MOCHO (www.mocho.pt) is the first Portuguese web portal on science and scientific culture. It is a project of the Centre for Computational Physics of the University of Coimbra, which is sponsored by the Portuguese programs "Nonio - 21(st) century" and "Ci (e) over cap ncia Viva". Students who are now attending primary and middle schools were born in the middle of the 80s and belong to the so-called net generation (or zap generation). They grew up in the digital era being, therefore, familiar with cell-phones, computers, Internet, etc. The challenge for them is to select information among the enormous amount which is available in the Internet. The offer of valuable scientific and pedagogical information which is made by "MOCHO" can be an important help for their work, both at school and at home. We describe the portal here.
