Matter Worksheets - Solid, Liquid, and Gas - Free Printable

I'll solve this worksheet problem by identifying whether each item is a solid, liquid, or gas, and then completing the sentences with the correct terms.

First, let me look closely at the image to understand what I need to do. The worksheet has two main sections:
1. A list of 16 items where I need to classify each as solid, liquid, or gas
2. Three sentences to complete with the words "solid," "liquid," or "gas"

Let me start by working through the first section - classifying each item.

For milk: Milk is a liquid.
For oxygen: Oxygen is a gas at room temperature.
For fish: Fish are solid (living organisms with definite shape).
For cookie: A cookie is a solid.
For pencil: A pencil is a solid.
For maple syrup: Maple syrup is a liquid.
For shampoo: Shampoo is typically a liquid.
For carbon dioxide: Carbon dioxide is a gas at room temperature.
For ice cube: An ice cube is a solid (frozen water).
For paint: Paint is a liquid.
For oil: Oil is a liquid.
For salt: Salt is a solid (crystalline substance).
For water vapor: Water vapor is a gas.
For gasoline: Gasoline is a liquid.
For helium: Helium is a gas.
For sand: Sand is a solid (composed of small solid particles).

Now for the second section, I need to complete the sentences:

"A _______ has a definite shape. It does not take the shape of its container. It also has a definite volume because it can be measured."
This describes a solid.

"A _______ does not have a definite shape. It takes the shape of its container. It also has a definite volume because it can be measured."
This describes a liquid.

"A _______ does not have a definite shape. It sometimes takes the shape of its container and sometimes flies freely around you. These particles are not connected to each other and takes up whatever space is available."
This describes a gas.

Let me now provide the complete solution.

Section 1: Classify each item

1. milk - liquid
2. cookie - solid
3. oxygen - gas
4. fish - solid
5. pencil - solid
6. maple syrup - liquid
7. shampoo - liquid
8. carbon dioxide - gas
9. ice cube - solid
10. paint - liquid
11. oil - liquid
12. salt - solid
13. water vapor - gas
14. gasoline - liquid
15. helium - gas
16. sand - solid

Section 2: Complete each sentence

A solid has a definite shape. It does not take the shape of its container. It also has a definite volume because it can be measured.

A liquid does not have a definite shape. It takes the shape of its container. It also has a definite volume because it can be measured.

A gas does not have a definite shape. It sometimes takes the shape of its container and sometimes flies freely around you. These particles are not connected to each other and takes up whatever space is available.
