Matter STAAR Review

The table lists some physical properties of two objects. Based on their properties, which of the objects is most likely made of iron?

• Object 1, because it is a solid

• Object 1, because iron is magnetic

• Object 2, because metals always float in water

• Object 2, because iron is solid and non-magnetic

Objects that float in water are less dense than water. Objects that sink in water are more dense than water.

A student put four objects in a beaker of water. The objects are listed below.

Which two objects are most likely more dense than water?

• copper key and plastic ball

• wooden cork and plastic ball

• glass lens and wooden cork

• glass lens and copper key

A teacher poured 3 liquids into a glass. Then the teacher added 3 objects to the glass. The diagram shows where each substance stopped. Which liquid is most likely corn syrup?

• Liquid Z because corn syrup is more dense than water

• Liquid Y because corn syrup is more dense than water

• Liquid Y because corn syrup is less dense than water and more dense than a sponge

• Liquid Z because corn syrup is less dense than water
