Description de cours

This Grade 9 Science course introduces you to the four main branches of science: Chemistry, Physics, Biology, and Earth and Space Science. You will learn about matter and how it is made up of atomic elements that can be combined to create amazing products. Next, you will investigate energy in the form of electricity and learn how to construct different kinds of circuits. You will learn how the science of astronomy has radically changed our view of ourselves and our place in the universe. You will explore biology by learning about the dynamics of ecosystems and how human activities are affecting their sustainability.

Unit 1: Chemistry: Atoms, Elements, and Compounds

In this unit, you will learn about the atoms, elements, and compounds that make chemicals. Chemistry is important because everything is made of chemicals, even you!  Lesson 1 introduces you to the concept of Matter: what it is and how you can classify it. In the second lesson, you will study atoms, the building blocks of matter, and learn how the modern model of atomic structure developed. Lesson 3 introduces you to the Periodic Table of the Elements, one of the greatest scientific achievements. You’ll learn how to use the table to predict how all kinds of matter will behave. In Lesson 4 you’ll explore how elements combine to form compounds and how this affects their properties. In Lesson 5, you’ll investigate the costs and benefits of using chemical compounds and finish off by developing your own cost-benefit analysis of the development of the Alberta oil sands.

Unit 2: Physics: Characteristics of Electricity

In this unit, you will learn how electricity is made and how it’s used. Everyone uses electrical energy but producing electricity has social, economic, and environmental consequences, so it’s important to use it efficiently, as well as safely. In Lesson 6 you’ll investigate static electricity and examine how it is useful for more than just making your hair stand on end. In Lesson 7, you will be introduced to current electricity and learn why it is so important to modern life. In Lesson 8, you will learn about basic electrical circuits and how they can be used to make current electricity do useful work. Lesson 9 examines the different ways that electricity is produced in Ontario and the costs and benefits of each approach. The unit concludes with an exploration of how and why you should conserve your consumption of electricity.

Unit 3: Earth and Space Science: The Study of the Universe

In this unit, you will learn about the universe and the major scientific theories about its structure and how it began. You will also learn why earth’s unique position in the solar system explains why life was able to evolve here. The unit begins by examining how past civilizations observed the night sky and how they understood it. In Lesson 12, you’ll learn about the life and death of stars, including the sun, and how mysterious objects like Black Holes are made. Lesson 13 introduces you to the solar system, home of the sun and eight planets, including Earth. You’ll examine how the solar system formed and take a tour of the planets. In Lesson, 14 you will look at the history of space exploration, including Canada’s important contributions. In the last lesson of the unit, you will examine the unique features of Planet Earth and why it is able to support life.

Unit 4: Biology: Sustainable Ecosystems

The diversity of life on earth is very special but it is also very threatened. In this unit, you will learn how life sustains itself by cycling energy and materials through ecosystems. The first lesson in the unit introduces you to the dynamic nature of ecosystems and their basic components. In Lesson 17, you’ll focus on the flows of energy and nutrients through ecosystems via food webs. You also learn how sunlight is the source of energy for all life and how plants use the process of photosynthesis to capture it. In Lesson 18, you’ll examine the impact human actions have on terrestrial ecosystems including such famous ecological disasters as the Dust Bowl in the 1930s and the introduction of rabbits into Australia. Lesson 19 continues the theme of threats to sustainability, but this time you focus on aquatic ecosystems. You will investigate the Great Lakes ecosystems and the kinds of threats they are facing from human activities. In the final lesson, you will explore how people can adopt sustainable practices. The emphasis will be on the roles of governments and especially on what you can do as an individual to create an environmentally sustainable society.
