Sample questions

A taste of this unit. In the app, questions change every time and get easier or harder to match your child.

  1. Question 1

    How did many communities use the sky as a calendar?

    Reading the Night Sky

    For thousands of years, Indigenous peoples across North America have watched the night sky closely. Knowledge about the stars, the Moon and the seasons has been passed down through generations in stories, songs and teachings shared by Elders and Knowledge Keepers.

    Different Nations have their own names and stories for the same groups of stars. A star pattern that some people call the Big Dipper may be seen as a different figure in another Nation's teachings.

    Many communities have used the sky as a calendar. The changing shape of the Moon and the rising of certain stars could signal when it was time to fish, hunt, gather plants or move to a new camp. Some Indigenous calendars name each Moon cycle after what is happening in nature at that time of year.

    Today, some scientists and Indigenous Knowledge Keepers work together, sharing different ways of knowing about the sky.

    • The Moon was used to measure temperature
    • The stars showed the exact date of each birthday
    • The sky was used to predict earthquakes
    • The Moon's shape and certain stars signalled times to fish, hunt or gather
    Show answer

    The Moon's shape and certain stars signalled times to fish, hunt or gather

    Hint: Look at the third paragraph.

  2. Question 2

    Many Indigenous peoples have watched the Moon and stars closely. One way this knowledge was used is to…

    🌙
    • measure the distance to other galaxies
    • predict earthquakes
    • find metals underground
    • track the seasons and know when to fish, hunt or harvest
    Show answer

    track the seasons and know when to fish, hunt or harvest

    Hint: The sky changes in a regular pattern through the year, so it works like a calendar.

  3. Question 3

    Is it in our solar system or beyond it? Tap an item, then tap its basket.

    Sort into: ☀️ in our solar system · 🌌 beyond our solar system

    • 🌌the centre of the Milky Way
    • ☄️Halley's Comet
    • 🧊Jupiter's moon Europa
    • 🪨the asteroid belt
    • ✨the North Star (Polaris)
    • 🌀the Andromeda Galaxy
    Show answer

    ☀️ in our solar system: Halley's Comet, Jupiter's moon Europa, the asteroid belt · 🌌 beyond our solar system: the centre of the Milky Way, the North Star (Polaris), the Andromeda Galaxy

    Hint: Our solar system is the Sun and everything that orbits it. Other stars, nebulas and galaxies are far beyond it.

  4. Question 4

    Put these in order from smallest to largest.

    • 🪐our solar system
    • ☀️the Sun
    • 🌙the Moon
    • 🌌the Milky Way
    • ✨the universe
    Show answer

    the Moon → the Sun → our solar system → the Milky Way → the universe

    Hint: The Moon orbits Earth. Earth orbits the Sun. The Sun and its planets make our solar system, which is one tiny part of the Milky Way. The universe holds billions of galaxies.

  5. Question 5

    What is the name of our galaxy?

    🌌
    • Andromeda
    • the Milky Way
    • the Big Dipper
    • the solar system
    Show answer

    the Milky Way

    Hint: On a very dark night, it looks like a hazy, milky band of light.

  6. Question 6

    What is a light-year?

    • a year on another planet
    • the time Earth takes to orbit the Sun
    • the distance light travels in one year
    • how long a star shines
    Show answer

    the distance light travels in one year

    Hint: Even though it has “year” in its name, a light-year measures distance. It's about 9.5 trillion km.
