Science Curriculum

My latest obsession has been Science.  What science program should I use for next year??  How much emphasis should I put in to 2nd grade science?  Is one day a week sufficient?  Two days?  If I did it that long, could I plan it right so that his curriculum could last for two years??  Is that too slow??  Am I OCD?

For the last question, there is no doubt to my OCD status...I am!!  I think most of us have a certain degree of OCD in them, but I do tend to take it up a notch or two (or three).  I am already working on his schedule for next year.  I am putting together his notebooks and getting lesson plans in order or at least started (kinda hard to plan some when I have yet to get the curriculum for certain subjects).  I was organized for his 1st grade year...but I want to go to the next level....need is more like it.  

But, back to science.  I found a curriculum that I am pretty set on.  It is called Considering God's Creation and it looks just fantastic.  It is for 2nd through 8th grade, so I would not feel bad making it stretch 2 years or even more if I can.  Lord knows I have lots of resources online to help come up with activities to make each topic last just a bit longer without boring him or I.  It is such a delicate balance to do a topic or curriculum that you like without becoming bored.  I found myself becoming bored this past year with a couple different subjects because we just seemed stuck.

What I like about Considering God's Creation is that it does not cover one topic for the whole year.  I found when Sierra started homeschooling that a popular science curriculum would have you studying one area for a whole school year and it bored her and I to tears.  This one covers:

Universe
Stars
Solar System
Earth
Light
Sound
Wind
Weather
Clouds
Rocks
Plants
Insects
Mammals
Reptiles
Birds
Fish
Amphibians
Food Chains
Reproduction and Genetics
Human
Animal Anatomy
Physiology

With so many subjects covered, it seems to me that we can make this last for at least 2 years, especially if we work on science 2 times a week.  I am pretty excited about it.  I think it will be GREAT fun and I look so forward to 2nd grade with Daniel.

My next obsession is Bible.  *sigh*  Curriculum floats around in my dreams at night.  I find myself overwhelmed in a store full of different curriculums and they are al
