3.6 Temperature

• Temperature conditions: cold, warm and hot
• Comparing temperature: hotter, warmer, colder and same as
• Units of temperature: degrees Celsius (°C) and Kelvin (K)
• Converting degrees Celsius to Kelvin and Kelvin to degrees Celsius
• Working out temperature in °C and K in real-life situations
• Reading temperature of places with IT or other resources; temperature change in the environment

• describe the temperature conditions of the immediate environment as either warm, hot or cold
• compare temperature using hotter, warmer, colder and same as in different situations
• identify units of measuring temperature as degrees Celsius and Kelvin in different situations
• convert units of measuring temperature from degree Celsius to Kelvin and vice-versa
• work out temperature in degrees Celsius and Kelvin in real-life situations
• use IT devices or other resources to read temperature conditions of different places
• recognise temperature changes in the environment

1. Cold, warm and hot
   40 min · 1 practice tasks · quiz
   Describe the immediate environment as cold, warm or hot from observation, without yet using a numbered scale.
2. Hotter, warmer, colder, same as
   40 min · 1 practice tasks · quiz
   Compare two temperatures using hotter, warmer, colder and same as, including Kenyan places and safe touch tests.
3. Celsius and Kelvin
   40 min · 1 practice tasks · quiz
   Identify degrees Celsius and Kelvin as units of temperature, read a Celsius thermometer, and meet ice, body and steam points.
4. Converting Celsius and Kelvin
   40 min · 1 practice tasks · quiz
   Convert °C to K by adding 273 and K to °C by subtracting 273, including a short conversion table.
5. Working out temperatures
   40 min · 1 practice tasks · quiz
   Work out rises, falls and differences in °C and K, including body temperature and a freezer below zero.
6. Temperatures of places
   40 min · 1 practice tasks · quiz
   Read temperatures of Kenyan places from IT or a bulletin, convert if needed, and recognise change through the day and across regions.
