Sample questions
A taste of this unit. In the app, questions change every time and get easier or harder to match your child.
Question 1
Which state of matter takes the shape of its container but keeps the same volume?
- Solid
- Gas
- Liquid
Liquid

Question 2
Which tool measures the mass of an object?
- A graduated cylinder
- A balance
- A thermometer
A balance
Hint: A balance compares masses. A graduated cylinder measures the volume of a liquid.
Question 3
Which is a gas at room temperature?
- Milk
- The helium in a party balloon

The helium in a party balloon
Hint: Helium floats in a balloon because it is a gas.
Question 4

- is alive
- has mass and takes up space
- can be seen
has mass and takes up space
Hint: Even air is matter: it has mass and takes up space, even though you cannot see it.
Question 5
A plastic bottle holds 500 mL of water. The cap is on. If you squeeze the sides, what happens to the volume of the water?
- It doubles
- It drops to about 250 mL
- It stays about 500 mL
It stays about 500 mL
Hint: Liquids are almost impossible to compress.
Question 6
Sand can be poured like a liquid. Why is each grain still a solid?
- Each grain keeps its own shape and volume
- Sand grains are made of liquid
- Sand has no mass
Each grain keeps its own shape and volume
Hint: The pile flows, but each tiny grain is a solid.
