These are the science topics we will be learning this year.
UNDERSTANDING LIFE SYSTEMS: HABITATS AND COMMUNITIES
Fundamental Concepts
|
Big Ideas
|
Systems and Interactions
Sustainability and Stewardship
|
Plants and animals are interdependent and are
adapted to meet their needs from the resources available in their particular
habitats. (Overall expectations 1, 2, and 3)
Changes to habitats (whether caused by natural or
human means) can affect plants and animals and the relationships between
them. (Overall expectations 2 and 3) Society relies on plants and animals.
(Overall expectations 1 and 2)
|
OVERALL EXPECTATIONS By the end of Grade 4, students
will:
1. analyse the effects of human activities on
habitats and communities;
2. investigate the interdependence of plants and
animals within specific habitats and communities;
3. demonstrate an understanding of habitats and
communities and the relationships among the plants and animals that live in
them.

UNDERSTANDING STRUCTURES AND MECHANISMS: PULLEYS AND
GEARS
Fundamental Concepts
|
Big Ideas
|
Systems and Interactions
Energy
|
Pulleys and gears change the speed, direction, and
motion of, and force exerted on, moving objects. (Overall expectations 2 and
3)
Pulleys and gears make it possible for a small input
force to generate a large output force. (Note: Grade 4 students need to
understand mechanical advantage only in its qualitative sense). (Overall
expectation 1)
Gears are specialized wheels and axles that are used
daily in many machines. (Overall expectations 1, 2, and 3)
|
OVERALL EXPECTATIONS By the end of Grade 4, students
will:
1. evaluate the impact of pulleys and gears on
society and the environment;
2. investigate ways in which pulleys and gears
modify the speed and direction of, and the force exerted on, moving objects;
3. demonstrate an understanding of the basic
principles and functions of pulley systems and gear systems.

| UNDERSTANDING MATTER AND ENERGY: LIGHT AND SOUND
Fundamental Concepts
|
Big Ideas
|
Energy
|
Light and sound are forms of energy with specific
properties. (Overall expectations 2 and 3)
Sound is created by vibrations. (Overall
expectations 2 and 3)
Light is required to see. (Overall expectation 3)
Technological innovations involving light and sound have an impact on the
environment. (Overall expectation 1)
|
OVERALL EXPECTATIONS By the end of Grade 4, students
will:
1. assess the impact on society and the environment
of technological innovations related to light and sound;
2. investigate the characteristics and properties of
light and sound;
3. demonstrate an understanding of light and sound
as forms of energy that have specific characteristics and properties.
|
UNDERSTANDING EARTH AND SPACE SYSTEMS: ROCKS AND
MINERALS
Fundamental Concepts
|
Big Ideas
|
Change and Continuity
Sustainability and
Stewardship Structure and Function
|
Rocks and minerals have unique characteristics and
properties that are a result of how they were formed. (Overall expectations 2
and 3) The properties of rocks and minerals determine society’s possible uses
for them. (Overall expectations 1 and 2)
Our use of rocks and minerals affects the environment.
(Overall expectation 1)
|
OVERALL EXPECTATIONS By the end of Grade 4, students
will:
1. assess the social and environmental impacts of
human uses of rocks and minerals;
2. investigate, test, and compare the physical
properties of rocks and minerals;
3. demonstrate an understanding of the physical
properties of rocks and minerals
