Aim • To estimate and measure temperature in degrees Celsius. Success Criteria • I can use language related to temperature. • I can estimate temperature in degrees Celsius. • I can measure temperature in ˚C using a thermometer.

Temperature Adjectives There are lots of words that can be used to describe the temperature. Can you order these temperature adjectives from coldest to warmest? Click to see if your order was correct. boiling boiling lukewarm hot freezing warm lukewarm chilly warm chilly cold hot freezing cold

Degrees Celsius Temperature is a measure of heat. Temperature tells us how hot or cold something is. Thermometers are used to measure temperature. We usually measure temperature in degrees Celsius (˚C) but some parts of the world use degrees Fahrenheit (˚F).

Degrees Celsius The Celsius scale is based on the freezing point of water being 0 degrees and the boiling point being 100 degrees. 100 90 80 70 60 50 40 30 20 10 0

Degrees Celsius We can measure the temperature of air, liquids or objects using a thermometer . 100 90 80 70 Most thermometers have small tubes and 60 a bulb of liquid at the bottom. The hotter 50 the temperature, the higher the liquid 40 from the bulb rises in the tube. There are 30 markings along the side of the glass tube 20 10 that shows the temperature. 0
