How can you visualize the concept of volume?
By thinking of a juice box's capacity
If two objects have the same volume, what can still differ between them?
The amount of matter they contain
What is another unit of density besides g/cm³?
kilograms per liter (kg/L)
How much heavier is a kilogram compared to a gram?
A kilogram is 1000 times heavier than a gram
How does density compare between a steel ball and a feather of the same volume?
Steel ball has more mass
Steel ball is denser
Feather has less mass
Feather is less dense
What are the key characteristics of grams and kilograms?
Grams (g): small unit, weight of a paperclip
Kilograms (kg): larger unit, weight of a small water bottle
If a substance has a density of 1 g/cm³, how does it compare to water?
It has the same density as water
What is the density formula used for?
To calculate the density of a material
What units are used to measure volume in the density formula?
Cubic centimeters (cm³) or liters (L)
What does the symbol $ρ$ represent in the density formula? 
Density of the material
What units are used to measure mass in the density formula?
Grams (g) or kilograms (kg)
What is the approximate weight of a kilogram compared to a common object?
A kilogram is about the weight of a small water bottle
If an object has a density of 3 g/cm³ and a volume of 4 cm³, what is its mass?
12 g
What are the units commonly used for density, mass, and volume?
Density: g/cm³ or kg/L
Mass: grams (g) or kilograms (kg)
Volume: cm³ or liters (L)
Why is the steel ball denser than the feather?
It has more mass in the same volume
What is a cubic centimeter?
A small unit of volume
How does the mass of a steel ball compare to a sponge of the same size?
The steel ball has more mass than the sponge
How many cubic centimeters are in one liter?
1000 cubic centimeters
If a steel ball has a mass of 500g and a volume of 62.5cm³, what is its density?
$8 \text{g / cm}^{3}$
What can be inferred about two objects with the same volume but different masses?
The object with more mass is denser
How does mass differ from volume?
Mass measures matter, volume measures space
How can density be described in terms of matter?
It indicates how tightly matter is squeezed together
What is the definition of mass?
The amount of matter something contains
What is the formula to calculate mass using density and volume?
$m =$ $ρ × V$
What is the formula to calculate volume using density and mass?
$V =$ $\frac{m}{ρ}$
What units are used to measure volume?
Liters (L) and cubic centimeters (cm³)
Why is it important to use consistent units in the density formula?
To ensure accurate calculations
Why is a substance with a density of 2 g/cm³ denser than one with 1 kg/L?
It packs twice the mass into the same space
In the density formula $ρ =$ $\frac{m}{V}$ , what does $V$ represent? 
Volume of the object
When is kg/L typically used?
For liquids or larger things
What does density tell you about a substance?
How much mass is packed into a volume
How many grams are in one kilogram?
1000 grams
If a liquid has a density of 1 kg/L and a mass of 2 kg, what is its volume?
2 L
What should you do if the units are not consistent when using the density formula?
Convert units if necessary
How does the size of a liter compare to a cubic centimeter?
A liter is much larger than a cubic centimeter
What are the steps to calculate density?
Measure the mass in grams or kilograms
Determine the volume in cubic centimeters or liters
Divide mass by volume: $ρ =$ $\frac{m}{V}$
If a small steel ball and a large sponge occupy the same space, which has more mass?
The small steel ball has more mass
What does a density of $8 \text{g / cm}^{3}$ mean for steel? 
1 cm³ of steel weighs 8 grams
In the density formula $ρ =$ $\frac{m}{V}$ , what does $m$ stand for? 
Mass of the object
When is g/cm³ typically used?
For smaller objects, like metals
