Students will observe that biological organization is a hierarchial system of classification in which each successive level is more complex than the lower level, and each successive level has properties that did not exist before. Students will sequence the levels of organization and make a foldable that lists and describes the levels.

This video lesson instructs students in the hierarchical organization of multi-cellular organisms. Each level of organization is identified and defined. The four types of tissues are discussed in detail. Supplemental materials include a transcript of the video and a quiz for assessment.

In this investigation, students will observe cells from various sources of their choice. Plant, animal and bacterial cells will be observed as well as cells from multicellular organisms and single celled organisms. Students will be expected to provide written descriptions as well as detailed drawings of the cells they observed. Students will be asked to compare and contrast the cells they observed and provide a technique they would use to categorize the cells they observed.

In this lesson, students will learn how the components of a cell operate as a system. Students will discuss the meaning of the word "system" and then apply the definition to their observations of a paramecium, noting that the single-celled organism is only alive because all the components work together. They will also examine prepared slides of human body cells and compare to the paramecium.

Students will complete the different components of the Hyperdoc to learn more about unicellular and multicellular organisms.
