This last weekend we were able to look inside the forming eggs with a method called candling. Candling is when you light up the inside of an egg with a bright light, usually a flashlight, to see if your chicken is forming inside. It was amazing to see some of the little chicks wiggling around inside. Here are some pictures of what we saw.

Here is a picture of an infertile egg.

THis one has a chick forming at 7 days

This one is a “quitter” a chick that died early in development

We saw a defiant 7 chicks that were developing well and wiggling around in there.  One of those were from the smashed box of egg that I received! We also have had lots of fun this week with our egg experiments.

The raw egg /cooked egg test.

Place a hard-boiled egg and a raw egg on the table. Spin each of them and see what happens.

The raw egg spins slowly and wobbles and the cooked egg spins fast.  Why is this? Its because the liquid yolk and white are different densities. The boiled egg is one solid piece. Therefore the whole egg spins in the same direction. The raw egg has liquid inside which moves separately from the shel which keeps the whole egg from spinning quickly.

For part two of the spin test, get an egg spinning again, stop it with your hand, then quickly let go. If the egg stops quickly  it’s hard-boiled. But if it begins to move again after you take away your hand, it’s raw.

The  Egg in a Bottle test.

This one is fun to watch at any age. I know we performed it a few times 😉

What you will need is a peeled hard boiled egg and a glass bottle with a mouth a little smaller than the egg, I used a quart milk jar, paper and a lighter.

I first had my kids gently try see if they could put the egg in the bottle without breaking it.  They could not.  Light a piece of paper and stick it in the jar. Quickly place the egg on top and watch what happens.  The egg gets sucked into the bottle!

Why does this happen?

 In elementary terms, the burning piece of paper heats the molecules, or little pieces that you can’t see that make up air, in the bottle and causes the molecules to move far away from each other. Some of the heated molecules escape out past the egg. When the flame goes out, the molecules of air in the bottle cool down and move closer together creating a suction like a vacuum.  If the egg wasn’t there the air outside the bottle would come rushing in to fill the bottle. The air trying to push its way back in is so strong pushes the egg into the bottle.

I love learning new things.  I also love teaching my kids about God’s world. We plan on candling again this weekend and will have more fun experiments to perform in the next few days.
