Science worksheet helping students classify everyday objects into solids, liquids, and gases.

Task Overview:

The task is to classify each of the provided images as a solid, liquid, or gas based on their properties. The definitions provided are:

- Solid: Keeps its shape and volume.
- Liquid: Can flow and change its shape.
- Gas: Changes its shape and fills the container it is in.

Solution:

#### Image 1: Open Book
- Classification: Solid
- Reasoning: A book maintains its shape and volume, which are characteristics of solids.

#### Image 2: Fizzy Pop Bottle
- Classification: Liquid (inside the bottle) and Gas (carbonation)
- Reasoning: The liquid inside the bottle can flow and change its shape, making it a liquid. However, the carbonation (fizzy part) represents gas, as it changes its shape and fills the space within the bottle.

#### Image 3: Cola Can
- Classification: Liquid (inside the can) and Gas (carbonation)
- Reasoning: Similar to the fizzy pop bottle, the cola inside the can is a liquid, while the carbonation represents gas.

#### Image 4: Apple
- Classification: Solid
- Reasoning: An apple maintains its shape and volume, which are characteristics of solids.

#### Image 5: Pencil
- Classification: Solid
- Reasoning: A pencil keeps its shape and volume, fitting the definition of a solid.

#### Image 6: Hot Air Balloon
- Classification: Gas
- Reasoning: The hot air inside the balloon is a gas because it changes its shape and fills the entire balloon.

#### Image 7: Cup of Coffee
- Classification: Liquid
- Reasoning: Coffee can flow and change its shape, which are characteristics of liquids.

#### Image 8: Teapot
- Classification: Solid (the teapot itself)
- Reasoning: The teapot is an object that maintains its shape and volume, making it a solid. Note: If the teapot contains water, the water would be classified as a liquid, but the question focuses on the teapot itself.

#### Image 9: Chocolate Bar
- Classification: Solid
- Reasoning: A chocolate bar maintains its shape and volume, fitting the definition of a solid.

#### Image 10: Honey Pot
- Classification: Liquid (honey inside the pot)
- Reasoning: Honey can flow and change its shape, which are characteristics of liquids.

#### Image 11: Melting Chocolate
- Classification: Liquid (melting chocolate)
- Reasoning: When chocolate melts, it becomes a liquid because it can flow and change its shape.

#### Image 12: Sandwich
- Classification: Solid
- Reasoning: A sandwich maintains its shape and volume, fitting the definition of a solid.
