Density: The Relationship Between Mass and Volume
Density is a measure of how much stuff there is (mass) in a certain
amount of space (volume). Equal sizes (volumes) of different
substances will have different weights (masses). Changing the
physical property of size causes an object that normally sinks to float.

9
An object’s density can be calculated if we know it’s _______ and _________.
Density is measured using the unit grams per cubic
centimeter (g/cc).
To calculate density, we ________ the object’s mass by the object’s
volume

10
A golf ball has a mass of 45 grams and a volume of 40 cubic centimeters
Density = Mass ÷ Volume
Density = 45 ÷ 40
Density = 1.13 g/cc
Water has a density of 1 g/cc.
An object with a density less than 1 g/cc will float,
but an object with a density
more than 1 g/cc will sink.

11
____________ is the ability of an object to float in water.
Key Questions:
1) What does density measure? How is it related to mass and volume?2) How can we measure the density of an object?3) What makes an object buoyant in water? How does this relate to the object’s density?

Physical and Chemical Properties of Matter
Physical properties of matter include its hardness and color;
chemical properties are identified by observing what happens when one substance
reacts with another.

Discovery Education Video:Physical Science Series: Properties of Matter
This program explores the many different characteristics of matter, including the chemical properties of matter, such as flammability and reactivity. It also examines some of the physical properties of matter including color, odor, texture, and shape, through beautiful visual images which students can easily understand. Much emphasis is placed on the concept of mass and weight. Volume and density are explored by looking at different types of matter such as gas, lead, marble, and feathers.
Physical Properties of Matter: Key Questions:
1) Why is understanding the physical properties of an object important?
2) Can an object’s physical properties be measured? Explain.
3) Why are a substance’s melting point and boiling point physical properties?

Lesson 4:Chemical Properties of Matter
What are Chemical Properties?
A chemical property is a characteristic of
an object or substance that can
only be observed or measured during a _______________.

A chemical ___________ is a process that changes the composition of a substance into a _______________.
Examples of _________ properties include:
FlammabilityToxicity
Heat of CombustionOxidation
Chemical StabilityAcidity / Basicity (pH)

Chemical Properties Key Questions:
1) How are chemical properties different from physical properties?
2) How can we tell when a chemical reaction has taken place?
3) Describe several examples of chemical properties
Lesson 5:Changes in Matter

The Law of Conservation of Matter and Energy tells us that matter and energy cannot
be __________ or ___________.But matter can be ___________!
Changes in matter can be classified as either _________ changes or __________ changes.

20
A _________ change is a change in matter that does not affect its
chemical composition.
After a physical change, a
substance may look different,
but it is still the _____________!
You can melt ice and then refreeze the water to make ice again. The ice
changes states but it is always water. You can tear up a piece of paper and it’s still paper. You can mix sugar in water and still taste that the sugar is there. These are all physical changes. Physical changes mean that matter has changed states but remains the same.

A ________ ________ is a process that changes a
substance into a _____________
through a chemical reaction.

You light a fire while you camp to keep warm and to cook. You also see a chemical change. Once the wood turns to ashes, it cannot turn back into wood. The wood has become something different. That’s what happens in a chemical
change.

Discovery Education Video:Changes in the Properties of Matter
Amanda’s friend Kyle is having trouble understanding matter, but she knows just the thing to do. She takes him to “A Matter of Fact,” an interesting store full of scientific things—and a peculiar storeowner to help them! Kyle learns all about the physical and chemical properties of matter, such as conductivity, magnetism, and combustibility. He finds out what mixtures and solutions are. Last, he learns about the physical and chemical changes of matter like rusting, tarnishing, and burning.
