So this week in science we've been covering the skeletal system...everything bones! It's been a fun unit with lots of manipulatives and experiments. One of Zoey's experiments was to soak a bone in vinegar (an acid) and to see what happened.
The vinegar ended up pulling out the calcium from the bone and thus made the bones rubbery and bendable! Definitely not as strong. We let our chicken bones soak for two days...the small bones were completely bendable and the larger leg bone was soft and bendable on the ends. We think that had we kept it soaking for one more day it too would have been completely bendable like the smaller bones.
This was a super fun experiment and showed just how important calcium is to bones!
