In my previous posts, I have mentioned using Building Foundations of Scientific Understanding for our elementary Science. We have been working through A thread (Nature of Matter) of BFSU Volume 1 all year. I had originally planned for us to start in Volume 2 and continue A thread (this is the Classical schedule coming through…), but over the past several weeks there has been a lack of interest in continuing with atoms and molecules. I think the beautiful weather outside has a lot to do with it! So I did some thinking and decided to reevaluate how we are doing our science.
Bernard Nebel, the author of BFSU, encourages moving between the four “threads” or disciplines (Nature of Matter, Life Science, Earth and Space Science, and Physical Science). I’ve resisted this only because we’ve followed the classical schedule for the past several years, with one subject each year in a four year cycle. But as we move away from the classical schedule a bit, I find myself wanting to jump around a bit (though in an organized way so not stress out my Type A personality).
With that being said, I decided to cover Plants this June. Everything is in bloom, the weather is nice, and we’ve got a great garden in our front yard to study as well.
Over the past week or so, we have been studying the basic structures of plants. The core of our lesson has been B10: Plant Science I – Basic Plant Structure. We started with the three basic parts of a plant – roots, stems, and leaves. We discussed how even vastly different plants all have these parts, though often in a modified form. She was fascinated to learn that the spines of a cactus are actually highly modified leaves.
We have a membership with Notebookingpages.com, and I printed up several pages from the Plant Study collection. Over the past week, we have been working through these pages, identifying various plant parts, margin types, leaf arrangements, etc. The Visual Dictionary of Plants is a wonderful resource for learning plant parts.
Kyri and I went on a Plant Walk this week, armed with a few nature books and plant identification guides. As we explored, we discussed the three basic parts of a plant, and I asked her to identify various aspects of plants we found, such as:
type of leaves – simple or compound
arrangement of leaves – alternate, opposite, whorled, fascicled, or clustered
leaf venation – parallel, pinnate, palmate or arcuate
leaf margins – smooth, serrate, dentate, crenate, sinuate, lobed, or cleft
On our plant walk, she was particularly interested in finding a Sweet gum tree, because she had read about it and its identifying features in one of her books. We wrapped up our walk with the triumphant discovery of a Sweet Gum tree at the end of our street.
We have built up quite a collection of nature study books, and Kyri absolutely adores them. I can often find her with one or more tucked under her arm. Here are some of our favorites:
Here are several pictures from our walk!
