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

  1. Question 1

    Who was the first Canadian woman in space?

    👩‍🚀
    • Roberta Bondar
    • Julie Payette
    • Marc Garneau
    • Chris Hadfield
    Show answer

    Roberta Bondar

    Hint: She is a neurologist who studied how space affects the human body.

  2. Question 2

    What is a space probe?

    🚀
    • a telescope on Earth
    • a spacecraft carrying many tourists
    • an uncrewed spacecraft sent to explore space
    • a kind of rocket fuel
    Show answer

    an uncrewed spacecraft sent to explore space

    Hint: Probes carry cameras and instruments instead of people.

  3. Question 3

    What is the International Space Station?

    🛰️
    • a very large satellite dish on Earth
    • a research laboratory orbiting Earth where astronauts live and work
    • a base on the Moon
    • a telescope on Mars
    Show answer

    a research laboratory orbiting Earth where astronauts live and work

    Hint: Several countries, including Canada, work together on it.

  4. Question 4

    Put these space firsts in order, from the earliest to the most recent.

    • 🌙humans first land on the Moon
    • 🔭the Hubble Space Telescope is launched
    • 🛰️Sputnik 1 is the first satellite launched
    Show answer

    Sputnik 1 is the first satellite launched → humans first land on the Moon → the Hubble Space Telescope is launched

    Hint: Sputnik 1 (1957), then the first Moon landing (1969), then the Hubble Space Telescope (1990).

  5. Question 5

    Why do astronomers use telescopes that detect different kinds of light, such as radio, infrared and visible?

    🌈
    • the telescopes would otherwise be too heavy
    • each kind of light shows different information about an object
    • only visible light is real
    • all kinds show the same thing
    Show answer

    each kind of light shows different information about an object

    Hint: Combining them gives a fuller picture of the universe.

  6. Question 6

    Does it stay near Earth or travel far away? Tap an item, then tap its basket.

    Sort into: 🌍 stays near Earth · 🚀 travels to other worlds

    • 📍GPS satellite
    • 🤖Mars rover
    • 🌙lunar lander
    • 🔭Hubble Space Telescope
    • 🚀Voyager probe
    • 🛰️International Space Station
    Show answer

    🌍 stays near Earth: GPS satellite, Hubble Space Telescope, International Space Station · 🚀 travels to other worlds: Mars rover, lunar lander, Voyager probe

    Hint: Satellites and the space station circle Earth. Probes and rovers are sent to other worlds.
