Question 1
What happens to ice when it gets warm?
🧊- 🪨It turns into a rock
- ⬆️It gets bigger
- 💧It melts into water
💧 It melts into water
Hint: Heat makes ice melt. The solid becomes a liquid.
Question 2
Put the water cycle in order. Start with the sun warming the water.
- 🌧️Rain or snow falls
- ☁️Clouds form
- ☀️Sun warms water and it rises
- 🌊Water collects in rivers and oceans
Sun warms water and it rises → Clouds form → Rain or snow falls → Water collects in rivers and oceans
Hint: Warm water rises into the sky, makes clouds, falls as rain, and collects in rivers and oceans.
Question 3
Why must an adult help when we change materials with heat?
🧯- heat is always cold
- adults like to cook alone
- heat and fire can burn us
heat and fire can burn us
Hint: Stay safe! Hot pans, ovens and flames can hurt.
Question 4
Which one makes a mixture of a liquid and a solid?
- Plain water only
- Orange juice with pulp
- An empty cup
Orange juice with pulp
Hint: A mixture has more than one kind of matter.
Question 5
What carries pollen from flower to flower?
- Rocks
- Snow
- Bees
- Clouds
Bees
Hint: They visit many flowers.
Question 6
Which tool helps you share your design idea?
- A nap
- A song
- A snack
- A drawing
A drawing
Hint: Show it on paper.
Question 7
Which animal lives in a wetland?
- Lizard of the dunes
- Mountain goat
- Heron
- Camel
Heron
Hint: Wetlands are marshy.
Question 8

Hint: Very slow erosion.
Question 10
What happens to a puddle of water on a very cold day?
- 🏖️It turns into sand
- 🧃It becomes juice
- 🧊It can freeze into ice
🧊 It can freeze into ice
Hint: Water freezes when it gets cold enough.
