Overview ...Over the next several weeks you along with your team will complete research into the embryonic development of a chick. To do this you will be guided through various challenges and will have to work as a team to ensure your success.
Because of the nature of school at the moment, this will be a truly ‘basement bio lab’ activity. Please note that the NEWER imformation is posted at the top of this website, BUT you should read all the information to ensure that you do not miss any clues!! |
Egg Weight DataHere is the Google Sheet (click) of the egg weights that were put in the regular incubator.
Individually you are to create a line graph with a line of best fit so that you can plot the progress of the eggs and the average. Remember that ONE is NOT fertile. Add to your line graph as data is provided . |
Sci 9 Hon. Major Project Final stages
The focus of this group project was the Core Competencies. By natural merit of the fact that you have been working in a group and developing strategies for communication you should have met the Core Competency of Communication. By working through the materials, discovering procedures and predicting outcomes you should have met the Core Competency of Thinking (Critical and Reflective).
Now you are ready to show what you have learned by presenting your final group project.
Followng are the instructions that will help guide you and your group to sucess. materials on our website before you begin.

Part 1: The reaction used
Your task is to write a balanced skeleton equation for the above reaction - work with your group. Place your answer at the bottom of the Groups Google Doc.
Part 2:
Unfortunately, the embryos in the shell-less culture did not survive. I can confirm that room temperature and Incubator temperature remained constant and there was still liquid in the cut for humidity. The yolk had thickened and the blood vessels were darker red.
Review the procedures on the project page with your group and try to see if there was any area withing the lab that could have been a weakness. Think of lab execution, conditions, procedures, etc. Your group's task is to answer the question - what could we do differently next time?
This should supplement my previous questions asking you to review the condition of the embryonic development.
Place your answer at the bottom of your group’s Google Doc.
Part 1: The reaction used
- To harvest elemental gas Oxygen I decomposed H2O2 (hydrogen peroxide).
- H2O2 (hydrogen peroxide) will decompose into H2O and O2 on its own, just very slowly.
- One reason H2O2 comes in dark bottles for storage is to slow this process, which is accelerated by light.
- A catalyst is used to speed up a chemical reaction. Light is an example that acts as a catalyst for H2O2 (hydrogen peroxide).
- To catalyze, or speed up the reaction, I added KI (Potassium iodide) to the H2O2. The KI isn’t changed as a result of the reaction and is not considered a reactant.
- We write KI above the “yields” arrow to show that it served as a catalyst in the reaction.

Is the devlopment matching your research?
Day 6 (Tues 19)
Some rapid growth is occurring.
Day 5 (Mon 18)
All factors remain unchanged.
Visable growth in embryo. |

Day 4 (Sun 17th)
All of the factors/variables remain unchanged.
Humidity averages in the mid 60% Temp 37.5 degrees Celcius.

Day 3
This is of Sat 16-5-2020.
Note that is day 2 of the shell-less culture (yesterday being the day they went in.

Day 2 (Fri)
Here are the DAY 2 notes...
- The temperature of the room was stable
- The procedure followed was the document below - download it and review it AS A GROUP. If you can not download it the doc, it is available online via a search of the title (A Novel Shell-less Culture System for Chick Embryos Using a Plastic Film as Culture Vessels).
- The images above show the process undertaken to create the culture vessel.
- 4 Vessels were created, 3 were a success, the fourth was unsuccessful as the egg yolk split (broke) and contaminated the vessel.

As an embryo develops it will become clearer what species it is. It is difficult at the early stages to tell though. Which one of the following do you think is human and which is a chicken?
Without realizing it you have already completed part 1, investigating the cell. Going forward we will review Asexual reproduction and sexual reproduction. In addition, we will look at the factors that support life on Earth.
Your challenge this weekend is to watch the video and begin looking on the internet for procedures, etc.
Your challenge this weekend is to watch the video and begin looking on the internet for procedures, etc.
I chose this video because if you look closely there are clues that you can follow up to find specific resources. This lab (from memory) is based on research from the 1970’s.
Your team is going to complete research. Note, there are multiple documents, etc. on how to complete this lab. You will decide on a procedure or create what you believe to be the best procedure for creating an artificial environment for an egg embryo to grow and develop. |

REMEMBER to record notes and resources. Remember that this will include our class website if you use it for researching bio. You will present your work in a little over a month. You will not be successful if you do not work as a group. Create and share with it each other (AND ME) a schedule/logbook in which you can record meetings, tasks, etc..
Your team will have to determine how best to communicate, but remember that you can use Google Meet along with your learn34 accounts. If you set up a link and share it it will remain open for 90 days.
Shell-less culture/artificial environment project - hints and guide.
You should now have contacted your group and be using the Google Doc I created for you to record what it is you are going to research and why. REMEMBER to put your name by the work you are going to do so others know who is doing what.
If you do not communicate with your group you will have trouble starting; it is often the starting point that is often the hardest part of any project.
REMEMBER …
Don’t overcomplicate it.
Think in a logical way
HINTS …
So there you go … divide up the work, record each persons ‘duties’ on the google doc. Find a time to meet (perhaps Google Meet), and get a document ready by Wednesday evening with detailed answers to the above questions along with a procedure you feel will work.
BUT … don’t stress, ALL of the basic answers are easily found online and ON OUR WEBSITE (review the slides/powerpoints in the Bio section).
And remember, if you need help you just have to email your group and then me.
Good luck

- If you take an embryo out of the shell how do you replace the shells function? You need to research what the purpose of the shell is.
- The embryo will develop. You need to complete research on the various stages of chicken embryonic development. How will you know that it is developing as it should if you don’t know what to expect?
- There are 2 basic parts to an egg, the white and the yolk. What is the function of each and how do they interact? Remember chickens are not like humans, they don’t get nutrients, protection, etc. from being inside their mother.
- Chickens reproduce sexually. What is a sperm and what is an egg? What is the process called that creates the sperm and the egg? What is the first cell called? After that first (one) fertilized cell is viable what is the process called that replicates cells? Go deeper, think where does the chicks DNA come from?
- And you need to complete research into how to complete the lab itself. Think of documents and videos online. The answers are out there. This is probably the biggest part of the project as there will be a lot of searching and reading.
