2. What parts of flat bones and long bones are not as hard as compact bones?
3. What are the softer parts of bones called and how did they get their name?
Level#2

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 spaces 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 do spongy bones provide to for bones they are found in?
2. What do the spaces found in spongy bone form?
3. What are the spaces in spongy bone filled with?

Although they are softer than compact bones, spongy bones are quite strong. The spaces 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 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. What are the centers of flat bones filled with and what is produced in them that the body uses constantly?
2. Explain one major difference between red and yellow marrow, and where specifically yellow marrow is found.

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. Nutrients and oxygen are necessary for living bone cells to survive, where do they get it from?
2. What does the membrane of a bone have that carries blood to it, so it can get the oxygen and nutrients it needs?
3. What is a bone covered with?
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.

Level #1
Bones are made of both living and nonliving materials. The living materials are bone cells, blood cells, and nerve cells. These cells make up about one-third of bones.
1. Name the two types of materials that bones are made of.
2. List the three types of cells that make up the living materials of bones.
3. What makes up one-third of bones?
Level #2
Bones are made of both living and nonliving materials. The living materials are bone cells, blood cells, and nerve cells. These cells make up about one-third of bones. About two-thirds of bones are made up of nonliving materials, including the minerals calcium and phosphorous. The skeleton of an unborn baby is made of cartilage. This tissue is tough but flexible.

As an unborn baby develops, most of its cartilage skeleton changes to hard bone. The cartilage that is left has many functions. For example, it prevents the ends of bones from rubbing against each other.
1. Describe the materials that bones are made of.
2. Explain the nature of the two materials that bones are made of.
3. Explain what the skeleton of an unborn baby is made of, the nature of the tissue that makes up its skeleton, and what happens to the tissue as an unborn baby develops.
