How is oxygen produced?

Oxygen is made when plants work hard during the day, just like you work hard at playtime.

Imagine a plant as a tiny factory. Inside its leaves are tiny bubbles called chloroplasts. These bubbles use sunlight to turn water and carbon dioxide into sugar and oxygen. It's like when you mix ingredients in the kitchen, you get something new!

Once the oxygen is made, it goes up into the air. That’s why we can breathe easily during the day. The oxygen helps us take big breaths and run around like wild animals.

When plants are happy, they make a lot of oxygen, which means we get to play longer without getting tired!
