I hesitated to post this because the site looks so unprofessional (with its ads and weird layout). But the content is really really great. It's goes way beyond the typical "connect a battery to a lightbulb" type of kids' science.
Agreed on both points. It's a shame that its layout is so poor, I'm sure many must leave the site as soon as they see that, assuming that the quality of the design reflects the quality of the content.
