    Ages 12 to 13Concept
  • Science // Waves, Light & Sound

    Waves & Different Materials

    Explain how waves can be absorbed, transmitted, or reflected by different materials, and apply these interactions to explain colour perception, sight…

    Ages 12 to 13Concept
  • Science // Weather & Climate

    Types of Weather

    Identify and describe different types of weather — sunny, rainy, windy, snowy, cloudy, foggy, stormy — and describe what the weather is like today using simple…

    Ages 5 to 7Concept
  • Science // Weather & Climate

    Seasons & Weather Patterns

    Know that weather changes with the seasons — spring brings rain and new growth, summer is warmest with long days, autumn brings cooling and falling leaves…

    Ages 5 to 7Concept
  • Science // Weather & Climate

    Rain & Puddles

    Know that rain falls from clouds in the sky, that puddles disappear because water goes back into the air, and that this is part of how water moves around — up…

    Ages 5 to 7Concept
  • Science // Weather & Climate

    Temperature & Thermometers

    Understand temperature as how hot or cold something is, that a thermometer measures temperature, and use words like hot, warm, cool, and cold to describe how…

    Ages 5 to 7Concept
  • Science // Weather & Climate

    What Is Wind?

    Know that wind is moving air, that it can be gentle (a breeze) or very strong (a gale), and that wind can move things like leaves, kites, flags, and even push…

    Ages 5 to 7Concept
  • Science // Weather & Climate

    Weather Forecasting & Safety

    Ask questions to obtain information about the purpose of weather forecasting and how people prepare for and respond to severe weather

    Ages 5 to 6Concept
  • Science // Weather & Climate

    Storm Safety

    Know basic storm safety: during thunder and lightning, go indoors or into a car, stay away from trees and water; understand that storms can be frightening but…

    Ages 5 to 7Concept
  • Science // Weather & Climate

    Geography & Local Weather

    Know that different places around the world have very different typical weather — tropical places are hot and wet all year, deserts are very dry, polar regions…

    Ages 7 to 9Concept
  • Science // Weather & Climate

    The Water Cycle

    Understand the water cycle: the Sun heats water in oceans and lakes causing it to evaporate into water vapour, the vapour rises and cools to form clouds…

    Ages 7 to 9Concept
  • Science // Weather & Climate

    Weather vs Climate

    Distinguish between weather and climate: weather is what the atmosphere is doing right now or today (it can change hour to hour), while climate is the typical…

    Ages 7 to 9Concept
  • Science // Weather & Climate

    Cloud Types

    Identify the three main cloud types — cumulus (fluffy, fair weather), stratus (flat layers, overcast or drizzle), and cirrus (thin wisps, high up) — and…

    Ages 7 to 9Concept
  • Science // Weather & Climate

    What Causes Wind

    Understand what causes wind: the Sun heats the Earth's surface unevenly, warm air rises because it is lighter, and cooler air rushes in to take its place — this…

    Ages 7 to 9Concept
  • Science // Weather & Climate

    Weather Forecasting

    Know that meteorologists are scientists who study and forecast the weather using satellites, radar, weather balloons, and computer models, and that weather…

    Ages 7 to 9Concept
  • Science // Weather & Climate

    Thunder & Lightning

    Know that thunder and lightning happen during thunderstorms: lightning is a giant spark of electricity that forms in clouds, thunder is the sound the lightning…

    Ages 7 to 9Concept
  • Science // Weather & Climate

    Climate Change Basics

    Understand the basics of climate change: Earth’s atmosphere traps some of the Sun's heat (the greenhouse effect), burning fossil fuels adds extra greenhouse…

    Ages 9 to 11Concept
  • Science // Weather & Climate

    Natural resources

    Obtain and combine information to describe that energy and fuels are derived from natural resources and that their uses affect the environment
