Mixture - a combination of two or more pure substances that can be easily separated again, Pure substance - is made up of only one type of substance that cannot be further separated by physical means, Solution - when a substance dissolves in another, forming a clear mixture, Solute - is the substance being dissolved., Solvent - is the substance that is dissolving the solute., Solubility - is the degree to which the solute will dissolve., Soluble - where a large amount of solute will dissolve, Lightly soluble - where a small amount of solute will dissolve, Insoluble - where only an extremely small amount of solute will dissolve, Separation in chemistry means - the removal of substances from a mixture of two or more substances, Handpicking as a separation technique - involves separating large sized particles manually. This is generally carried out when particles are large and easily distinguished from one another., Magnetism as a separation technique - involves separating materials that contain iron and steel using a magnet , Filtration as a separation technique - involves separating insoluble solids from a liquid using filter paper and a funnel., Evaporation as a separation technique - involves separating a soluble solid from a liquid using a Bunsen burner., A hypothesis - is a clear, brief statement of what you expect to observe during the experiment, A risk assessment - Identifies any risks you may face while conducting the experiment, A materials list - is a list of all the materials and equipment required to conduct the experiment. This includes quantities and measurements., Initial quantity - is the amount of pure substance that went into the mixture., Reclaimed quantity - is how much of the pure substance was separated successfully from the mixture., Material properties - are the scientific describers of a pure substance, i.e is a liquid, is transparent etc., Observations - are short notes taken by the scribe about what the group can see, hear or smell during the experiment., Experiment summary - is a written paragraph that recounts your groups experiment combining information from the experiment aim, group observations and results., Experiment evaluation - is a paragraph that discusses specific improvements required to improve the overall success of the experiment.,
