AQA practicals Physics Рvolume 

Details: 
Use appropriate apparatus to make and record the measurements needed to determine the densities of regular and irregular solid objects and liquids.
Volume should be determined from the dimensions of regularly shaped objects and by a displacement technique for irregularly shaped objects.
Dimensions to be measured using appropriate apparatus such as a ruler, micrometer or Vernier callipers.

Dimensions to be measured using appropriate apparatus such as a ruler, micrometer or Vernier callipers.

Skills:
Use appropriate apparatus to make and record measurements of length, area, mass and volume accurately. Use such measurements to determine the density of solid objects and liquids.
Use a variety of models such as representational, spatial, descriptive, computational and mathematical to solve problems, make predictions and to develop scientific explanations and understanding of familiar and unfamiliar facts.
Use scientific theories and explanations to develop hypotheses.
Plan experiments or devise procedures to make observations, produce or characterise a substance, test hypotheses, check data or explore phenomena.
Apply a knowledge of a range of techniques, instruments, apparatus, and materials to select those appropriate to the experiment.
Carry out experiments appropriately having due regard for the correct manipulation of apparatus, the accuracy of measurements and health and safety considerations.
Make and record observations and measurements using a range of apparatus and methods.
Evaluate methods and suggest possible improvements and further investigations.
Present observations and other data using appropriate methods.
Interpret observations and other data (presented in verbal, diagrammatic, graphical, symbolic or numerical form), including identifying patterns and trends, making inferences and drawing conclusions.
Communicate the scientific rationale for investigations, methods used, findings and reasoned conclusions through written and electronic reports and presentations using verbal, diagrammatic, graphical, numerical and symbolic forms.
Recognise the importance of scientific quantities and understand how they are determined.
Use SI units (eg kg, g, mg; km, m, mm; kJ, J) and IUPAC chemical nomenclature unless inappropriate.
Use an appropriate number of significant figures in calculation.
Use an appropriate number of significant figures.
Find arithmetic means.
Calculate areas of triangles and rectangles, surface areas and volumes of cubes.
