Problem Analysis:
The task involves identifying the correct sequence of steps for cleaning and preparing a microscope slide. The provided options are:
1.
Option A:
- Place the slide on the stage.
- Wipe the slide with a tissue.
- Add a drop of water to the slide.
2.
Option B:
- Wipe the slide with a tissue.
- Place the slide on the stage.
- Add a drop of water to the slide.
3.
Option C:
- Add a drop of water to the slide.
- Wipe the slide with a tissue.
- Place the slide on the stage.
4.
Option D:
- Place the slide on the stage.
- Add a drop of water to the slide.
- Wipe the slide with a tissue.
Solution Explanation:
To solve this problem, we need to understand the logical sequence of steps required to clean and prepare a microscope slide. Here is the reasoning step by step:
#### Step 1: Clean the Slide
- Before placing the slide on the microscope stage or adding any liquid, it is essential to ensure that the slide is clean. This prevents debris or contaminants from interfering with the observation.
- Therefore, the first step should be to
wipe the slide with a tissue.
#### Step 2: Place the Slide on the Stage
- Once the slide is clean, it can be placed on the microscope stage. This ensures that the slide is ready for further preparation or observation.
- The second step should be to
place the slide on the stage.
#### Step 3: Add a Drop of Water (if necessary)
- After the slide is in place, you may add a drop of water or another liquid (e.g., a sample) depending on the experiment. This step is typically done after the slide is set up on the stage.
- The third step should be to
add a drop of water to the slide.
Correct Sequence:
Based on the above reasoning, the correct sequence of steps is:
1. Wipe the slide with a tissue.
2. Place the slide on the stage.
3. Add a drop of water to the slide.
This matches
Option B.
Final Answer:
$$
\boxed{B}
