Assignment: Cellular Processes
Substances generally move across a cell membrane from an area of higher
concentration to an area of low concentration. Factors such as changes in
temperature, pressure, and concentration can affect the rate at which this
movement occurs. In this assignment, you will plan an investigation
into one factor and how it affects the rate of diffusion or osmosis.
Instructions
Your task is to plan and conduct a simple experiment to test how one factor
affects the rate of diffusion or osmosis using household items found around you.
As an inquiry-based activity, you need to design your own experiment, including
the following:
Determine an appropriate ‘Testable Question’.
? Propose a reasonable hypothesis based on your ‘Testable Question’.
? Develop a procedure based on your ‘Testable Question’.
?
Step 1: Planning Your Experiment
1. Determine the testable question you wish to investigate. Ensure that your
testable question can be answered using quantifiable data and not simply
qualitative observations.
2. Once you have decided on your testable question, propose a reasonable
hypothesis for the experiment you plan to conduct. Your hypothesis should
explain how the change in your independent variable will affect your
dependent variable. As previously stated, the change in your dependent
variable should be quantifiable.

3. Develop the procedure for the experiment you intend to conduct to test your
hypothesis. Your procedure should be specific and detailed, allowing another
scientist to recreate your experiment using the exact steps you used in your
investigation. Write the steps of the procedure in the past tense.
4. Upload your testable question, hypothesis, and planned procedure to the
Assignment: Cellular Processes—Procedure Dropbox. Your teacher will review
your work to ensure your experimental plan is correct.
Important
A part of your grade for this assignment is directly linked to the completion of
Step 1 of this activity. Your teacher will not only evaluate your initial effort but
also your ability to implement the instructor’s feedback into your experiment.
It is strongly recommended that you submit Step 1 of this activity before
conducting your experiment and finalizing your report.
Note
Refer to the “Planning an Investigation” page in the Scientific Skills and
Formatting module to help you plan your test.
Step 2: Conducting Your Experiment
1. Apply any feedback from your teacher to your planned experiment.
2. Conduct your experiment to test your hypothesis.
Step 3: Communicating Your Results
1. Once you have completed your test(s), communicate your results in a lab
report.
2. Your lab report should include the following sections: testable question,
hypothesis, materials, procedure (including your identified variables),
observations, results, discussion, and conclusion.

module to help you write your report.
Safety
Performing hands-on lab activities is another way to learn and discover how
science concepts apply to our everyday lives. However, it can also be
dangerous if you do not take steps to perform these activities safely. We have
made every effort to ensure that these activities are safe to perform in the
presence of an adult (ex. teacher or parent). Use good judgment, and exercise
every precaution in order to avoid accidents that may result in injury.
If you have any questions about the materials or procedure of a lab activity,
email your teacher prior to beginning any lab activity.
Assessment Details
Your submission should include the following:
?
Step 1: Your testable question
?
Step 1: Your hypothesis
?
Step 1: Your planned procedure
?
Step 2: Your report
?
All in-text citations and reference list for sources used in your final report
Upload your testable question, hypothesis, and procedure to the Assignment:
Cellular Processes—Procedure Dropbox.
Upload your lab report to the Assignment: Cellular Processes—Report Dropbox.
? Please note that this assessment contains two unique Dropbox folders.
Submit components of Step 1 to the Procedure Dropbox, whereas
components of Step 2 should be submitted to the Report Dropbox.

Assignment: Cellular Processes
All information and relevant data are to be included in a logically sequenced
manner. In your writing, use appropriate writing style, tone, and scientific
terminology. Conduct your research using reliable, peer-reviewed and industry
sources, and ensure that sources listed in your reference list directly relate to
information presented in your paper. Use the appropriate referencing style for
science to cite your sources. For more information, see the page titled
“References” in the Scientific Skills and Formatting module of the Introduction
unit in your course.
Submit this assignment to the dropbox. This assignment will be evaluated for a grade that will
contribute to your overall final grade in this course.
