Finding curriculum materials that are age appropriate, standards relevant and close to developmentally for our students is difficult at best, but with the addition of a science site to the Learning A-Z family may make life a little easier for us.
I'm sure many of us have either school based access or self-paid access to one of more of the Learning A-Z family (Reading A-Z, RAZ Kids, Reading Tutor A-Z, Writing A-Z, Vocabulary A-Z). Now there is a related site for science, called, of course, Science A-Z. Right now Science A-Z is not up and running, but you can down load three sample units, Animals, Water and Sound.
Now we await Social Studies A-Z, Math 1,2,3 and Life Skills Hand Washing to Laundry!
