This video shows a classroom experiment to demonstrate that hot air rises. Many weather systems, including land and sea breeze and hurricanes, are the result of hot air rising. To illustrate, Dr Sylvia Knight shows you a simple practical demonstration using a teabag, matches and a heatproof tile that you can try for yourself. Ideal for Geography Key stage 3. If you’d like to complete this experiment, please be aware of the potential fire risk and take care when using the matches. We recommend you complete the experiment well away from flammable materials, within a room with a high ceiling.

This video shows how to use an infrared thermometer to measure temperature, in the air and of clouds and to demonstrate the presence of greenhouse gas molecules. Ideal to support Geography Key stage 3. This video follows on from our video - Measuring The Weather In this video, Dr Sylvia Knight demonstrates how to use a range of thermometers to measure the temperature of the ground, the atmosphere and even to show the greenhouse effect. After viewing this video you could investigate the microclimate of your school; temperature differences will show up best on a calm day.

This video shows classroom experiment to measure wind speed and direction using bubbles, and explains that this is as an example of flow visualisation. Ideal to support Geography Key stage 3. Measuring the speed and direction of the wind is one of many practical ways you can investigate the weather in your surroundings. In this video, Janet Barlow, Professor of Environmental Physics in the Department of Meteorology demonstrates how you can measure the speed and direction of the wind using a bubble machine. Fieldwork ideas after viewing this video: Use bubbles to see if you can estimate the wind speed by timing how long they take to travel 5m (roughly 5 large paces) Find a building you can walk all the way round and which doesn’t have too much vegetation around it. On a windy day, walk around the building blowing bubbles, and see how the speed and direction of the bubbles changes. You could even try and show it on a sketch map. Are there places where the bubbles get caught in turbulence, going round and round in circles?
