Today we want to show you an experiment we did some days ago, when we were learning the Musculoskeletal System.
First, pupils were asked to bring bones in class. Attention! These bones had to be cooked, cleaned and frozen, for our safety work.

| We could also see some cartilage. |
 |
| Ariadna brought an enormous pig bone! |
Once we had all the bones (most of them, chicken bones), we classified them into 3 groups:
LONG - SHORT - FLAT
After that, we broke a bone to see what it has inside: THE BONE MARROW; responsible for making blood cells.
Then, we put some bone in a jar full of white vinegar, and we waited for 2 weeks.
What happened to the bones when we opened the jars after 2 weeks?
