Grade 2 Science Worksheet: Classifying Solids, Liquids, and Gases

Problem Overview:

The task is to classify the given items into three categories: solid, liquid, and gas. Additionally, you need to provide your own example for each category.

Key Definitions:

- Solids: Keep their shape (e.g., chair, book).
- Liquids: Take the shape of their container (e.g., juice, milk).
- Gases: Spread out to fill the space they are in (e.g., air, steam).

Items Provided:

1. Air
2. Chair
3. Popsicle
4. Helium
5. Juice
6. Steam
7. Book
8. Milk
9. Rain
10. Apple

Solution:

#### Step 1: Classify Each Item
We will analyze each item based on its physical state:

1. Air: Gas (spreads out to fill space)
2. Chair: Solid (keeps its shape)
3. Popsicle: Solid (keeps its shape)
4. Helium: Gas (spreads out to fill space)
5. Juice: Liquid (takes the shape of its container)
6. Steam: Gas (spreads out to fill space)
7. Book: Solid (keeps its shape)
8. Milk: Liquid (takes the shape of its container)
9. Rain: Liquid (drops of water that take the shape of their container or fall as droplets)
10. Apple: Solid (keeps its shape)

#### Step 2: Write the Items in the Correct Columns
- Solid: Chair, Popsicle, Book, Apple
- Liquid: Juice, Milk, Rain
- Gas: Air, Helium, Steam

#### Step 3: Provide Your Own Example for Each Category
- Solid: Rock
- Liquid: Water
- Gas: Oxygen

Final Answer:

```
Solid: Chair, Popsicle, Book, Apple
Liquid: Juice, Milk, Rain
Gas: Air, Helium, Steam

Your Own Examples:
Solid: Rock
Liquid: Water
Gas: Oxygen
```
