5.6 g of iron rusts completely by joining with 2.4 g of oxygen from the air. What mass of rust forms, Ari?
11.2 g of iron rusts completely by joining with 4.8 g of oxygen from the air. What mass of rust forms, Bo?
2.8 g of iron rusts completely by joining with 1.2 g of oxygen from the air. What mass of rust forms, Esme?
4.
Milk left out turns sour and lumpy. What does that show, Jun?
- A physical change
- A chemical change
- A change of state
5.
Batter of egg and flour bakes into a firm, brown cake. What kind of change is that, Kira?
- Physical: it just dries out
- Physical: the batter just melts
- Chemical: it can't be unbaked
6.
A candle flame gives off light and heat. What do these signs suggest, Luz?
- Just melting of the wax
- A chemical change
- No change
7.
Is water's boiling point an intensive or an extensive property, Noah?
- Extensive
- A chemical property
- Intensive
8.
Why do intensive properties help identify a substance, Pia?
- They are easy to weigh
- They don't depend on amount
- They change with the sample's size
9.
A candle burns inside a sealed jar on a balance. What happens to the reading, Tala?
- It rises a lot
- It stays the same
- It drops a lot
10.
Why does a nail weigh more after rusting, Zee?
- Water makes the nail swell up
- Oxygen from the air joins it
- New atoms grow on it

Physical and chemical properties and changes. Every version has 10 questions, and the answer key prints on the second page.

I can sort changes as physical (same substance) or chemical (new substances), using particle drawings as evidence.
I can name signs of a chemical change: new color or smell, light, heat or a new solid.
I can tell physical from chemical properties, and intensive from extensive ones.
I can use mass conservation: rust weighs iron + oxygen, and a burning candle's mass leaves as gases.

Standard: none (FL)

physical change: A change in form or state with no new substance

chemical change: A change that makes new substances

chemical property: How a substance reacts, such as whether it rusts

intensive property: A property that doesn't depend on amount, like density

extensive property: A property that depends on amount, like mass

Your child divided volume by mass. Density is mass ÷ volume.

Your child took the oxygen away. In rusting, iron joins with oxygen, so the rust weighs iron + oxygen.

Your child halved the density. Cutting a block halves its mass and volume, so the density stays the same.

What is the most common mistake with physical and chemical properties and changes?

Your child divided volume by mass. Density is mass ÷ volume.
