Examples of use Organise the words and statements: into your own groups. into “agree”, “disagree”, “it depends…” categories. to complete a sentence (e.g. “all living things…”) into true or false categories. into a hierarchy of importance.

Tips Include common misconceptions and areas of common difficulty. Groups should be asked to justify their decisions. Areas of difficult or disagreement can be explored further.

Can be used to detect the presence of specific elements in a sample. Is produced when electromagnetic radiation is given off by a substance. Can be used to detect the presence of specific elements in a sample. Electrons are in their ground state and move to an excited state. Electrons are in an excited state and move to their ground state. The sample to be investigated is in the gaseous state. Is produced when white light is passed through a substance. Can be used to detect the concentration of a chemical substance in a sample. The substance to be investigated is excited by an electric current or heat. The spectra are usually in the UV and visible sections of the E.M. spectrum. Involves transitions of electrons between shells and sub-shells in atoms. Spectra are coloured lines on a dark background. Spectra are dark lines on a coloured background. Used to detect the presence of specific elements by reference to a database of “fingerprints”. Requires a calibration curve.
