Ecology - Biodiversity Lab
Studnents examine the degree of biodiversity that exists in one's everyday environment, in order to develop an understanding of how scientists classify organisms and to explain why biodiversity is important for living things.
Curated OER
Patchwork Quilts
Fourth graders examine about traditional quilting patterns, the symmetry in such patterns, and practice creating patterns of their own. They design a quilting pattern, and groups make colorful "patches," of a pattern. They assemble the...
