Biomes
Deserts, tundra and rainforests
What your child practises
Earth's major biomes (tundra, boreal forest, grassland, desert, rainforest and more), reading clue tables and rainfall graphs, and how living things are adapted to each biome.
Yukon Curriculum learning standard: Biomes as large regions with similar environmental features
Sample questions
A taste of this unit. In the app, questions change every time and get easier or harder to match your child.
Question 1
Thick white fur helps an Arctic fox survive in the…
🦊- ❄️tundra
- 🌵desert
- 🌾grassland
- 🌴tropical rainforest
❄️ tundra
Hint: Thick fur keeps it warm, and white fur blends in with the snow.
Question 2
A cactus stores water in its thick stem. Which biome is it adapted to?
🌵- ❄️tundra
- 🌊ocean
- 🏜️desert
- 🌴tropical rainforest
🏜️ desert
Hint: Storing water helps a cactus survive in a place with very little rain.
Question 3
What is a biome?
🌍- A weather report for one day
- A single tree and the bugs on it
- A large region with a similar climate, plants and animals
- A kind of rock found in caves
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 4
Many grassland animals, like prairie dogs, live in burrows. How does this help them?
🌾- Burrows help them catch fish
- Burrows help them climb trees
- Burrows protect them from heat, cold and predators
- Burrows keep them wet all day
Burrows protect them from heat, cold and predators
Hint: Grasslands have few trees to hide in, so going underground is a good way to stay safe.
Question 5
Which biome is each living thing adapted to? Tap an item, then tap its basket.
Sort into: 🌵 desert · ❄️ tundra · 🌴 tropical rainforest
- 🦌caribou
- 🦎lizard
- 🐪camel
- 🐒monkey
- 🦜parrot
- 🦉snowy owl
🌵 desert: lizard, camel · ❄️ tundra: caribou, snowy owl · 🌴 tropical rainforest: monkey, parrot
Hint: Deserts are dry, the tundra is cold with no trees, and tropical rainforests are hot and wet.
Question 6
Which place is most likely a desert?
Rain and snow in one year (cm) - Place D
- Place C
- Place A
- Place B
Place D
Hint: A desert gets less than 25 cm of rain and snow in a whole year. Look for the shortest bar.
