Help students understand weight and mass with this engaging balance scale activity featuring everyday classroom objects.

Let's solve this step-by-step by analyzing each balance scale in the image and determining whether the statement (implied by the scale) is True or False based on which side is heavier.

---

🔍 Understanding the Task

- We are comparing the mass of objects using a balance scale.
- If the scale tips to one side, that side has greater mass.
- The goal is to determine if the comparison shown is true or false — meaning: does the heavier object appear where it should?

We'll go through each pair:

---

1. Top Left: Ruler vs. Scissors

- Left side: Ruler
- Right side: Scissors
- Scale tips to the right → scissors are heavier

✔ So, scissors > ruler
→ The image shows scissors outweighing the ruler → this is True

➡️ Answer: True

---

2. Top Right: Glue vs. Eraser

- Left side: Glue bottle
- Right side: Eraser
- Scale tips to the right → eraser is heavier

But glue bottles are typically heavier than small erasers.
Wait — let’s look closely: the glue is on the left, eraser on the right, and the right side goes down → so eraser is heavier.

But realistically, a glue bottle is usually heavier than an eraser. So this comparison seems incorrect.

But we’re not judging realism — we’re judging the scale’s indication.

The scale says: eraser > glue
So the picture shows eraser heavier than glue.

But is that true? Probably not — glue is heavier.

Wait — but the task says: *"Use a balance scale to measure the mass... and colour if the picture is true or false."*

So we must assess whether the scale’s depiction matches reality.

But since this is likely for kids, we assume the scale shows the correct outcome — so we just need to evaluate whether the statement implied is accurate.

But there is no written statement — only the scale.

So the idea is: Is the scale balanced correctly based on real-world mass?

Let’s assume standard object masses:

Let’s go through all with realistic assumptions:

---

1. Ruler vs. Scissors

- A ruler (plastic or wood) is about 30–50g
- Scissors (metal blades) are heavier — often 80–100g

→ Scissors are heavier → scale tipping to scissors side is correct

✔ True

---

2. Glue vs. Eraser

- Glue bottle: ~50–60g (with liquid)
- Eraser: ~10–20g

→ Glue is heavier → so glue should be lower on the scale

But here, eraser side is down → implies eraser is heavier → false

✘ False

---

3. Calculator vs. Eraser

- Calculator: plastic, maybe 100–150g
- Eraser: ~10–20g

→ Calculator is much heavier → should tip to calculator side

Here, calculator is on the left, and left side is down → correct

✔ True

---

4. Paperclip vs. Pencil

- Paperclip: ~1g
- Pencil: ~5–10g

→ Pencil is heavier → should tip to pencil side

Here, pencil is on the right, and right side is down → correct

✔ True

---

5. Book vs. Crayon

- Book: small book, maybe 100–200g
- Crayon: ~5–10g

→ Book is heavier → should tip to book side

Here, book is on the left, and left side is down → correct

✔ True

---

6. Glue vs. Ruler

- Glue: ~50–60g
- Ruler: ~30–50g

→ Glue is heavier → should tip to glue side

Here, glue is on the left, and left side is down → correct

✔ True

---

7. Eraser vs. Pencil Sharpener

- Eraser: ~10–20g
- Pencil sharpener: plastic, maybe 20–40g

→ Sharpener is heavier → should tip to sharpener side

Here, sharpener is on the right, and right side is down → correct

✔ True

---

8. Pencil vs. Scissors

- Pencil: ~5–10g
- Scissors: ~80–100g

→ Scissors are much heavier → should tip to scissors side

Here, scissors are on the right, and right side is down → correct

✔ True

---

✔ Final Answers (Row by Row):

| Image | Comparison | Verdict |
|-------|------------|--------|
| 1 | Ruler vs Scissors | True |
| 2 | Glue vs Eraser | False |
| 3 | Calculator vs Eraser | True |
| 4 | Paperclip vs Pencil | True |
| 5 | Book vs Crayon | True |
| 6 | Glue vs Ruler | True |
| 7 | Eraser vs Sharpener | True |
| 8 | Pencil vs Scissors | True |

Wait! But earlier I said #2 is False, but let’s double-check.

Re-evaluate #2: Glue vs Eraser

- Glue bottle: ~60g
- Eraser: ~15g
- Scale shows eraser side down → means eraser is heavier → False

Yes, so #2 is False

All others are True

---

🟩 Final Answer:

Color the following as:

1. True
2. False
3. True
4. True
5. True
6. True
7. True
8. True

---

✔ Summary:

Only the second scale (Glue vs Eraser) is False because the glue is heavier, but the scale shows the eraser side going down — implying the eraser is heavier, which is incorrect.

All other scales show the heavier object on the lower side, matching real-world expectations.

🎯 Final Answer:
- True, False, True, True, True, True, True, True
