Physical and Chemical Changes Craftivity - The Owl Teacher - Free Printable

To solve this task, we need to understand the difference between physical and chemical changes:

- Physical Change: This is when a substance changes its form but not its identity. No new substance is created. Examples include cutting paper, melting ice, or dissolving sugar in water. These changes can often be reversed.

- Chemical Change: This is when a substance changes into a completely different substance with new properties. New substances are formed. Examples include burning wood, rusting iron, or baking a cake. These changes usually cannot be reversed.

Now let’s go through each item in the chart one by one and decide whether it’s a physical change (color red) or a chemical change (color blue):

1. “no new substance is formed” → This describes a physical change → Color RED
2. Scissors cutting paper → Physical change → Color RED
3. Toaster popping up toast → The bread is toasted — that’s a chemical change (burning/toasting creates new substances) → Color BLUE
4. Dissolving candy in water → Physical change (candy still exists, just dissolved) → Color RED
5. Pouring juice from carton to glass → Physical change (just moving liquid) → Color RED

6. Bending a metal rod → Physical change (shape changed, material same) → Color RED
7. Ice cubes melting in water → Physical change (solid to liquid, still H₂O) → Color RED
8. “only a shape change” → Describes physical change → Color RED
9. Frying eggs in pan → Chemical change (eggs cook and change permanently) → Color BLUE
10. Lighting a match → Chemical change (burning produces heat, light, ash) → Color BLUE

11. Mixing ingredients in bowl → If just mixing without cooking/baking, it’s physical → Color RED
12. Campfire burning logs → Chemical change (wood turns to ash, smoke, CO₂) → Color BLUE
13. Cutting bread → Physical change (still bread, just smaller pieces) → Color RED
14. “can be reversed” → Typically describes physical changes → Color RED
15. Crushed soda can → Physical change (shape changed, material same) → Color RED

16. “a solid is formed” → Could mean precipitation in chemistry — often chemical → But if it’s freezing water into ice, it’s physical. Looking at context, likely refers to forming a new solid via reaction → Color BLUE
17. Boiling kettle (steam) → Physical change (water vapor, still H₂O) → Color RED
18. Melting butter → Physical change (solid to liquid, still butter) → Color RED
19. Smashed toy car → Physical change (broken, but same material) → Color RED
20. “can’t be reversed” → Usually chemical changes → Color BLUE

21. Spoon stirring drink → Physical change (mixing) → Color RED
22. “a new substance is formed” → Defines chemical change → Color BLUE
23. Peeling banana → Physical change (just removing peel) → Color RED
24. Fireworks exploding → Chemical change (explosion, color, heat = new substances) → Color BLUE
25. Balloon inflating with gas → Physical change (gas fills balloon, no new substance) → Color RED

✔ Final coloring plan:
- Red (Physical Changes): Items 1, 2, 4, 5, 6, 7, 8, 11, 13, 14, 15, 17, 18, 19, 21, 23, 25
- Blue (Chemical Changes): Items 3, 9, 10, 12, 16, 20, 22, 24

Final Answer:
Color the following examples of physical changes in red: “no new substance is formed”, scissors cutting paper, dissolving candy, pouring juice, bending metal rod, ice melting, “only a shape change”, mixing ingredients, cutting bread, “can be reversed”, crushed can, boiling kettle, melting butter, smashed toy, spoon stirring, peeling banana, balloon inflating.
Color the following examples of chemical changes in blue: toaster making toast, frying eggs, lighting match, campfire, “a solid is formed” (if from reaction), “can’t be reversed”, “a new substance is formed”, fireworks.
