Year 7 Science



What are we learning 




  • Explain the properties of the different states of matter (solid, liquid and gas) in terms of the particle model, including gas pressure 
  • Explain changes of state in terms of the particle model. 
  • Know that conservation of mass applies to changes of state 
  • Define the concept of a pure substance 
  • Describe what is meant by mixtures, including dissolving 
  • Explain diffusion in terms of the particle model 
  • Describe simple techniques for separating mixtures: filtration, evaporation, distillation and chromatography 
  • Identify pure substances. 
  • Describe energy changes on changes of state 
  • Use and interpret negative numbers 
  • Plot graphs of secondary data 
  • Make and record accurate measurements 
  • Check for reproducibility and recognise when results are reproducible 
  • Evaluate separation methods and suggest improvements 
  • Identify hazards and risks and suggest appropriate safety precaution 
  • Identify anomalies and leave them out of lines of best fit 


Cells, tissues and organs 

  • Know cells as the fundamental unit of living organisms, including how to observe, interpret and record cell structure using a light microscope 
  • Know the functions of the cell wall, cell membrane, cytoplasm, nucleus, vacuole, mitochondria and chloroplasts 
  • Identify the similarities and differences between plant and animal cells 
  • Describe the role of diffusion in the movement of materials in and between cells 
  • Describe the hierarchical organisation of multicellular organisms: from cells to tissues to organs to systems to organisms. 
  • Identify the structural adaptations of some unicellular organisms 
  • Know the tissues and organs of the human digestive system, including adaptations to function and how the digestive system digests food 
  • Know the structure and functions of the gas exchange system in humans 
  • Correctly use a microscope to view samples in greater detail 
  • Calculate magnification using eyepiece lens x objective lens 
  • Use magnification = image size ÷ actual size 
  • Identify independent, dependent and control variables 
  • Draw a suitable results table 
  • Carry out an investigation to test a hypothesis 
  • Calculate means and rounding up numbers appropriately 
  • Plot graphs with line of best fit 
  • Use data to form conclusions 



  • Know processes that involve energy transfer: changing motion, dropping an object, completing an electrical circuit, stretching a spring, metabolism of food, burning fuels. 
  • Explain heating and thermal equilibrium: temperature difference between two objects leading to energy transfer from the hotter to the cooler one, through contact (conduction), movement of fluids (convection) or radiation; such transfers tending to reduce the temperature difference: use of insulators 
  • Understand energy as a quantity that can be quantified and calculated; the total energy has the same value before and after a change 
  • Compare the starting and the final conditions of a system and describing increases and decreases in the amounts of energy associated with movements, temperatures, changes in positions in a field, in elastic distortions and in chemical compositions 
  • Compare energy values of different foods (from labels) (kJ) 
  • Comparing power ratings of appliances in watts (W, kW) 
  • Compare amounts of energy transferred (J, kJ, kW hour) 
  • Understand domestic fuel bills, fuel use and costs 
  • Describe fuels and energy resources. 
  • Understand electric current as a flow of charge, measured in amperes, in circuits, series and parallel circuits, currents add where branches meet and current as flow of charge 
  • Understand potential difference, measured in volts, battery and bulb ratings 
  • Identify variables to change, measure and control 
  • Identify hazards and risks, and suggest appropriate and relevant safety precautions 
  • Describing patterns in primary and secondary data 
  • Drawing graphs 
  • Evaluate methods and data, making suggestions for improvements to procedures or equipment 


Reproduction and variation 

  • Describe reproduction in humans (as an example of a mammal), including the structure and function of the male and female reproductive systems, menstrual cycle (without details of hormones), gametes, fertilisation, gestation and birth 
  • Describe reproduction in plants, including flower structure, wind and insect pollination, fertilisation, seed and fruit formation and dispersal, including quantitative investigation of some dispersal mechanisms. 
  • Describe differences between species 
  • Describe the variation between individuals within a species being continuous or discrete (discontinuous), to include measurement and graphical representation of variation 
  • Analyse secondary data, describing patterns, suggesting reasons for patterns, spotting anomalies 
  • Collect, process and display data appropriately, explaining the choice for bar charts or line graphs in terms of the type of data 
  • Identify variables 
  • Use a model to illustrate sexual reproduction 


Chemical Reactions 

  • Understand conservation of mass in chemical reactions. 
  • Understand chemical reactions as the rearrangement of atoms 
  • Use word equations to represent chemical reactions 
  • Define acids and alkalis in terms of neutralisation reactions 
  • Use indicators and the pH scale to measure acidity/alkalinity 
  • Know acids react with metals to produce a salt and hydrogen 
  • Know acids react with alkalis to produce a salt plus water 
  • Make observations for evidence of a reaction 
  • Recognise hazard symbols, suggest risks associated with them and appropriate safety precautions 
  • Identifying variables to change, measure and control to test a hypothesis 
  • Recognising repeatable data and processing it appropriately 
  • Choice of bar chart based on categoric data 
  • Check for and comment on reproducibility

  • Write conclusions based on results obtained or secondary data provided, and relate results to predictions/ hypothesis 
  • Use and rearrange equations to perform calculations, using SI units where appropriate.
