LES STRUCTURES SOLIDES ET STABLE
(Strong and Stable Structures)
LES IDÉES PRINCIPAUX (The Big Ideas)
1. A structure has both form and function.
2. Structures are affected by forces acting on them.
3. Structures need to be strong
OVERVIEW:
Both people and animals build structures, and both people and animals need their structures to be strong and stable and to last a long time. Students need to understand the important distinction between strength (the capacity to withstand forces that tend to break an object or change its shape) and stability (the capacity to maintain balance and stay fixed in one position), and the ways in which these two properties affect the usefulness of a structure. Students will investigate the factors that affect a structureís strength and stability, such as its shape and centre of gravity, and apply their learning as they design and build their own strong and stable structures.
Students in Grade 3 will encounter very few hazards in their designing and building activities. However, it is important that they be able to identify general practices that ensure their personal safety and the safety of others and to demonstrate an understanding of the importance of these practices. This includes knowing why work spaces should be kept tidy and uncluttered, and why it is important to follow instructions carefully.
OVERALL EXPECTATIONS:
By the end of Grade 3, students will:

LES FORCES EN ACTION!
(Forces Causing Movement)
OVERVIEW:
There are two basic types of forces that cause movement. Contact forces involve direct interaction (pushes and pulls between surfaces that are in direct contact). Non-contact forces include magnetic and gravitational forces and involve interaction at a distance. In exploring the effects of forces, students will learn about ways in which forces, including forces in nature, cause objects to move. In addition, students will expand their understanding of control by designing and building devices that can use forces to create controlled movement.
Explorations involving forces and movement may require students to manipulate materials. When working with materials in this manner, it is important that students are able to identify practices that ensure their personal safety and the safety of others and to demonstrate an understanding of the importance of these practices. This includes knowing why it is important to protect their eyes and faces from stretched or twisted materials, and their feet from loads that might drop.
Les 6 types de forces sont (The 6 types of forces we are looking at)
LES IDÉES PRINCIPAUX (The Big Ideas)
1. Il existe plusieurs types de forces qui causent le mouvement.
(There are several types of forces that cause movement.)
2. Les forces causent des objets d'accélérer, ralentir ou changer de direction par contact direct ou indirect. (Forces cause objects to speed up, slow down, or change direction through direct contact or through interaction at a distance.)
3. Les forces naturelles (les vents forts, la force de l'eau (l'érosion), peuvent avoir un impact significatif sur les humains etl'environnement, et doivent être considérées avec respect.
(Forces in nature, such as high winds or water, can have a significant impact on humans and the environment, and need to be regarded with respect.)

LES SOLS
(Soils in the Environment)
OVERVIEW:
Soil is not just dirt but an essential source of life and nutrients for many organisms, including humans. Soil provides a base for forests, fields, farms,and gardens and is necessary to many different kinds of animals and plants.Through investigations, students will learn that soils are composed of a variety of living and non-living things and earth materials; that there are different kinds of soil; and that the unique characteristics, composition, and condition of each soil type determine its capacity to sustain life. As they learn about the importance of soils, students will also learn about ways to maintain healthy soil conditions, including the process of composting. When exploring different kinds of soils, students should able to identify practices that ensure their personal safety and the safety of others and to demonstrate an understanding of the importance of these practices. This includes knowing why they should check collected soils for unsafe objects before beginning their investigations, and why they should always wash their hands after completing soil explorations.

OVERALL EXPECTATIONS:
By the end of Grade 3, students will:
- assess the importance of form, function, strength, and stability in structures through time;
- investigate strong and stable structures to determine how their design and materials enable them to perform their load-bearing function;
- demonstrate an understanding of the concepts of structure, strength, and stability and the factors that affect them
