This worksheet helps students distinguish between physical and chemical changes by circling examples and describing property changes.

Let’s go step by step to solve this worksheet.

First, we need to understand what a physical change is.
A physical change means the matter looks different — maybe its shape, size, or state (like solid to liquid) — but it’s still the same kind of stuff. It doesn’t turn into something new.

For example:
- Melting ice → still water, just in liquid form → physical change.
- Breaking glass → still glass, just in pieces → physical change.
- Burning wood → turns into ash and smoke → that’s a NEW substance → chemical change (not physical).

So for Part 1: We circle only the items that are physical changes.

Let’s go through each one:

✔ clay rolled into a ball → still clay, just shaped differently → PHYSICAL
✔ wood that’s been chopped → still wood, just smaller pieces → PHYSICAL
✔ broken glass → still glass, just shattered → PHYSICAL
✘ burned wood → turned into ash/smoke → CHEMICAL (not physical)
✔ ice melted → still H₂O, just liquid now → PHYSICAL
✘ fried egg → cooking changes the proteins → CHEMICAL
✔ paper that has been cut → still paper, just smaller → PHYSICAL
✘ fireworks exploded → creates light, sound, gases → CHEMICAL
✘ rusted iron → iron + oxygen = rust (new substance) → CHEMICAL
✘ food spoiled → bacteria changed it → CHEMICAL
✔ a crushed can → still metal, just squished → PHYSICAL
✔ folded clothes → still fabric, just arranged differently → PHYSICAL

So the ones to circle are:
- clay rolled into a ball
- wood that’s been chopped
- broken glass
- ice melted
- paper that has been cut
- a crushed can
- folded clothes

Part 2: Give an example where each property of matter has changed.

We’re looking for simple examples of physical changes that affect these properties.

→ size: Cutting a piece of paper in half → now it’s smaller.
→ shape: Rolling clay into a snake → same amount, different shape.
→ weight: This is tricky! In physical changes, weight usually stays the same unless you add/remove matter. But if you break off a piece of chocolate, the remaining piece weighs less → so “breaking off a piece of candy” works.
*(Note: Weight change here means the object’s measured weight changed because part was removed — not because gravity changed.)*
→ color: Painting a toy car red → the color changed, but it’s still the same toy → physical change.
*(Alternative: Mixing paint colors — also physical. Or even dyeing fabric.)*

Wait — let’s double-check “weight”. If you have a block of cheese and cut off a slice, the original block now weighs less. That’s a physical change affecting weight. Yes, that works.

Another option for color: Crayon melting and mixing colors — still wax, just different color appearance.

But keep it simple for a student.

Final choices:

- size: cutting a sheet of paper in half
- shape: bending a wire into a circle
- weight: breaking a cookie in half (each half weighs less than whole)
- color: coloring a drawing with markers (paper changes color, still paper)

Actually, for “weight”, some teachers might say weight doesn’t change in physical changes unless mass is removed. So better to use: “removing a scoop of ice cream from a cone” — the cone now weighs less. Still physical.

Or even simpler: “taking a bite out of an apple” — the apple weighs less after. Physical change.

Yes.

Now, let’s write the final answers clearly.

Final Answer:

Part 1: Circle these examples of physical changes:
- clay rolled into a ball
- wood that’s been chopped
- broken glass
- ice melted
- paper that has been cut
- a crushed can
- folded clothes

Part 2: Examples for each property change:
- size: cutting a piece of string in half
- shape: molding playdough into a star
- weight: taking a bite out of a sandwich
- color: painting a rock blue
