Ask Slashdot: Online Science For 8th Grade Students?

Peterus7 writes "I'm a student teacher in an 8th grade science classroom, and have noticed that students are very motivated by anything online. After realizing that, I've been looking for ways to incorporate internet resources into my teaching, and trying to find cool citizen science projects, activities, and simulations that would be appropriate for a grade school science class, such as galaxyzoo and fold.it. So, I'm asking slashdot for more resources that could help bring science to their lives. Thanks!"
