Activity Descriptions
PHASE ONE: Engagement
- What ARE these? #1
Teacher provides students with a collection of objects, such as
colorful Dollar Tree Store erasers. These erasers are everyday objects
that have familiar qualities but their form may be unfamiliar.
- What are these? What purpose do they serve? Describe them.
- What do you see? What does it mean or do? How do you know?
B. What ARE these?? #2
- In groups of 3-4, students examine the microphotographs and answer
the question: WHAT is this?? At first, students will most likely try to
identify what is pictured, but encourage students to move beyond naming
organisms to exploring the purpose of these pieces of paper placed
before them. Useful questions might include: What is this? Why do these
photos exist? What purpose do these photos serve? Do you like them?
- Where have you seen shapes, colors, or images like these before? Why
do you think someone created these images? Do these look as if humans
made them? Do they appear to be natural objects?
Estimated time: 10 minutes if oral, 30 minutes if written and groups
share recordings
PHASE TWO: Exploration
A. Continuum Activity – Part One
- Students use the microphotographic images of organisms found both in
the ocean and the seashore to create a series of continua. A continuum
is created by moving classroom tables together to form longer tables. At
either end of the table a single word is placed. Typically, these words
are opposites.
Beautiful to Ugly
Organic to Human-made
Natural to Artificial
Smallest to Largest
Strongest to Weakest
Softest to Hardest
Land-like to Sea-like (only if the students come up with this!)
Fresh-water to Marine (again, only if the students come up with
this!)
Fast to Slow
- The closer to one end an image is placed indicates the degree to
which that image shares the attributes of that word. The closer to the
center of the continuum, the more neutral that word is in relationship
to both words.
- Students must debate reasons for placing images in certain locations
on the continuum.
- How would a scientist arrange these objects on a table? How would an
artist arrange these objects on a table? (Move this section to where it
makes sense).
- Please note that at this time students are NOT told that these are
photographs of living organisms and are artwork, but students should be
encouraged to make predictions about the identity of the organisms
pictured as well as the purpose of the photographs.
Estimated time: 45 minutes
PHASE THREE: Explanation
A. Continuum Activity – Part Two
- Now that the students have had an opportunity to explore the
materials available, students are told that materials are
photomicrographs of microscopic organisms found in the ocean and on the
seashore. It is also explained that research
scientists in the Department of Ocean, Earth & Atmospheric Sciences at
Old Dominion University, Dr. Lisa Drake and Dr. Martina Doblin,
photographed these organisms, and colorized the images to produce
contrast. Contrast is a device used by photographers, artists, and
scientists in order to determine what is being viewed in an image.
Because the images have been colorized and no longer represent the
natural colors of the organisms and their environments, they are no
longer meant to be representations of organisms but are instead viewed
as photographs -- as works of art.
- Following this explanation, students are asked to re-examine their
continua and develop new continua utilizing this information. Also,
students would now build a continuum from land-like to ocean-like.
- As an extension of this assignment, biology students can write
position papers that defend their arrangement of photographs along their
designed continuum.
- Art students can write position papers that defend their arrangement
of the photographs along continua that rely on visual distinctions, such
as: Beautiful to Ugly; Art-like to Not Art-like
Estimated time: 30 minutes
B. Categorization Activity – Part One
- In groups of 2-4, students view the selection of microphotographic
images of marine organisms.
- Next, the students are asked to categorize and group the images. The
reasons for grouping images will be determined by the students. For
example, students could group images by color; by whether they think
certain images depict plants or animals; or by other factors.
- After each group has created and recorded their groupings, they will
share their decisions with the rest of the class.
- As an extension to this assignment, the teacher can provide each
group with additional images similar to the ones that have already been
placed into groups. Students must now determine into which
groups/categories these images should be placed and do so using
well-formulated explanations. The teacher should make sure that students
support their answers with responses that begin with phrases like
"…because…" and "…for example…"
Estimated time: 20 minutes
C. Categorization Activity – Part two
- Students now explore ways that scientists classify organisms
utilizing resources available. At this time, students have two questions
in mind: "HOW do scientists classify living organisms?" and "WHAT are
their decisions based on?"
- Using the new information they find, students categorize the
microphotographs provided. For example, now that the students know that
these indeed are photos of living organisms students could begin by
using the three basic categories - plant, animal, fungus - and then
build their arguments from their decisions.
- As an extension to this assignment, biology students can develop a
dichotomous key to classify a set of given images. Students then would
have the opportunity to test their dichotomous key with new images
provided. Dichotomous keys would be designed to identify organisms in
terms of Kingdom through species.
- A resource that would be useful to help students observe how
scientists classify organisms would be the Audubon Guide to Atlantic
Seashores. This text categorizes organisms commonly found on the beach
into different groups based on morphology, size, and color. This would
serve as a working guide of what students will be doing in this
activity.
- How would artists classify these same organisms? Would they classify
organisms at all? Would they use form, color, texture? Would the groups
be different?
- Once the categories are established, each student could create an
image of an imaginary plant, animal, or fungus organism that would meet
the requirements of one of the categories. Students could create
drawings, paintings, or computer generated images to satisfy the
requirements of this activity.
Estimated time: depending upon resources available, 30 minutes to 90
minutes (not including dichotomous key extension activity)
PHASE FOUR: ELABORATION
A. Viewing and Recording – Part 1
- In pairs, students use microscopes or hand lenses in the classroom to
view microscopic organisms in water/slurry collected from local ponds,
rivers, oceans, and other bodies of water. While viewing the organisms,
students record what they see through drawings in their sketchbooks. As
students draw, they should also record notes that indicate colors,
textures, or other visual qualities of the organisms. Students should also
be encouraged to record notes regarding behavior and location of the
organism.
- Record observations about the behavior that they are observing of the
organisms.
