Multiple Choice

Why do we experience day and night?

• The Sun moves around the Earth

• The Earth moves around the Sun

• The Sun has a bright side and a dark side and rotates

• The Earth rotates

Multiple Choice

What is a year?

• The length of time it takes the Earth to orbit the Sun once

• The length of time it takes the Sun to orbit the Earth

• The distance travelled by the Earth as it orbits the Sun

• The time it takes the Sun to rotate once on its orbit.

Things to know about the Earth

• The Earth is a sphere that appears flat to us because it is very large compared to us.

• Day and night are due to the Earth rotating on its axis

• It takes the Earth 24 hours to complete one rotation.

• The side of the Earth facing the Sun receives daylight and the side of the Earth facing away has night.

Multiple Choice

Which is the best description of the Sun?

• The centre of the universe

• A relatively ordinary star

• Ra's chariot

• A ball of fire orbiting the Earth

Things to know about the Sun

• The Sun is also a sphere.

• It is a star like other stars we see in the sky, just a lot closer to us so appearing a lot bigger.

• Radiation from the Sun illuminates and warms the Earth.

• The Sun is many times bigger than the Earth and looks small because it is a long way away from us.

Multiple Choice

What is the Solar system?

• Eight planets, including the Earth, orbiting a star we call the Sun

• Eight planets, including the Sun, orbiting the Earth

• Eight moons orbiting the Sun and the Earth

• Eight planets, including the Earth and the moon, orbiting the Sun

Multiple Choice

• 5

• 6

• 7

• 8

• Mercury, Mars, Venus, Earth

• Mercury, Venus, Earth, Mars

Multiple Choice

• Jupiter, Saturn, Uranus, Neptune

• Jupiter, Saturn, Uranus, Pluto

• Jupiter, Mars, Saturn, Uranus

• Neptune, Jupiter, Venus, Uranus

Multiple Choice

Multiple Choice

What is a galaxy?

• A milk chocolate bar found at the centre of the universe

• Another name for a pan-galactic gargle blaster

• A collection of stars within 1000 light years of each other.

• A collection of gas, dust and billions of stars and their solar systems, held together by gravity.

Multiple Choice

What is the Milky Way?

• A chocolate bar

• Our galaxy, at the centre of the Laniakea supercluster of galaxies

• a river of milk running through the sky

• Our galaxy, on the outskirts of the Laniakea supercluster of galaxies

This shows where our rather ordinary star (the Sun) is in our galaxy (the Milky Way).

The Milky Way is a flat spiral shape containing lots of stars. Because it is a flat disk containing lots of stars and we are near its edge, it appears in the night sky as a bright stripe across the sky.

Multiple Choice

What is a light year?

• The distance light travels in an Earth year

• It's a year you enjoy, compared to a heavy year, which is one you don't enjoy

• The distance from the Earth to the Sun

• The time is takes light to travel from the Sun to the moon and on to Earth

Multiple Choice

What is an astronomical unit (AU)

• The size of the largest milky way bar ever made

• 1000 light years

• Roughly the distance from the Earth to the Sun

• The distance from the Sun to the centre of the galaxy

A light-year

For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year. One light-year is about 9 trillion km. That is a 9 with 12 zeros behind it.

Multiple Choice
