CASE FOCUS
In this case, students travel back in time to the 1600‟s and explore the development and initial
advances in cell theory. The case starts with a newspaper article documenting Robert Hooke‟s
discovery of “cells” using a rudimentary microscope and cork tissue. Students are then presented
with the first disclosure that situates them as part of a team in a Dutch laboratory where Antoine
Van Leeuwenhoek has started working with a compound microscope. Students will design and
execute an experiment that will advance cell theory using pond water and onion cells. An
introductory microscope laboratory experiment is provided as part of the case.

It is just outside Amsterdam, Holland, in the year 1672. Your apprentice team in Antoine Van
Leeunenhoek‟s workshop has had an interest in the workings of lenses for quite some time. Hooke‟s
article has caught the attention of your employer, Van Leeuwenhoek, and he would like to explore this
cell theory.
Van Leeuwenhoek‟s latest achievement is the compound lens microscope. His tinkering with glass
processing has led to the development of lenses for microscopes. These lenses bend light to create a
magnified image. With this microscope, Van Leeuwenhoek postulates the team can advance Hooke‟s
findings
Van Leeuwenhoek has charged the team with using this technology to design and execute an experiment
that will build upon Hooke‟s findings and show that organisms are made up of living cells. Your team
will be using onion cells and pond water and will need a strong hypothesis statement to be tested. Van
Leeuwenhoek is known for strictly adhering to the scientific method in all his experiments.

Success. Using advances in technology, your team has been able to further contribute to the cell theory.
Your responsibility as a scientist doesn‟t stop with the experiment...its time to share the finding within the
science community and general public. Van Leeuwenhoek‟s lab has been asked to submit scientific
abstract outlining why the experiment took place, methods and materials used, results and conclusions.
Be sure to briefly mention what future experiments may be carried out to advance the cell theory. The
abstract should be no more than 500 words. The lab team will also need to prepare a poster presentation
with a scale drawing of findings and be able to describe the experiment and hypothesis tested.
Use your crystal ball to look into the future and explain how the Canadian Light Source Synchrotron at
the University of Saskatchewan uses advances in light technology and what types of research are carried
out there.
LABORATORY INVESTIGATION
HOW TO USE A MICROSCOPE
Pre-Lab Discussion
As you explore the natural world in biology labs, you will be doing something you do every day
– making observations. You use your
senses to make observations, but
sometimes your senses need help. For
work in biology the microscope is the basic
tool to examine organisms and objects
that are too small to be seen with the
unaided eye. Refer to the Figure 1
throughout this lab and other labs that use
a microscope.
Microscopic Observations
When you view an object through a
microscope, you place the object on a
glass slide. The slide may be either a drymount or a wet-mount slide.
In a dry-mount slide, the object to be
examined is placed on the slide and
covered with a small square of plastic
covered a coverslip.
In a wet-mount slide, a drop of liquid is
placed over the object before being
covered with a coverslip.
1. When you carry a microscope, why should you carry it with one hand on the arm of the
microscope and the other hand under the base?
___________________________________________________________________________

2. Why should you hold a microscope slide by its edges?
___________________________________________________________________________
___________________________________________________________________________
___________________________
Problem
How do you prepare an object to be viewed under the microscope, and how do you use the
microscope to observe the object?
Materials (per group)
Microscope
Microscope slide
Coverslip
Newspaper
Scissors
Dropper
Water
Forceps
Paper towel
Pond water sample
Onion
Methylene Blue stain
Clear plastic ruler
Safety
Wipe up any spills immediately.
Handle slides with care to avoid breakages. Tell the teacher if a slide breaks and dispose of the
broken slide properly.
If your microscope has a mirror, do not tilt it directly toward the sun. Eye damage can occur if
direct sunlight is used as a light source.
Wet Mounts
Wet mounts are temporary slides that you prepare yourself. When doing a wet mount follow
the procedure outlined below:
 Place the specimen (mixed culture, tissue, etc.) on the center of a clean slide.
 Add a drop of water or designated stain if required. (Note: liquid cultures do not require
adding water)
 Place one edge of the cover slip on the slide near the specimen (This is done by holding
the cover slide at a 45ºangle). Gently lower the cover slip on top of the specimen. Try to
avoid trapping air bubbles.


