1 HG Feb 2012

2 Objectives To be aware of the requirements in KS4/5 To gain experience of datalogging experiments that could be done in KS4/5 To produce graphs of data from an experiment and present it to the group To identify and discuss advantages and difficulties/challenges of datalogging and how they might be overcome

3 KS4/AQA Use sensors and dataloggers to capture data in practical work – heat transfer – describing movement of a body moving in a straight line – finding kinetic energy of moving bodies – potential differences in d.c. and a.c. supplies from oscilloscope traces

4 KS5/Edexcel Determine speed and acceleration, for example use light gates Use, for example, light gates to investigate the speed of a falling object Demonstrate an understanding of how ICT may be used to obtain current-potential difference graphs, including non-ohmic materials and compare this with traditional techniques in terms of reliability and validity of data Use of, for example, light gates and air track to investigate momentum. Use of data logger to obtain I-t graph for a capacitor Use a data logger to plot V against t as a magnet falls through a coil of wire Measure specific heat capacity of a solid and a liquid using, for example, temperature sensor and data logger Use temperature and pressure sensors to investigate relationship between p and T Use a motion sensor to generate graphs of SHM

5 Practical Session Set up and run the experiments Whilst you are doing it make a note of any advantages/issues of each experiment Save data for at least one experiment Use your laptop or a SCR to open your data in Excel and produce a graph (or use your laptop) Bring it back after the break

6 Discussion View and discuss graphs from Excel In the circus: Any advantages of datalogging? Any challenges/difficulties? How might they be overcome?
