|Lesson Plan ID:
Is the Cell Membrane Semi-Permeable?
As part of the study of the cell, students will perform a three day hands-on inquiry to determine if the cell membrane of an egg is semi-permeable. Students will work individually or in groups as they explore the functions of the cell membrane. Students will create a lab report using the scientific method. The program Excel or any other comparable program will be used to assist students with developing graphs and charts in for the data section. The Internet will be used to assist student in exploring illnesses associated the malfunctioning of the cell membrane.
This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMS-U Project.
|SC(7) ||1. Describe characteristics common to living things, including growth and development, reproduction, cellular organization, use of energy, exchange of gases, and response to the environment. |
|SC(7) ||2. Identify functions of organelles found in eukaryotic cells, including the nucleus, cell membrane, cell wall, mitochondria, chloroplasts, and vacuoles. |
|TC2(6-8) ||2. Publish digital products that communicate curriculum concepts. |
|TC2(6-8) ||5. Use basic features of word processing, spreadsheets, databases, and presentation software. |
|TC2(6-8) ||14. Use digital tools to generate new ideas, products, or processes. |
|SC2015(7) Life Science||3. Construct an explanation of the function (e.g., mitochondria releasing
energy during cellular respiration) of specific cell structures (i.e., nucleus,
cell membrane, cell wall, ribosomes, mitochondria, chloroplasts, and vacuoles)
for maintaining a stable environment. |

2. Communication and Collaboration
Students use digital media and environments to communicate and work collaboratively, to support individual learning and contribute to the learning of others. Student:
a. interact, collaborate, and publish with peers, expert, or others employing a variety of digital environments and media.
b. communicate information and ideas effectively to multiple audiences using a variety of media and formats.
3. Research and Information Fluency
a. plan strategies to guide inquiry
b. locate, organize, analyze, evaluate, synthesize, and ethically use information from a variety of sources and media
c. evaluate and elect information sources and digital tools based on the appropriateness to specific tasks.
d. process data and report results.
|Primary Learning Objective(s):
Students will understand the process of how water travels from the outside of the egg through the cell membrane into the egg when submerged in distilled water .
Students will understand the process of how water travels from the inside of the egg through the cell membrane when submerged in corn syrup.
|Additional Learning Objective(s):
In doing research about the problems associated with the cell membrane, students will expand in their knowledge of using the Internet for research. In creating the video and lab report, students will acquire skills that broaden their level of using technology.
|Approximate Duration of the Lesson:
|| Greater than 120 Minutes|
|Materials and Equipment:
Each student will need:
2. 100 mL beaker
3. Triple Beam Balance
4. 50 mL distilled water
5. 50 mL corn syrup
|Technology Resources Needed:
Digital Camera for pictures for website, computer lab for student research, and web sites.
|Attachments:**Some files will display in a new window. Others will prompt you to download.
See attachments or use the data collection sheet and rubric to evaluate the lab report. The video recording of disease can be evaluated for effort/participation.
Students should all complete assignment in the same time duration. If time permits for more advanced students, they should create a podcast for the website detailing the functions of the cell membrane and some of the diseases of associated with the cell membrane.
For information on how to produce podcasts, visit:
Grouping students should assist students with measuring, collecting data, and creating a lab report. A mentor student can assist remedial students in the completion of the assignment. All students should be encouraged to participate in the lab.
Each area below is a direct link to general teaching strategies/classroom
for students with identified learning and/or behavior problems such as: reading
or math performance below grade level; test or classroom assignments/quizzes at
a failing level; failure to complete assignments independently; difficulty with
short-term memory, abstract concepts, staying on task, or following directions;
poor peer interaction or temper tantrums, and other learning or behavior problems.
