Last night we candled some of our eggs. To the right is what we saw in the white and brown eggs that have been incubating for a week, we couldn't see through the green eggs though. The eggs that had been incubating for almost 2 weeks we could clearly see the embryo's eyes, we could also see the embryos moving around. After candling the eggs it looks as if we will have a lot of chicks, there are only a few that we can't tell if the embryos are forming.
Here are some examples of what the eggs could look like. All we've seen so far are good eggs. We are eager to see what the eggs will look like at the end of the week.
Mrs. Pearson's class was wondering if you've heard of this science experiment with eggs:
ReplyDeleteTurn an Egg into a Bouncy Ball
1. Place the egg in the glass or jar.
2. Add enough vinegar to completely cover the egg.
3. Watch the egg. What do you see? Little bubbles may come off the egg as the acetic acid in the vinegar attacks the calcium carbonate of the eggshell. Over time the color of the eggs may change as well.
4. After 3 days, remove the egg and gently rinse the shell off of the egg with tap water.
5. How does the boiled egg feel? Try bouncing the egg on a hard surface. How high can you bounce your egg?
6. You can soak raw eggs in vinegar for 3-4 days, with a slightly different result. The eggs shell will become soft and flexible. You can gently squeeze these eggs, but it's not a great plan to try to bounce them on the floor.
That sounds fun, we're going to have to try that soon.
