Measure the length of each object using clips on this educational worksheet.

To solve the problem of measuring the length of each object using paper clips, we need to follow these steps:

Step 1: Understand the Task

The task requires measuring the length of each object shown in the image using paper clips. The goal is to determine how many paper clips fit along the length of each object.

Step 2: Measure Each Object

We will estimate the length of each object by comparing it to the size of a single paper clip. Assume the length of one paper clip is known or can be visually estimated.

#### Object (1): Brush
- The brush appears to be slightly longer than 3 paper clips.
- Estimated Length: About 3 paper clips.

#### Object (2): Scissors
- The scissors are open and span a length that is approximately equal to 4 paper clips.
- Estimated Length: About 4 paper clips.

#### Object (3): Pencil
- The pencil is about the same length as 5 paper clips.
- Estimated Length: About 5 paper clips.

#### Object (4): Eraser
- The eraser is much shorter and fits within the length of 1 paper clip.
- Estimated Length: About 1 paper clip.

#### Object (5): Pen
- The pen is slightly longer than 4 paper clips.
- Estimated Length: About 4 paper clips.

#### Object (6): Mechanical Pencil
- The mechanical pencil is about the same length as 4 paper clips.
- Estimated Length: About 4 paper clips.

#### Object (7): Spring
- The spring is quite long and spans approximately 7 paper clips.
- Estimated Length: About 7 paper clips.

Step 3: Record the Results

Now, we fill in the blanks for each object with the estimated number of paper clips:

1. Brush: About 3 paper clips
2. Scissors: About 4 paper clips
3. Pencil: About 5 paper clips
4. Eraser: About 1 paper clip
5. Pen: About 4 paper clips
6. Mechanical Pencil: About 4 paper clips
7. Spring: About 7 paper clips

Final Answer:

\[
\boxed{
\begin{array}{ll}
\text{(1) Brush:} & \text{About 3 paper clips} \\
\text{(2) Scissors:} & \text{About 4 paper clips} \\
\text{(3) Pencil:} & \text{About 5 paper clips} \\
\text{(4) Eraser:} & \text{About 1 paper clip} \\
\text{(5) Pen:} & \text{About 4 paper clips} \\
\text{(6) Mechanical Pencil:} & \text{About 4 paper clips} \\
\text{(7) Spring:} & \text{About 7 paper clips} \\
\end{array}
}
