Our current science unit is all about plants. We've planted our garden, read books about planting and seeds, are working on a seeds lapbook, and starting this past week we began a five week Tops Science unit about corn and beans. This unit came from Sonlight science, so they sent everything we would need in a nifty box - boy, did that make preparing for this unit EASY! (If you get the stand alone unit, however, the teacher's guide is very specific about what you will need, and it's a lot of common household items.) The webiste also provides a TON of teaching tips and resources.
The very first day my daughter made her lab journal - very official for her. There are 25 total days in this study, and most of the days have lab sheets to fill out in detail. It was easy to assemble, and then she decorated the cover.
This particular unit is recommended for grades 4-10. It is challenging, but nothing we can't handle, and I love the sophisticated, yet humorous layout of the lessons. Here's a sample from their website:
I would recommend science from Tops - looks like they have a ton of resources/materials to choose from. We're enjoying it so far!
