• solid, liquid, plasma

• mass, temperature, volume

• solid, liquid, gas

The amount of matter in an object (measured in milligrams, grams, or kilograms)-

• density

• mass

• solubility

Objects that are more dense than water--

• float

• sink

• neither float or sink

A student is conducting an investigation using different objects in water to compare density. Each object is placed in a beaker that contains the same amount of water. Which statements are supported by this investigation?

Select TWO correct answers!

• A coin can be classified with Object 1 because both have a density equal to liquid water

• An ice cube can be classified with Object 2 because both have a density less than liquid water.

• A glass marble can be classified with Object 3 because both have a density greater than liquid water.

• A concrete block can be classified with Object 1 or Object 2 because the block has a density less than or equal to liquid water.

• A feather can be classified with Object 2 or Object 3 because the feather has a density that is greater than or equal to liquid water.

To measure solubility, you need...

• a magnet

• a scale

• water

A student is classifying objects. Answering which question will provide the best evidence that an object is a metal?

• What is its mass?

• What is its physical state?

• Does it conduct thermal energy?

• How quickly does it dissolve in water?
