Bones (6th Grade)

Hello children!

Some days ago, pupils were asked to bring bones in class. Attention! These bones had to be cooked, cleaned and frozen, for our safety work.

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 bones 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?

We found out that bones could be easily bended! But, why?

Vinegar is an acid, so it dissolves away the calcium in the bones. When the calcium is dissolved, the bone isn't hard.

This is the reason why it is so important to eat calcium (milk, yogurt, cheese,...). The calcium we eat, goes to our bones and makes them stronger.

"Evolution" game (6th Grade)

Hello children!

How are you?

In 6th Grade, we are learning the Musculoskeletal System (bones, muscles, joints, ligaments, tendons, etc.). Isaac, a pupil from 6th B, suggested us an online game which is closely related to this topic.

This game is called Evolution:

Bones (6th Grade)

Hello!

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!

Bones, part 1 (6th Grade)

Hello 6th Grade!

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???
