Step-by-step solution for: Physical Or Chemical Change Worksheet
Let's solve this step-by-step based on the worksheet titled "Physical and Chemical Changes". The goal is to color physical changes in red and chemical changes in blue, using the clues provided in the chart.
---
- Physical Change: A change in which no new substance is formed. The substance may change shape, size, or state, but its chemical composition stays the same. These are often reversible.
- Examples: Cutting paper, melting ice, boiling water.
- Chemical Change: A change in which a new substance is formed. This involves a chemical reaction. These are usually not reversible.
- Examples: Burning wood, rusting iron, cooking food.

We’ll go through each image and determine whether it’s a physical or chemical change based on the accompanying clues.
#### Row 1:
1. Scissors cutting paper → Shape change, no new substance
➤ Physical Change (Red)
2. Steam from a kettle → Water evaporating (state change)
➤ Physical Change (Red)
3. Canned fruit → No change in substance; just stored
➤ Physical Change (Red)
4. Crushed can → Shape changed, no new substance
➤ Physical Change (Red)
#### Row 2:
5. Bent wire → Only a shape change
➤ Physical Change (Red)
6. Mixture in glass → Likely dissolving sugar? No new substance
➤ Physical Change (Red)
7. Magnifying glass over a circle → Not a change at all (just viewing)
➤ No change → But likely meant to be Physical if it's just observing something
➤ Physical Change (Red)
8. Lighted match → Flame = combustion, new substances (CO₂, ash)
➤ Chemical Change (Blue)
#### Row 3:
9. Mixing bowl with spoon → Stirring ingredients (e.g., batter)? Could be physical unless reacting
➤ If no reaction, Physical Change (Red) — assume mixing without reaction
10. Campfire burning logs → Combustion → New substances (ash, CO₂)
➤ Chemical Change (Blue)
11. Slicing bread → Only shape change
➤ Physical Change (Red)
12. Broken shoe → Physical breakage, no new substance
➤ Physical Change (Red)
#### Row 4:
13. Ice cube in glass → Melting? Or freezing?
➤ Physical Change (Red) — changing state
14. Teapot boiling water → Water turning to steam
➤ Physical Change (Red)
15. Cube being cut into smaller cubes → Only shape change
➤ Physical Change (Red)
16. Car crashing → Deformation, but not chemical reaction
➤ Physical Change (Red)
17. Can’t be reversed → This clue suggests chemical change (since chemical changes are irreversible)
➤ Chemical Change (Blue)
#### Row 5:
18. Spoon stirring liquid → Mixing, no reaction
➤ Physical Change (Red)
19. A new substance is formed → Direct clue!
➤ Chemical Change (Blue)
20. Banana turning brown → Ripening = oxidation (chemical change)
➤ Chemical Change (Blue)
21. Fireworks exploding → Bright colors, gases, heat → chemical reactions
➤ Chemical Change (Blue)
22. Balloon popping → Rupture, no new substance
➤ Physical Change (Red)

- Color in RED: All images that represent physical changes (most of them).
- Color in BLUE: Images where a new substance is formed or the process can't be reversed.
---
- Physical changes involve shape, size, state — no new substance.
- Chemical changes involve reactions, often with heat, light, color change, gas, or odor — new substances form.
- Look for clues like “new substance”, “can’t be reversed”, or visible reactions (like fire, rust, explosion).
This worksheet helps students distinguish between the two types of changes using real-life examples!

🔍 Understanding the Concepts:
- Physical Change: A change in which no new substance is formed. The substance may change shape, size, or state, but its chemical composition stays the same. These are often reversible.
- Examples: Cutting paper, melting ice, boiling water.
- Chemical Change: A change in which a new substance is formed. This involves a chemical reaction. These are usually not reversible.
- Examples: Burning wood, rusting iron, cooking food.
