| Overview:
In order to conduct research on a study site outside your school, or in
a local park or preserve what are the different tasks you and the students
need to plan? (i.e. field research/activities, compiling data, planning
field trips, developing a presentation for your classmates, principal,
parents, or beginning work on developing a website). What different types
of research teams do we need? (i.e. plant, animal, bird experts) What other
special talents can students contribute to their team's project? (drawing,
writing, technology expert, data collection etc.)
One challenge
is to find and name as many animal and plant species that are found in
the natural habitat near your school. The class should do a KWL (Know,
Want to Know, Learned) chart or brainstorm what they know about the study
area and its inhabitants. How can you tell which animals use or live in
this habitat? How can we document the information you collect?
Next, list
the things you will need to take on our first 'walk through of the study
site. See 5-Minute Point Count and Sketch of the Study Site activities
that follow. How can you record our general observations of the study site?
On another
trip through the study site, we will want to collect more detailed data
on the animals and plant species found there. What is a good way to look
for animal clues and record this data? How can we collect plant samples
and organize them? Who could we contact to find out about how scientists
do these tasks?
Where might
we find resources for identifying the plants and animals? Can you bring
in some resources or URLs (websites) that will have information that we
might use?
What will our
action plan look like? What do we need to accomplish? Once you've decided
what needs to be done, here are some possible research groups that may
be useful.

Using Field Techniques
5 Minute Point
Count
Purpose:
Provide an organized format for gathering general animal data.
Teacher
Information: This activity should be done as you QUIETLY enter a study
site. Students are asked to spread out and sit quietly for five minutes
and make observations of all the things they see and hear around them.
Brief notes of insects, spiders, scat, evidence of mammals, and birds seen
or heard nearby. This activity helps students to focus on all the critters
in the habitat study site. This activity can be repeated at intervals throughout
the study area. Watch for animal signs as you walk along. Be sure to have
students record the time, weather conditions and date in their journals
or 5-minute point count data sheets.
Materials:
clipboard
with bull clip or butterfly clip
data collection
sheet (see 5-minute point count data sheet)
pencil on
a string attached to the clipboard

in your journal.
Sketch of the
Study Site
Purpose: Provide
an organized format for getting the 'big picture' of the study site.
Teacher
Information: Prior to going out in the field, the teacher should briefly
explain what a scientist's sketch might look like; a sketch, not an artist
drawing. Have students do a centerfold on the paper. When you arrive at
the study site, set the parameters for the drawing: what should be on the
left side, where center is for the sketch, and what should be on the right
side of the sketch. Label any known vegetation or objects. Depending on
the size of the site, several drawings can be done or one panoramic sketch.
Be sure to have students label each sketch as to the location, the time,
weather conditions and date on the sketch. Be sure to ask students why
scientists find it important to sketch sites when collecting data in the
field.
Materials:
clipboard
with bull clip or butterfly clip
drawing paper
pencil on
a string attached to the clipboard
jeweler's
loupe or hand lens on a string
Procedure:
Determine the location of your study area. Before taking the students into
the field prepare their clipboards and other equipment needed for them
to complete their study. Explain to the students what a scientist's sketch
looks like. Have them make a small center fold on the paper. When the students
arrive at the study site, have them sit quietly and listen as you explain
the parameters for the drawing - what should be on the left side, where
center is for the sketch, and what should be on the right side of the sketch.
Students should label any known vegetation or objects. Depending on the
size of the site, students can make several drawings or one panoramic sketch.
Be sure to have students label each sketch with the location, time, and
weather conditions. Why do you think sketches are important to scientists
when they are collecting data in the field?

