7G – Upper School Science – Cellular Organization
The focus of this Core Experience Learning Lab is an investigation into the organization that exists within organs, tissues, and cells of animals and plants and into the functions that can be inferred from this organization. Beginning at the organism level, students soon see that an organism can be broken into a series of systems, into organs which comprise this systems, into tissues which comprise organs and then into cells which comprise tissues. Further division is apparent when cells are examined, and students see that each cell has separate components called organelles. This particular organization of structures within biological systems is often referred to as hierarchical organization. Images from x-rays, CT and MRI scans provide students with a window through which to begin viewing this hierarchical organization. Further lab studies are done via oil immersion light microscopes and tissue samples from various organisms.
