Grade 5 Science practice sheet
New Brunswick Curriculum · from Gradelings · Name: ______________________
Question 1
A warm front is when…
- warm air moves over cooler air
- winds stop
- cold air pushes under warm air
warm air moves over cooler air
Hint: The warm air slides up over the cold air.
Question 2
A hockey puck slides far on ice because…
- there is little friction
- there is a lot of friction
- gravity is off
there is little friction
Hint: Ice is slippery.
Question 3
These ramps all lift a box to the same height. Order them from LEAST force needed to MOST.
- 📐4 m ramp
- 📐2 m ramp
- 📐5 m ramp
- 📐1 m ramp
5 m ramp → 4 m ramp → 2 m ramp → 1 m ramp
Hint: For the same height, a longer ramp is gentler, so it needs less force. The trade-off: you push the box a longer distance.
Question 4
Put the parts of the digestive system in the order food travels through them.
- 🌀Stomach: acid and juices churn the food
- 🩸Small intestine: nutrients pass into the blood
- 💧Large intestine: water is absorbed
- 👄Mouth: teeth chew and saliva mixes in
- ⬇️Esophagus: muscles squeeze food down
Mouth: teeth chew and saliva mixes in → Esophagus: muscles squeeze food down → Stomach: acid and juices churn the food → Small intestine: nutrients pass into the blood → Large intestine: water is absorbed
Hint: Food is chewed in the mouth, squeezed down the esophagus, churned in the stomach, then moves through the small intestine and finally the large intestine.
Question 5
Put the steps of bending your arm in order.
- 🧠The brain sends a signal to the biceps
- 💪The biceps contracts (gets shorter)
- ↪️The arm bends at the elbow joint
- 🦴A tendon pulls on a forearm bone
The brain sends a signal to the biceps → The biceps contracts (gets shorter) → A tendon pulls on a forearm bone → The arm bends at the elbow joint
Hint: Your brain sends the message first. Then the biceps contracts, its tendon pulls the bone, and the arm bends at the elbow joint.
Question 6
Put these in order from LEAST thermal energy to MOST.
- ♨️Water vapour (gas)
- 💧Liquid water
- 🧊Ice (solid water)
Ice (solid water) → Liquid water → Water vapour (gas)
Hint: A solid has the least energy and its particles move the least. A gas has the most.
Question 7
A student crushes a can. This is a…
- chemical change
- change of state
- physical change
physical change
Hint: The shape changed, but it is still the same metal.
Question 8
What gives Earth most of the energy that drives weather?
- the Moon
- the stars
- the Sun
the Sun
Hint: The Sun heats the air, land and water.
Question 9
Why do we put sand on icy sidewalks?
- to add friction so people do not slip
- to melt ice faster than salt
- to make them shine
to add friction so people do not slip
Hint: Sand gives shoes something to grip.
Question 10
Lever, wedge, or wheel and axle? Tap an item, then tap its basket.
Sort into: ⚖️ lever · 🔺 wedge · ⚙️ wheel and axle
- 🔪knife
- 🎡Ferris wheel
- 🔧crowbar
- 🎛️doorknob
- ⚖️seesaw
- 🚪doorstop
⚖️ lever: crowbar, seesaw · 🔺 wedge: knife, doorstop · ⚙️ wheel and axle: Ferris wheel, doorknob
Hint: A lever turns on a fulcrum. A wedge is thin at one edge to split, cut or hold. A wheel and axle is a wheel joined to a rod that turns with it.
Answer key
- 1. warm air moves over cooler air (Weather and the Water Cycle)
- 2. there is little friction (Forces, Friction and Machines)
- 3. 5 m ramp → 4 m ramp → 2 m ramp → 1 m ramp (Simple Machines)
- 4. Mouth: teeth chew and saliva mixes in → Esophagus: muscles squeeze food down → Stomach: acid and juices churn the food → Small intestine: nutrients pass into the blood → Large intestine: water is absorbed (Digestion & Breathing)
- 5. The brain sends a signal to the biceps → The biceps contracts (gets shorter) → A tendon pulls on a forearm bone → The arm bends at the elbow joint (Heart, Bones & Muscles)
- 6. Ice (solid water) → Liquid water → Water vapour (gas) (Changes of State)
- 7. physical change (Physical or Chemical?)
- 8. the Sun (Weather and the Water Cycle)
- 9. to add friction so people do not slip (Forces, Friction and Machines)
- 10. ⚖️ lever: crowbar, seesaw · 🔺 wedge: knife, doorstop · ⚙️ wheel and axle: Ferris wheel, doorknob (Simple Machines)