Making an Herbarium
An herbarium is
an organized collection of vegetation samples.
Materials:
5 X 8 plain
index cards
clear scotch
tape
plant presses
or newspapers & student texts or encyclopedias
clear contact
paper -cut in 6 X 9 pieces
information
labels (sample below)
zip lock bags
work gloves
pruning shears
permanent
markers
Teacher
Information: Conduct a field trip of the study site and have students
or teams gather samples of the various plant species. You may wish to set
minimum or maximum number of specimens to collect. A "good sample" includes
a specimen with leaves, stem, roots (flowers, if possible).
NOTE: If
a plant is found that is unusual and there are only a few in the area,
ask students why they should or should not collect the roots of this plant?
The plant could be a rare, threatened or endangered. Students should
collect the specimen and place it in their ziplock bag. While in the field
they should note in their journal where they collected their specimen,
the time, description of site and the name of the plant. This record should
be numbered or lettered and the same number should be written on the bag
with the permanent marker.
You may also
want to consider taking photos of the plants as specimens are collected.
Digital cameras are wonderful in the field and the photo can help in identifying
the plant. You may want to assign one-two students to be the project photographers.
They will also need to keep information in their journals concerning the
location of the plant, the number assigned by the "researcher", and the
number of the photograph.
If a walking
tour is done with a plant expert, samples may be immediately taped to an
index card and labeled. The same drying procedure is used for the taped/labeled
index card specimens.
Drying Procedure:
Gather all the samples and then place specimens in sheets of newspaper
to dry. Student textbooks /encyclopedias can then be stacked on top of
the plant samples as they dry. Make sure students place a temporary label
with the plant so they can refer back to their journal entry for the final
label. After several days or a weekend, the plant samples can be mounted
and taped onto the 5 X 8 index cards. The generic label information is
added for each sample.
Labeling
process: Each specimen needs to be labeled with the date, location,
county etc. Clear contact paper can be used to preserve the specimens.
The final products
might be:
-
A herbarium on
a ring - samples are carefully mounted and labels filled out. Cards may
be covered with clear contact paper to help preserve the specimens.
-
index cards stored
in a perforated veggie bag - all the samples are carefully mounted and
labeled then stored in a perforated vegetable bag.
-
a sample herbarium
in a manila folder - plant specimens are mounted and labeled and then organized
by type of sample. i.e. grasses, shrubs in manila folders.
Herbarium samples
should be gathered several times throughout the year as the vegetation
changes in the study site.
Other suggestions
for creating a classroom herbarium:
-
When collecting
samples from trees, it's helpful to have a sketch of the shape of the tree.
-
Students should
separate their specimens by species - i.e. grasses, shrubs, forbs, trees
etc.
-
Identifying native
plants and alien species.
-
Provide students
with samples of properly labeled specimens so they have a good model of
what an acceptable herbarium looks like.

Expert Data Collection Procedures
Materials needed:
-
30m or 50m tape,
-
1m tape for every
2 students,
-
2 stakes to hold
the 50m tape
-
4 stakes to mark
the corners of the 10m square
-
12-15 Hula Hoops
(borrowed from the PE teacher)
-
Sample Plot Frames
(directions for building included)
Four procedures
for collecting plant and animal data are explained below. Each procedure,
except the random hoop toss, allow for the study to be replicated from
season to season or year-to-year. The 10 meter square plot and the random
hoop toss both provide for gathering data for a large area. The Hoop transect
and Sample Plot Frames provide a way to focus in on more precise data collection.
After reviewing the four procedures, you and your classmates will need
to decide which methods will best meet your research needs.
Random Hoop Toss
Procedure:
The random hoop toss provides a simple format for focusing on plant life
and or animal life within a limited plot area. Students should gently toss
the hoop backwards over their head. Have the students walk to the spot
where the hoop landed. It is their responsibility to sketch all the things
observed within the hoop. This procedure is repeated by each team 3-6 times
within the assigned plot area. The data for each hoop toss is then summarized
to determine the dominant species of plants and animals for the study site.
Student
Focus Questions:
Why is it
important to do random sampling?
Should you
count specimens only partially inside the hoop?
You and your
classmates will need to agree on some 'ground' rules. Why is this important?
10 Meter Square
Procedure:
The 10m square is another technique used to collect the number of species
in an assigned area. Teams will need 4 stakes, several tapes or some string
to mark off the 10m square. Note: This technique may be more appropriate
for an area with less ground vegetation and larger vegetation. Different
species can then be counted. The results from each 10m square should be
compiled and summarized.
Student
Focus Questions:
Ask your students
if they can you think of a way to keep track of the number of different
species of plants they've observed within the square? Are they able to
see signs of insects and other animals? Be sure to document those findings.
How can you document a 'good find' that isn't inside the 10m square?
Hoop Transect
Procedure:
The hoop transect procedure uses hula-hoops, 1-meter tapes and a 50m tape
and 2 stakes. Assign your 2 student teams a particular plot to sketch and
document. This technique will help them to focus in on the plants, insects
and animal signs within a given plot.
Student
Focus Questions:
How far apart
will you need to be to effectively sample an area?
How can you
document your location so that you and your classmates can return at another
time to replicate this study?
Why would
it be important to be able to visit the same exact plot at another time?

Sampling Plot
Frame
A sampling plot
frame provides another more detailed way for students to focus on the dominant
plant species. Insect and animal evidence can also be documented. Each
team of 2 - 3 will need a plot frame to use and a meter tape. Plots will
be assigned in a manner similar to that of the hoop transect. Be sure to
have student label their exact location from the 50m tape. The class will
need to decide how to record their observations of ground cover for each
decimeter square (10cm X 10cm). Will they choose to use 10%, 20%... or
>50% or <50%?
Student
Focus Questions:
Will you do
a sketch, name the dominant species or collect a sample for each section
of the frame?
How do you
document a 10cm square with no vegetation?
How can your
class summarize this data?
When do you
think scientists would use this precise data?
