Question 1
Kenji has a dry mix of iron filings, sand and salt. Put his separation steps in order.
- 🥄Add water and stir until the salt dissolves
- ☀️Let the water evaporate to leave the salt
- 🧲Run a magnet through the dry mix to pull out the iron
- ☕Pour it through a filter to catch the sand
Run a magnet through the dry mix to pull out the iron → Add water and stir until the salt dissolves → Pour it through a filter to catch the sand → Let the water evaporate to leave the salt
Hint: Use the magnet while the mix is still dry. Then dissolve the salt, filter out the sand, and evaporate the water to get the salt back.
Question 2
Which of these is NOT matter?
- Air in a balloon
- A drop of juice
- A puff of smoke
- A beam of light
A beam of light
Hint: Matter has mass and volume. Light is a form of energy.
Question 3
Put these in order from LEAST thermal energy to MOST.
- ♨️Water vapor (gas)
- 💧Liquid water
- 🧊Ice (solid water)
Ice (solid water) → Liquid water → Water vapor (gas)
Hint: A solid has the least energy and its particles move the least. A gas has the most.
Question 4
A student crushes a can. This is a…
- chemical change
- change of state
- physical change
physical change
Hint: The shape changed, but it is still the same metal.
Question 5
Mass is the amount of…
- space something takes up
- heat in something
- matter in something
- force on something
matter in something
Hint: Mass is the amount of matter in a solid, liquid or gas.
Question 6
A warm front is when…
- warm air moves over cooler air
- winds stop
- cold air pushes under warm air
warm air moves over cooler air
Hint: The warm air slides up over the cold air.
Question 7
Which gas do plants take in from the air to make food?
- Smoke
- Helium
- Carbon dioxide
- Oxygen
Carbon dioxide
Hint: CO₂.
Question 8
Decomposers return nutrients to the…
- sun
- moon
- soil
- clouds only
soil
Hint: Plants use them again.
Question 9
Which question defines a clear problem?
- Is this fun?
- What color is nice?
- Who is tallest?
- How can we keep an egg safe if dropped 2 m?
How can we keep an egg safe if dropped 2 m?
Hint: Specific and testable.
Question 10
The sun looks brighter than other stars because…
- it is much closer to Earth
- it is a planet
- other stars are dim
- it is the biggest star
it is much closer to Earth
Hint: Distance matters.
Answer key
- 1. Run a magnet through the dry mix to pull out the iron → Add water and stir until the salt dissolves → Pour it through a filter to catch the sand → Let the water evaporate to leave the salt (Solutions & Mixtures)
- 2. A beam of light (Solid, Liquid, Gas)
- 3. Ice (solid water) → Liquid water → Water vapor (gas) (Changes of State)
- 4. physical change (Physical or Chemical?)
- 5. matter in something (Measuring Matter)
- 6. warm air moves over cooler air (Weather and the Water Cycle)
- 7. Carbon dioxide (Energy from the Sun)
- 8. soil (Matter Moves in Ecosystems)
- 9. How can we keep an egg safe if dropped 2 m? (Engineering Challenges)
- 10. it is much closer to Earth (Sun, Stars & Shadows)
