Arizona Academic Standards · from Gradelings · Name: ______________________
Question 1
Why would someone cut wood into boards?
- 🌳to make the wood alive again
- 💧to turn the wood into water
- 🪵to build things like a shelf or a birdhouse
🪵 to build things like a shelf or a birdhouse
Hint: We change the shape of materials so we can use them in new ways.
Question 2
Which change can be undone?
- 🧊melting ice
- 🍪baking cookies
- 🔥burning wood
🧊 melting ice
Hint: Melted ice can be frozen again. You can't un-bake a cookie!
Question 3
Put the water cycle in order. Start with the sun warming the water.
- 🌧️Rain or snow falls
- ☀️Sun warms water and it rises
- ☁️Clouds form
- 🌊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 4
Which material repels water?
- 🛍️a plastic bag
- 🧻a paper towel
- 🧽a sponge
🛍️ a plastic bag
Hint: Repel means water runs off instead of soaking in.
Question 5
What can a big storm wave do quickly?
- Make a canyon
- Wash away part of a beach
- Grow a mountain
- Freeze the ocean
Wash away part of a beach
Hint: Strong waves move sand.
Question 6
A plant on a sunny windowsill bends toward…
- the light
- the floor
- the dark
- the door
the light
Hint: Plants grow toward light.
Question 7
Which material is best for a roof in a hailstorm?
- Paper
- Cloth
- Strong metal
- Thin plastic wrap
Strong metal
Hint: Hail is hard ice.
Question 8
Which one changes a material by warming it?
- ❄️freezing water
- 🧈melting butter in a pan
- 🧺folding a towel
🧈 melting butter in a pan
Hint: Warming means making something hotter. Butter melts when it gets warm.
Question 9
A rubber ball is…
- 💨a gas
- ⚽a solid
- 💧a liquid
⚽ a solid
Hint: A ball keeps its shape, so it is a solid.
Question 10
A glacier is a big piece of…
- 🌋hot lava
- 🧊ice that moves very slowly
- 🏖️warm sand
🧊 ice that moves very slowly
Hint: Glaciers are huge rivers of ice found in cold, mountainous places.
