One of the very Intresting presentation which I liked most. Story of this presentation goes like this. Aditya and Nachiket conducted a Science Camp (Vigyan Shibir) at Jnana Prabodhini Prashala, Pune in May 2008. I was asked to make those school children aware of scientific methadology, and rational behind experimentation. I then took example of Great Scientist Niko Tinbergen with his experiments and taking those examples we discussed the importance of 'Controls' and 'Sample Size'. The presentation was more of interactive than detailed informative and lukily students liked a lot.
