Children's interests begin earlier than at 15 years.
Children choose their areas of interest when they are around 15 years.
If we spend our attention only on the older-than-15, we get questions from those who are already interested: we are too late!
Therefore, lack of pupils that choose physics studies means a special effort must be made to create a specific site for them.
A kid's corner (or better "Young Scientist Corner", as teenagers don't want to be called kids) on the web needs to be friendly, funny, attractive to get their attention and suitable for their interests.
