Cell Membrane

Lesson Plan

State Standards:

High School Biology
2.1 Relate cell parts/organelles (plasma membrane, nuclear envelope, nucleus, nucleolus, cytoplasm, mitochondrion, endoplasmic reticulum, Golgi apparatus, lysosome, ribosome, vacuole, cell wall, chloroplast, cytoskeleton, centriole, cilium, flagellum, pseudopod) to their functions. Explain the role of cell membranes as a highly selective barrier (diffusion, osmosis, facilitated diffusion, active transport).
SIS1. Make observations, raise questions, and formulate hypotheses.

SIS2. Design and conduct scientific investigations.
o making observations
o making and recording measurements at appropriate levels of precision
o collecting data or evidence in an organized way
SIS4. Communicate and apply the results of scientific investigations.

Essential Question:

Why is the difference between structure and function?

Lesson Question:

What are the structure and function of the cell membrane?

Introduction:

You are a designer for computer and internet teaching tools. The students that always send you cookies on your birthday, and flowers in the spring, are struggling with the difference between cell membrane function and cell membrane structure. They need your help. The topic will require a little bit of research.

Task:

Create a computer driven presentation that teaches the essentials of cell membrane structure and function. Presentation must clearly show the difference between the structure and the function of the cell membrane.


STEP 1 -VIDEO


Watch the video above and answer the following questions on a piece of paper:
1) Why is the lettuce changing shape?
2) Where in the lettuce is the change happening?
3) What factor(s) contributes to the shape change?

STEP 2 - QUIZ

1) Click on the quiz link.
2) Look for “Pre-Test: Cell Membrane Structure and Function” and click on “Take Test”.

STEP 3 – INVESTIGATION

1) Download and print “Diffusion Investigation” and follow instructions.
2) Download and print “Diffusion Lab Sheet” and follow instructions.

STEP 4 – PRESENTATION AND NOTES

Please view and take notes on the following Prezi presentations:

1)

Cell Membrane Structure on Prezi


2)

Cell Membrane Function on Prezi


STEP 5 – QUIZ

1) Click on the quiz link.
2) Look for “Cell Membrane Structure and Function” (not pre-test) and click on “Take Test”.

STEP 6 – PRESENTATION (Individual)

Create a computer driven learning tool that fulfills the following requirements
1) Must be a computerized presentation using Powerpoint, Prezi, Glogster YouTube, or any other program approved by the teacher. (Glogster example:)
2) Presentation must be 4-6 minutes long.
3) An explanation of cell structure must be included.
4) An explanation of cell function must be included.
5) A helpful “hint” for remembering something about cell structure and function must be included.

STEP 7

Read about dialysis, after reading the article:

(1) Write down three important facts from the article that relate to cell membrane structure and/or function.
(2) Write down three questions you have about dialysis.

Lesson Experiences:

1. You will watch a video and answer some questions.
2. You will take a pre-assessment quiz.
3. You will perform a lab investigation.
4. You will review and take notes on a presentation.
5. You will re-take the pre-assessment quiz.
6. You will create a computer driven presentation
7. You will read an brief article and answer some questions.

Conclusion:

Finally, now that you know all there is to know about carbon compounds, take this Carbon Compound online quiz.

Procedure and materials Procedures and materials are listed in clear steps. Each step is numbered and is a complete sentence. Procedures and materials are listed in a logical order, but steps are not numbered and/or are not in complete sentences. Procedures and materials are listed but are not in a logical order or are difficult to follow. Procedures and materials do not accurately list the steps of the experiment.
Data Professional looking and accurate representation of the data in tables and/or graphs. Graphs and tables are labeled and titled. Accurate representation of the data in tables and/or graphs. Graphs and tables are labeled and titled. Accurate representation of the data in written form, but no graphs or tables are presented. Data are not shown OR are inaccurate.
Error Analysis Experimental errors, their possible effects, and ways to reduce errors are discussed. Experimental errors and their possible effects are discussed. Experimental errors are mentioned. There is no discussion of errors.
Analysis The relationship between the variables is discussed and trends/patterns logically analyzed. Predictions are made about what might happen if part of the lab were changed or how the experimental design could be changed. The relationship between the variables is discussed and trends/patterns logically analyzed. The relationship between the variables is discussed but no patterns, trends or predictions are made based on the data. The relationship between the variables is not discussed.
Conclusion Conclusion includes whether the findings supported the hypothesis, possible sources of error, what could be done to improve investigation, and what was learned from the experiment. Conclusion includes whether the findings supported the hypothesis, source of errors, and what was learned from the experiment. Conclusion includes whether the findings supported the hypothesis and what was learned from the experiment. No conclusion was included in the report OR shows little effort and reflection.
Participation Used time well in lab and focused attention on the experiment. Used time pretty well. Stayed focused on the experiment most of the time. Did the lab but did not appear very interested. Focus was lost on several occasions. Participation was minimal OR student was hostile about participating.
