Yeah, but it's actually a bit more, you know, scientific ^^
We don't do science fairs over here and I appreciate that the kind of experiment required by them is perhaps different to what one would conduct in a lab, but the same principles should apply. At the very least, don't just observe a behavioural trait. Observe it and ask yourself why that trait is present. Otherwise it's just diary-keeping, not something approaching actual science.
Make predictions. Collect data properly. Analyse and evaluate your findings.
If you believe everything you read, better not read.
