Once upon a time, there was a little body named Bob. Bob had many important systems that helped him live a healthy life. One of these systems was the respiratory system, which helped him breathe and get oxygen into his body. Another was the skeletal system, which gave him a strong frame and allowed him to move and play. And lastly, there was the reproductive system, which would help him have children one day when he was grown up.

Bob loved learning about all his systems and how they worked together to keep him healthy. He went on many adventures and tried new things, always taking care of himself so that his systems could work properly. He was grateful for all that his body could do, and he promised to take good care of it every day.

The end.

3. Why is the skeletal system important for Bob?
4. What will the reproductive system help Bob do in the future?
5. What did Bob promise to do every day to take care of his body?
