Healthy body, healthy spirit, healthy mothering. This is the journey I have set out on with my two amazing children.

Nerdy like me?

The kids participated in this year's school science fair. Nevaeh really wanted to. Kelen HAD to. All 4th, 5th & 6th graders have to do a project as a major portion of their science grade. Here is Kel pouring vinegar into a glass jar. He chose to do "How different acids affect a chicken bone".

His 3 acids? 1. vinegar 2. grapefruit juice 3. coke


Day 2. None of the bones are bending.

Day 3. The bone in the vinegar is very slightly softer. He can't actually bend it yet but there is a noticeable difference in the texture of the bone. So cool!


Nevaeh chose "How to flote an egg" (her spelling obviously). She is stirring salt into regular tap water.


Tadaaaa! It also worked by dissolving sugar in tap water.


Day 4. The bone from the vinegar bends in half! The bone in the coke did not bend at all (although it was stained black ewww) and the bone in the grapefruit juice also became softer. I accidentally broke it at the end by bending a little too hard. I think with another day or 2 of soaking it would have bent just like the one in the vinegar. But like I said, Kel was NOT really into this experiment so he didn't want to put in the extra days. :(


He got an A.
