Level#1

Bones grow and change. Some cells help build bone tissue. Some cells break down bone tissue. When bone tissue is broken down, some of the minerals inside bones are released into the body for use. However, your body normally replaces those minerals with minerals from the foods you eat.

1. What happens to your bones as you change from being a child to a young adult?






2. When bone tissue is broken down, what happens to the minerals inside of bones?






3. How does your body replace the minerals from inside your bones that are released?








Level#2

Bones grow and change. Some cells help build bone tissue. Some cells break down bone tissue. When bone tissue is broken down, some of the minerals inside bones are released into the body for use. However, your body normally replaces those minerals with minerals from the foods you eat. The building up and breaking down of your bones changes the size and shape of your bones as you age. At some point in your life, you may go through "an awkward stage" because of the way your bones grow. The first bones to grow quickly are usually your foot bones. Then, your arm and hand bones grow quickly.

1. What two things do cells do to change bone tissue?





2. When bone tissue is broken down, what happens to the minerals inside of bones?





3. What are the three areas of the body that bone growth normally takes place first?










Level#3

Bones grow and change. Some cells help build bone tissue. Some cells break down bone tissue. When bone tissue is broken down, some of the minerals inside bones are released into the body for use. However, your body normally replaces those minerals with minerals from the foods you eat. The building up and breaking down of your bones changes the size and shape of your bones as you age. At some point in your life, you may go through "an awkward stage" because of the way your bones grow. The first bones to grow quickly are usually your foot bones. Then, your arm and hand bones grow quickly. Because of this uneven growth, arms, hands, and feet may look too big for the rest of the body. This does not last long. After a while, the rest of the body catches up.

1. Explain, what two things cells do to change bone tissue?





2. Explain, what happens when bone tissue is broken down and how the body replaces minerals bone lose during this process.






3. Explain, what causes "an awkward stage" in your development.
