Hello boys and girls, welcome to a new natural science unit, unit number 5, matter and heat. 00:00:02
Goal number 1, discover the properties of matter. 00:00:12
Goal number 2, we are going to learn about the three different states of matter, solids, liquids and gases. 00:00:19
goal number three we're going to discover changes of matter goal number four we're going to learn 00:00:29
about pure substances and mixtures and finally goal number five we're going to find out or 00:00:40
discover about heat. First question. What is matter? Can you see it? It's matter. Can you 00:00:52
touch it? It's matter. Can you smell it? It's matter. Can you taste it? It's matter. Everything 00:01:05
in our planet is made up of matter. Everything in the universe is made up of 00:01:17
matter. Living things are made up of matter, for example, animals, plants, the 00:01:28
five kingdoms. Non-living things are made up of matter, for example, water, rocks, the 00:01:37
ground or materials. What is matter then? Matter is everything that exists. All 00:01:46
materials are made up of matter. Natural materials are made of matter and 00:01:56
artificial or man-made materials are made up of matter. Let's become a 00:02:03
scientist an experiment to understand matter. As you know in class we've made a 00:02:10
few experiments to understand the properties of matter. Properties of 00:02:18
matter. Matter possesses or has two fundamental properties. Volume. Volume is 00:02:23
the space that a thing occupies. And mass, mass is the quantity of matter that thing has. 00:02:33
Volume can be measured in cubic meters, cubic decimeters, cubic centimeters. And mass can be 00:02:44
measured in kilograms, grams, milligrams. In class we made two experiments to 00:02:55
understand the properties of matter. First we had a rubber ball and a metal 00:03:04
ball and we asked two questions. Which side has more volume the rubber ball or 00:03:09
the metal ball and more mass? We had to make a hypothesis. The ball has more 00:03:17
volume and another hypothesis the ball has more mass and the results 00:03:25
were that the rubber ball has more volume and the metal ball has more mass 00:03:33
in this case. In experiment two we compared alcohol and water. We have to be 00:03:39
in mind that they both have the same level of liquid. In that case we have to 00:03:47
make a hypothesis alcohol or water has volume and hypothesis 2 alcohol or water 00:03:55
has mass. The result number one was that water and alcohol have equal volume or 00:04:05
or space in this case as the level of liquid is the same result number two was that water has 00:04:15
more mass than alcohol and we will also answer that alcohol has less mass than water 00:04:23
