Egg Lab Directions

Fun with an Egg and Osmosis

Osmosis is a very important process for moving WATER through membranes in and out of cells. We are going to take an egg and immerse it in Acetic acid for a day. The acid will remove the shell, providing a natural cell membrane around a giant cell with which to experiment. We will observe when water moves inside and outside of the egg, which is determined by the concentrations of water in and out of the cell. Read the ENTIRE LAB, and then write 2 hypotheses.

Write EVERYTHING in your lab book. This should include: Prelab, Lab Materials, Methods (procedure), Data (Data Table & Observations), Interpretation, and Conclusion.


Hypothesis 1: After removal of the shell, what will be the direction of osmosis, into or out of an egg when placed in vinegar? The egg is 8% dissolved substances and 92% water. Vinegar is 5% solute and 95% water. Explain your reasoning.

Hypothesis 2: What will be the direction of osmosis, into or out of an egg when placed in corn syrup? The syrup is 60% solute and 40% water. Explain your reasoning.

LAB: Experimental Design


Graduated cylinder
Overflow can
Clear plastic cup
Corn syrup
Saran wrap


DAY 1:
1. Measure the mass, volume, and circumference of an egg. How you do it is up to you. Record observations in data table.
2. Set the egg in a plastic cup and pour vinegar over the egg until it is covered with about 3 cm of liquid. Cover the cup with saran wrap.
3. Observe any chemical reactions taking place and record these in the data table. Place the beaker and egg in your drawer for 24 hours.

DAY 2:
1. Observe any changes to the egg and record.
2. Carefully remove the egg, rinse and dry it. Measure the mass, volume, and the circumference again. Record data and observations.
3. Pour on the vinegar and rinse the cup. Add 1 inch of corn syrup to your cup then add the egg. Cover and leave in your drawer for 24 hours.
4. Answer questions 1-3 in the interpretations.

DAY 3:
1. Carefully remove the egg and measure the mass, volume, and circumference again. Record data.
2. Observe any changes to the egg and record the data and observations in the table. Be sure to fill in each box in the table. Label the units in parentheses.


Data Table

Data Continued: Describe qualitative changes in the egg.


1. After the shell was removed when immersed in vinegar, in which direction did the water move, into or out of the cell?
2. Use tonicity terms to compare the egg and the vinegar when initially placed together.
3. Explain the direction of the water’s movement in terms of the concentration of water, both in the egg and in the vinegar.
4. After immersion in the syrup in which direction did the water move, into or out of the cell?
5. Use tonicity terms to compare the egg and the syrup when initially placed together.
6. Explain the direction of the water’s movement in terms of the concentration of water both in the egg and in the syrup.
7. For centuries, salt and strong sugar solutions like corn syrup have been used to preserve foods and protect them from being colonized by living bacteria and fungi. This was long before refrigeration was invented. Why do these solutions defend against spoilage so effectively? The egg was a model of all cells including bacterial and fungal cells, which spoil food. What would happen to bacteria and fungi which land on food treated by these substances?


Restate your hypotheses and tell if they were supported, contradicted, or not supported.

Monday: Quiz & Notes

Today was the Cell Variety Quiz
Today we attempted to take 3.3 Notes on the Cell Membrane

We'll finish the notes tomorrow - yes with a powerpoint, yes, there are IMAGES you need to understand. It doesn't make sense to learn this just using words. You can handle drawing these into your notes.

Homework for Tuesday:

Read 3.3
Read 3.4
Read the Egg Lab
One uncooked, unfertilized egg (one per lab pair)

Homework for Wednesday:

Rotifer lab (links below)

Friday: Rotifer Lab, Upcoming Dates

Today ends the current microscope-stravaganza with the Rotifer lab - a look into one teacher's bird bath water to see the wonders of microscopic animals. There is a short set of questions to answer along with this.

