Part One – What is Matter?What do these things have in common?

a scooter strawberriesyour teacher some books

All of these things are matter. Matter is all around you. Any object you can see, taste or feel is made of matter, including people, things, food and even water.

Here’s what you need to know about matter:

All matter takes up space. (This part is easy.)

AND

All matter has mass.

So, what is mass? Mass is how much matter an object contains. Objects that contain more matter have a higher mass.

Mass is measured in grams. We use a balance to measure mass.

Part Two– Matter is made of AtomsAll matter is made of very, very small parts called atoms.

Atoms are too small to be seen with your eyes or even a microscope.Different kinds of matter are made of different kinds of atoms. Some matter is made of only one kind of atom. Gold is made up of one kind of atom - gold atoms. Some kinds of matter are made of more than one atom. Salt is made up of two different kinds of atoms.

Part Three – Using Properties to Describe MatterHow would you describe these objects if you didn’t know what they were? Write your answers next to the pictures.(Hint: Use words that tell size, shape, color, or texture.)

When you describe objects by using:● size

● shape

● color

● texture (the way an object feels)

you are talking about an object's properties. A property describes how an object looks, feels, or acts. Different objects have different properties.

Part Four– Physical Properties of Matter

Size, shape, color and texture are not the only properties of matter. There are other properties of matter that can be measured without changing how matter looks - these are called physical properties.

When you look at oranges, you know that they are oranges because of their color, shape, and smell. You also know they are oranges because of their mass, volume, and density.We already know that mass is the amount of matter an object has. It is measured in grams using a tool called a balance.Volume is the amount of space an object takes up. Volume is also the amount of mass that a container will hold. Volume can be measured using a graduated cylinder. The unit of measure for volume is the liter.Density is another physical property. Density is the amount of mass in a given space.

Part Five– Chemical Properties of MatterChemical properties are different than the physical properties you can see just by looking at an object. Chemical properties are properties that can only be seen when matter changes.When a piece of paper burns, it turns into a black substance (ashes.) It no longer looks like paper. After the flame goes out you can no longer burn the new substance. This is because the chemical properties of the paper have been changed.Name:___________________________________________________ Date: _________________________

Listed below are several properties of matter. Use the T-list to sort the properties into physical and chemical properties. (Remember, chemical properties have to do with change.)

A jug holds two liters of water

Cherries are red Milk can spoil

A paper clip is three centimeters long

Paper can burn Sandpaper is rough

Physical Properties Chemical Properties

Part Six – Properties Can Change

Matter is constantly changing. Ice in your soda melts, glass breaks, paper is ripped. When ice in your soda melts where does it go? What does it become? When you drop the ice cube into a liquid, it begins to melt because the temperature is higher than that of the ice cube. It's like putting a snowman on your front lawn in July. The ice cube becomes liquid water.

This is an example of a physical change.The solid water turned to liquid water. It doesn't turn into soil or macaroni. It remains water. If it did change into soil or macaroni, your drink would taste terrible and you would have an example of a chemical change.

Chemical changes are when substances change into other substances. If it could happen, ice changing into macaroni would be an example of a chemical change. A real example of a chemical change is spoiling milk or burning toast. Milk needs to be in the refrigerator or else it will go bad. If you've ever seen or smelled spoiled milk, it is not a pretty sight. The milk gets a sour odor and becomes lumpy.

Unlike physical changes, you cannot reverse chemical changes. Once matter changes, it cannot go back to the way it was before. You can melt ice to get water and freeze that water to get ice again, but you cannot make milk unspoiled.
