General Lesson Information
 Lesson Plan ID: 33344 Title: Modeling Mitosis Overview/Annotation: This module provides three different methods for learning about mitosis and includes hands-on, inquiry-based activities. Students will prepare and examine slides of their cheek cells and compare them to those of other students. This will demonstrate the relationship between the structure and function of cells and the similarity of the same types of cells within the same species. Using yarn and popsicle sticks, students will model and explain each of the stages of mitosis. The students will observe prepared slides of onion root tips and whitefish blastula to discover the differences in mitosis in plant and animal cells.
Associated Standards and Objectives
Content Standard(s):
 Science SC2015 (2015) Grade: 7 Life Science 2 ) Gather and synthesize information to explain how prokaryotic and eukaryotic cells differ in structure and function, including the methods of asexual and sexual reproduction. NAEP Framework NAEP Statement:: L8.1e: All organisms are composed of cells, from one cell only to many cells. About two-thirds of the weight of cells is accounted for by water, which gives cells many of their properties. In multicellular organisms, specialized cells perform specialized functions. Organs and organ systems are composed of cells and function to serve the needs of cells for food, air, and waste removal. The way in which cells function is similar in all living organisms.† NAEP Statement:: L8.2: Following fertilization, cell division produces a small cluster of cells that then differentiate by appearance and function to form the basic tissues of an embryo. NAEP Statement:: L8.9a: Reproduction is a characteristic of all living systems; because no individual organism lives forever, reproduction is essential to the continuation of every species. NAEP Statement:: L8.9b: Some organisms reproduce asexually. NAEP Statement:: L8.9c: Other organisms reproduce sexually. Unpacked Content Scientific And Engineering Practices:Obtaining, Evaluating, and Communicating InformationCrosscutting Concepts: Structure and FunctionDisciplinary Core Idea: From Molecules to Organisms: Structures and ProcessesEvidence Of Student Attainment:Students: Gather and synthesize information with attention given to accuracy, credibility, and bias. Explain, based on gathered information, the differences between prokaryotic and eukaryotic cells as they relate to structure, function, and methods of reproduction.Teacher Vocabulary:Cell Prokaryotic cells Eukaryotic cells Structure Function Asexual reproduction Sexual reproduction Mitosis Meiosis Chromosome DNAKnowledge:Students know: Prokaryotic cells are microscopic, single-celled organisms that have neither a distinct nucleus with a membrane nor other specialized organelles. Prokaryotes include the bacteria and cyanobacteria. The function of prokaryotic cells. The reproductive methods of prokaryotic cells. Eukaryotic cells consist of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaebacteria. The function of eukaryotic cells. The reproductive methods of eukaryotic cells.Skills:Students are able to: Obtain information about cells, including structure, function, and method of reproduction, from published, grade-level appropriate material from multiple sources. Determine and describe whether the gathered information is relevant. Use information to explain how prokaryotic and eukaryotic cells differ.Understanding:Students understand that: Prokaryotic and eukaryotic cells differ in structure and function, as well as method of reproduction.AMSTI Resources:AMSTI Module: Investigating Biodiversity and Interdependence Studying the Development and Reproduction of Organisms

Local/National Standards:

Primary Learning Objective(s):

1. The student will prepare a wet mount slide with a sample of his or her cheek cell and identify the cellular structures displayed in the sample.

2. The student will model mitosis to identify and describe the process in full or in any one of the stages.

3. The student will recognize and sketch one of the stages of mitosis from prepared slides of an onion root tip and a whitefish blastula.

4. The student will explain mitosis to group members while modeling the process.
