To solve this worksheet, we need to look at each item and decide if it is a solid, a liquid, or a gas.
Here is how we can tell the difference:
*
Solids keep their shape. You can hold them in your hand (like a rock or a pencil).
*
Liquids flow and take the shape of the container they are in (like water or juice).
*
Gases float around in the air. You usually cannot see them or hold them easily (like the air we breathe or steam).
Let's go through the list one by one:
1.
milk: It pours out of a carton. It is a
liquid.
2.
an ice cube: Even though it is made of water, it is frozen hard. It keeps its shape. It is a
solid.
3.
water vapor: This is water that has turned into steam or mist. It floats in the air. It is a
gas.
4.
a basketball: It is a round object you can bounce. It holds its shape. It is a
solid.
5.
oil: It pours and flows like water. It is a
liquid.
6.
a marshmallow: It is soft, but it still holds its shape until you squish it. It is a
solid.
7.
water: It flows and takes the shape of a cup. It is a
liquid.
8.
juice: Like milk and water, it pours. It is a
liquid.
9.
a piece of notebook paper: You can hold it, fold it, and it stays flat. It is a
solid.
10.
a piece of wood: It is hard and keeps its shape. It is a
solid.
11.
tomato soup: It is wet and pours from a can or bowl. It is a
liquid.
12.
oxygen (what humans breathe in): We breathe it in from the air. We can't see it. It is a
gas.
13.
helium in a balloon: Helium makes balloons float because it is lighter than air. It is a
gas.
14.
a cotton ball: It is very light and fluffy, but it is still stuff you can touch and hold. It is a
solid.
15.
carbon dioxide (what humans breathe out): When we exhale, we push out air. This air contains carbon dioxide. It is a
gas.

1. liquid
2. solid
3. gas
4. solid
