This collection of classroom resources features activities from our Energy and change course for teachers, from our Teaching Chemistry series. This collection is most valuable to those who have attended this course and wish to put into practice with their students some of the ideas and activities presented as part of that event. Please note that this list is not exhaustive; not all trainer activities have a corresponding classroom resource. In some circumstances there is variation between the training resource and classroom resource.
A mixture of alcohol and air in a large polycarbonate bottle is ignited. The resulting rapid combustion reaction, often accompanied by a dramatic ‘whoosh’ sound and flames, demonstrates the large amount of energy released in the combustion of alcohols.
The context of a fat-pan (chip-pan) catching fire is used to demonstrate the conditions required to start combustion, and how to put such a fire out safely.
A video and teacher notes demonstrating the dangers of adding water to a fat fire.
Surprise your students by soaking a piece of paper (or an old £5 or £10 note) in a mixture of ethanol and water and igniting it. Watch as the ethanol burns… but the paper does not.
In this demonstration experiment, a mixture of glycerol (propane-1,2,3-triol) and potassium manganate(VII) crystals bursts into flame, giving off clouds of steam, after a short time lag.
Observe an endothermic reaction as solid hydrated barium hydroxide is mixed with solid ammonium chloride to produce a liquid that evolves into ammonia gas. The temperature drops dramatically to about -20 °C.
Some reactions give out heat and others take in heat. In exothermic reactions the temperature goes up, in endothermic reactions the temperature goes down. In this experiment, various reactions are examined. Temperatures are measured to decide whether a particular reaction is exothermic or endothermic.
Students carry out test-tube reactions and detect whether the process gives out or takes in energy (exothermic or endothermic reaction).
Students add powdered metals to a copper(II) sulfate solution and measure the temperature rises.
Probe your students’ understanding of this fundamental concept and reflect on your demonstrations with our practical tips
This experiment compares the amounts of heat energy produced by burning various alcohols.
