Seeds are sprouting!

Part of the fourth grade curriculum is seeds. We've been sprouting and measuring the growth of roots, stems and leaves. I was somehow lucky this year to have a range of samples of the order of growth. Check these out! It starts with "swollen" (the sunflower seed that had soaked up water but not yet sprouted), "seed coat off" (a bush bean that swelled up and pushed out of it's outer lining), "root growth" (the bush bean having a sprouted root) and "stem with leaves" (a pea that has both a root and a stem with leaves growing). Just some cool "science-ie" things I thought I'd share....

Seed growth

This view is backwards, but you get the idea...
