Datalogging@KS4&5HG Feb 2012
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
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
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
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
Discussion
View and discuss graphs from Excel
In the circus:
Any advantages of datalogging?
Any challenges/difficulties? How might they be overcome?
