Yukon Curriculum · from Gradelings · Name: ______________________
Question 1
Which feature do all birds have?
🐦- 🪶feathers
- 🐻fur
- 🐟gills
🪶 feathers
Hint: Every bird has feathers, even birds that can't fly, like penguins.
Question 2
Put the food chain in order. Start where the energy comes from.
- 🦊fox
- 🌿grass
- 🐇rabbit
- ☀️sun
sun → grass → rabbit → fox
Hint: Energy starts with the sun. Plants use sunlight to make food. Then each animal eats the one before it.
Question 3
In a solid, the particles are…
🧊- sliding past each other
- far apart and zooming around
- packed tightly, wiggling in place
packed tightly, wiggling in place
Hint: That's why a solid keeps its shape. Its particles stay in place and just wiggle.
Question 4
How do mittens keep your hands warm in winter?
🧤- they slow down heat leaving your hands
- they make their own heat
- they push the cold away forever
they slow down heat leaving your hands
Hint: Your body makes the heat. Mittens are insulators that keep that heat in.
Question 5
Land with water all around it is called an…
- 🗺️peninsula
- 🏞️valley
- 🏝️island
🏝️ island
Hint: An island is surrounded by water on every side.
Question 6
Wind can pile sand into hills called…
🏜️- glaciers
- deltas
- dunes
dunes
Hint: Sand dunes are made by wind blowing sand into big piles.
Question 7
How do fish breathe underwater?
🐟- with gills
- with their fins
- with their tails
with gills
Hint: Gills take oxygen out of the water. Fins and tails help fish swim and steer.
Question 8
A bear eats berries and salmon. What kind of eater is it?
🐻- herbivore
- carnivore
- omnivore
omnivore
Hint: Berries are plants and salmon are animals. An animal that eats both is an omnivore.
Question 9
Is air matter?
🎈- No, because we can't see it
- No, air is just empty space
- Yes, it is made of particles and takes up space
Yes, it is made of particles and takes up space
Hint: Blow up a balloon. The air inside takes up space, so it is matter!
Question 10
Which is a good insulator that keeps you warm?
- 🍽️a metal tray
- 👕a wet T-shirt
- 🧶a wool sweater
🧶 a wool sweater
Hint: Wool traps air, which slows heat from leaving your body.
