AQA practicals Physics – specific heat capacity 

An investigation to determine the specific heat capacity of one or more materials.
The investigation will involve linking the decrease of one energy store (or work done) to the increase in temperature and subsequent increase in thermal energy stored.

Use appropriate apparatus to make and record measurements of mass, time and temperature accurately.
Use, in a safe manner, appropriate apparatus to measure energy changes/transfers and associated values such as work done.

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.
Translate data from one form to another.
Carry out and represent mathematical and statistical analysis.
Represent the distribution of results and make estimations of uncertainty.
Interpret observations and other data (presented in verbal, diagrammatic, graphical, symbolic or numerical form), including identifying patterns and trends, making inferences and drawing conclusions.
Present reasoned explanations including relating data to hypotheses.
Be objective, evaluate data in terms of accuracy, precision, repeatability and reproducibility and identify potential sources of random and systematic error.
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.
Change the subject of an equation.
Substitute numerical values into algebraic equations using appropriate units for physical quantities.
