Grade 4 Science practice sheet
BC Curriculum · from Gradelings · Name: ______________________
Question 1
The school bell rings. Put the steps of your response in order.
- ⚡Nerves carry a message to your brain
- 👂Your ears sense the sound
- 🧠Your brain decides what to do
- 🏃Your muscles move you to line up
Show answer
Your ears sense the sound → Nerves carry a message to your brain → Your brain decides what to do → Your muscles move you to line up
Hint: Your senses notice first. Nerves carry the message to your brain, your brain decides, then your muscles move.
Question 2
What is a biome?
🌍- A kind of rock found in caves
- A weather report for one day
- A large region with a similar climate, plants and animals
- A single tree and the bugs on it
Show answer
A large region with a similar climate, plants and animals
Hint: Biomes are huge areas, like deserts or forests, where the climate and living things are alike.
Question 3
Put the steps of the water cycle in order, starting with the sun.
- 🌧️Rain or snow falls back down
- ☁️Water vapour condenses into clouds
- ☀️The sun heats water in a lake
- ♨️Water evaporates into the air
Show answer
The sun heats water in a lake → Water evaporates into the air → Water vapour condenses into clouds → Rain or snow falls back down
Hint: The sun's heat makes water evaporate. The vapour cools and condenses into clouds, then falls as rain or snow.
Question 4
Anything that has mass and takes up space is called…
🧱- matter
- light
- energy
- sound
Show answer
matter
Hint: Rocks, water and even air are all matter. Light and sound are energy, not matter.
Question 5
How does a hydroelectric dam make electricity? Put the steps in order.
- 🏠Power lines carry it to homes
- ⚡A generator makes electricity
- 🏞️Water is held behind a dam
- 🌊Falling water spins a turbine
Show answer
Water is held behind a dam → Falling water spins a turbine → A generator makes electricity → Power lines carry it to homes
Hint: Stored water falls, spins a turbine, a generator makes electricity, and wires carry it to homes.
Question 6
Put the waxing moon in order, from new moon to full moon.
- 🌓first quarter
- 🌕full moon
- 🌑new moon
- 🌒waxing crescent
- 🌔waxing gibbous
Show answer
new moon → waxing crescent → first quarter → waxing gibbous → full moon
Hint: Waxing means growing: the lit part gets bigger each night, from a thin crescent to a half to more than half (gibbous), then full.
Question 7
Which body part receives messages from your senses and decides what to do?
- 🧠brain
- ❤️heart
- 🍽️stomach
- 🫁lungs
Show answer
🧠 brain
Hint: Your brain is the control centre of your nervous system.
Question 8
Which place is most likely a tropical rainforest?
Rain and snow in one year (cm) - Place C
- Place A
- Place D
- Place B
Show answer
Place A
Hint: A tropical rainforest gets heavy rain almost every day. Look for the tallest bar.
Question 9
Which is an example of evaporation?
- ❄️an icicle growing
- 🚗frost on a car window
- 🧊a lake freezing in winter
- ☀️a puddle drying up after rain
Show answer
☀️ a puddle drying up after rain
Hint: Evaporation turns a liquid into a gas. The puddle's water goes into the air.
Question 10
In which state of matter are the particles packed tightly together?
- 💨gas
- 🧱solid
- 💧liquid
Show answer
🧱 solid
Hint: In a solid, particles are packed tightly and just wiggle in place. That's why solids keep their shape.

- 4. matter (Particles & Mass)
- 5. Water is held behind a dam → Falling water spins a turbine → A generator makes electricity → Power lines carry it to homes (Energy Changes)
- 6. new moon → waxing crescent → first quarter → waxing gibbous → full moon (Earth, Moon & Sun)
- 7. 🧠 brain (Sense & Respond)
- 8. Place A (Biomes)
- 9. ☀️ a puddle drying up after rain (Phase Changes)
- 10. 🧱 solid (Particles & Mass)
