📚 Topic Summary
Reading a thermometer is like decoding a secret message about how hot or cold something is! Thermometers use scales, most commonly Fahrenheit (°F) or Celsius (°C), to show the temperature. The liquid inside the thermometer rises or falls depending on the temperature, and where it stops tells us the temperature reading. Knowing how to read a thermometer is super helpful in everyday life, from knowing what to wear outside to understanding science experiments. So, let's learn how to crack the code!
