Objective: Children will learn where the lungs are and what our lungs do when we breathe.
Breathing is something you do all day, every day, without even thinking about it! You have two lungs, one on each side of your body, and they are large organs in your body. They help you take fresh air into your body and get rid of old air. Your lungs take up most of the space in your chest. Because your heart takes up some of the space on the left side of your chest, the lung on your left side is a little smaller than the lung on your right side.
Your lungs are an important part of your body. Air comes in through your nose or mouth and travels through your windpipe and into the lungs. The lungs take oxygen out of the air and pass it to the parts your body. You cannot see your lungs, but you can feel them in action. When you breathe in, or inhale, your chest fills up with air and expands. When you breathe out, or exhale, your chest returns to its normal size. Exercising is important for keeping your lungs healthy. Your body needs more oxygen when you exercise, so your lungs get filled with more air, and that lets them do their job better. They work harder to get more air to the rest of the body.
These lessons are aligned with the Common Core State Standards ("CCSS"). The CCSS provide a consistent, clear understanding of the concepts and skills children are expected to learn and guide teachers to provide their students with opportunities to gain these important skills and foundational knowledge.
