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

Task Overview:

The task requires identifying and coloring examples of physical changes in red and chemical changes in blue. Physical changes involve alterations in the form or appearance of a substance without changing its chemical composition, while chemical changes result in the formation of new substances with different properties.

Solution Approach:

1. Understand the Definitions:
- Physical Change: No new substance is formed; only the state, shape, or form of the substance changes.
- Chemical Change: A new substance is formed, often accompanied by energy changes (e.g., heat, light).

2. Analyze Each Image:
- Carefully examine each image to determine whether it represents a physical change or a chemical change based on the definitions above.

3. Coloring Guide:
- Red: Physical changes.
- Blue: Chemical changes.

Detailed Analysis of Each Image:

#### Row 1: "No new substance is formed"
- Scissors cutting paper: Physical change (shape change).
- Boiling water: Physical change (state change from liquid to gas).
- Bubbles in a glass: Physical change (gas bubbles forming but no new substance).
- Painting a shirt: Physical change (color change but no new substance).

#### Row 2: "Only a shape change"
- Bending a pipe: Physical change (shape change).
- Ice cubes in water: Physical change (state change from solid to liquid).
- Magnifying glass: Physical change (no chemical reaction).
- Match burning: Chemical change (new substances like carbon dioxide are formed).

#### Row 3: "Can be reversed"
- Mixing ingredients in a bowl: Physical change (can be separated back into original components).
- Fire burning: Chemical change (cannot be reversed; new substances are formed).
- Cutting bread: Physical change (shape change).
- Tearing paper: Physical change (shape change).

#### Row 4: "A solid is formed"
- Kettle boiling water: Physical change (water vapor condensing back to liquid).
- Melting ice cube: Physical change (state change from solid to liquid).
- Rocket launching: Chemical change (fuel burns, producing gases and other new substances).
- Explosion: Chemical change (new substances are formed).

#### Row 5: "A new substance is formed"
- Sugar dissolving in water: Physical change (sugar molecules dissolve but no new substance).
- Butter melting: Physical change (state change from solid to liquid).
- Fireworks exploding: Chemical change (new substances and energy are produced).
- Substance reacting in a flask: Chemical change (new substances are formed).

Final Coloring Guide:

- Red (Physical Changes):
- Scissors cutting paper
- Boiling water
- Bubbles in a glass
- Painting a shirt
- Bending a pipe
- Ice cubes in water
- Magnifying glass
- Mixing ingredients in a bowl
- Cutting bread
- Tearing paper
- Kettle boiling water
- Melting ice cube
- Sugar dissolving in water
- Butter melting

- Blue (Chemical Changes):
- Match burning
- Fire burning
- Rocket launching
- Explosion
- Fireworks exploding
- Substance reacting in a flask

Final Answer:

\[
\boxed{
\text{Red: All images except match burning, fire burning, rocket launching, explosion, fireworks exploding, and substance reacting in a flask.}
}
\]
