Lesson Details
Key learning points
- Thermometers measure temperature in degrees Celsius (ºC).
- Glass thermometers are fragile and need to be handled with care.
- To accurately read the scale on a glass thermometer, your eye needs to be level with the top of the coloured liquid.
- Pure ice melts at 0ºC and pure water boils at 100ºC.
- If left for long enough, all objects in a room will reach the same temperature.
Common misconception
Pupils often estimate the temperature of an object based on its materials, rather than the temperature of the surroundings.
Measure the temperature of several things that are all at room temperature such as water, sand and the air, in order to show that they are all the same.
