🎓 Learning Guide: Reading Thermometers

Learning focus: Read a displayed thermometer carefully by identifying its scale marks, units and indicated temperature.

Science — Thermometer Reading Temperature-scale reading practice

Learning objectives

Identify scale units and the spacing between labelled marks
Determine the liquid-column or pointer position relative to the nearest divisions
Explain the reading instead of guessing from visual height alone

Concepts and principles

Temperature is a measurement and must be expressed with a unit and scale.
If a scale interval spans equally spaced divisions, each division represents the same increment.
A drawing is not a clinical thermometer unless its design and measurement purpose establish that.

Examples and worked solutions

Independent teaching example (not verified as an in-game prompt): An illustrative scale marks 20 °C and 30 °C ten equal divisions apart. What does each division represent?: Worked solution: Each division represents (30−20)/10=1 °C. A reading four divisions above 20 °C is 24 °C.

Try this activity

Identify the actual labelled units on the displayed thermometer
Count the number of small divisions between neighbouring labelled values
Make a reading and compare with the game feedback

Expected observations and explanations

Ignoring a missing unit can change the meaning of a value.
Equally spaced marks allow interpolation if the artwork uses a linear scale.

Assessment questions and answers

Why count the divisions before reading?: Answer: The smallest increment depends on the printed scale.
If a reading is midway between 10 °C and 20 °C on a uniform scale, what is it?: Answer: 15 °C.
