When is it happening  Year 7 Term 1 
What will students learn  Know about the arrangement and movement of particles in different states. Describe and identify the processes involved during changes of state and explain properties and changes of state using a particle diagram. Students must be able to define: particle, particle model, diffusion, gas pressure, density, evaporation, boil, condense, melt freeze and sublime. Students must also know what a pure substance is and how to identify it. Examples of mixtures and ways to separate them using their physical properties. Students must also know the definitions of: Solvent, solute, dissolve, solution, soluble, insoluble, solubility, pure substance, mixture, filtration, distillation, evaporation and chromatography.
Key Knowledge that students should know at the end of 'Topic' This is the knowledge that students will meet for the first time in this topic  The three states of matter and the processes of changing states. The water cycle. How particles are arranged within the particle model. Diffusion of gases and liquids. They will also learn about exceptions and limitations to the accepted model. How to present and use data. How to draw the particle model. Students will learn how to separate mixtures using a range of techniques. They will also learn how to identify a pure/impure substance using data. How to identify unknown samples using chromatography. Students will use graph skills to plot and analyse solubility of salt/sugar.
This is knowledge that students may have met before but will need to deepen their understanding  Students should already be able to identify solids, liquids or gases, name some examples and describe some of their properties. Students may have experience of simple separation techniques such as filtration. They will have knowledge of melting, freezing and boiling.
Key Skills that students should be able to demonstrate at the end of 'Topic' This is the skills  that students will meet for the first time in this topic Accurate diagram for the particle model. Use scientific equipment to separate mixtures; including Evaporation, distillation and chromatography.
This is skills that students may have met before but will need to develop  Students may not have done practical investigations using scientific equipment in KS2. Lab safety, bunsen burner skills. How to analyse a chromatogram.
Key vocabulary that students should know and understand

Particle, particle model, water cycle, diffusion, gas pressure, pure, density, evaporation, condense, sublime, solvent, solute, dissolve.
