Pedagogical approaches – pupil resources

This collection of classroom resources features all the pupil activities from our Developing expertise in teaching pedagogical approaches course for teachers. 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.


Ocean wave

Chemistry of the oceans

A booklet aimed at students aged between 14 and 16 years. The text is supported by questions, tables of data and diagrams.

Addition polymerisation

In association with

Alkenes (carbon compounds containing double bonds) undergo addition reactions. In this experiment molecules of phenylethene (styrene) – the monomer – add on to each other to form polyphenylethene (polystyrene) - the polymer.

Polymer puzzles

This activity is designed to develop the students’ higher order thinking – particularly critical thinking skills – in the context of problem solving. It should help students to recall the facts about some common polymers.

Extracting metals from rocks

In association with

This experiment involves producing copper from copper ore (malachite). The composition of malachite is mainly copper(II) carbonate CuCO3.Cu(OH)2. This experiment involves heating the copper(II) carbonate with carbon.

Chemicals from seawater

In association with

Seawater is often called salt water but it contains various different salts. In this experiment you will separate some of these salts from the mixture.

Making plastic from potato starch

In association with

In this activity students make a plastic from potato starch and investigate the effect of adding a ‘plasticiser’ has on the polymer that they make.

Nylon thread

Making nylon: the ‘nylon rope trick’

Perform this ‘trick’ with a solution of decanedioyl dichloride in cyclohexane floated on an aqueous solution of 1,6-diaminohexane. As nylon forms at the interface, it can be pulled out as fast as it is produced forming a long thread: the ‘nylon rope’.

One pence pieces

Turning copper coins into 'silver' and 'gold'

In association with

Perform something close to alchemy by dipping a ‘copper’ coin into a solution of sodium zincate in contact with zinc to make it appear silver, before holding it in a Bunsen flame for a few seconds to form an alloy of brass making it appear gold.

Copper solution soaked splint in Bunsen burner flame.

Flame colours: a demonstration

In association with

Show the flame colours of alkali metals, alkaline earth metals, and other metal salts by safely spraying sodium chloride, potassium chloride, lithium chloride, copper sulfate and ethanol through a bunsen flame.
