Hi children, how are you? How are you today? I hope you are well, you are fantastic. 00:00:00
I want to start the class doing a short review about last day. 00:00:06
As you know, in the last class we started the genitree all about matter and machines. 00:00:10
One of the contents to remember is the meaning of matter and its properties. 00:00:17
You must remember that matter is everything around us that has mass and volume. 00:00:22
What's the meaning of volume? Volume is the space that an object occupies. And we must measure the volume in liters. On the other hand, we have the mass. What's the mass? The mass is the amount of matter in an object. 00:00:33
we should measure the mass in grams or kilograms. 00:00:59
OK, let's start with the new part of this term number 3. 00:01:07
Types of matter. 00:01:17
Matter can contain only one substance, like water. 00:01:19
We call this a pure substance. 00:01:24
Matter can also contain two or more substances, like in a creme caramel. 00:01:27
We call this a mixture. 00:01:36
In heterogeneous mixtures, we can see the different ingredients and separate them, like in a salad. 00:01:39
In homogeneous mixtures, we cannot see the different ingredients, like in lemonade. 00:01:49
Pools. You have to study this glossary, okay? Don't forget it. Amount is the quantity of something. Pure is when we don't mix a substance with another one, with anything, okay? Scales, an instrument for finding the weight of something. 00:01:57
