Since no specific question was asked about the image, I will assume the task is to categorize each item as either a
Physical Change or a
Chemical Change, which is the standard educational objective for this type of worksheet.
Here is the step-by-step classification:
1.
Cutting an apple: Physical change (only size/shape changes).
2.
Baking a cookie: Chemical change (ingredients react to form new substances; cannot be reversed).
3.
Lighting a match: Chemical change (burning/fire creates heat and light).
4.
Melting ice: Physical change (state change from solid to liquid).
5.
Roasting a marshmallow: Chemical change (browning/caramelizing).
6.
Freezing water: Physical change (state change from liquid to solid).
7.
Burning a candle: Chemical change (wax burning).
8.
Dissolving sugar: Physical change (sugar is still sugar, just mixed with water).
9.
Ripping paper: Physical change (only size changes).
10.
Slicing bread: Physical change (only size changes).
11.
Boiling water: Physical change (state change to gas).
12.
Crushing a can: Physical change (shape changes).
13.
Breaking a mirror: Physical change (object breaks into pieces).
14.
A decaying leaf: Chemical change (decomposition).
15.
Frying an egg: Chemical change (heat changes the protein structure).
16.
Mixing vinegar and baking soda: Chemical change (creates gas bubbles).
17.
A rusting bike: Chemical change (iron reacts with oxygen).
18.
Burning wood: Chemical change (fire/combustion).
19.
Cutting grass: Physical change (size changes).
20.
Digesting food: Chemical change (acids/enzymes break down food).
Final Answer:
Physical Changes:
* Cutting an apple
* Melting ice
* Freezing water
* Dissolving sugar
* Ripping paper
* Slicing bread
* Boiling water
* Crushing a can
* Breaking a mirror
* Cutting grass
Chemical Changes:
* Baking a cookie
* Lighting a match
* Roasting a marshmallow
* Burning a candle
* A decaying leaf
* Frying an egg
* Mixing vinegar and baking soda
* A rusting bike
* Burning wood
* Digesting food
