Hi! We are finishing up with Adventures and I will be honest I found the little Usborne books do have quite a few experiments, but I LOVE the First Encyclopedia of Science. There are sometimes experiments, but, ahem, if it is a crazy week I might skip. (my turn to hide)
I have found the book to be a good sit and read book. I actually so far love that series. My two little ones will occasionally listen in, the usual assigned readings are 2 pages for the day, very doable and not scheduled every day.
If I thought it was a "heavy" topic, like light, I might review, "So light moves fast, light moves in straight lines" etc. Then having them repeat back. Sometimes, I even put a post-it note to mark the pages I read, then stick it in the book basket for them to look at later. I also have the First Ency. of the Human Body that I bought years ago, the kids pull it out time and again. There is a two week (or three?) in Adven. on the human body, this was a nice add in for us. I think there might be some science-y books listed in the book basket...
There are experiments in Adven. that go along with the theme, yeast for example during the "Jesus is the bread of life" unit. I would think you could skip, maybe make bread as suggested and just move along. Seriously, I know you said to not tell you this, but I did find the experiments to be quick. Once the materials were gathered on my kitchen counter, explain the concept, do the little thing, it was quick. Nothing took a long time. I do remember there was one experiment with heat and air, used a radiator! I skipped that one.
I have two littles who are close in age, 10 1/2 mons., so for the longest time experiments didn't always happen here either. Years ago, my mom had 7 preschoolers at one time and she said science was nice, but it would just have to wait. It is a season, I think as the kids get older it will be easier and it will be more fun too. That's why I stopped when my girls were under 4. It just wasn't fun, I was tense and it became a huge mess.
That's when we started looking to add little fun science kids books to our bookshelves. Things to read, things to color.
Oh, have you looked at Christian Liberty Nature Readers? The K book and 1st grade book have nice science stories, my kids adore the stories and two years ago, before we switched to MFW, it was our science. I might have had them draw pictures of ants or draw a spider or different webs while I read. It was simple.
((hugs)) Hope that helps some.
ps. And we adore the Bird Book!! Lots of neat pictures....
