Answer:
Certainly! Here are examples of physical and chemical changes observed in a living room and garden setting:
### Living Room:
**Physical Changes:**
1. **Melting Ice Cube:** Ice cubes placed on a table melt into water as they absorb heat from the surroundings.
2. **Breaking a Pencil:** Snapping a pencil in half results in two smaller pieces, but the material remains graphite and wood.
3. **Tearing Paper:** Ripping a piece of paper into smaller fragments changes its size and shape without altering its composition.
4. **Crushing Candy:** Crushing a candy bar into smaller pieces changes its form, but it remains the same substance.
5. **Mixing Salt and Water:** Stirring salt into water dissolves the salt particles, but they remain salt chemically.
6. **Changing TV Channels:** Switching channels on a TV changes what is displayed on the screen, but it does not alter the TV itself.
**Chemical Changes:**
1. **Burning Candle:** Lighting a candle causes wax to melt and eventually burn, producing heat, light, and carbon dioxide.
2. **Rusting of Metal:** If there is exposed metal in the living room, like on furniture or decorative items, it can rust over time due to exposure to air and moisture.
3. **Baking Cookies:** Mixing ingredients like flour, sugar, and butter and then baking them causes a chemical reaction that changes the dough into cookies.
4. **Bleaching Fabric:** Using a bleach solution to remove stains from fabric chemically alters the color of the fabric.
5. **Paint Drying:** Applying paint to walls or furniture results in a chemical change as the paint dries and forms a solid film.
6. **Wood Burning in Fireplace:** Burning wood in a fireplace produces ash, heat, and smoke as a result of a combustion reaction.
### Garden:
**Physical Changes:**
1. **Watering Plants:** Pouring water onto plants changes their moisture content without altering their chemical composition.
2. **Cutting Grass:** Using a lawnmower to cut grass changes its height and appearance but does not change it chemically.
3. **Digging Soil:** Turning soil with a shovel changes its structure and aerates it, but it remains soil.
4. **Plucking Flowers:** Removing flowers from a plant changes their position and appearance but not their chemical makeup.
5. **Trimming Hedges:** Pruning hedges changes their shape and size without altering the plant's chemical composition.
6. **Moving Garden Rocks:** Rearranging rocks in a garden changes their position but does not change them chemically.
**Chemical Changes:**
1. **Composting:** Organic matter in a compost pile decomposes over time due to bacterial action, forming nutrient-rich compost.
2. **Fertilizing Plants:** Applying fertilizer to soil provides essential nutrients to plants, promoting growth and development.
3. **Rusting Garden Tools:** Tools left outside can rust over time due to exposure to moisture and oxygen in the air.
4. **Planting Seeds:** Seeds germinate and grow into plants as a result of metabolic processes within the seeds.
5. **Rotting Fruit:** Fruit left on the ground or composting can undergo decay due to microbial activity, changing its chemical composition.
6. **Burning Leaves:** Burning leaves produces ash and smoke as a result of combustion, changing the leaves' chemical composition.
These observations illustrate the distinction between physical changes, where the substance retains its chemical identity, and chemical changes, where new substances are formed.
