Why did the chicken cross the road?

This riddle first appeared in 1847 edition of a New York City magazine - The Knickerbocker.

The obvious answer is "to get to the other side of the road."

Isaac Newton said  "Chickens at rest tend to stay at rest. Chickens in motion tend to cross roads."

Do you have any other answers?

Before you start you need to consider...

Having an incubator in the classroom is big responsibility. I found the following BC SPCA position statement after starting the incubation of the chicken eggs in my class.

The BC SPCA has the following concerns when hatching eggs in the classroom:

• Hatching eggs in an incubator is not natural.
  
• How do you know that the egg(s) are fertilized before putting them in the incubator?
  
• Eggs are a commondity - a raw material or primary agricultural product that can be bought and sold. Is this what you are discussing?
• What happens if the power goes out? Do you have a backup power system? The temperature and relative humidity would change with no power.
• Can you garantee the eggs will hatch while you are at school? What happens if they hatch a Friday night and there is no one there to look after them until Monday morning?
• Does the teacher have expertise in hatching eggs?
• If you are video streaming -- why can you not put the camera(s) on the farm?
• The 'cute' factor. All new born animals are cute and this is engaging -- but how is this educational?

These are some of the questions a school and teacher must consider before starting a hatching program in the classroom. 

The following is a response to a ≈2005 'feel good' news paper article about hatching eggs in the classroom. The article was in the Peace Arch News. Sorry I do not have the exact date or link to the article.
  

There is a delicate balance when it comes to the use of animals in the classroom. Though the intentions to give students hands on experience are good, underlying lessons about devaluing animals for human benefit purposes can also be learned. Is raising chicks in an artificial environment really necessary to demonstrate life cycles to preschoolers? Could they not learn this through a video and a visit to a farm? A mother hen cares for her eggs very differently than a human does with an incubator. 

Understanding the care and natural instincts of a mother hen with her chicks is an important part of the equation completely underestimated when hatching chicks in an incubator. Yet it can be more compelling than the actual hatching, which may or may not happen when the students are at school. 

If we continue to use animals for science, in zoos and aquariums under the guise of education, are we reinforcing the idea that it is ok to deprive animals of a natural environment, family bonding, etc as long as humans are entertained and are “learning”. Is providing the students with a live action “birth” more important than the lives put at risk through incubation? It may be more exciting, but what is the real message. 

Encouraging students to think critically about how and why we use animals in society as well as developing empathy for animals by thinking about these situations from an animal’s perspective, might be a more educational experience and fit in more directly with the new BC curriculum. 

The BC SPCA’s position on hatching and breeding programs in the classroom states: “The BC SPCA opposes breeding and hatching programs in schools that include incubation and artificial environments. These animals require specialized care and a calm environment generally not provided in a classroom.” 

Animals are such an important part of our lives; the educational lessons we pass along to future generations should not be clouded with lessons we have inherited from the past.

What are the learning outcomes for the activity? Is there a better way of accomplishing the outcomes that will benefit the students and not harm the animals?

In this video, you will see a why there are different size of chicken eggs; how to determine if an egg is fertilized; and some of the differences between a store bought eggs and farm eggs.

Learn how to create shimmering hummingbird feather

At the Vancouver Learning Network, I teach a variety of classes (photography, physics, biology, jr. sciences, digital media and computer science). I came across this lesson that might be interesting to students in digital media -- it is on how to create feathers with Adobe Illustrator. Click here to view the lesson.

Ducklings

Raquel brought in some ducklings this afternoon. They are about 1 week old.

They are Muscovy ducklings. Here is an image of a parent Muscoy duck.

Day two - first live stream

Today we are live streaming the eggs. The stream will be available for a couple of hours. Liam a John Oliver student, in the next few days will explain how to create a live stream.

Day One

Today we put in 12 eggs into the incubator. The incubator should be a constant temperature of 99.5^oF and have a relative humidity of 44.5^oF.

Why does the temperature have to be 99.5^oF?

How many eggs does a hen lay in one year?

How many days before the eggs will hatch?

What type of chickens will hatch from the eggs that we have?

What is relative humidity?

Why is there a bottle of water behind the incubator?

Here is a sibling that was hatched naturally today.

Look for these answers and more fun facts in the next week.
