6th grade density

Front

What is density?

Back

Density is the mass of an object divided by its volume, usually expressed in grams per milliliter (g/mL) or grams per cubic centimeter (g/cm³).

Front

How do you determine if an object will sink or float in water?

Back

An object will sink if its density is greater than that of water (1 g/mL) and will float if its density is less than that of water.

Front

If an object has a density of 3.6 g/mL, will it sink or float in water?

Back

It will sink because its density is greater than that of water.

Front

What happens to the density of an object if it is cut in half?

Back

The density remains the same regardless of the size of the object.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What is water displacement?

Back

Water displacement is a method used to measure the volume of an object by observing how much water it displaces when submerged.

Front

If an object displaces 25 mL of water, what is its volume?

Back

The volume of the object is 25 mL.

Front

What does it mean if an object is floating on water?

Back

It means that the object's density is less than the density of water.

Front

Which object is least dense if one is floating and another is submerged?

Back

The object that is floating is the least dense.

Front

How can you compare the densities of two objects?

Back

You can compare their densities by calculating the mass and volume of each and using the density formula.
