Use laptops to research the accepted value for the metal you plan to use. Research several sources and quote the values with appropriate units and uncertainties if available. Fully reference each source. Measure the power output of your heater at a range of supply voltages up to a maximum of 12V. Estimate the rate of change of temperature at each input power. Decide upon and justify the input power you plan to use. Heat up a block by placing it in hot water in sink for 10min. Dry block thoroughly. Record data to establish a cooling curve for the block. Carry out some online research to establish the standard school physics laboratory methodology. Report on your findings. Fully reference each source. Determine the resolution of each of your measuring instruments. Decide how you will minimise the uncertainty in your final value. Use calculations to justify the size of your final uncertainty. Determine the likely systematic in your measurements by comparing instruments making the same measurement. Report your findings. Using the preparatory work completed so far develop and justify your final strategy. carefully about the method and how you can minimise error and uncertainty. a clear method including the settings and variables you plan to use. Explain fully how your method will minimise or account for unwanted energy transfers. Carry out your planned method. Record your experimental data fully and in a clear format. Process your data graphically or numerically to establish your final value. Make a comparison of your final value with the accepted value. Comment on the efficacy of your methodology.
