Measuring Matter

Match each term to its definition.

• a measure of the mass of a material in a given volume

• Density

• a measure of the force of gravity on the object

• Volume

• anything that gas mass and takes up space

• Mass

• a measure of how much matter an object has

• Weight

• a measure of the amount of space matter takes up

• Matter

What tool can be used to measure each?

• graduated cylinder

• mass

• balance or scale

• volume

• spring scale

• weight

In the metric system, mass is measured in ​ (a)   ​or (b)   , weight is measured in ​ (c)   , and volume is measured in ​ (d)   or ​ (e)   .

• grams
• kilograms
• newtons
• liters
• milliliters

Fill in the blanks with mass or weight.

The amount of matter in an object is called its ​ (a)   .

The force of gravity on an object is called its ​ (b)   .

Your ​ (c)   is always the same regardless of gravity.

Your ​ (d)   on Earth is different than on the moon.

On Earth, the ​ (e)   of an object is 10 newtons.

• weight

How do we calculate the volume of a cube or rectangular prism?

• we multiply the length by the width by the height.

  length x width x height

• We add the length and width together and then multiply by the height.

• We divide the length by the width and then multiply by the height.

• We multiply the length by the width and then add the height.

Order the steps of measuring the volume of an irregular shaped object.

• We put water in the graduated cylinder.

• We write down the volume of the water.

• We drop the irregular shaped item in the water.

• We write down the new volume of the water (with the object inside).

• We subtract the volume of the water from the new volume of the water (with the object).

We put a rock in a graduated cylinder containing 600 ml of water. The volume became 800 ml.

What is the volume of the rock?

• 200 ml

• 150 ml

• 400 ml

• 300 ml

Objects with densities greater than that of water will ​ (a)   ​ and objects with lesser densities will ​ (b)   ​.

• sink
• float

What happens if you shake a bottle of oil and vinegar?

• the oil will float above the vinegar because oil is less dense than vinegar.

• The bottle will explode.

• The oil and vinegar will mix together.

• The oil will sink down the vinegar as the oil is more dense than the vinegar.

• 5 g/cm3

• 0.2 g/cm3

• 2.5 g/cm3

• 9 g/cm3
