AQA 9-1 Topic 2 Bonding - Polymers and states of matter (including changes of state)

A lesson explaining the structure of polymers and properties of polymers, including a step-by-step method on drawing repeating units and explanation of the properties of thermosoftening and thermosetting polymers. The lesson also includes an explanation of the properties of solids, liquids and gases and a step-by-step method on how to predict the state of a substance when given the melting and boiling point.

The lesson features:

• A starter consisting of 10 basic recall questions from previous learning with animated answers (ionic formula and properties of ionic compounds, covalent bonding diagrams, properties of simple covalent substances and graphite, properties of metals and alloys)
• Slides introducing what a polymer is and how to draw repeating units
• Practice questions on drawing repeating units with animated answers
• A paired teaching activity on the difference between thermosoftening and thermosetting polymers
• A discussion task to illicit prior knowledge on solids, liquids and gases
• A summary table explaining the properties of solids, liquids and gases
• Slides explaining how to predict the state of substances using number lines with two animated examples
• Summary questions asking students to predict the state of substances using a data table containing melting and boiling points
