Experimentation is a critical aspect of any science education. Smartphone can be an effective teaching aids in this journey. Concept clarification activities can include data feeds from various sensors in smartphone.
Gathering data and analyzing the same forms a key phase in any enquiry based activity. Many smartphone apps help students with these phases.
More than 40 physical measurements are possible with the sensors available in smartphone.
