Grade 9 Science at Ancaster HS

What is in Grade 9 Science?Both the applied and academic programs cover the same overall units of study

There are five areas of study or skill development

Units We Look At1. Scientific Skill Development2. Sustainable Ecosystems3. Atoms, Elements and

Compounds4. The Study of the Universe5. The Characteristics of

Electricity

How is Applied Different From Academic?The method of teaching the material

and the application of the topics is different

Our Applied courses focus on hands on application of theory

You get to try labs many times to help you understand a theory

Academic courses focus more on the theory’s impact in society or the environment

What are the States of Matter?3 Forms:

Solid, Liquid, Gas

What are Changes in Matter?

6 Changes:

- Evaporation - Liquid --> Gas- Condensation - Gas --> Liquid - Melting (Liquification) - Solid --> Liquid- Freezing (Solidification) - Liquid --> Solid- Sublimation – Solid --> Gas- Deposition - Gas --> Solid

But, What is Matter?Made up of atoms and moleculesHas mass

What makes a state of matter?The physical state in which the molecules

and atoms of a substance are found

Changing States of MatterMolecules and atoms can move from one

physical state to another and not changeWater, H2O, has the same properties as a liquid

as it does as a solid (ice) or a gas (steam – water vapour)

Although its physical state may change, its chemical state remains the same
