Match to the definition 0 Overview Using this Resource Connecting to the Curriculum Marking Student Responses Further Resources This task is about matching chemical terms to their definitions. Chemical substances can be classified as elements, compound, or mixtures. Select the correct definition for each term. Question a) Select the correct definition for the term 'element'. contains only 1 atom contains 2 or more types of atoms but they are not strongly bonded together contains 2 or more types of atoms bonded together contains only 1 type of atom Question b) Select the correct definition for the term 'compound'. contains only 1 atom contains 2 or more types of atoms but they are not strongly bonded together contains 2 or more types of atoms bonded together contains only 1 type of atom Question c) Select the correct definition for the term 'mixture'. contains only 1 atom contains 2 or more types of atoms but they are not strongly bonded together contains 2 or more types of atoms bonded together contains only 1 type of atom Task administration: This task can be completed with pencil and paper or online with auto-marking. Level: 5 Curriculum info: Science, Investigating in science, Material World Keywords: structure of matter, elements, compounds, mixtures, atoms, vocabulary Description of task: Students select the correct written definition of the words element, compound, and mixture. Curriculum Links: Science capabilities The capabilities focus is brought about by the conversations you have and the questions you ask. Capability: Interpret representations This resource provides opportunities to identify how symbols are used to represent the structure of elements, mixtures and compounds.
