 So today's experiment is how does a leaf breathe? All right, welcome back to Kids on Science. Today's experiment is very fun and easy and it costs zero dollars, right? So we're going to find out how does a leaf breathe? And so we're going to show you in this experiment how a leaf actually releases the oxygen. And so we're going to go through this and show you the setup and the science behind it right after this. All right, what you need for this experiment is you need freshly picked leaves. And I have a snowball leaf, an orange tree leaf, and a lilac leaf. So you want to make sure they are picked right before you do the experiment. You need three bowls or a bowl per leaf. And then you need some warm water. So just get some tap water that's warm, pour it in so it's high enough just so the leaf submerges. And then you need some rocks to be able to hold the leaves down. And that's it right from there. And so I'm going to show you the experiment net and the science behind it. Hey, if you're new to this channel, remember to click that subscribe button and the thumbs up if you like this experiment. So the setup's pretty easy. You take warm water and you pour it into the number of bowls, depending on the number of leaves you get. Just fill up just about enough so it's to be able to cover the leaf. So the next and last step is to take your leaf and place it in the water and put a small rock or stone on top of it so it's fully submerged into the water. And let it sit about two hours, one to two hours. So I'm checking after the first hour and you can see our lilac bush has small little bubbles coming out there. The orange tree has a little bit of bubbles. And then the snowball bush is hardly any after the first hour. So here's hour number two. We're checking back and you can see there's a lot more bubbles coming out, a lot more oxygen, which is pretty cool. So the science behind this is the plants help us breathe by taking in the carbon dioxide, the photosynthesis, by letting out the oxygen through their leaves. This process is called respiration. The leaf uses sunlight during the photosynthesis, which is where the plant converts the light energy into the chemical energy for the plant. During the photosynthesis, the leaf gets rid of what it doesn't need, the extra oxygen and water, which you see this video here on how you can capture the water that's released. The oxygen is the bubbles that you see and these bubbles is the respiration in action. I hope you enjoyed this experiment. If you did, remember to click thumbs up and to subscribe.
