Unit Checkpoint: Matter Properties
Test Your Knowledge
Complete all 10 questions about matter and its properties.
Checkpoint Questions
Question 1
What are the three states of matter?
Show Answer
Solid, Liquid, Gas
Matter exists in these three common states based on how particles are arranged and move.
Question 2
Is cutting paper a physical or chemical change?
Show Answer
Physical change
The paper changes shape but is still paper - no new substance is created.
Question 3
What happens to particles when matter is heated?
Show Answer
They move faster and spread apart
Heat energy causes particles to vibrate and move more quickly.
Question 4
Is burning wood a physical or chemical change?
Show Answer
Chemical change
Burning creates new substances (ash, smoke, gases) that cannot be turned back into wood.
Question 5
What is mass?
Show Answer
The amount of matter in an object
Mass is measured in grams or kilograms and stays the same regardless of location.
Question 6
What is the difference between mass and weight?
Show Answer
Mass is the amount of matter; weight is the force of gravity on that mass
Your mass stays the same on the Moon, but your weight would be less due to weaker gravity.
Question 7
Is dissolving sugar in water a physical or chemical change?
Show Answer
Physical change
The sugar spreads out but is still sugar - you could get it back by evaporating the water.
Question 8
What property of matter describes how much space it takes up?
Show Answer
Volume
Volume is measured in liters, milliliters, or cubic centimeters.
Question 9
What is density?
Show Answer
The amount of mass in a given volume (mass / volume)
Dense objects have particles packed closely together.
Question 10
Name three signs that a chemical change has occurred.
Show Answer
Any three: Color change, gas production (bubbles), temperature change, light production, formation of a precipitate (solid), new smell
