Science Worksheets and Study Guides Sixth Grade. Diversity of life

The resources above correspond to the standards listed below:

Washington Standards

WA.4. Life Science
LS1. Structure and Function of Living Organisms
6-8.LS1. From Cells to Organisms: In prior grades students learned how structures in the body work together to respond to internal and external needs. In grades 6-8 students learn that all living systems are composed of cells which make up tissues, organs, and organ systems. At each level of organization, the structures enable specific functions required by the organism. Lifestyle choices and environmental conditions can affect parts of the human body, which may affect the health of the body as a whole. Understanding how organisms operate as systems helps students understand the commonalities among life forms, provides an introduction to further study of biology, and offers scientific insights into the ways that personal choices may affect health.
6-8.LS1B. Students know that one-celled organisms must contain parts to carry out all life functions.
6-8.LS1B.1. Students are expected to draw and describe observations made with a microscope showing that a single-celled organism (e.g., paramecium) contains parts used for all life functions.
6-8.LS1E. Students know that in classifying organisms, scientists consider both internal and external structures and behaviors.
6-8.LS1E.1. Students are expected to use a classification key to identify organisms, noting use of both internal and external structures as well as behaviors.
