Question 1
Which group of animals has feathers?
- Reptiles
- Amphibians
- Birds
Show answer
Birds
Hint: All birds have feathers, and most can fly.
Question 2
A tick feeds on a dog's blood and harms it. This relationship is called…
- parasitism
- mutualism
- pollination
Show answer
parasitism
Hint: One organism benefits and the other is harmed.
Question 3
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.
Question 4
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.
Question 5
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.
Question 6
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.
Question 7
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.
Question 8
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.
Question 9
Put the steps of making hydroelectricity at a dam in order.
- 🌀The moving water spins a turbine
- 🌊Water rushes through a pipe in the dam
- ⚡A generator makes electricity
- 🏞️A dam holds back water in a reservoir
- 🏠Power lines carry it to homes and farms
Show answer
A dam holds back water in a reservoir → Water rushes through a pipe in the dam → The moving water spins a turbine → A generator makes electricity → Power lines carry it to homes and farms
Hint: A dam stores water. The water flows through a turbine, the turbine spins a generator, and wires carry the electricity to homes.
Question 10
Ferns and mosses reproduce using…
- flowers and fruit
- spores
- seeds in cones
Show answer
spores
Hint: Spores are tiny cells that grow into new plants.