I have decided to push back the due date on the Cell Organelle Project to Monday, November 3rd. Before you throw a parade, understand the the upcoming due dates will look like this:

Monday, Oct. 27: Cell Diversity Lab Due (in lab book), Lab Quiz

Tuesday: Start Egg Lab

Wednesday, Oct 29: Rotifer Lab Questions Due

Thursday: Finish Egg Lab

Friday, Oct. 31: TYPED WASL write up of Egg Lab Due. This can be mostly complete before you take your final measurements on Thursday, and you will have had Thursday to work on the class computers.

Monday, Nov. 3: Cell Organelle Project Due

Tuesday Nov 4: Tentative Ch. 3 Test Date

Cell Diversity Lab - Cell Organelle Project

Cell Diversity Lab: Tuesday, Wednesday, and Finished today!  Remember that the lab questions are due Monday.  This means you start Monday with the CELL DIVERSITY LAB QUIZ.  Don't forget!  It is open notes - but only with your composition book.

Today we also took Organelle Notes.  I know this is a lot of information.  It is all out of the book: section 3.2.  There are many tools in the book and online (!) which can help you sort out parts of the cell.

If you want to look at the PowerPoint again, a copy of it is in the Black Binder on the bookshelf in the back of the classroom.


Cell Organelle Project

Due: Wednesday October 29, 2008 by 2:30pm.

This project will be completed outside of class.

You will produce a travel brochure that describes a plant or animal cell as if it were a real destination. This could be an amusement park, ball park, zoo, farm, mall, etc., there are many possibilities!

You must accurately describe and diagram at least 10 organelles (attractions) from the list below. In your brochure, you must justify how you have represented their functions. The associated drawings or graphics must include the object the organelle represents as well as the drawing or graphic of the actual organelle. If you draw, you must draw neatly and your organelles must be neatly colored.
  • Decide on a plant or animal cell – each has its own specialized parts.
  • A good way to start would be to define and describe the function of each organelle/structure.
  • Figure out how the parts work together.
  • Decide on a business/vacation destination/factory/etc.
  • Align organelles and structures with the parts of your destination.

I will not accept projects that are not submitted in a brochure-like format.
I will not accept projects that do not fit into an 8 ½ inch by 11 inch area.

Plant Cells:
  • Central Vacuole
  • Cell Wall
  • Chloroplast
Animal Cells:
  • Centriole
  • Lysosome
All Cells:
  • Cell Membrane
  • Centrosome
  • Cytoskeleton
  • Endoplasmic Reticulum
  • Golgi Aparatus
  • Mitochondrion
  • Nucleus
  • Nucleolus
  • Plasma Membrane
  • Ribosome
  • Vacuole
  • Vesicle
These Organelles and Structures are described in the textbook Ch. 3.2.

Humor and creativity are strongly encouraged.

Note: At moments your teacher can be "thought impaired". Make sure you have a good justification as to why you have represented your organelles in the manner you have in your brochure.

  • Organelles described in the brochure with accuracy, having both a real organelle picture and a real world representation picture. 
  • Brochure Design Neat, no scribbles, visible white-out, erasing, etc.
  • Brochure uses at least 6 colors in design. Neat, with few visible corrections.
  • High degree of creativity, humor, and originality
  • Grammar & Spelling: Fewer than 2 errors
  • Rubric Rubric Attached, 10 Organelles included

Total Points Awarded: / 70 possible points

Digital Microscope Lab

Today classes began the Digital Microscope Lab.  We will finish this on Monday.

If you are unable to capture an image and send to me Monday from your own microscope, you will need to use someone else's.

Please work on answering the questions - these will be due after the lab is complete (Probably Tuesday).  

We quickly go into different cell types and our second digital microscope lab, so having this skill is key!

Chapter 2 Test

Chapter 2 Test from Tuesday has now been handed back to most of you.  Several students were in this afternoon doing test corrections - I will be passing back the test on Tuesday at the earliest (depending on when students take the test).

Thursday, October 16, 2008

Thursday Plan

Yesterday, classes took notes on Cells: Form and Structure.  This aligns with section 3.1 in your book.  Today classes will finish up the notes and move onto the microscope pre-lab.

Third period is taking the Healthy Youth Survey.  As a result, third period needs to complete part A of the microscope lab after the survey/as homework and pre-read the lab before tomorrow.  

