Have just been reading an ESchool Newsletter about a science web site for schools.
The Siemens Foundation and Discovery Education have unveiled their new web site aiming to engage students in science education. They provide videos and hands-on activities for earth, life, and physical science to help educators turn their students into aspiring scientists.
I have been looking around the site and it is great. Teachers will find many ideas for their classrooms in here.
You need to sign up to enable you to down videos for example. They obviously think that only people from the USA are going to sign up as you need to give data about your school and give the State you reside in but just ignore those bits and the sign up goes through OK.
