Choose the more reasonable temperature

key notes :

Understanding Temperature Units:

  • Temperature is measured in degrees Celsius (°C) or degrees Fahrenheit (°F).
  • Grade 5 students usually use Celsius (°C) in science class.

Common Temperature Benchmarks:

  • 0°C – Water freezes (very cold)
  • 20°C to 25°C – Room temperature (comfortable)
  • 37°C – Average human body temperature
  • 100°C – Water boils (very hot)

Real-Life Temperature Examples:

  • Ice cream: around -5°C
  • Refrigerator: around 4°C
  • Swimming pool on a warm day: around 25°C
  • Hot day outside: around 35°C
  • Oven baking cookies: around 180°C (not suitable for people!)

Clue Words Help:

  • “Cold,” “cool,” “warm,” and “hot” in the question give hints.
  • Example: “A hot summer day” – choose around 35°C not 10°C.

Compare and Eliminate:

  • If given two options (e.g., 5°C or 25°C for room temp), eliminate the one that doesn’t make sense.
  • Think about how that temperature would feel.

Use Common Sense:

  • A human body can’t be 90°C—too hot!
  • Ice cream can’t be 30°C—it would melt.

Learn with an example

📢 What is the temperature of a boiling pot of water? Choose the more reasonable answer.

  • 212°C
  • 100°C

100°C is a more reasonable answer. 212°C is too hot.

📢 What is the temperature of a cup of hot cocoa? Choose the more reasonable answer.

  • 60°C
  • 0°C

60°C is a more reasonable answer. 0°C is too cold.

📢 What is the temperature of boiling water? Choose the more reasonable answer.

  • 100°C
  • 100°C

100°C is a more reasonable answer. 212°C is too hot.