HOMEWORK: Flowchart the lab: Parts B, C, and D for tomorrow.  You will not be allowed to do the lab until this is done.

Friday, October 10, 2008

Upcoming Week

Monday we are doing Test Review.

Tuesday is Chapter 2 Test.
Macromolecules (carbs, lipids, protein)

Wednesday we start Chapter 3: Cells.

I'll be checking my email off and on all weekend if you have any questions!

Thursday, October 9, 2008

Grade Updates

All macromolecule worksheets and macromolecule quiz scores are now online.

I still have several test corrections and odds and ends which will be entered this weekend.  PLEASE check your bag/home/etc for any loose work.

Properties of Water Activity

Today (Thursday) you will all have some time to finish the properties of water lab.  Then we will jump into Water Notes, which will finish out the week.

Reminder: 2nd Period Notebooks Due Today

Tuesday, October 7, 2008

Tuesday: Catch Up Day

Test answer sheets were returned today.  Remember, if you want test corrections or your September Notebook Check on first quarter grades, you need to have them into the turn-in box BY THURSDAY.


Please pre-read the Properties of Water Lab Activity.  Prepare your lab book to make your diagrams.

Plan to take the Chapter 2 Test Tuesday, October 14th.  If you are struggling with the Macromolecule Worksheets (yes, there are two) PLEASE come in Thursday PM or Monday PM.

Monday, October 6, 2008

Think Again!

I hope you all had a meaningful experience during the Think Again assembly today.

Tomorrow we're finishing up the macromolecule worksheets.  The worksheets from Friday are due tomorrow.

Additionally, I hope you are working on your September Notebook Checklist!

Sunday, October 5, 2008

This Upcoming Week

I hope 5th and 6th period tests went well and all of you had an excellent and safe Friday and weekend.

Test Scores are already online for 1st, 2nd, 3rd periods. Tests will not be returned until all students have completed the test. Assessments are NOT ONLY FOR A GRADE. Assessments are for demonstrating what you know. Test-taking is a skill which many of you are still developing. Another thing to think about is that this class has a cumulative final. These are skills and content knowledge that you need to know now, and you need to know in January.

For this reason, portions of this test are available for test corrections. I will explain this further on the day tests are returned. You will have 1 week to complete corrections.

Tomorrow we are attending the THINK AGAIN program, put on by Eastside Fire & Rescue. The "Think Again" program addresses the issues of drinking and driving, lack of seatbelt use, alcohol poisoning, and reckless driving among young people. This presentation is explicit and graphic in nature. If you are not attending, it is important that your parent/guardian informs the school or myself ASAP.

Tuesday we will return to macromolecules. We will finish the worksheets, answer any questions, and you have a short quiz on what we have done so far.

Later in the week we will be completing a Properties of Water Lab Activity and be finishing up Chemistry of Life.

Tentatively plan on taking the Chapter 2 Test on Tuesday, October 14th.
  • Basic Chemistry (Atoms, Ions, Molecules)
  • Properties of Water
  • Carbon-Based Molecules
  • Chemical Reactions
SEPTEMBER NOTEBOOK CHECKS are due this week or next week, depending on which period you have biology:
  • First: Wed. 10/8
  • Second: Thurs. 10/9
  • Third: Mon. 10/13*
  • Fifth: Tues. 10/14*
  • Sixth: Wed. 10/15*
  • * Note that this may be altered - no notebooks will be due the day before the test.
This way I will be able to return the notebook to you the following day. HOWEVER, depending on your section, this may or may not fall before:

QUARTER 1 GRADES, which are due October 10th. If you absolutely positively want that to be included this quarter, you must have your Notebook to me no later than Tuesday after school. Similarly, Test Corrections may be done and turned in no later than Thursday 2:30pm to be included in Q1 Grades. If not everyone has completed the test, then you would have to come in and work on the corrections IN THE CLASSROOM before that time.

Wednesday, October 1, 2008

October 1st - 3rd, 2008

Thursday: Chapter 1 test!

Friday: You are doing a chemistry and macromolecule worksheet.
