science week: soft shelled egg

i had mentioned earlier that i had wanted to do little lessons with the kids this summer. both to keep garrets brain ready for school and help me get through the long days. we had science week and the kids LOVED it. each day we did a little experiment. i wanted to share some of them because maybe your kids would enjoy them as well. this one was called the soft shelled egg. you can find lots of lesson plans on this idea, here is one http://www.education.com/activity/article/speakaboo-see-through-egg/we talked all about how experiments need ingredients or supplies... here is lynnsey helping rae pour vinegar over the egg.
we took nots and wrote down vocabulary words. garret really doent like to write but this was good practice for him. some words we learned were, acid, chemical reaction, and calcium carbonate.
here is the chemical reaction starting to take place. i am not going to write out all the details as you can just click the link above.
garret, proud of his science notes!
it worked! after 24 hours of the egg soaking in vinegar (an acid) we turned a hard shelled egg soft by producing a chemical reaction and dissolving the calcium from the egg shell. the kids thought this was so great. i thought it was pretty cool too.

What a neat idea: Science week! My kids in school always thought science was the best...and I can see that same love in your kids' eyes!

PS. A cool experiment to do is called the Cats Meow. Put milk in a shallow dish. Put a drop of red, yellow and blue food coloring in it (at like points of a triangle). Then have them dip the end of a toothpick in dish detergent and then stick into center of dish. It makes fireworks of color in the milk. very cool!
