What is this session about
Combining a variety of tools
It is now possible to combine a variety of easily available tools to do conventional lab experiments more effectively (even at home)
Smartphones, free software and spreadsheets
A combination of tools can enable students to record and analyse data accurately and conveniently
Transferable skills
Once students get a hang of these methods, they are able to apply them to do other experiments very easily
What do we discuss in this session?
In this session, we take up a conventional Physics experiment – namely, charging and discharging a capacitor/RC circuits, and apply a combination of novel methods to see how it can be done more effectively. Also, it is straightforward to imagine using these methods in similar yet diverse situations to perform sophisticated Physics experiments.
- Using smartphones to record readings
- Tracker – a free/open source Physics education software to analyse videos
- Using Solver tool in Excel to fit data to a theoretical model
