The Incredible Egg

We soaked raw eggs in 4 different solutions for 4 days then observed the results.

Then we did this:

You really need to watch it in slow rewind after it is done to see the egg growth.

We also soaked a raw egg in vinegar of 2 days (the shell gets all soft because the vinegar pulls out the carbon dioxide from the egg.

Cool picture of egg in vinegar. The bubbles are the vinegar pulls all the carbon dioxide out of the egg.

When placed back on the counter the shell with pull carbon dioxide from the air and make the shell strong again.

In the middle is a regular raw egg the brown egg was just a white egg soaked in vinegar, the green egg was soaked in vinegar then in water with food coloring.

Even though the egg was rubbery and bouncy we took the green egg outside to drop and find out if it would bounce.

It went splat! Just like a water balloon. We did this at the end of our driveway those are seeds you see from the trees as well.

Food for thought: eggs are porous and easily absorb things from the environment "Some states require that all eggs receive a chlorine bath and mineral oil coating before they are nestled into their cartons" taken from the Mercola site. If you want to read the whole article on how even organic store bought eggs are not good for you click here. Support your local farmers and buy local! These experiments really helped Falcon understand how even organic eggs found at the grocery store are not as good for you due to the chemicals that get poured on them to clean them.

We got to meet Martha from the PBS Show Martha Speaks at a local library. It was one we had never been to before and it was so nice we will defiantly go back soon and it was right near a very cool graveyard with lots of very big gravestones. We did not have time to check that out but I plan on doing that soon. I do love graveyards!

We finished up our FIAR book and activities, Storm In the Night I will be blogging about that in a few days.

I am reading

It is a very good book I couldn't put it down. I did find it amusing that it was a Christian Novel and I am not Christian, but that didn't stop me from reading it! Very good read.

My wisdom of the week:
Children are my puzzles they keep me on my toes and whenever I think I have found just the right piece it turns out that it doesn't fit quite right and I have to search all over again. However, is quite rewarding when I do find a piece that fits just right!

Something else to think about: Eggs are laid with a wet coating that quickly dries. That coating, called bloom, is a natural barrier that the hen puts on her eggs to protect the insides from bacteria and other contaminants. Eggs don't have to be cleaned with chemicals or even water to keep out "bad stuff" because hens do it naturally for us!

sounds like you all learnt a lot this week :)

I like your piece about the puzzle :)

See Jamie blog said...

One of the reasons I like Christian romances because they aren't as crass as many romances tend to be.

Love all the experiments you did! We don't do nearly enough of those in our homeschool!

Great experiments! I just love fun, hands-on learning! Thanks for visiting my blog! :-)

This is my first time here - I think. We did the egg experiment last year, and I never even considered the purchased eggs ... and we buy the organic vegetarian - which doesn't mean squat really. THANKS for the reminder!