Blot an excess fluid with lens paper before you place the slide on the stage of the
microscope.
After you have made your observations the slide & cover slip should be washed, dried &
replaced in their appropriate locations.
Procedure
Exercise 1:
PROPERTIES OF THE MICROSCOPE
1. Cut a small letter “d” from the newspaper and place it in the center of a clean
microscope slide so that it is in the normal reading position.
2. Using the dropper, carefully place a small drop of water over the letter.
3. Place one side of a clean coverslip at the end of the drop of water at a 45° angle.
Carefully lower the coverslip over the letter “d” and the drop of water. Do NOT press on
the coverslip. It should rest on top of the water. Try not to trap any air bubbles under
the coverslip because these will interfere with your view of the specimen. If you have
trapped air bubbles, make a new wet-mount slide.
4. Absorb excess water by touching a folded piece of paper towel to the water that comes
out around the edges of the coverslip.
5. In Observations, draw a picture of the letter “d” just as you see it on the slide, without
the aid of the microscope.
6. Turn the nosepiece so that the low-power objective, often called the ‘scanning
objective,’ is facing downward, toward the stage.
7. Place the slide under the clips on the stage of the microscope. Position the slide so that
the letter “d” is directly over the center of the stage opening.
8. Use the coarse-adjustment knob to slowly lower the low-power objective until it almost
touches the slide. CAUTION: To prevent damage to the microscope and the slide, do not
let the lens actually touch the slide.
9. Tilt the mirror or adjust the light and adjust the diaphragm until you get the best light
for viewing the specimen. CAUTION: Do not aim the mirror at direct sunlight.
10. Looking through the eyepiece, use the coarse-adjustment knob to slowly raise the lens
until the letter comes into view. CAUTION: To prevent damage, do not lower the coarse
adjustment while looking through the eyepiece.
11. Look at the objectives and the eyepiece of your microscope. Then answer question 1 in
observations.
12. Find the total magnification power of your microscope by multiplying the magnification
of the eyepiece lens by the magnification of the objective lens you are using. Then
answer questions 2 and 3 in Observations.
13. In Observations, draw a picture of the letter “d” as viewed through the microscope.
Record the magnification you are using.
14. While looking through the eyepiece, move the slide to the left. Notice which way the
letter seems to move. Now move the slide to the right. Again notice which way the
letter seems to move. Then answer questions 4 and 5 in Observations.
15. Switch to the high-power objective lens by revolving the nosepiece so that the highpower lens clicks into place. CAUTION: The high-power objective is longer than the lowpower objective; it may easily touch and damage the slide. Look at the side of the
microscope when switching to the high-power objective to make sure it clears the slide.
Using the fine-adjustment knob only, bring the specimen into focus.
16. In Observations, draw a picture of the letter “d” as seen with the high-power objective
lens. Record the magnification you are using.
17. Switch to the low-power objective lens by revolving the nosepiece. It is now safe to
remove the slide from the stage. Remember to always have the low-power objective
over the stage when putting on new slides or removing slide.
18. Clean slide and coverslip to prepare for use for the next exercises.
Exercise 2:
MEASURING WITH A MICROSCOPE
It is important to be able to determine the size of the specimens that you observe with the
microscope.
1. Use a clear ruler to determine the diameter of the viewing field under the low-power
objective. Position the ruler so that the millimetre marks are visible in your viewing
field. Remember that there are 1000 micrometers (µm) in a millimetre.
2. In Observations, record the estimated length (diameter) of your viewing field in the
chart provided.
3. You can use the ruler to determine the diameter of the viewing field under the mediumpower objective. Record the size of the viewing field in the Observation section.
4. You can determine the diameter under medium power using a mathematical proportion
method to determine the diameter.
Medium power field diameter = low power field diameter X low
power magnification/medium power magnification
Record the size in the chart under the calculated diameter, in the Observation section.
5. You cannot use the ruler method to determine the diameter under high power; you
must use the mathematical proportion method.
High power field diameter = low power field diameter X low
power magnification/high power magnification
Record the size in the chart under the calculated diameter, in the Observation section.
Exercise 3:
PROTISTS
These are the ‘wee beasties’ that Von Leewenhoek observed in his early microscope. They live
in common pond water.
1. Obtain a sample of a protist from one of the containers at the front of the room. The
specimens usually come from the bottom and probably will contain chunks of algae or
other debris that you can see with your naked eye. (Be careful that your slide isn’t too
thick) The instructor will help you obtain this sample.
2. Place a drop containing one or more protists on a slide and cover with a cover slip.
3. Scan the slide for organisms: Start at the upper left-hand corner, and move the slide
forward and back as you work across the slide from left to right.
4. Experiment by using all available lenses (NOT the oil immersion!), by focusing up and
down with the fine-adjustment knob, and by adjusting the light so that it is not too
bright.
5. In Observations, draw any organisms you see and label your drawings.
Exercise 4:
PLANT CELLS
1. With a scalpel or your fingers, strip a thin, transparent layer of cells from a piece of
onion.
2. Place it gently on a clean, dry slide.
3. Add a drop of methylene blue stain and cover with a coverslip.
4. Observe under the microscope and draw what you see in the Observation section. Be
sure to label your drawing.
5. Locate the cell wall. Is a nucleus visible?
6. Under high power count and record the number of cells across the diameter of the high
power field, both lengthwise and side to side. Record your numbers in the space
provided in the Observation section.
7. Using the number you calculated in exercise 2 for the high power field of view, calculate
and record the length and width of an onion cell in micrometers.

