Exact 20-Item Distribution
5 Phys Prop 5 Chem Prop 5 Phys Change 5 Chem Change
Phys Prop
Observable trait or measurement without altering matter identity.
Clues: measures, has color, density, boiling pt
Chem Prop
Potential or ability to react (or not react) to form new substances.
Clues: has ability to react, flammable, inert
Phys Change
Active process altering state, size, or shape; identity unchanged.
Clues: crushing, boiling, freezing, dissolving
Chem Change
Active chemical reaction actively breaking/forming bonds to make new matter.
Clues: burning, rusting, gas fizzing, reacting

7
An apple will oxidize when exposed to air
Fresh apple slices have the chemical tendency to react with oxygen and turn brown
Chem prop
Susceptibility to oxidation
8
Neon is inert (unreactive)
Neon gas is chemically inert, meaning it lacks the ability to bond with other elements
Chem prop
Inability to react is a property
9
H₂O(l) → H₂O(g)
Liquid water boiling and changing into water vapor gas (H₂O molecules remain unchanged)
Phys change
Liquid to gas phase change
10
The boiling point of acetone is 56°C
Acetone liquid has an established boiling temperature of 56°C
Phys prop
Characteristic thermal constant

1) Teeth crushing bread into smaller crumbs Phys change
6) Platinum has a reflective metallic luster Phys prop
2) Logs burning in a fire to produce ash and smoke Chem change
7) Apple slices have the ability to brown in air Chem prop
3) Nitrogen reacting with hydrogen to make ammonia Chem change
8) Neon is inert (lacks ability to form chemical bonds) Chem prop
4) A metal cube has a measured volume of 32.15 cm³ Phys prop
9) Liquid water boiling into steam: H₂O(l) → H₂O(g) Phys change
5) Cesium has the ability to react violently in water Chem prop
10) Acetone has a measured boiling point of 56°C Phys prop
Rule of thumb for students: "Has the ability / measures / is" = Property | "-ing actions happening right now" = Change. Page 1 of 2

Teacher Tip How to Update Your Google Sheets Pixel Art Without Breaking Formulas
1. Safe Question Editing Only edit the text inside the question cells (Column B & Column G). Do not alter or shift any answer cells where conditional formulas are attached.
2. Keep Exact Case / Spacing Ensure students type: Phys prop, Chem prop, Phys change, or Chem change as programmed.
3. Balanced Key Verification All 20 questions retain their exact original answer key designations, guaranteeing that the hidden pixel art image reveals normally!
