Hi everyone. Today we're going to make some molecules by using some plasticine of different colors and some toothpicks.
00:00:01
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.
00:00:12
The two peaks will be the bones, or links, between atoms, so they can keep them together, forming the molecules.
00:00:28
First, let's start with the oxygen molecule, made up of two oxygen atoms.
00:00:40
So, oxygen, and we're going to form the molecule.
00:00:49
oxygen molecule. Now let's do the next one, ozone molecule.
00:01:00
To make this molecule we need three atoms of oxygen.
00:01:15
One, two, and three. We use the toothpicks, that's it.
00:01:20
ozone molecule. The third molecule is water, so we need two hydrogen atoms and
00:01:42
one oxygen atom, okay? So one and two and one of oxygen. You can notice the
00:01:55
triangle for water. And finally let's make the carbon dioxide molecule. We need
00:02:25
one carbon atom and two oxygen atoms. We use the toothpicks and we have it, we
00:02:36
have the molecule. So let's review all the molecules we've made. Oxygen
00:03:02
molecule, ozone molecule, water molecule, and carbon dioxide molecule. Thank you. I
00:03:10
hope you enjoyed this activity. Bye bye.
