Ch. 11 , Lesson 1( properties of matter )

How do we describe Matter? • is any thing that takes up space and has mass.

you are made of matter, your book, pencil, anything you can name is made of matter.

Vocabulary:MatterPropertiesVolumemassObjectives:I will be able to know:1-Explore and observe matter .2-Define the terms matter and mass.3-Describe matter by its observable properties.

The world is full of many kinds of matter.How can we tell about them??Matter can be described by its properties. a characteristic of matter that you can observe.


property

5


Some properties you can observe by your sense of sight:Color, shape, size.You can also observe texture and luster. How an object feels.

How an object shines in light.

• Tell properties for each object:

7


Volume and Mass• Is how much space an object takes up.Ex. the beach ball has greater volume than the bowling ball.


volume

8


Is how much matter is in an object.Object with large mass feels heavy.

Object with small mass feels light.

However the bowling ball has more mass than beach ball.


mass

9


How do we measure Mass and Volume? Large objects don’t always have more mass than small objects. the bowling ball has more mass than beach ball?

Matter is made of very tiny particles.In some objects the particles are close together.In other objects they are farther apart.


10


the particles in bowling ball are packed together tightly.

They are packed more than the beach ball.


11


Matter with tightly packed particles are called dense matterMatter that is dense usually sink in water.Matter that is less dense will float.


12


To measure mass we use unit called gram.1 gram = the mass of 2 paper clips.We can use g to stand for the word gram.To measure the more massive objects we can use kilogramKilogram=1000 gramTo measure volume we use literWe can use L to stand for the word liter.


13


How are Mass and Weight related?The more mass an object has, the more it weights.If you visit the moon your mass will stay the same (the matter inside you wouldn’t change)However, you will weight much less(weight depends on gravity)Weight is the pull of gravity between you and Earth.The pull of gravity on Moon is weaker.


14


Weight is a force so it can measured in newtons.


Earth

weight 58 N

mass 6 Kg

Moon

weight 9 Nmass 6 Kg
