  1. Question 1

    Which is a safety rule when there is lightning?

    • Go inside a building or a hard-topped vehicle
    • Swim in the lake
    • Stand under a tall tree
    Show answer

    Go inside a building or a hard-topped vehicle

    Hint: Stay away from open spaces, tall objects and water.

  2. Question 2

    What is the function of the battery in a circuit?

    • To provide the energy that pushes current through the circuit
    • To make light only
    • To control which wire is used
    Show answer

    To provide the energy that pushes current through the circuit

    Hint: It's the energy source.

  3. Question 3

    Which adaptation helps a bird fly?

    • Hollow bones and feathers
    • Gills
    • Thick scales
    Show answer

    Hollow bones and feathers

    Hint: Light bodies and wing feathers help lift.

  4. Question 4

    Why do we always see the same side of the Moon?

    • Earth hides the other side
    • The Moon rotates once in the time it orbits Earth once
    • The Moon does not rotate at all
    Show answer

    The Moon rotates once in the time it orbits Earth once

    Hint: Its rotation and orbit match.

  5. Question 5

    Put these in order, starting with the one closest to the Sun.

    • Mars
    • Uranus
    • Neptune
    • Venus
    • Mercury
    Show answer

    Mercury → Venus → Mars → Uranus → Neptune

    Hint: Try: My Very Educated Mother Just Served Us Nachos (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune). The asteroid belt lies between Mars and Jupiter.

  6. Question 6

    Put these in order from smallest to largest.

    • ✨the universe
    • ☀️the Sun
    • 🪐our solar system
    • 🌌the Milky Way
    • 🌍Earth
    Show answer

    Earth → 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.

  7. Question 7

    The International Space Station is used for…

    • farming fish
    • research in microgravity
    • holding the Olympics
    Show answer

    research in microgravity

    Hint: Scientists do experiments there.

  8. Question 8

    Which group of animals has feathers?

    • Reptiles
    • Amphibians
    • Birds
    Show answer
