🌡️ Temperature Scale Conversion Activity 🌡️
🎯 Objective:
To understand how to convert temperature readings between Celsius, Fahrenheit, and Kelvin scales using formulas and practical demonstration.
🧠 Materials Required:
- Thermometers (any available scale)
- Calculator
- Conversion chart
- Observation sheet
🧩 Activity Steps:
- Students are divided into groups of 3 — each representing one temperature scale.
- Each group records the temperature of warm and cold water using their thermometer scale.
- They use the formulas to convert to the other two scales.
- Groups share their converted values and discuss the difference in readings.
🧮 Interactive Temperature Converter
Enter a value in any one of the boxes and click Convert.
💬 Discussion & Life Connection:
Each scale gives a different number for the same temperature — just like people have different opinions, but truth remains one. Respect every scale (and every view)!
❓ Question & Answer Time
- Formula to convert °C to °F? F = (9/5 × C) + 32
- Formula to convert °F to °C? C = (F − 32) × 5/9
- Formula to convert °C to K? K = C + 273
- What is 0°C in Kelvin? 273 K
- Convert 212°F to °C. 100°C
- Convert 300 K to °C. 27°C
- Which scale is absolute? Kelvin
- Freezing point of water in °F? 32°F
- Who developed the Celsius scale? Anders Celsius
- Normal human body temperature in °C? 37°C
🎲 Group Challenge:
Teacher gives one scale reading (e.g. 104°F). Each group must quickly convert it into °C and K. Fastest correct answer wins points!
📝 Conclusion:
- Temperature scales are different ways to express the same concept.
- Conversion helps in universal communication of temperature data.
- Kelvin is used in science; Celsius in daily life; Fahrenheit in some countries.
