Ch. 10 Lesson 2

How are properties of matter

measured?

Object Prediction of mass (g)

Actual mass (g)

toothbrush

metal spoon

plastic bag of spoons

plastic toy animal

block of wood

flashlight

Activity-Find the mass of objects

mass•amount of matter an object has

•same no matter where the object is

gram (g)•metric unit for mass

•1,000 g = 1 kg

balance• tool used to measure mass

Comparing Mass [02:55]

What tool do we use to measure the mass of

an object?

•A balance.

What is the metric unit for mass?

•A gram.

What is the amount of matter an object has?

•mass

Fill in the blanks.

• The more ______ an object has, the greater its ______.

matter

mass

Object Prediction of volume (mL)

Actual volume (L)

Marble 10mL 7 mL

Light Colored Rock 7mL 10 mL

Dark Colored Rock 8mL 5 ml

Activity-Find the volume of objects

volume•amount of space that an object takes up

•use a measuring cup or graduated cylinder

tools used to

measure volume

measuringcup

graduated cylinder

liter (L)•metric unit of volume

•1,000 mL=1L

Measuring volume

What tools do we use to measure the volume

of an object?

•measuring cup & graduated cylinder

What is the amount of space an object takes up?

•volume

What is the metric unit for volume?

•A liter.

1,000•_______ mL=1L

density• measure of amount of matter in a certain amount of space

• spoon-–Mass = 35 g–Volume = 5 mL

Which has more mass?

Which has more volume?

Which has greater density?

Which liquid has the greatest density?

• Red colored water• Yellow corn syrupYellow corn syrup• Blue Vegetable oilI know this has the greatest density

because ________.Out of the 3 liquids, the one with the

greatest density was the ____.

buoyancy

• how matter floats in a liquid or a gas
