Classroom resources featuring activities from our Practical chemistry for NQTs professional development course for teachers
This collection of classroom resources features activities from our Practical chemistry for NQTs 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.
Observe the diffusion of the gases ammonia and chlorine, and their relative rates as a function of molecular weight
The nature of science resources try to give students an awareness of science as a changing body of knowledge. This resource contains activities for students which help them understand the difference between observation and inference, and how to interpret patterns.
Prove that two solids can react together by using white lead nitrate and white potassium iodide to make yellow lead iodide.
How to bridge the gap between the ‘seen’ science and the ‘unseen’ explanation
This resource presents chemists as real people and not stereotypical ‘mad scientists’ whose lives are completely dominated by science.
Place concentrated ammonia solution on a pad in one end of a tube and concentrated hydrochloric acid on a pad at the other and watch as the two gases diffuse far enough to meet and form a ring of solid ammonium chloride.
Demonstrate the diffusion that takes place in liquids using colourless crystals of lead nitrate and potassium iodide at opposite sides of a petri dish of deionised water.
Gases give rise to particular hazards so great care must be taken when preparing, collecting or testing.
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.
A strong plastic bottle is filled with a 2:1 ratio of oxygen to methane and the mixture ignited with the bottle standing on a suitable ‘launch pad’. The mixture ignites with a loud bang and the bottle flies several metres.
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.
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.
This experiment involves the reaction of a metal with the oxide of another metal. When reactions like these occur, the two metals compete for the oxygen. The more reactive metal finishes up with the oxygen (as a metal oxide). If the more reactive metal starts as the oxide then no ...
Prove that aluminium is a more reactive metal than iron by demonstrating the highly exothermic reaction between aluminium and iron(III) oxide resulting in molten iron.
Students reduce iron(III) oxide with carbon on a match head to produce iron in this small scale example of metal extraction. The experiment can be used to highlight aspects of the reactivity series.
Model the industrial process of cracking larger hydrocarbons to produce smaller alkanes that can be converted into petrol.
Produce a small explosion in your classroom by electrolysing water then re-combining the hydrogen and oxygen gas.
This activity is most appropriate for students aged 14-16 to illustrate chemical reactions and useful materials made from rocks.
The background and chemistry of burning calcium with hydrogen and oxygen to make ‘limelight’.
Create a ‘rainbow’ effect in a glass tube using universal indicator solution, hydrochloric acid and sodium hydroxide.
Drops of dilute acid and alkali are placed a few centimetres apart on a sheet of filter paper and allowed to spread out until they meet. A few drops of Universal indicator are then placed over the moist area of the filter paper and a band of colours showing the ...
Sublimation is an interesting physical change. When a substance sublimes, it changes directly from a solid to a gas without passing through the liquid state. Dry ice sublimes, as do iodine and mothballs. This experiment involves the study of another common substance that sublimes – air freshener.
