Students use the pointer scale to weigh each item shown on the worksheet.

To solve the problem of measuring the weight of each item shown in the image using the pointer scales, we need to carefully observe the position of the pointer on each scale and match it with the corresponding markings on the scale. Here's a step-by-step explanation:

Step 1: Understand the Scales

Each scale has a dial with markings that indicate the weight. The pointer on the dial points to a specific value, which represents the weight of the object placed on the scale.

- Scales in kg: These scales measure weight in kilograms (kg).
- Scales in g: These scales measure weight in grams (g).

Step 2: Analyze Each Scale

#### (1) First Scale (kg)
- The pointer is pointing directly at the "2" mark.
- Therefore, the weight is 2 kg.

#### (2) Second Scale (g)
- The pointer is pointing directly at the "50" mark.
- Therefore, the weight is 50 g.

#### (3) Third Scale (kg)
- The pointer is pointing directly at the "3" mark.
- Therefore, the weight is 3 kg.

#### (4) Fourth Scale (g)
- The pointer is pointing directly at the "70" mark.
- Therefore, the weight is 70 g.

#### (5) Fifth Scale (kg)
- The pointer is pointing directly at the "4" mark.
- Therefore, the weight is 4 kg.

#### (6) Sixth Scale (kg)
- The pointer is pointing directly at the "1" mark.
- Therefore, the weight is 1 kg.

Step 3: Summarize the Results

Here are the weights for each item based on the scales:

1. 2 kg
2. 50 g
3. 3 kg
4. 70 g
5. 4 kg
6. 1 kg

Final Answer

\[
\boxed{2 \text{ kg}, 50 \text{ g}, 3 \text{ kg}, 70 \text{ g}, 4 \text{ kg}, 1 \text{ kg}}
\]