Drawing Specimens
1. Use PENCIL – you can erase and
shade areas.
2. All drawings should include clear
and proper labels (and be large
enough to view details).
Drawings should be labelled with
the specimen name and
magnification.
3. Labels should be written on the
outside of the circle. The circle
indicates the viewing field as seen
through the eyepiece, specimens
should be drawn to scale – ie..if
your specimen takes up the whole
viewing field, make sure your
drawing reflects that.

DISCLOSURE 2
You are fortunate to know a local ecologist; you decide to consult with him. He
suggests that you begin by studying forest and grassland dominated ecosystems.
Look at the structure and diversity of plants.
Ecological niches can provide lots of information. How are they structured and
how have they adapted to their conditions? Indigenous knowledge may also
provide some insight.
DISCLOSURE 3
Natural disturbances are a normal force within the environment. Identify the
disturbances that may influence the grassland and forest ecosystems. What are the
results of these influences? It is recommended that you look at natural patterns of
succession.
DISCLOSURE 4
Plant and animal species develop adaptations in response to pressures and threats
within their ecosystems. This provides them with a means of survival, which may
be distinguished as resistance or as resilience.
Evidence of this behaviour can be identified through the K species and R species
that are exclusive to the environment in which pressures and threats are apparent.
Examine these concepts.
DISCLOSURE 5
A closed system self-regulates gains and losses of energy and natural ecosystems
resemble a closed system with respect to energy and nutrient cycles.
To best understand the concept of energy flow, it is recommended that you
investigate nutrient cycling.
Limit your efforts to Nitrogen, Carbon and water cycles; know the chemical forms
and the specific components of the chemical reactions in the cycles.
Identify where gains and losses occur.
DISCLOSURE 6
Your most recent conversation with your ecologist draws your attention to an
agricultural monocrop ecosystem. How do the different ecosystems compare?
How do niches differ and how can you apply ecological principles that you learned
from natural ecosystems to a system that is managed and lacks the structure and
diversity that is found in nature?
DISCLOSURE 7
Disturbances also occur in managed ecosystems; are they the same as in a natural
ecosystem? Identify all influences in agriculture production.
How is succession demonstrated and in what ways does a production ecosystem
differ from a natural ecosystem in terms of how plant species respond to pressures
and threats?
How do resistance and resilience compare and what influences are present that do
not have an influence in a natural ecosystem?
DISCLOSURE 8
Nutrient cycles are an important factor in sustaining a monocrop ecosystem.
Apply what you know about nutrient cycles; identify where gains and losses occur
and what influences these.
How do the different ecosystems compare? Based on what you have discovered
throughout the case, your presentation should outline how you can incorporate
ecological principles seen in natural ecosystems into a production system in efforts
to increase sustainability.

DISCLOSURE 1
A newspaper article dated June 20, 2007 reported a cougar sighting along the east
bank of the South Saskatchewan River. This caused a lot of concern considering
that many people use the area AND cougars are known to attack humans,
sometimes with fatal results.
Your team of Conservation Officers has been presented with this news article
along with a request that you determine the cause of this problem and propose a
humane solution. It is worthwhile to begin by investigating the natural behaviours
of cougars and the habitats in which they live.

DISCLOSURE 2
When investigating the behaviours and habitat of cougars, articles on local and
provincial history of cougars in Saskatchewan may be useful.
Have you considered breeding, diet, territory size and boundaries, natural
dispersion and movement patterns, seasonal activity, and history of cougar attacks?
7
DISCLOSURE 3
The behaviour of cougars is dependent on various relationships and factors within
its environment. In order for a successful solution to be determined, these
relationships and factors need to be identified and well-understood.
8
DISCLOSURE 4
As you investigate the relationships that exist, account for food supply, carrying
capacity, population density, and population fluctuations. Examine the impact of
interspecific and intraspecific competition, and urban encroachment.
Graphs and charts are a means to visualize wildlife populations. Be sure to include
graphic models of cougar and prey populations over time.
9
DISCLOSURE 5
Apply concepts of cause and effect. What are density dependent factors and
density-independent factors that influence the cougars‟ behaviour and pressures
them to venture into urban environments. Contemplate natural fluctuations, the
health of the cougars, climate, and weather. Is there an indicator species from
which you can gather information?
10
DISCLOSURE 6
As you resolve the problem of cougars entering urban areas, you should include a
long-term assessment plan. The goal of the assessment plan is to ensure that your
proposed solution causes minimal to no disruption to the natural cycles in
Saskatoon and the surrounding ecosystem. What are some options you can use to
examine populations in the environment? Differentiate between biased and
unbiased sampling techniques, and identify the advantages and disadvantages of
each to ensure that your plan is effective. Include with this a statement regarding
the duration of your assessment plan.
11
DISCLOSURE 7
Your team will present at a town meeting. You will explain your reason for
increased cougar sightings, a strategic management plan, what the public can
expect, and how can they be better prepared. Following the presentation, each
team member will submit an individual report.

