Alberta Curriculum · from Gradelings · Name: ______________________
Question 1
Is it a solid, a liquid or a gas? Tap an item, then tap its basket.
Sort into: 🧊 solid · 💧 liquid · 💨 gas
- 🧊an ice cube
- ♨️steam
- 🌧️rain
- 🎈air in a balloon
- ✏️a pencil
- 🧃juice
Show answer
🧊 solid: an ice cube, a pencil · 💧 liquid: rain, juice · 💨 gas: steam, air in a balloon
Hint: A solid keeps its own shape. A liquid takes the shape of its container. A gas spreads out to fill the space.
Question 2
Many First Nations, Métis and Inuit people have long used natural materials from the land with care. This shows…
🌿- respect for the land
- that only one way exists
- no interest in nature
- a wish to waste
Show answer
respect for the land
Hint: Living in balance with the land is important in many communities.
Question 3
A pot lid has drops on its underside when you boil water. This is like which step?
🍳- precipitation
- evaporation
- condensation
- melting
Show answer
condensation
Hint: Hot vapour cools on the lid and becomes liquid.
Question 4
Two magnets push each other apart without touching. This shows a…
🧲- friction
- contact force
- non-contact force
- twisting force
Show answer
non-contact force
Hint: The magnets act from a distance.
Question 5
An axe splits wood. Its blade is a…
🪓- pulley
- wedge
- wheel
- spring
Show answer
wedge
Hint: A wedge pushes wood apart.
Question 6
A river can change course by…
🏞️- freezing in summer
- wearing away one bank and building up another
- turning into rock
- jumping over the land
Show answer
wearing away one bank and building up another
Hint: Flowing water moves soil and rock.
Question 7
Wind can pile sand into hills called…
🏜️- glaciers
- deltas
- dunes
Show answer
dunes
Hint: Sand dunes are made by wind blowing sand into big piles.
Question 8
Why does soil in a forest often look darker than soil on bare ground?
🌲- forest soil is always wet
- the trees are dark
- fallen leaves rot and add humus
- the forest makes paint
Show answer
fallen leaves rot and add humus
Hint: Humus is dark and rich.
Question 9
A farmer plants shelterbelts of trees around a field. How does it help?
🌲- it slows the wind so soil does not blow away
- it stops the sun
- it hides the field
- it makes the soil harder

Question 10
Many dinosaur fossils are found in Alberta, in places such as…
🏜️- downtown shopping malls
- the top of the Rockies
- Dinosaur Provincial Park
- the middle of lakes
Show answer
Dinosaur Provincial Park
Hint: The park has the badlands where bones are exposed.
