Matter Unit 1 North Carolina

Daniel, Isla, and Priya are in a science class. Their teacher asks them, 'What would you call something that has certain properties?'

• Anything that Daniel lifts and takes up space in the classroom.

• Anything that Isla can pour into a container and it takes up space.

• Anything that Priya measures its density and it takes up space.

• Anything that they can measure its mass and it takes up space in the classroom.

Charlotte, Kai, and Hannah are studying the properties of matter. They are trying to identify the three common states in which matter can exist. Can you help them?

• solid, liquid, and plasma

• solid, gas, and plasma

• solid, liquid, and gas

• plasma, liquid, and gas

Noah, Benjamin, and Ethan are discussing the difference between a solid and a liquid. What is the main difference between these two states of matter?

• The main difference between a solid and a liquid is the arrangement of their particles.

• The main difference between a solid and a liquid is their color.

• The main difference between a solid and a liquid is their temperature.

• The main difference between a solid and a liquid is their density.

Zoe, Oliver, and Anika are discussing the properties of liquids and gases. What is the main difference between a liquid and a gas that they should consider?

• A liquid has a fixed volume while a gas does not.

• A liquid cannot be compressed but a gas can.

• A liquid is always denser than a gas.

• The main difference between a liquid and a gas is the arrangement and movement of their particles.
