Practical chemistry for NQTs

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.

Develop deeper understanding with models

How to bridge the gap between the ‘seen’ science and the ‘unseen’ explanation

An image showing a teacher surrounded by students, sitting inside a structure that resembles the structure of a 5-membered ring

How to teach scientific models

Be explicit when explaining models and their purpose

An image showing a male teacher holding a piece of paper with the structure of methane on it, a methane ball and stick molecular model, and thinking about an alternative model view; the blackboard behind shows the chemical formula of methane

The atom detectives

This resource presents chemists as real people and not stereotypical ‘mad scientists’ whose lives are completely dominated by science.

Ammonia tank

Diffusion of gases: ammonia and hydrogen chloride

In association with

Generating, collecting and testing gases

In association with

Read our standard guidance on generating, collecting and testing gases during practical experiments, including carbon dioxide, hydrogen, oxygen and chlorine.

Large plastic water bottle required for whoosh bottle demonstration.

The ‘whoosh’ bottle demonstration

In association with

This exciting demonstration is a combustion reaction where a mixture of alcohol and air in a large bottle is ignited. Includes kit list and safety instructions.

Image

The methane rocket

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.

Endothermic solid–solid reactions

In association with

Observe an endothermic reaction between two solids in this demonstration or class experiment. Includes kit list and safety instructions.

A purple-red flame against a black background

A spontaneous exothermic reaction

In association with

Illustrate the reaction between glycerol and potassium manganate(VII) to produce flames and steam in this demonstration. Includes kit list and safety instructions.

Competition for oxygen

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 ...

A photograph showing a highly exothermic thermite explosion against a black background

The thermite reaction between aluminium and iron(III) oxide

In association with

Illustrate a highly exothermic thermite reaction resulting in molten iron in this teacher demonstration. Includes kit list and safety instructions.

A macro photograph of the head of an unlit matchstick

Extraction of iron on a match head

In association with

Try this practical as a small scale example of metal extraction, reducing iron(III) oxide with carbon on a match head. Includes kit list and safety instructions.

A photograph showing the outside of an industrial furnace and heat exchanger, used in the cracking of hydrocarbons

Cracking hydrocarbons in liquid paraffin with a catalyst

In association with

Model the industrial process of cracking larger hydrocarbons to produce smaller alkanes in this demonstration or class practical. Includes kit list and safety instructions.
