Grade 9 Science enables students to develop their understanding of basic concepts in biology, chemistry, earth and space science, and physics, and to relate science to technology, society, and the environment. Throughout the course, students will develop their skills in the processes of scientific investigation. In Grade 9 Science, students will acquire an understanding of scientific theories and conduct investigations related to sustainable ecosystems; atomic and molecular structures and the properties of elements and compounds; the study of the universe and its properties and components; and the principles of electricity.

UNIT ONE

Chemistry

Essential Question: How can understanding the physical and chemical properties of elements and compounds help us explore science, technology and the environment?

  • In this unit, students will learn to define and use various terminology as it relates to the classification of matter. Students will also be introduced to the Periodic Table of Elements and will learn to arrange electronic distribution using the Bohr-Rutherford model for the first 20 elements. Students will extend their understanding and relate atomic structure to the position of an element in the periodic table and compare/contrast the physical properties of different elements within a group family.

UNIT TWO

Electricity

Essential Question: How can electrical energy be transformed into useful forms of energy? What impact does the generation and use of electricity have on our world?

  • In this unit, students will discuss the basic properties and principles of static and current electricity and predict different materials’ pull/hold on electric charges. Students will explore the transfer of static charge between materials by friction, contact and/or induction. Students will examine how different devices use/control static electricity and improve electrical efficiency and compare and contrast the basics of static and current electricity. Students will extend their understanding and know how to calculate the energy consumption and efficiency of different appliances.

UNIT THREE

Sustainable Ecosystems

Essential Question: What does it mean to live sustainably? How can we reduce our ecological footprint?

  • In this unit, students will compare and contrast living/non-living features of land and water-based ecosystems, describe and compare nutrient cycling between the four different spheres and discuss the maintenance and sustainability of the four spheres and human interactions. Students will also investigate and discuss human activities and the impact they have on different ecosystems, including pollution, invasive species, acid rain/acidic water systems and clean-ups.

UNIT FOUR

Earth & Space

Essential Question: What makes up our solar system and how do each of the components interact with one another? How does the relationship between the Sun and the Earth impact life on Earth?

  • In this unit, students will investigate the characteristics and properties of a variety of celestial objects visible from Earth in the night sky. Students will discuss the Sun’s composition and energy source, as well as the motions of the Sun, Moon and Earth. Students will also learn about the stars.
