Particle box before and after, two changes.
4.
In the particle boxes, what kind of change is Change A, Jun?
- Chemical: brand-new particles
- Nothing changed in the box
- Physical: the same particles
5.
In the particle boxes, what kind of change is Change B, Kira?
Use the picture in question 4.
- Physical: they melt
- Chemical: new pairs form
- Physical: they spread out
6.
In the particle boxes, what happens to the atoms in Change B, Luz?

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.
