The Properties of Matter

Essential Questions: What is Matter?What is mass?

What is volume?

ObjectivesDescribe the two properties of all matter.

Identify the units used to measure volume and mass.

Distinguish between mass and weight.

Matter

Matter is anything that has mass and takes up space.

It’s that simple! Everything in the universe that you can see is made up of some type of matter.

What do all these things have in

common?

They are all made-up of MATTER!

What ismatter?

Anything that has mass and takes up space

Everything you see: boats, cars, people

Some things you cannot see like air

Matter and Volume: The amount of space taken up, or occupied, by an

object is known as the objects volume.Liquid Volume Liters (L) and milliliters (mL) are

the units used most often to express the volume of liquids.

Measuring the Volume of Liquids -We will use a graduated cylinder instead of a measuring cup to measure the

volume of liquids. The curve at the surface of liquid is called a meniscus.

The space taken up by an object.

Two objects cannot share the same space.Ex: Air and Water in the quick lab

What isVolume?

Quick Lab ReviewQuick Lab ReviewCan water and air both occupy the inside

of a cup at the same time?As a lab group, review the results from

your experiment.Continue your discussion on why the

towel was the way it was AFTER your experiment. Can you now use science to support why the towel was dry?

Teacher shows what happens if there is a place for matter to escape.

What materials

are used to measure volume?

Graduated cylinders and beakers. Liquid in these have a meniscus curved water line

Read the bottom of the curve for accuracy

Define and Draw the meaning of: Meniscus

Define: Meniscus is the curve at the surface of liquid.

Draw:

Meniscus

What unit is

Used to Measureliquidvolume?

Liters (l) and milliliters (ml)

Volume of a Regularly Shaped Solid Object The volume of any solid object is expressed in cubic units. The word cubic means having three dimensions.

Volume of an Irregularly Shaped Solid Object You can measure the volume of any solid object by measuring the volume of water that the object displaces.

How is the Volume

of a RegularlyShaped object found?

Multiply the three dimensions of the object

volume = length x width x height or v = l x w x h

units used will be cubic meters (m3) or cubic centimeters (cm3)

How is thevolume of an

Irregularlyshaped object

found?

Water displacementmethod drop an object in

aknown volume of water (30 ml) the water level

will rise(40 ml) The differencebetween the 2 levelsrepresents the volume ofthe object: 40 – 30 =

10ml1 ml = 1 cm3 both can

represent volumeAlmost always liquids in

ml and solids in cm3

Quick LabIn your Science binder, start a new page titled:Quick Lab. Finding the Volume of an Irregular Object.

Using what you have learned today, set-up a quick lab that allows you to measure the volume of the marbles at your table.

WHAT WERE YOUR RESULTS?

Mass and WeightMass:

Mass is the amount of matter in an object.

Weight:Weight is a measure of the gravitational

force exerted on an object.

Measuring Mass and WeightMass Measurement:

The SI unit of mass is the grams (g), but mass is often expressed in kilograms (kg) and milligrams (mg), too.

Weight Measurement: Weight is a measure of gravitational force and is expressed in the SI unit of force, the newton (N).

What is the differencebetweenmass and weight? video

Mass will stay the same for an object at any location

Mass measures an objects amount of matter

Measured in grams (g) or kilograms (kg)

Weight changes due to gravity’s force and distance of celestial body Planets, stars, etc.

Measured in Newtons and pounds

Review ObjectivesDescribe the three properties of all matter.

All matter has mass, volume Identify the units used to measure volume

and mass.The unit for Volume = milliliter (ml) or

cubic centimeter (cm3)The unit for Mass = kilogram (kg), gram (g),

and milligram (mg)

Distinguish between mass and weight.Mass is the amount of matter in an object.Weight is the gravitational force on an object.

Annotated reading assignment w/questions

Students work in partners, one reads while the other annotates:

Circle or underline words you do not understand.

Write any questions in the marginsAfter reading one paragraph students stop,

discuss and summarize, especially if there are words or phrases circled/questions in margins

For each paragraph switch jobs. After all of reading and discussion is complete begin questions. Take turns recording answers in space provided. Highlight the answer in the text and notate on the answer paragraph # and sentence # where found.
