Label the diagram to identify the tools used to separate rice, sand, and paper clips.

Problem Analysis:

The task is to label a diagram that shows the process of separating a mixture of rice, sand, and paper clips using specific tools: magnet, large sieve, and small sieve. The goal is to identify which tool corresponds to each step in the separation process.

Key Concepts:

1. Paper clips: These are magnetic and can be separated using a magnet.
2. Rice: This is larger than sand and can be separated using a large sieve.
3. Sand: This is smaller than rice and can be separated using a small sieve.

Step-by-Step Solution:

#### 1. Magnet (Paper Clips)
- Paper clips are magnetic, so they can be separated from the mixture using a magnet.
- In the diagram, the magnet is shown attracting some objects. These objects must be the paper clips.
- Label the box connected to the magnet as "Paper clips".

#### 2. Large Sieve (Rice)
- Rice is larger than sand, so it can be separated using a large sieve.
- The diagram shows a container with a mixture being poured into a large sieve. The material that remains in the sieve after sieving must be rice.
- Label the box connected to the large sieve as "Rice".

#### 3. Small Sieve (Sand)
- Sand is smaller than rice, so it can be separated using a small sieve.
- After passing through the large sieve, the remaining material (sand) will be further separated using a small sieve.
- Label the box connected to the small sieve as "Sand".

Final Labels:

- The magnet attracts paper clips, so label the box connected to the magnet as "Paper clips".
- The large sieve retains rice, so label the box connected to the large sieve as "Rice".
- The small sieve retains sand, so label the box connected to the small sieve as "Sand".

Labeled Diagram:

1. Magnet → Paper clips
2. Large sieve → Rice
3. Small sieve → Sand

Final Answer:

\[
\boxed{
\text{Magnet: Paper clips, Large sieve: Rice, Small sieve: Sand}
}
\]
