This activity is fairly synoptic in nature and should encourage a rapid consideration of the range of concepts met in chemistry taught to ages 11–13.

Chemistry for the gifted and talented: odd one out
Level
Specification
- Northern Ireland
- GCSE
- CCEA Chemistry
- Unit 1: Structures, Trends, Chemical Reactions, Quantitative Chemistry and Analysis
- 1.9 Chemical analysis
- 1.9.1 demonstrate knowledge and understanding that a pure substance is a single element or compound not mixed with any other substance; and
- 1.9.2 demonstrate knowledge and understanding that pure elements and compounds melt and boil at specific temperatures and melting point and boiling point can be used to distinguish pure substances from mixtures.
- 1.9.4 demonstrate knowledge and understanding of the terms soluble, insoluble, solute, solvent, solution, residue, filtrate, distillate, miscible, immiscible, evaporation and condensation;
- 1.9.6 describe paper chromatography as the separation of mixtures of soluble substances by running a solvent (mobile phase) through the mixture on the paper (stationary phase), which causes the substances to move at different rates over the paper;