Meet the Problem
A farmer who owns and operates a deer farm recently found some dead deer.
Some deer are still alive but are showing signs of illness. The symptoms exhibited
by the remaining live animals include poor coordination, paralysis, isolation from
the herd, emaciation, and excess salivation. The farmer‟s first response was to call
the local vet. This is where you come in - you and your colleagues are
veterinarians. Although you have yet to diagnose the illness and determine the
cause, based on the symptoms presented, you identify this as a reportable illness
and send brain tissue to Prairie Diagnostic Services for analysis and you contact
the Canadian Food Inspection Agency.
This has never happened to this farmer before so he has many questions. As a
courtesy to him and other local farmers, you will provide answers to the questions
that arise from this incident. Following protocol of the clinic in which you work,
you are required to file a detailed report.
As you proceed through this case, keep detailed notes so you can submit a
complete report by the time this case is closed.

Disclosure 1
With the results in hand, your team knows to focus on a disease that is caused by
an infectious agent, of which the farmer would like to know the identity. He also
wants to know exactly what an infectious agent is!
In preparing your response, consider agents that typically cause disease – limit
yourself to bacteria and viruses. Consider physical structure, mode of transmission
and action as well as the mechanism of treatment. How are we able to control
diseases, and how do some remain out of our control? This information will be
included in your case report.
21
Disclosure 2
The picture is becoming much more clear now. As you continue to investigate the
circumstances of the illness, you have determined the disease is a spongiform
encephalopathy.
(“Spongy what?” the farmer asks!) It looks like you need to find out more about
encephalitic diseases. In your investigations, consider more than just cervids –
which other animals can be affected (and humans are animals, too!) and what are
the names of other encephalitic diseases?
For a complete report, provide a timeline for encephalitic diseases with the
information you gather. Be sure to indicate where species barriers are crossed
(should people be worried?) and what happens when humans influence population
densities before a host has adapted to an infectious agent.
22
Disclosure 3
As you continue to collect information, you have probably determined that Chronic
Wasting Disease is caused by neither bacteria nor viruses, but prions. Prions?!
There are so many questions to answer!
The farmer asks, “What is a prion?”
Good question! If it is not a bacterium that can self-replicate or a virus that only
needs host DNA to replicate, then what is a prion?
Turn your attention to a determining exactly what a prion is. How does the
structure and activity of a prion make it virulent and why does this concern us?
What is the immunological research to prion diseases in terms of curing and
controlling the disease - have you considered that this may have been around for a
long time? This information will be a part of your report, along with the timeline
you are preparing. Have a close look at prions in order to present a clear and
detailed answer to the farmer‟s question.
23
Disclosure 4
It is beneficial to look at the big picture of prion diseases. Perhaps you have
already identified animal feed as a possible means of introducing the agent into a
healthy herd. Rather than centralizing your information on the present situation,
consider the repercussions of diseases that cross species barriers. This includes
aspects such as epidemics, pandemics, food safety, and trade relationships.
24
Disclosure 5
You may find it interesting to know that Canada has a top quality food safety
program (something we may even take for granted!). Is research in Canada
keeping up with problems that arise from prion diseases? There must be some
credibility to standard testing procedures as well as tests that are more sensitive in
indicating a positive result for a prion disease.
If Canadian scientists are successful in developing research tools that are more
effective, what could happen, especially if countries that trade with Canada are not
as advanced (think: does cheap food = safe food)? Explain the possibility of a
balance between positive trade relationships and biosecurity.
When preparing your report for this part of the case, think long term…many years
from now, even decades.
25
Disclosure 6
Focus your attention back to the situation at hand. What happens when a
reportable disease is suspected in a managed animal herd and subsequently
confirmed? You have already identified that it is critical to prevent this disease
from spreading. What will you advise the farmer to do next?
For future illnesses such as this one, identify what would you expect should this
same situation present itself again? Start from the initial phone call - what
sequence of events would occur and which agencies are involved.
Your final report (prepared individually) should include everything the disclosures
have guided including your advice to the farmer regarding the future of his animals
and the best options for his business.
