·
On
a separate sheet of paper write the names of the members of your table that actively
help with all parts of the mini-lab; this will be your lab write-up.
·
Write
out the question I gave you below, include the label Question:
·
Write
our Hypothesis: and then your
educated guess to answer the question.
Remember to discuss with your tablemates about how to make an educated
guess then record the hypothesis on your lab write-up.
·
Continue
writing the label for each step (Q, H,
T, M, P, D, A, & C) and following my hints for each step.
Question: How much space (volume) does a drop of water take
up?
Hypothesis: What is
your educated guess to answer the question? Compare 1 drop to 1 mL of water.
Materials: Every
item used for data collection
Procedures: Step by step directions of your experiment
that include diagrams that help
illustrate your procedures
Data table: Have
room to include ten trials, Yes, do the experiment ten times, make sure
everyone in your group has an opportunity to collect data by doing the
experiment.
Analysis: Show an example of
how calculated the volume of a drop, in mL. Also show an example of how
calculated the average volume of a drop, in mL, for the trials you did. Create
a data table and Bar graph showing the average drop # for all other groups in
the class.
Conclusion: Restate your hypothesis. Did you answer the
question?
How do your results compare
to the other tables? Explain.
How
might error have occurred in your experiment?
What affect might it have had? How
can you redo your experiment to attain more accurate
results?
Bonus Points: if you finish both mini-labs early, you may
earn bonus points for conducting a next step to this experiment. You are limited to the materials provided or
on your person. You may also include a
graph(s) of your data for e.c.
Bonus Points: if you finish both
mini-labs early, you may earn bonus points for applying your data from this lab
to the drops on a penny lab to find the ave. volume of the bubble of water that
formed on the penny. Explain what you did and show the calculation.

earth science ; Drops on a penny lab
Drops
of Water: Measurement and Error
Instructions: DO
NOT WRITE ON THIS HAND OUT! You and your group
mates will be practicing the steps of the scientific method, conducting an
experiment and writing-up a lab.
·
On
a separate sheet of paper (NOT in the notebook) write the names of the members
of your table that actively help with all parts of the mini-lab; this will be
your lab write-up.
·
Write
out the question given to you below, include the label Question:
·
Write
out Hypothesis: and then your
educated answer to answer the question.
Remember to discuss with your tablemates about how to make an educated
guess then record the hypothesis on your lab write-up.
·
Continue
writing the label for each step (Q, H,
M, P, D & C) and following the hints for each step.
Question: How many drops of water can a penny hold?
Hypothesis: What is
your educated guess to answer the question?
You may compare a penny next to a single drop to help you with this.
Materials: Record every
item used for data collection
Procedures: Record Step by step directions of how you
used each material listed in your experiment to find your answer, include
diagrams that help illustrate complex procedures. Final procedures should be
more complex than those listed in your RD.
Data table: Have
room to include fifteen+ trials of data collection. Yes, do the experiment at least fifteen
times, (5 trails per person) make sure everyone in your group has an
opportunity to collect data by doing the experiment.
Analysis: What is your average number of drops? Show an example of how you calculated the
average # of drops for the trials you
did. Create a data table showing the average drop # for your group. Make a bar
graph of your trails and the average # of drops.
Conclusion: This
should be in paragraph form and not just answers to the following questions
Prompts: Did you answer the question? Do your results compare to the other
tables? Explain. How might error have occurred in your
experiment? How can you redo your
experiment to attain more accurate results?
Bonus Points: if you finish early, you may earn bonus
points for conducting a next step to this experiment. You are limited to the materials provided on
your person & you must make another lab write up. You may also include a graph of your data for
e.c.
Enzymatic Browning mini lab Analysis Questions
1) how did each treatment affect the chemical reaction that occured on the fruit's soft tissue? Why were some of the treatments more succesful than others?
2) A restaurant owner wishes to serve fresh cut fruit. What factors might be considered in choosing a recipe for the preparation of the fruit??
