How are you?
This week, many of you brought bones in class in order to make an experiment.
First, we observed and classified them into LONG, SHORT or FLAT bones:
Then, we broke some of them in order to answer the question: What's inside a bone?
We found out that bones have BONE MARROW inside, which something related to blood cells, but we have to investigate a little more...
Finally, we put the bone into a glass jar and we filled it with vinegar...
Now, we are going to wait for a week.
What is going to happen????? Any hypothesis???
