In First-hand Investigations, students must carry out an experiment and obtain data themselves. Students must be able to discuss the variables in the experiment, and assess the method and the result in terms of reliability, accuracy and validity, and suggest improvements. We include observations of the night sky and demonstrations of the models which have been proposed to explain them. When you take repeated measurements you need to work out the percentage uncertainty in a different way. This course provides you with the opportunity to develop experimental methods and techniques for analysing empirical data. A lot of this you already know, but there are quite specific ways to deal with errors and uncertainties at A Level. It appears that you have disabled your Javascript. First-hand investigations – What experiment? The governing equation for a falling object is given by: We plot the independent variable on the x-axis and the dependent variable on the y-axis. if the equation gives force, but you measured mass. (d) plotting and interpreting suitable graphs from experimental results, including. Use a heavy object that is streamlined to further reduce the effects of air resistance. To measure the acceleration due to gravity g by dropping a ball.

Assess the validity, reliability and accuracy of any measurements and calculations, Determine the sources of systematic and random errors, Identify and apply appropriate mathematical formulae and concepts, Draw appropriate graphs to convey relationships. Investigate the relationship  between the  range of a projectile and the height from which it is released up a ramp, Investigate the relationship between the range of a projectile launched horizontally and its velocity, Investigate the relationship between the range of a projectile and its launch angle, s is the height the ball fell (the independent variable), u is the initial velocity, u = 0 in this experiment, t is the time it took to fall (the dependent variable). This paper reports on a study which sought to find out teachers’ views and practices on the assessment of Advanced Level (‘A’ level) physics students’ practical work skills. The experiment is reliable as the data points were all very close to the line of best fit. GCSE Physics Practical skills learning resources for adults, children, parents and teachers.
