Reading a Thermometer Worksheet - Free Printable

Let's solve this step-by-step based on the worksheet titled "What is the Temperature?".

Part 1: Show the temperature given for each thermometer

We are given three thermometers, each showing a temperature in one scale (Celsius or Fahrenheit), and we need to identify what temperature is shown on the thermometer.

But wait — actually, looking closely, the temperature is already labeled below each thermometer, so the task is likely to read the thermometer and verify that it matches the label.

Let’s go through each:

#### Thermometer 1
- Labeled: 30°C
- The mercury level is at 30°C on the Celsius scale.
✔ Correct.

#### Thermometer 2
- Labeled: 20°F
- But the scale shows Celsius on the left and Fahrenheit on the right.
- We need to check where 20°F falls on the Fahrenheit side.
- Looking at the Fahrenheit scale:
- 0°F is at the bottom
- 10°F, 20°F, 30°F, etc., go up
- The mercury is just above 0°F, but not quite at 20°F. Wait — let’s look carefully.

Actually, this thermometer shows the mercury level at approximately 20°F, which is about -6.7°C. But the label says 20°F, so we’re to confirm that the thermometer shows 20°F.

But the Celsius scale on the left would show around -6.7°C, which is correct for 20°F.

So yes, the thermometer shows 20°F, and the label is correct.

#### Thermometer 3
- Labeled: 120°F
- On the Fahrenheit scale, 120°F is high — near the top.
- Check the Celsius scale: 120°F = 48.9°C (approximately).
- The mercury level is just below 50°C, so yes, it matches.
✔ Correct.

So, all three thermometers are correctly labeled.

Part 2: Circle the temperature that matches the scene

Now we have three scenes with two temperature options each. We must choose the most appropriate temperature for each scenario.

---

#### Scene 1: Two kids playing baseball
- Options: 70°F or 70°C
- 70°C is extremely hot — about 158°F — dangerous, boiling water is 100°C.
- 70°F is about 21°C — mild, comfortable weather, perfect for outdoor sports like baseball.
✔ Correct answer: 70°F

---

#### Scene 2: A person building an igloo with a child inside
- Options: 0°C or 50°F
- Igloos are built in very cold conditions, typically below freezing.
- 0°C = 32°F — freezing point of water.
- 50°F = 10°C — cool but not cold enough for ice to stay solid.
- Since the scene shows an igloo made of snow/ice, the temperature must be at or below freezing.
- So 0°C is correct.
✔ Correct answer: 0°C

---

#### Scene 3: Two people playing in shallow water, possibly splashing
- Options: 30°F or 30°C
- 30°F = -1°C — very cold, water would be frozen.
- 30°C = 86°F — warm, pleasant swimming temperature.
- People are playing in water without coats — implies warm weather.
✔ Correct answer: 30°C

---

✔ Final Answers:

#### Part 1: Thermometers
- All labels match the readings.

#### Part 2: Match the scene
1. Baseball → 70°F
2. Igloo → 0°C
3. Water play → 30°C

📝 Summary of Circled Answers:

- 70°F
- 0°C
- 30°C

These are the temperatures that best match each scene.
