Boys and Girls,
It has been health week in our blog for the last 2 weeks and what amazing activities we’ve had to explore different ways to keep healthy. Have you thought what our body does while you are doing all the challenges from the grid? Well, there is an important organ that keeps your body receiving oxygen so you can keep moving around.
Can you guess which organ I am talking about? Well done, the lungs.
Every time you do a physical activity your muscles and organs need oxygen so they can keep moving. When you breathe in, air flows through the blood going all around your body and then when you breathe out, you release it as carbon dioxide (something our body does not need). Do you know what organ pumps the blood all around our body? The heart. So every time you are running fast you will breathe fast and you will feel your heart pumping fast too, that is because they both need to keep up at the same level so you can do any activity you want.
Click the green link if you want to know more about this process, there are some activities you can do too: BBC Bitesize: How do humans breathe?
Do you want to see how lungs work inside us when we breathe? Let’s make our lungs then!
Materials
- 2 straws
- Scissors
- 2 plastic bags
- Sellotape
- Drawings of the lungs, mouth and nose.
Step 1
Tape the straws at the top and at the bottom as shown in the photo.
Step 2
Glue or double stick tape your nose and lips to the straws.
Step 3
Tape your bag to each lung, tightly so no air escapes.
Step 4
Tape your lung printable to the back of the straws. Like on the photo, now your lungs are ready!
Activities
Explore how your just made lungs work, you have to be very gentle. After you have tried them, can you explain:
- What happens when you breathe in (put your hand on your chest) and now try with the lungs you made.
- What happens when you breathe out (put your hand on your chest) and now try with the lungs you made.
- How do you know your body needs more air?
- Describe what happens to your breathing and your lungs when doing different exercises from the grid.
- Comment your thoughts, write them on your learning journal or add them to your sway.
