EXPERIMENT 2: SWEAT GLAND DISTRIBUTION Sweat glands, also called sudoriferous glands, are found all over the body and produce a substance composed of salt and water. These glands regulate body temperature. In this experiment, you will measure the density of sweat glands in different areas of the body. PROCEDURE 1. Carefully measure and cut out four 5 cm by 5 cm squares of graph paper. 2. Locate regions on your right anterior forearm, right palm, right anterior thigh, and right anterior foot that do not have large creases. For example, the elbow region would NOT be an ideal region for this experiment. 3. Use the Betadine® swab to paint a square on each of the selected regions. This square should be slightly larger than the graph paper squares you cut in Step 1. 4. Allow the Betadine® to dry for 1 minute. 5. Use the tape to secure a square of graph paper on each painted square. Be sure the graph paper is securely fastened. Keep the graph paper in place for approximately 20 minutes. 6. After 20 minutes, remove each graph paper square one at a time. 7. Count the number of dots on each square. Each dot will appear as dark blue, brown, or black, and represents a sweat gland. Record the number of sweat glands per square centimeter in Table 2. Note: Your Betadine® swab may not produce a high number of dots if your body does not sweat very much. This is normal. 8. To remove the Betadine® from your skin, wash each area thoroughly with soap and water. ©eScience Labs, 2016 Data SheetExperiment 2 Data Sheet Table 2: Sweat Gland Distribution Body Region Sweat Glands/cm2 Right Anterior Forearm Right Palm Right Anterior Thigh Right Anterior Foot ©eScience Labs, 2016 1 Running Title: LAB REPORT TITLE 2 LAB REPORT TITLE Lab Report Title Student’s Name Ivy Tech Community College APHY 101-XX Month/Day/Year Abstract Start with a single paragraph that summarizes the entire experiment.

EXPERIMENT 2: SWEAT GLAND DISTRIBUTION
Sweat glands, also called sudoriferous glands, are found all over
the body and produce a substance composed of salt and water.
These glands regulate body temperature. In this experiment, you
will measure the density of sweat glands in different areas of
the
body.
PROCEDURE
1. Carefully measure and cut out four 5 cm by 5 cm squares of
graph paper.
2. Locate regions on your right anterior forearm, right palm,
right anterior thigh, and right anterior foot that do not have

2. large
creases. For example, the elbow region would NOT be an ideal
region for this experiment.
3. Use the Betadine® swab to paint a square on each of the
selected regions. This square should be slightly larger than the
graph paper squares you cut in Step 1.
4. Allow the Betadine® to dry for 1 minute.
5. Use the tape to secure a square of graph paper on each
painted square. Be sure the graph paper is securely fastened.
Keep the graph paper in place for approximately 20 minutes.
6. After 20 minutes, remove each graph paper square one at a
time.
7. Count the number of dots on each square. Each dot will
appear as dark blue, brown, or black, and represents a sweat
gland. Record the number of sweat glands per square centimeter
in Table 2.
Note: Your Betadine® swab may not produce a high number of
dots if your body does not sweat very much.
This is normal.
8. To remove the Betadine® from your skin, wash each area
thoroughly with soap and water.

Abstract
Start with a single paragraph that summarizes the entire
experiment. It is usually easiest to write the abstract last (even
though it will appear first in the report). Briefly state the
purpose of the experiment. Then identify the hypothesis being
investigated. Next give a brief description of the general
methods used to conduct the experiment. After describing the
methods followed, write one or two sentences providing the key
results found; note trends or patterns found in data. Next
indicate if the results of the experiment support your
hypothesis. Explain why or why not.
Keywords: Include a list of important terms in the report.
Lab Report Title
Type your introduction here. This is a paragraph that states
the main topic and key ideas of the experiment. State your
purpose and hypothesis. It may feel somewhat repetitive with
the abstract, but go into more detail about the overall purpose of

5. the experiment and how it is relevant to what you are learning
in class.
Methods
Use a sufficient level of detail to describe the process used
to conduct the experiment. The description provided should be
sufficiently detailed so the reader can clearly understand the
steps you took to complete the experiment. List the equipment
or supplies used and any specific timing involved in the
experiment (as applicable). This section may be multiple
paragraphs long depending on the number of steps involved in
the experiment.
Results
In this section, describe the results of the experiment. Include
any data collected. The data may be presented using paragraph
descriptions, tables, graphs, or a combination of these. When
using tables and graphs, be sure to include titles, proper units,
etc.
Graph 1: Chart Title Describing Results
Discussion
In this section, interpret the results of the experiment. Draw
conclusions and support those conclusions with your data. State
whether or not your hypothesis was correct. Explain why or why
not. If there were any specific questions your instructor asked
you to address in the discussion, this is the place to include it.
Make connections between observations made in the lab
experiment and concepts you are learning about in the course.
Note if there were any limitations or errors encountered while
conducting the experiment. How could it be improved? What are
some next steps you can think of for future studies/experiments?
This section may be several paragraphs long.
Use internal citations throughout the document whenever you
are referencing ideas from another source. The internal citations
should appear in parentheses at the end of the sentence or
section containing the referenced material. The citation should

6. include the author(s)’ names and the year of publication.
Example: (McDonough, 2017)
