Level#1

The centers of flat bones and the ends of long bones are not as hard as compact bones. These softer parts of bone are called spongy bone. They even look like sponges because they are filled with many spaces. The spaces are filled with connective tissue and blood vessels.

1. What is not as hard as compact bone?

2. What are the softer parts of bone called?

3. What does spongy bone look like?

Level#2

The centers of flat bones and the ends of long bones are not as hard as compact bones. These softer parts of bone are called spongy bone. They even look like sponges because they are filled with many spaces. The spaces are filled with connective tissue and blood vessels. Although they are softer than compact bones, spongy bones are quite strong. The space in them form a support structure that is lightweight. Spongy bones provide support to areas in bones where there is great pressure and stress.

1. What is not as hard as compact bone?

2. What are softer parts of bone called and what do they look like?

3. List three facts about spongy bone that are found in the above text.

Level#3

The centers of flat bones and the ends of long bones are not as hard as compact bones. These softer parts of bone are called spongy bone. They even look like sponges because they are filled with many spaces. The spaces are filled with connective tissue and blood vessels. Although they are softer than compact bones, spongy bones are quite strong. The space in them form a support structure that is lightweight. Spongy bones provide support to areas in bones where there is great pressure and stress. The centers of your bones are filled with marrow. Marrow makes blood cells. Marrow is red or yellow in color. Red marrow is actively makes red blood cells. Yellow marrow is not active. It is found in the center of long bones. Yellow marrow is made mostly of fat cells.

1. How do the centers of flat bones, and the ends of long bones, differ from compact bone?

2. What are the softer parts of bone called and what do they look like?

3. List three facts about spongy bone that would be important to know.

4. How is red marrow different than yellow marrow?

Level#1

A bone is covered with a strong membrane. This membrane has many blood vessels that pass through it. Blood supplies living bone cells with nutrients and oxygen.

1. What does the strong membrane cover?

2. What is passing through the membrane of a bone?

3. What is supply the bone with nutrients and oxygen?

Level#2

A bone is covered with a strong membrane. This membrane has many blood vessels that pass through it. Blood supplies living bone cells with nutrients and oxygen. Under the membrane is compact bone. Compact bone is made up of living bone cells. It is also made up of the mineral calcium. Calcium in compact bone makes it hard and gives it strength. A network of tubes also runs through compact bone. These tubes contain blood vessels  and nerves.

1. Describe what a bone is covered in.

2. Describe what passes through the membrane of a bone and what is supplied to the bone as a result.

3. Describe what is found under the membrane of bone and what it is made of.

4. What runs through compact bone and what does it contain?

1. Describe the composition of compact bone and its contents.

2. What do flat bones and long bones have in common?

3. How is spongy bone different than compact bone and what does spongy bone provide for bones that contain it?
