Hi everyone. Today we're going to make some molecules by using some plasticine of different colors and some toothpicks.

2
00:00:12,279 --> 00:00:28,140
First, we need to make the atoms. I'm going to use blue for the oxygen atom, red for the hydrogen atom, and green for the carbon atom.

3
00:00:28,140 --> 00:00:39,159
The two peaks will be the bones, or links, between atoms, so they can keep them together, forming the molecules.

4
00:00:40,479 --> 00:00:48,100
First, let's start with the oxygen molecule, made up of two oxygen atoms.

5
00:00:49,380 --> 00:00:59,509
So, oxygen, and we're going to form the molecule.

6
00:01:00,350 --> 00:01:15,230
oxygen molecule. Now let's do the next one, ozone molecule.

7
00:01:15,230 --> 00:01:20,230
To make this molecule we need three atoms of oxygen.

8
00:01:20,230 --> 00:01:42,019
One, two, and three. We use the toothpicks, that's it.

9
00:01:42,019 --> 00:01:55,890
ozone molecule. The third molecule is water, so we need two hydrogen atoms and

10
00:01:55,890 --> 00:02:25,830
one oxygen atom, okay? So one and two and one of oxygen. You can notice the

11
00:02:25,830 --> 00:02:36,389
triangle for water. And finally let's make the carbon dioxide molecule. We need

12
00:02:36,389 --> 00:03:02,800
one carbon atom and two oxygen atoms. We use the toothpicks and we have it, we

13
00:03:02,800 --> 00:03:10,759
have the molecule. So let's review all the molecules we've made. Oxygen

14
00:03:10,759 --> 00:03:23,900
molecule, ozone molecule, water molecule, and carbon dioxide molecule. Thank you. I

15
00:03:23,900 --> 00:03:28,840
hope you enjoyed this activity. Bye bye.
