SCIENCE ROCKS!

Today was a science day for me.  For the second year I am working on our schools science curriculum.  We do approximately 60 experiments each year, all of which have to be researched, documented into a lesson plan and of course done, to make sure they work!   I just wrapped up last years science documentation review so now I can begin year number 2.  We decided to do two years worth of experiments so that we can be on a rotation to keep it fresh for the kids.  I really can't express how much I enjoy science.  The kids faces when doing some of the experiments are priceless and if I can spark a bit of interest in the subject at a young age, then wow, what a bonus!

Here is a simple experiment you can try at home called "The Knotted Bone".

• Take some thin chicken bones and drop them in vinegar for a day or so until they become very soft & pliable
• Now you can tie them in a knot, just like a piece of string.
• Leave them sitting out on the table and they'll get hard again!  Or for a good experiment try putting it in milk?  Does it re-harden?

Vinegar is considered a mild acid, but it is strong enough to dissolve away the calcium in the bone. Once the calcium is dissolved, there is nothing to keep the bone hard.

What a great way to show kids why they should drink more milk!
