Matter States Classification
Ruben, Mele and Sione are getting a pizza shop ready for a busy evening. Help them classify the matter they use. Use the written clues to answer each question.
Spot the states
Remember: solids keep their own shape; liquids flow and take the shape of their container; gases spread out to fill the space available.
1.Which description best explains what matter is?
- Anything that has mass and takes up space
- Only things that can be seen
- Anything that is hard
- Only solids and liquids
2.The metal pizza tray keeps its own shape when Ruben moves it. Which state of matter is it?
- Solid
- Liquid
- Gas
3.Mele pours tomato sauce from a jug into a bowl. Choose all the properties that describe the sauce.
- It can flow and be poured
- It has a fixed shape of its own
- It takes the shape of its container
- It has a definite volume
4.Classify each shop item as a solid, liquid or gas: dough; water in a glass; air inside an inflated balloon; grated cheese.
- Dough
- Water in a glass
- Air inside an inflated balloon
- Grated cheese
- Liquid
- Solid
- Gas
- Solid
5.Finish the statement: A gas has no definite shape and no definite . It spreads out to fill the available.
6.Sione says, “Air cannot be matter because I cannot see it.” Is his statement true or false?
7.A balloon looks bigger after it is inflated. Explain what this tells you about the air inside it.
8.Mele says a wooden pizza board is a liquid because it is made from tiny particles. Explain why its state is still classified as a solid.
9.The shop has an ice cube, a puddle of melted ice and water vapour in the air above warm water. Name the state of matter for each, in that order.
10.A sealed container holds a fixed amount of liquid sauce. If the sauce is poured into a wider bowl, what changes and what stays the same?
11.Choose one solid, one liquid and one gas from a pizza shop. Explain one property that supports each classification.
