Question 1
Solid, liquid or gas? Tap an item, then tap its basket.
Sort into: 🧱 solid · 💧 liquid · 💨 gas
- 🥛milk
- 🌬️the air you breathe out
- 🍯maple syrup
- 🪨rock
- 🧊ice cube
- 🎈air in a balloon
🧱 solid: rock, ice cube · 💧 liquid: milk, maple syrup · 💨 gas: the air you breathe out, air in a balloon
Hint: Solids keep their shape. Liquids flow and take the shape of their container. Gases spread out to fill any space.
Question 2
What can Priya conclude from her experiment?
Seconds for a sugar cube to dissolve - Sugar can't dissolve in hot water
- Water temperature makes no difference
- Sugar dissolves faster in warmer water
- Sugar dissolves faster in colder water
Sugar dissolves faster in warmer water
Hint: Look at how the bars change as the water gets warmer. A shorter bar means less time to dissolve.
Question 3
Why do many pots have handles made of plastic or wood?
🍲- they are insulators, so the handle stays cool enough to hold
- they are conductors, so heat moves fast
- they make the food cook faster
they are insulators, so the handle stays cool enough to hold
Hint: Plastic and wood slow heat down. That keeps your hand safe while the metal pot heats the food.
Question 4
What is a magnet?
🧲- an object that attracts some metals
- a type of rock that floats
- a glowing light
- a kind of battery
an object that attracts some metals
Hint: Magnets pull things made of iron or steel.
Question 5
A wind turbine changes wind energy into…
- food
- ice
- electrical energy
- light only
electrical energy
Hint: Spinning blades make electricity.
Question 6
The top of a wave is the…
- crest
- base
- trough
- floor
crest
Hint: The highest point.
Question 7
Why do you hear your voice echo in an empty gym but not in a room full of furniture?
🏟️- furniture makes sound louder
- sound turns into light in the gym
- the gym is colder
- hard, empty surfaces reflect sound, and soft things absorb it
hard, empty surfaces reflect sound, and soft things absorb it
Hint: Furniture absorbs sound.
Question 8
Why are electrical wires covered in plastic?
- Plastic makes electricity stronger
- Plastic is a conductor
- Plastic is an insulator, so it keeps people and parts safe
Plastic is an insulator, so it keeps people and parts safe
Hint: The metal inside carries current. The coating protects.
Question 9
Put the water cycle in order. Start with the sun warming the water.
- ☁️Clouds form
- ☀️Sun warms water and it rises
- 🌧️Rain or snow falls
- 🌊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 10
A rabbit eats grass. The energy in the grass came from…
- the rabbit
- the soil
- the rain
- sunlight
sunlight
Hint: Plants store the sun's energy.

- 1. 🧱 solid: rock, ice cube · 💧 liquid: milk, maple syrup · 💨 gas: the air you breathe out, air in a balloon (Particles & Mass)
- 2. Sugar dissolves faster in warmer water (Mixtures & Solutions)
- 3. they are insulators, so the handle stays cool enough to hold (Thermal Energy)
- 4. an object that attracts some metals (Gravity & Magnets)
- 5. electrical energy (Energy, Speed & Collisions)
- 6. crest (Waves & Codes)
- 7. hard, empty surfaces reflect sound, and soft things absorb it (Sound)
- 8. Plastic is an insulator, so it keeps people and parts safe (Circuits)
- 9. Sun warms water and it rises → Clouds form → Rain or snow falls → Water collects in rivers and oceans (Water World)
- 10. sunlight (Energy from the Sun)
