00:00:00,570 --> 00:00:13,610
Teacher: We have been learning about ways to describe matter. All
objects are made of matter, and can be made of solids, liquids or

00:00:13,610 --> 00:00:21,870
gases. What are objects made of?
Students: Solids, liquids, gases.

00:00:21,870 --> 00:00:30,400
Teacher: Very good. Okay. Matter is made up of anything that has
weight and takes up space.

00:00:31,500 --> 00:00:43,550
You can describe objects. When you tell about objects, this is called
properties. Properties tell us about objects. What do properties do?

00:00:43,550 --> 00:00:45,350
Students: Tell us about objects.

00:00:45,350 --> 00:00:52,720
Teacher: Very good. We can use our senses to tell us about objects.
Let’s review our senses.

00:00:52,720 --> 00:01:00,460
Students: Site, smell, hearing, tasting, touching.

00:01:00,460 --> 00:01:14,530
Teacher: Very good. An objects can be described by it properties,
such as its size. Is it big? Is it small? Its shape. Is it round? Is

00:01:14,530 --> 00:01:33,150
it rectangular? Its color. Is it red? Is it blue? Is it yellow? How
does it smell? Does it smell good? Does it smell bad?

00:01:33,150 --> 00:01:47,370
Length is another way that can tell us about properties of matter.
Remember all objects are made of matter and can be solids, liquids,

00:01:47,370 --> 00:02:09,200
or gases. Length measures the distance from one end of an object to
another. Length can be measured in centimeters or meters. We use a

00:02:09,200 --> 00:02:10,660
metric ruler.

00:02:16,910 --> 00:02:34,850
So, we can see from one end of the rolling pin to the next one is
45 centimeters. Now, scientists use meters, centimeters, and kilometers,

00:02:34,850 --> 00:02:45,150
and those are parts of the metric system. In the United States, we use
inches—like these little guys right here, these are inches; inches,

00:02:45,150 --> 00:02:59,400
feet and yards—but in science, the metric system is commonly used.
Let’s review our vocabulary words before we read from our textbook.

00:02:59,400 --> 00:03:06,100
The listening center is open for a small group of students to listen
to the book on tape. And we will work in our groups to complete some

00:03:06,100 --> 00:03:11,190
activities about matter and properties of matter.
