Question 1
A rubber ball is…
- 💨a gas
- 💧a liquid
- ⚽a solid
⚽ a solid
Hint: A ball keeps its shape, so it is a solid.
Question 2
You squeeze a ball of clay into a snake shape. Is it still clay?
🐍- yes, only the shape changed
- no, it became metal
- no, it became water
yes, only the shape changed
Hint: Squeezing and rolling change the shape, not the material.
Question 3
Put the water cycle in order. Start with the sun warming the water.
- 🌊Water collects in rivers and oceans
- 🌧️Rain or snow falls
- ☁️Clouds form
- ☀️Sun warms water and it rises
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 4
A fruit salad has apples, grapes and melon. It is a…
🍉- solid block
- mixture
- gas
mixture
Hint: A mixture is made of different things put together.
Question 5
Burrs stick to a dog's fur. This helps the plant…
- get sunlight
- spread its seeds
- drink water
- make flowers
spread its seeds
Hint: Seeds ride to a new place.
Question 6
Which plant grows in a desert?
- Cactus
- Seaweed
- Moss on a log
- Water lily
Cactus
Hint: It stores water.
Question 7
Water as a solid is…
- rain
- ice
- steam
- a river
ice
Hint: Frozen water.
Question 8
Lava from a volcano cools into new rock in days. This is…
- millions of years
- no change
- slow
- fast
fast
Hint: Days is a short time for Earth.
Question 9
What happens to water in the freezer?
❄️- 💨It disappears
- 🧃It turns into juice
- 🧊It freezes into ice
🧊 It freezes into ice
Hint: Cold makes water freeze. The liquid becomes a solid.
Question 10
A chocolate bar melts in a warm car, then cools at home. Is it still chocolate?
🍫- no, it is now bread
- yes, it is still chocolate
- no, it is now plastic
yes, it is still chocolate
Hint: Melting and cooling are physical changes. The chocolate is the same stuff.

- 6. Cactus (Habitats Near & Far)
- 7. ice (Land & Water Maps)
- 8. fast (Fast & Slow Earth Changes)
- 9. 🧊 It freezes into ice (Solids & Liquids)
- 10. yes, it is still chocolate (Changing Materials)
