🔬 Grade 3 Science

Units

1. Unit 1

   🥽Science Skills & Safety

   Making predictions and observations, running a fair test that changes one thing, using simple tools safely, the engineering design steps, debugging a simple program, and how science helps solve real problems.

   Approved guide: NWT Science and Technology K–6 (2004), Physical science · measuring, doing investigations and using materials safely

2. Unit 2

   🧲Pushes, Pulls & Forces

   Forces as pushes and pulls, contact and non-contact forces (gravity, magnetism, static electricity), friction, how bigger forces change motion more, and helmets and seat belts as safety devices.

   Approved guide: NWT Science and Technology K–6 (2004), Physical science · contact and non-contact forces, and how pushes, pulls and twists change motion

3. Unit 3

   🏎️Speed & Motion

   Practises speed as the distance an object travels in a certain time, inertia (objects keep doing what they are doing until a force acts), and how mass and force affect how quickly motion changes.

   Approved guide: NWT Science and Technology K–6 (2004), Physical science · speed, inertia, and how mass and force affect how quickly motion changes

4. Unit 4

   🏗️Structures & Their Jobs

   What makes something a structure, how its shape fits its job (a bowl-shaped nest, a sloped roof), structures built by animals and by people, and how they change the environment.

   Approved guide: NWT Science and Technology K–6 (2004), Physical science · what structures are for, and how materials are joined

5. Unit 5

   🌉Strong & Stable

   Strength as holding a load and stability as staying balanced, how shape, a wide base and materials help, and how struts (pushed) and ties (pulled) work in a frame.

   Approved guide: NWT Science and Technology K–6 (2004), Physical science · strong and stable structures, shapes in nature and building

6. Unit 6

   🦋Basic Needs & Life Cycles

   Practises the basic needs of organisms (food, water, air, shelter) and the life cycles of plants and animals, including metamorphosis in butterflies and frogs.

   Approved guide: NWT Science and Technology K–6 (2004), Life science · the basic needs of organisms and the life cycles of plants and animals

7. Unit 7

   🐞Grouping Living Things

   Biodiversity (the variety of life in a place) and sorting living things into groups by their features: backbones, legs, fur, feathers, fins and more.

   Approved guide: NWT Science and Technology K–6 (2004), Life science · classification systems that group living things by what they have in common

8. Unit 8

   🔬How Scientists Find Out

   Practises how science builds explanations: observing and measuring, collecting data, making a hypothesis and checking whether the evidence supports it, and how the knowledge is used in engineering and technology.

   Approved guide: NWT Science and Technology K–6 (2004), Physical science · scientific explanations, data, hypotheses and how evidence supports predictions

9. Unit 9

   💡Solutions, Technology & Taking Action

   Practises that problems can have many solutions, weighing benefits and drawbacks of technology, and taking action on local issues such as litter, safer structures and habitats.

   Approved guide: NWT Science and Technology K–6 (2004), Physical science · many possible solutions, effects of technology and taking action on science and environment issues

10. Unit 10

    🌟Science All Around Me

    Practises connecting science ideas to careers, hobbies and activities, and the scientific attitudes of curiosity and belonging: everyone can contribute to science.

    Approved guide: NWT Science and Technology K–6 (2004), Physical science · belonging and curiosity in science, and links between science and careers, hobbies and activities
