I'd like to have a structured weekly lesson plan for them just to keep them busy. Christian based is preferred, but not neccessary.

we really love Living learning books science. You use the core books it sugests along with books to check out from the library. It keeps us busy. What I like about this one is the variety of hands-on projects including cooking :)

We have also enjoyed Sonlight Science. Good thing about this one is that you don't have to use the library. You can buy everything you need upfront.

We also have Apologia Elementary Astronomy. It looks good, but we have not started it yet.

I was going to say all three of those, too!

We have been using Living Learning Books science this year and have enjoyed it a lot.

I recently ordered Sonlight Science 3 and it looks like it's going to be a lot of fun.

And i have heard really good things about the new elementary Apologia science.

I agree with Chelsie and Heather! We've used Living/Learning Science and enjoyed it. Now we're using Sonlight and will continue to use it - it's been a big hit here.

I have Apologia on the way for Brianna next year - she's 12.

Here is a science curriculum that looks interesting. http://www.myworldscience.com/

We use Apologia and love it, but I have not tried there elemetary versions.

We looked at Rainbow and it also looked great but very $$
