How to use and develop models – pupil resources

This collection of classroom resources features all the pupil activities from our Developing expertise in teaching how to use and develop models 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.


Resources

Elements, compounds and mixtures

Chemistry is a conceptual subject and, in order to explain many of these concepts, teachers use models to describe and explain the microscopic world and relate it to the macroscopic properties of matter. This resource is designed to provide strategies for dealing with some of the misconceptions that students have ...

Mass and dissolving

Chemistry is a conceptual subject and, in order to explain many of these concepts, teachers use models to describe and explain the microscopic world and relate it to the macroscopic properties of matter.

Ionic Su Doku

This activity gives students practice at working out formulae in a problem solving context.

Image

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.

Image

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.

Image

Diffusion of gases – a safer alternative to bromine

Demonstration of the diffusion of gases.

Image

Diffusion in liquids

In association with

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.

Image

The fractional distillation of crude oil

In association with

This experiment simulates the industrial fractional distillation of crude oil in the laboratory.

Image

Heating Group 1 metals in air and in chlorine

In association with

This is a demonstration that shows the reactions of Group 1 metals in air and in chlorine.  It does not clearly show the trends in reactivity of Group 1 metals, which are better demonstrated by the reactions in water, which follow on well from this demonstration.

Image

Bonding models

This activity gets the students to think of the model they have been taught as a model rather than the truth.

Changes in chemistry

Chemistry is a conceptual subject and, in order to explain many of these concepts, teachers use models to describe and explain the microscopic world and relate it to the macroscopic properties of matter. This resource is designed to provide strategies for dealing with some of the misconceptions that students have ...
