Understanding the Structure of the Ontario Grade 3 Science Curriculum

The Ontario Grade 3 Science curriculum is organized around three key strands: Science and Technology, Living Things and Their Environments, and Structures and Mechanisms. Each strand builds upon prior knowledge and progressively develops students' understanding of scientific concepts and processes. The curriculum emphasizes inquiry-based learning, encouraging students to ask questions, investigate, and draw conclusions based on evidence.

1. Science and Technology: Investigating the World Around Us

This strand focuses on developing students’ understanding of the scientific method and the role of technology in solving problems. Students learn to:

• Ask questions and develop hypotheses: This involves formulating testable predictions based on observations. For example, students might hypothesize about the effect of different liquids on plant growth.
• Plan and conduct investigations: This includes designing fair tests, collecting data, and using appropriate tools and techniques. A simple investigation might involve comparing the dissolving rates of different substances in water.
• Analyze data and draw conclusions: Students learn to interpret their findings, identify patterns, and draw evidence-based conclusions. They might create charts and graphs to display their data and explain their observations.
• Communicate findings: This involves sharing their results through oral presentations, written reports, or visual displays. Students learn to clearly and accurately communicate their scientific findings to others.
• Understand the role of technology: Students explore how technology is used to solve problems and improve our lives. This could involve investigating simple machines or exploring different technologies used in everyday life.

Examples of Grade 3 Activities:

• Designing a Rube Goldberg machine: Students work collaboratively to design and build a machine that performs a simple task using a series of interconnected elements. This activity integrates creativity, problem-solving, and an understanding of simple machines.
• Investigating the properties of different materials: Students explore the properties of materials such as wood, plastic, and metal by testing their flexibility, strength, and water resistance. This activity helps students develop observational skills and an understanding of material properties.
• Building and testing simple circuits: Students learn about basic electrical circuits by building simple circuits with batteries, bulbs, and wires. This introduces them to fundamental concepts in electricity and technology.

2. Living Things and Their Environments: Exploring the Natural World

This strand focuses on the characteristics and life cycles of living things, as well as their interactions with their environment. Students learn to:

• Identify and classify living things: Students learn to distinguish between plants and animals and classify them based on their characteristics. They might create a classification system based on observable traits.
• Understand basic needs of living things: Students learn about the basic needs of plants and animals, including air, water, food, and shelter. They might conduct experiments to investigate how different factors affect plant growth.
• Explore life cycles: Students learn about the life cycles of common plants and animals, such as the butterfly or the bean plant. They might observe these life cycles firsthand through germination experiments or butterfly observation.
• Understand habitats and ecosystems: Students learn about different habitats and how living things interact with their environment. They might create a model ecosystem or investigate the interdependence of organisms within a specific habitat.
• Explore the impact of humans on the environment: Students begin to understand how human actions can affect the environment, such as pollution or habitat destruction. This introduces important concepts related to environmental stewardship.

Examples of Grade 3 Activities:

• Creating a terrarium or aquarium: Students design and build a mini-ecosystem to observe the interactions between living things. This allows them to observe the needs of plants and animals in a contained environment.
• Investigating food chains and food webs: Students learn about the flow of energy in an ecosystem by creating food chains and food webs. This activity helps them understand the interdependence of organisms.
• Observing plant growth: Students plant seeds and observe the growth of plants over time, documenting their observations and drawing conclusions about the factors that affect plant growth.
• Studying animal adaptations: Students research and present on how different animals are adapted to their environments. This encourages research skills and an understanding of evolutionary processes.

3. Structures and Mechanisms: Building and Understanding Systems

This strand focuses on the design and function of structures and mechanisms. Students learn to:

• Identify and describe different types of structures: Students learn about various structures, including bridges, buildings, and machines, and how they are designed to serve a specific purpose.
• Understand the properties of materials: Students investigate the properties of different materials and how these properties influence the design and function of structures.
• Explore simple machines: Students learn about simple machines such as levers, pulleys, and inclined planes, and how they make work easier.
• Design and build simple structures: Students design and construct simple structures, such as bridges or towers, using various materials. This integrates engineering principles and problem-solving skills.
• Understand forces and motion: Students begin to explore basic concepts related to forces, such as gravity and friction, and how these forces affect motion.

Examples of Grade 3 Activities:

• Building a bridge out of straws and tape: Students work in teams to design and build a bridge that can support a certain weight. This activity combines engineering design principles with an understanding of structural strength.
• Investigating the function of levers and pulleys: Students use simple machines to lift objects and explore how these machines make work easier. This helps them understand the principles of mechanical advantage.
• Designing and building a marble run: Students design and construct a marble run using various materials and mechanisms. This activity encourages creativity, problem-solving, and an understanding of simple machines.
• Exploring forces and motion with ramps and toy cars: Students experiment with ramps and toy cars to observe the effects of gravity and friction on motion. This introduces fundamental concepts in physics.

Assessment and Evaluation in Grade 3 Science

Assessment in the Ontario Grade 3 Science curriculum is ongoing and focuses on student learning and growth. Teachers use a variety of methods, including:

• Observations: Teachers observe students during hands-on activities and discussions to assess their understanding of concepts and their ability to apply scientific processes.
• Performance tasks: Students complete tasks such as building models, conducting experiments, and presenting findings to demonstrate their understanding.
• Written work: Students complete worksheets, lab reports, and other written assignments to demonstrate their knowledge and skills.
• Oral communication: Students participate in discussions and presentations to share their understanding and communicate their findings.

The focus is on providing feedback to students to support their learning and progress. This formative assessment helps teachers adjust their instruction to meet the needs of individual students.
