Cell Organelle Assignment
Lesson Plan Outline: Human body with 30 to 40 trillion diverse (200 types) cells (plus equal number of resident microbes) organized in simple to complex levels (chemical, cellular, organ, organ system, organism) can be an excellent resource to make a connection at multilevel of hierarchy and interconnectedness.
In biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction.
The three tenets to the original cell theory were:
The generally accepted tenets of modern cell theory include:
An analogy is a similarity between concepts. Analogies can help students build conceptual bridges between what is familiar and what is new. Often, new concepts represent complex, hard-to-visualize systems with interacting parts.
Analogies can serve as early “mental models” that students can use to form limited but meaningful understandings of complex concepts. Analogies can play an important role in helping students construct their own knowledge, a process that is encouraged in the Standards and consistent with a constructivist view of learning. As students’ develop cognitively and learn more science, they will evolve beyond these simple analogies, adopting more sophisticated and powerful mental models.
Assignment:
Fill in the chart below while reading information at the Cells: A Busy Factory site. In the second column of the chart, write the name of the organelle that functions most like the factory worker described in the first column. In the third column, write a brief description of the function of the organelle in the cell.
The product of the factory is PROTEIN.
