The amount of space that an object takes up or occupies.
100
What is the definition of Mass?
A measure of the amount of matter in an object.
100
What is the definition of Density?
The ratio of the mass of a substance to the volume of a substance.
100
What is the definition of weight?
a measure of the gravitational force on an object.
200
True or False? Lightning is matter.
False
200
How do you find the volume of a regular shaped object?
L x W x H
200
What tool is used to measure mass?
Triple-beam balance
200
What formula is used to solve for density when mass and volume are known?
Density=Mass/ Volume or D=M/V
200
True or false?
An astronaut weighs more on the moon than on Earth.
False. An object would weigh less on the moon because the moon has less mass and therefore exerts less gravitational force.
300
Name three examples of matter in the classroom.
Answers may vary. Possible answers: Table, person, pencil, etc.
300
How do you find the volume of an irregular shaped object?
Use a graduated cylinder to find the original volume and the volume after the object has been added. Subtract the two measurements to find the volume of the object.
300
True or false?
Air has mass.
True.
300
A block of wood has a mass of 120 g and a volume of 200 cm3. What is the density of the wood?
0.6 g/cm3
300
What tool is used to measure weight?
spring scale
400
How can you tell if something is matter?
If it has mass and takes up space.
400
Original Volume= 40mL
Final Volume= 60mL
What is the volume of the irregular shaped object?
20mL =20cm3
400
True or false?
A brick and a sponge are the same size therefore, they have the same amount of mass.
False. A brick has more matter therefore, it has more mass.
400
Length= 2 cm Width= 3 cm Height= 4 cm
Mass=48 g
What is the Density?
2 g/cm3
400
Is air matter?
Yes because air has mass and takes up space. Ex: empty balloon vs full balloon.
500
True or False?
Light is matter.
False. Light does not take up space or have mass.
500
Length= 5 cm
Width= 4 cm
Height= 10 cm
What is the volume of the rectangular object?
200 cm3
500
Density= 2g/mL
Volume= 6 mL
What is the mass of the unknown substance?
12 g.
500
True or false?
The density of a block of wood will change if the block is cut in half.
False. The density of a given object remains the same no matter how much of the substance you have.
500
Is it possible for an objects weight to change while its mass remains constant?
Yes, the mass of an object is constant while the weight of an object varies depending on gravitational force.
