Teaching activities
Introduction
Write on the board the words: freezing, cold, warm, hot and boiling. Draw a vertical scale from cold to hot next to the words, and ask children to order the words on the scale. Explain that these words describe the temperature of a place. Ask for examples of places where they think the temperature is freezing, cold, warm, hot and boiling.
Activities
Show the display of the thermometer. Explain that a thermometer is used to measure the temperature precisely in degrees Centigrade. Show a real thermometer, and then model on the scale on the board how the liquid rises up in the tube as the temperature gets hotter.
Explain that to use a thermometer accurately, they have to read the scale on the side of the thermometer. What are the hottest and coldest temperatures this thermometer can read? Ensure that children use the measure degrees centigrade. What intervals is the scale marked in? What temperature is it currently showing?
Put the children into small groups and give each group a thermometer, a diagram of a thermometer, three beakers of water (cold, warm and hot), and a table to record results. Ask children to a) measure the temperature of the water in each beaker, b) record the temperatures in the table, and c) mark the temperatures on the thermometer diagram.
Plenary
Ask one group for their results. Mark the three temperatures on the display thermometer. Tell the children the outdoor air temperature today. Explain that in weather reports and forecasts, we are told the outdoor air temperature so we know how hot or cold a place is. Display the list of temperatures for different places in the world from newspaper or internet weather reports. For each place, ask the children if they were going there on holiday would they pack t-shirts or jumpers? Is the temperature hotter or colder than here?
