Illustrate the reaction of an insoluble metal oxide with a dilute acid to produce crystals of a soluble salt in this class practical. Includes kit list and safety instructions.
-
ResourceProblem based practical activities
Discover how chemistry can relate to real world problems, so students can put their science knowledge into context.
-
ResourceInspirational chemistry book
This book contains experiments and resources which support the teaching of chemistry in schools. These range from new approaches to basic science (such as rates and rhubarb) to modern developments such as combinatorial chemistry and nanochemistry. All of the chapters are available for free on Learn Chemistry. Follow the links ...
-
ExperimentExtracting iodine from seaweed
Discover how ribbon seaweed (or kelp) can be used as a source of iodine in this demonstration or class experiment. Includes kit list and safety instructions.
-
ResourceUniversal indicators
This activity develops understanding of universal indicators and single indicators. The students build up their understanding by mixing two indicators. They also develop an awareness that the observed colour may be due to a mixture of colours.
-
ResourceWhat happens when things burn?
This resource presents chemists as real people and not stereotypical ‘mad scientists’ whose lives are completely dominated by science.
-
ExperimentDetergents, soaps and surface tension
A series of brief experiments on the effects of detergents and soaps on the surface tension of purified and hard water. Includes kit list and safety instructions.
