Question 1
What is polar night?
- A very bright night
- A kind of fish
- When the Sun stays below the horizon for a day or more
- A snowstorm
When the Sun stays below the horizon for a day or more
Hint: It happens in winter near the poles.
Question 2
Which is a physical change?
- chopping wood
- baking a cake
- burning wood
chopping wood
Hint: Chopped wood is still wood.
Question 3
A seedling grows taller because its cells…
- turn into water
- divide and get bigger
- disappear
divide and get bigger
Hint: Growth means more cells.
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
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 7
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 8
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 9
Which is a safe habit?
- tasting science materials
- putting equipment away after use
- leaving materials on the floor
putting equipment away after use
Hint: A tidy space is a safe space.
Question 10
In summer, the north end of Earth's axis tilts…
- Toward the Sun
- Away from the Sun
- Nowhere
- Into the Moon
Toward the Sun
Hint: That gives long days in the north.
Answer key
- 1. When the Sun stays below the horizon for a day or more (Midnight Sun and Polar Night)
- 2. chopping wood (Mixtures, Changes and Reactions)
- 3. divide and get bigger (Cells: The Basic Unit of Life)
- 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. there is little friction (Forces, Friction and Machines)
- 7. 5 m ramp → 4 m ramp → 2 m ramp → 1 m ramp (Simple Machines)
- 8. warm air moves over cooler air (Weather and the Water Cycle)
- 9. putting equipment away after use (Measure, Stay Safe and Take Action)
- 10. Toward the Sun (Midnight Sun and Polar Night)
