Apologia Science. We are doing astronomy. It can work for many grades. They have biology and a couple of others too. For history, we are studying the states with www.enchanted learning.com I just make up my own. I also just found http://www.geomatters.com/
They have a lot of geography/history that is awesome.
Hope it helps,
Christy

I'm in the same boat as you Charity. I feel like I don't know all the new curriculums as well.
For history, we do co-op and Lauren [will be in 6th] is studying renaissance. For Emily there's a text book complete with study questions at the end of the chapter that a friend of mine recommended [she'll be in 9th]
Science, we do at co-op because I can't possibly reproduce the labs, etc at home due to all my other commitments , but we use Bob Jones for this.
Not sure if that will help or not...
Blessings,
Lisa

Charity,
I use Apologia with Victoria. I love it. They have programs for all ages and they are created just for homeschoolers. I can't say enough good things about them. I also use Christian Kids Explore with Brandon. It's good too. I find that it can be lacking in some areas so next year I am suplimenting it with some materials from Answers in Genesis.
For History I am using Story of the World with Brandon. We like it. I love the hands-on activities. For Victoria we are working through Streams of Civilizaiton.
Hope this helps.
Ruth
