Study Notes: Ontario Grade 3 Science - Structures Unit
-
States of Matter: Matter exists in three states: solid, liquid, and gas.
- Solids have a definite shape and volume. Examples include rocks, wood, and ice.
- Liquids have a definite volume but take the shape of their container. Examples include water, juice, and milk.
- Gases have no definite shape or volume and fill their container completely. Examples include air, steam, and oxygen.
-
Changes of State: Matter can change from one state to another.
- Melting: Changing from a solid to a liquid (e.g., ice melting into water).
- Freezing: Changing from a liquid to a solid (e.g., water freezing into ice).
- Boiling: Changing from a liquid to a gas (e.g., water boiling into steam or water vapor).
- Condensation: Changing from a gas to a liquid (e.g., water vapor turning into rain or dew).
-
Properties of Matter: Matter has different properties that help us describe it. Examples include color, shape, size, texture, hardness, and flexibility.
- Mass: The amount of matter in an object.
- Volume: The amount of space an object takes up.
-
Mixtures and Solutions: Mixtures are combinations of two or more substances that are not chemically combined.
- Mixtures can be separated by physical methods like sorting.
- Solutions are special mixtures where one substance dissolves completely into another. Examples include salt dissolving in water or sugar dissolving in water.
-
Physical Changes: A physical change alters the form of a substance but does not change its chemical composition.
- Examples include tearing a piece of paper, bending a wire, melting ice, and dissolving sugar.
- These changes do not create a new substance.
-
Separating Mixtures: Physical methods can be used to separate different substances in a mixture, such as using a sieve, magnet, or evaporation.
- Filtration separates solids from liquids.
- Evaporation separates a solid dissolved in a liquid by heating the solution to allow the liquid to boil and be removed.
-
Important Concepts:
- Matter is anything that takes up space and has mass.
- Materials are different kinds of matter, and their properties make them suitable for certain uses.
- Changes in temperature directly affect the state of matter.
- Understanding the different states of matter is crucial for many sciences and everyday activities.
-
Activity Examples:
- Observing different materials changing states or being mixed.
- Identifying the materials in a mixture.
- Experimenting with heating or cooling substances to see how states change.
- Separating mixtures.
Additional Notes
- Emphasize hands-on activities and observations as critical for learning and understanding these concepts.
- Make connections to real-world examples and encourage students' curiosity about the properties of matter.
- Encourage the use of vocabulary related to these concepts, including terms like solid, liquid, gas, mixture, solution, physical change, and properties.
- Using visuals like diagrams, charts, and demonstrations helps to illustrate the concepts effectively.
