Class experimentReacting copper(II) oxide with sulfuric acid
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
A collection of resources, aligned with GCSE bodies, to support learners in England, Wales, and N Ireland.
-
DemonstrationExtracting 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.
-
Class 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.
-
ResourceWhich sodium salt is which?
How does sodium interact with other chemicals, and how can you identify them? Includes kit list and safety instructions.
-
ResourceWhich gas is which?
Five mystery gases, and a problem to solve. Students must identify each gas, and do so quickly. Includes kit list and safety instructions.
-
ResourceWhat makes the candle go out?
Why do candles go out, how do different candles react in the same environment, and can we figure out why they’re different? Includes kit list and safety instructions.
-
ResourceWhat is honey made of? The optical rotation of sugars
Discover more about carbohydrates, chirality, optical rotation, in honey. Includes kit list and safety instructions.
