Newfoundland and Labrador Curriculum · from Gradelings · Name: ______________________
Question 1
Put these in order, starting with the one closest to the Sun.
- Mars
- Uranus
- Neptune
- Venus
- Mercury
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.
Question 2
Put these in order from smallest to largest.
- ✨the universe
- ☀️the Sun
- 🪐our solar system
- 🌌the Milky Way
- 🌍Earth
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.
Question 3
Which group of animals has feathers?
- Reptiles
- Amphibians
- Birds
Birds
Hint: All birds have feathers, and most can fly.
Question 4
A tick feeds on a dog's blood and harms it. This relationship is called…
- parasitism
- mutualism
- pollination
parasitism
Hint: One organism benefits and the other is harmed.
Question 5
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
Go inside a building or a hard-topped vehicle
Hint: Stay away from open spaces, tall objects and water.
Question 6
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
To provide the energy that pushes current through the circuit
Hint: It's the energy source.
Question 7
Which adaptation helps a bird fly?
- Hollow bones and feathers
- Gills
- Thick scales
Hollow bones and feathers
Hint: Light bodies and wing feathers help lift.
Question 8
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
The Moon rotates once in the time it orbits Earth once
Hint: Its rotation and orbit match.
Question 9
The International Space Station is used for…