- Later, the drawings should be enhanced with colored pencils or with
watercolors.
Estimated time per observation period: 25 minutes, minimum.
B. Viewing and Recording – Part 2
- As an extension to the other viewing and recording task, students
could collect samples and make hypotheses about what will happen to
their samples over time based on their knowledge from previous tasks.
Students would view and record samples over a period of time and record
changes to the samples. As a further extension, students could take
samples at pre-selected locations within their water/slurry sample and
make hypothesis and gather data about changes that would occur at each
of their pre-selected locations within their water/slurry sample. For
example, samples could be taken from the middle of the sample at a depth
of 3 cm, towards the left edge of the sample container at a depth of 3
cm, in the middle of the sample at a depth of 10 cm, in the middle of
the sample at the surface of the sludge found at the bottom of the
sample, and in the middle of the sample at a depth of 1 cm into the
sludge found at the bottom of the sample.
- A good resource for identifying organisms found in water/slurry
samples is
Rainis, K.G. and Russell, B.J. (1996). Guide to microlife.
Danbury, CT: Franklin Watts of Grolier Publishing.
- This task could be extended to incorporate concepts such as
variation, adaptation, natural selection, species succession, niche,
photosynthesis, cellular respiration, consumer, producer, and food web
to name a few.
- How would artist approach this? Clay slaking down over time and
being reclaimed. Creating porcelain and clay bodies that develop
bacteria. Clay body changing properties over time and with
interactions with the environment.
(Monet. Changing light over time: haystack paintings, cathedral
paintings, and the garden. The construction of the garden as an
unnatural creation of natural elements. Linnea in Monet’s Garden.)
- Growing bacteria on petri plates.
Estimated time per observation period: 25 minutes
Estimated number of observation periods: at least twice per week,
preferably for a period of 3 months with more advanced students for
collecting evidence of species succession
C. Viewing and Recording – Part 3
- In the preceding "viewing and recording" tasks, students could act
as both scientists and artists. As scientists, students would make
hypotheses, collect data, and report the findings.
- As artists, students would learn about the work of Buster Simpson
and his approach to creating art that depends on the reactions of
bacteria, oxidation, and microscopic organisms found in waterways near
factories and industrial plants, on the surfaces of ceramic plates.
- Students would also be introduced to the work of local ecological
artist, Rosa Doughty, via the website
http://www.rainfulart.20m.com.
This site explains her past and on-going projects in the Norfolk area.
Her most recent project in the Norfolk area is detailed on her website.
This site describes a performance art piece where water and slurry
samples were taken from Elizabeth River, Lafayette River, Northern
Branch, Crab Creek, and Wayne Creek. At each of these sites the water
and slurry samples were allowed to ceremoniously evaporate, and tiles
made of earth, water, and/or trees were left at each site. Individuals
were encouraged to participate in the performance by emailing her about
the tiles and to utilize the opportunity to complete the performance by
responding to the condition of the world. Rosa Doughty has offered to
visit classrooms and serve as an email pen pal with any
classrooms/students/teachers interested in her work. Her email address
is rainfulart@netscape.net
- Electronic communication, chat rooms, dialogues with other artists,
scientists, and students within the project and around the world.
Include Martina Doblin and Lisa Drake among the experts with whom
students can communicate.
Estimated time: 45 minutes
D. Debate
- Students will debate whether a scientist who takes microphotographic
images of marine organisms, colorizes them, prints them, and then
displays them on the wall is an artist, a scientist, a combination of
the two, or neither. Divided into four small groups, each group is given
one of the platforms on which to make an argument. The students have 20
minutes to formulate their arguments, record their reasons, and rehearse
their arguments.
- A formal debate is arranged among the four groups, each taking a
different corner of the room but facing the center of the room and each
other. One at a time, a spokesperson from each group provides one
statement lasting no longer than one minute in which he/she attempts to
argue the perspective of the group.
- Upon completion of the debate (once all students have had an
opportunity to argue at least one point), the entire class will discuss
the arguments and attempt to reach a consensus or understanding of the
complexities of the arguments and the situation.
- At the conclusion of the debate, each student should formulate his
or her own position statement. Student position statements should be no
longer than a paragraph (3 to 6 sentences) and should make clear which
of the four possible responses to the question "Is a scientist who takes
microphotographic images of marine organisms, colorizes them, prints
them and then displays them on the wall an artist, a scientist, a
combination of the two, or neither?
Estimated time: 45 minutes
PHASE FIVE: Evaluation
A. Visual Display of Data
- Students would create graphic diagrams to present the findings of
their observations. Examples of such graphic diagrams would include bar
graphs to show the populations of different species within their
samples, concept maps to illustrate their understanding of the
interactions existing within their samples, concept maps to illustrate
their understanding of the scientific processes occurring within their
samples, and histograms to illustrate class opinions before and after
the debate outline in the previous activity. As an extension of this
activity, students could discuss the appropriateness of one type of
graphic representation over another and compare their conclusions to
those of the "experts."
- Students would create works of art that take advantage of the
chemical reactions or other changes that occur to materials that they
learned during their scientific observations.
- Students would create digital images of samples collected from
previous activities, download them on a computer, colorize or otherwise
alter the visual representation of the images, and then print the images
for exhibition purposes or publish them on the class website.
- Visual display of data and art for evaluative purposes would need to
address all three essential questions
- Based on the previous activities, students would be responsible for
responding to the following evaluative tasks.
- Create a position paper that compares what the term "investigation"
means to a scientist as compared to what it means for an artist.
- After being provided with a new source of pond water,
microphotographic images, or slurry, students design and conduct an
investigation using one of the approaches from a previous activity listed
above.
- Based on the findings of this investigation, students select one
approach to best present their findings.
Estimated time: 3 days
