Quantitative chemistry

Classroom resources featuring activities from our Quantitative Chemistry professional development 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. 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.

Astounding numbers

This activity is designed to be fun and generate a wow factor for the students. It tries to convey how amazing the scale is that we use in chemistry. In question 8 the students are asked to use creative thinking and come up with some questions of their own.

The change in mass when magnesium burns

In association with

A class practical to measure the change in mass when magnesium burns and to find the formula of magnesium oxide. Includes kit list and safety instructions.

Hydrated copper sulfate crystals (blue in colour)

Finding the formula of hydrated copper(II) sulfate

In association with

In this experiment students will measure the mass of hydrated copper(II) sulfate before and after heating and use mole calculations to find the formula.

Balloon filling syringe with gas

Determining relative molecular masses by weighing gases

In association with

Demonstrate how different gases can be weighed in a gas syringe and their relative molecular masses determined using the ideal gas equation.

The volume of 1 mole of hydrogen gas

Calculate the volume of one mole of hydrogen at room temperature and pressure by  reacting magnesium with hydrochloric acid

Magnesium flakes

Gas volume

Construct apparatus to measure the molar volume of hydrogen produced from the reaction of magnesium with vinegar.

A microscale acid-base titration

In association with

In this experiment you will be using microscale titration apparatus to complete an acid-base neutralisation. The aim is to calculate the exact concentration of sodium hydroxide solution.

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.

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.
