Grade 2 Science practice sheet
Nova Scotia Curriculum · from Gradelings · Name: ______________________
Question 1
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 2
A balloon is blown up. What does the balloon show?
🎈- Air takes up space
- Air has no weight and no space
- Air is a liquid
Air takes up space
Hint: The balloon gets bigger because air fills it.
Question 3
Put the butterfly's life cycle in order.
- 🐛caterpillar
- chrysalis
- 🦋butterfly
- 🥚egg
egg → caterpillar → chrysalis → butterfly
Hint: It starts as a tiny egg on a leaf. A caterpillar hatches, makes a chrysalis, then comes out as a butterfly.
Question 4
Which animal hatches from an egg?
- 🐮a calf
- 🐦a robin
- 🐶a puppy
🐦 a robin
Hint: Birds lay eggs. Most mammals are born alive.
Question 5
A rubber ball is…
- 💨a gas
- 💧a liquid
- ⚽a solid
⚽ a solid
Hint: A ball keeps its shape, so it is a solid.
Question 6
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 7
Which thing will a magnet pull?
🧲- 🥤a paper cup
- 📎a paper clip
- 🪵a wooden block
📎 a paper clip
Hint: Magnets pull on some metals, like iron and steel. Paper clips are made of steel!
Question 8
Does it save water or waste water?
Sort into: 👍 saves water · 👎 wastes water
- 🪣collect rain for plants
- 🛁take a really full bath
- 🚰let the tap drip
- 🪥turn off the tap while brushing
- 💦leave the hose running
- 🚿take a short shower
👍 saves water: collect rain for plants, turn off the tap while brushing, take a short shower · 👎 wastes water: take a really full bath, let the tap drip, leave the hose running
Hint: Using only the water you need saves it. Leaving water running wastes it.
Question 9
What happens to puddles after the sun comes out?
- They dry up
- They get bigger
- They turn into ice
They dry up
Hint: Heat makes the water evaporate.
Question 10
Put the frog's life cycle in order.
- tadpole with legs
- tadpole
- 🐸frog
- 🫧eggs in a pond
eggs in a pond → tadpole → tadpole with legs → frog
Hint: Frogs start as eggs in a pond. Tadpoles hatch, grow legs, and become frogs.
Answer key
- 1. Sun warms water and it rises → Clouds form → Rain or snow falls → Water collects in rivers and oceans (Water World)
- 2. Air takes up space (Air & Water for Life)
- 3. egg → caterpillar → chrysalis → butterfly (Life Cycles)
- 4. 🐦 a robin (Animal Life Cycles)
- 5. ⚽ a solid (Solids & Liquids)
- 6. mixture (Mixtures & Materials)
- 7. 📎 a paper clip (Push & Pull)
- 8. 👍 saves water: collect rain for plants, turn off the tap while brushing, take a short shower · 👎 wastes water: take a really full bath, let the tap drip, leave the hose running (Water World)
- 9. They dry up (Air & Water for Life)
- 10. eggs in a pond → tadpole → tadpole with legs → frog (Life Cycles)
