California Content Standards · from Gradelings · Name: ______________________
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
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 3
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 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
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 7
Which tool helps you share your design idea?
- A song
- A drawing
- A nap
- A snack
A drawing
Hint: Show it on paper.
Question 8
Which animal could live on a snowy mountain?
- Mountain goat
- Crab
- Jellyfish
- Parrot
Mountain goat
Hint: Good climbers in the cold.
Question 9
A frozen river of ice that moves slowly is a…
- valley
- plain
- glacier
- pond
glacier
Hint: Found on high mountains.
Question 10
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.
