This used to be a great site. In the last few years, I've seen the projects drift from teaching real science and engineering concepts to simply offering instructions (that sometimes work) to a result. The kids in my class get confused on the concepts where they weren't before.

Several of the new projects also use fancy web features - which is cool - except they won't load on the older Windows and Macs the kids have. If you have Windows 7 or OSX more than a year old, the slideshows and tabs don't display. That's a pretty big problem for a kids' science site.

If they have questions they used to be able to get good answers in the expert's forum. They still can if it's a chemistry or biology question. They don't seem to have experts in physics, robotics or electronics now. It's sad to see a once-great site go downhill. If I didn't love it so much before, I would have given it one star instead of two.
