In 6th Grade, we are studying the Musculoskeletal Sytem. Last week we did an experiment with bones, to learn how they can be and some of their characteristics.
Some children brought bones in class. They had to be already cooked and properly cleaned. First, we classified them into:
LONG - SHORT - FLAT
Then, the teacher broke some bones in order to relise that they are hard and to see what there is inside.
Days later, after some investigation, we discovered that they have the BONE MARROW inside:
The second part of the experiment consisted of putting bones into a jar and covering them all with vinegar.
We left there for a week and.... what happened????
Bones became flexible!!! Why?
