List safety precautions for experiments. Draw the arrangement of equipment for a described experiment using correct conventions. Identify variables that need to be controlled in an investigation (and describe how that could be done). Identify the independent and dependant variables in an investigation. Give the units of measurements used in investigations. Describe how to safely use equipment used in investigations. Identify safety issues that occur in laboratory and describe ways to minimise risks. Assess the method used in an investigation and identify improvements to the method. Summarise data from investigations and secondary sources. Represent data, including graphs, keys, models, diagrams, tables. Extract information from diagrams, flowcharts, tables, databases, other texts, graphs including histograms and column, sector and line graphs. Apply simple numerical procedures, eg calculating means/averages when processing data and information. Check the reliability of gathered data and information by comparing with observations or information from other sources. Construct and use a range of representations, including graphs, keys and models to represent and analyse patterns or relationships. Identify data which supports or discounts a question being investigated or a proposed solution to a problem. Propose inferences based on presented information and observations. Present ideas, findings and solutions to problems using scientific language. Use appropriate text types in presentations, including a discussion, explanation and procedures. Construct and use the appropriate type of graph (histogram, column, sector or line graph) to express relationships clearly and succinctly. Identify questions and problems that can be investigated scientifically. Make predictions based on scientific knowledge and your observations. Chemical World Describe the behaviour of matter in terms of particles that are continuously moving and interacting. Relate an increase or decrease in the amount of heat energy possessed by particles to changes in particles movement. Use a simple particle model to predict the effect of adding or removing heat on different states of matter. Relate changes in the physical properties of matter to heat energy and particle movement that occur during evaporation, condensation, boiling, melting and freezing. Explain density in terms of a simple particle model. Identify the benefits and limitations of using models to explain the properties of solids, liquids and gases. Outline what is meant by the terms ‘pure substance’, ‘impure substance’ and ‘mixture’. Identify that impure substances are always mixtures. Distinguish between pure substances and impure substances, providing everyday examples of each. Outline what is meant by the terms solvent, solute, solution, aqueous, soluble, insoluble. Apply the terms solvent, solute and solution to a number of everyday examples of mixtures. Distinguish between the terms soluble and insoluble. Identify examples of everyday substances that are soluble and insoluble. Outline examples of the importance of water as a solvent in everyday life, industry and the environment. Identify that the techniques of decantation and filtration are used to separate substances. Describe the techniques. Identify the physical principle involved in both techniques and examples of where they are used. Define and use correctly, the terms filtrate and residue to describe the components of the mixture separated in filtration. Outline how filtration and decanting are used to prepare yams for eating. Outline how filtration and decantation are used at a water filtration plant. Identify how evaporation is used to separate substances (include the principles of separation). Describe the technique and examples of where it is used in everyday life and industry. Identify that crystallisation is used to separate a soluble substance from a liquid where the solvent has a much lower boiling point of the components of the mixture – give an example. Describe the technique of crystallisation and examples of where it is used. Describe the application of distillation and the physical property basis of the technique. Describe the technique of distillation, using terms distillate, residue, evaporation, condensation and condenser appropriately. Label a diagram of the distillation apparatus. Identify that chromatography is used to separate a mixture of soluble substances from one another where the substances each have a different solubility in a particular solvent. Give examples of where chromatography is used. Justify why blood is classified as a mixture. identify the major components of blood. Living World Identify the reasons for classifying living things. Classify a variety of living things based on similarities and differences in structural features. Use keys to identify a range of plants and animals. (branched and written keys). Identify examples of groups of different microorganisms. Outline the structural features used to group living things, including plants, fungi, animals and bacteria. Give examples of features of plants and animals that are adaptations for survival and reproduction in their environment. Identify that living things are made of cells. Identify structures within cells, including the nucleus, cytoplasm, cell membrane, cell wall and chloroplast and describe their functions. Draw and label a plant and animal cell and distinguish between the two. Outline the role of respiration in providing energy for all activities of the cell. Identify that new cells are produced by cell division – describe the process of binary fission. Distinguish between unicellular and multicellular organisms. Identify the structures that comprise the organisation of multicellular organisms and how they are dependant on each other. Read more
