Properties are always the same for a substance. The ____________ of different substances are different.

Properties are characteristics of substances. Properties help tell substances ______________.

Properties do not depend on the amount of substance you have. Examples of properties are ________, texture, hardness, and malleability.

When you ___________ across a bridge, you probably care whether it is made of aluminum or a stronger metal.

Properties of materials matter in many ways— to ___________ and to other people.

When people want to make something, the _____________ of the materials they use are important.

Substances (whether solids, liquids, or gases) have different properties; they are made up of ___________ particles.

Properties are characteristics of materials that scientists use to describe materials.

Properties are a unique way to describe materials because they remain the same— the amount (mass or volume) of the material is not important.

Scientists refer to the smell of a particular material as an odor. __________ is one property.

There are many other properties such as color, hardness, and so on. Odor helps to detect matter.

By identifying the smell of matter, it helps us to understand more about matter. Not all things have an odor, just like not all _______________ have a color.

Each material has a unique set of properties.

In Lesson 6, you saw two clear, colorless liquids. How could you tell them apart? (They had different odors, and they changed the _________ paper different colors— one red,

the other blue.)

How could you tell that gases that all look clear and colorless are actually different?

Why do different materials have different properties?

Different materials can have some similar properties (color) but they must have some different properties.

Properties can be used to distinguish one material from another.

Sometimes it is difficult (or impossible) to determine whether substances are the same by looking at them; more scientific methods and indicators are needed.

Which of the following best describes a gas?

Which state of matter does this image best represent?

What does an object's characteristic properties include?

Which of the following is a characteristic property of matter?

What is the formula for density?

Is color a property?

I am anything that has mass and takes up space!

To use the e- nose, a

patient exhales into an oxygen mask connected to it.

Bacteria colonies are made of particular types of molecules. They also have characteristic odors, so they have a “smell print” similar to a fingerprint.

Doctors can find it challenging to detect sinus infections. A sinus infection and pneumonia have different smell prints because they are made up of different ________________.

When you ride across a bridge, you probably care whether it is made of aluminum or a stronger

metal. Properties of materials matter in many ways— to scientists and to other people.
