1. Topic-
Mitosis
 
2. Content-
Mitosis is nuclear division to create identical cells: interphase, G1, S, G2, Mitosis, prophase, metaphase, anaphase, telophase, cytokinesis, chromatin, chromosome, centriole, centromere, spindle
 
3. Goals: Aims/Outcomes-
To learn the steps of the cell division
 
4. Objectives-
1.Students can draw the steps of the cell cycle, complete with labels
2.Students can answer multiple choice questions identifying the stages of mitosis and cell cycle
3.Students can explain what would happen when presented with errors in mitosis. After listening to a lecture, students will be able to define mitosis and its steps with 90% accuracy.
 
5. Materials and Aids-
mitosis models, paper, Asexual Reproduction/Mitosis PowerPoint handout, Prokaryotic and Eukaryotic Cell Division WS (#124), Types of Asexual Reproduction WS, Section 10-2 Worksheet/Reviewing Key Concepts, Mitosis Skit directions and Journal entry prompt, Stages of Mitosis Worksheet, Prentice Hall Biology Textbook, Notebook, and Pencil.
 
6. Procedures/Methods-

A. Introduction-

1. How does your skin heal after you get hurt?
2. How do you get more cells as you grow?
3. Review and Focus. Students will enter class and begin with a bell ringer asking how animals grow. They will write this in their notebook and discuss with their peers their various responses. Responses will vary. I will begin with a discussion of the importance of cell division (growth, tissue repair and asexual reproduction). This Bell Ringer will assess students��s prior knowledge of cell division.
 

B. Development-

1.vocabulary fold-ups
2.review definitions in PPT
3.draw and label steps on the board

4. Teacher Presentation. After the bell-ringer, I will begin with a mini-lecture on asexual reproduction and mitosis. The goal of the lesson will be to introduce the cell cycle to students and to give an overview of the phases/stages of the cell cycle. Next, students will read a passage on prokaryotic and eukaryotic cell division. This will show students how mitosis works in different organisms. Students will answer questions related to the passage. Students will then complete a worksheet with the different types of asexual reproduction (binary fission, budding, sporulation, regeneration, parthenogenesis and vegetative propagation). They will then give two examples of organisms that use each method of reproduction. Time will also be allotted to clear up any misconceptions about the terminology used when discussing cell division (mitosis and meiosis are not interchangeable).
 

C. Practice-

1.students read and answer questions about mitosis
2.students take notes about mitosis
3.students draw and label the steps of mitosis
4. work with models on small groups. Guided Practice. After the discussion about asexual reproduction and mitosis, the students and I will go through a worksheet (#120) that describes the series of events in each phase of mitosis to assess their understanding of the lecture and textbook readings (section 10-2).
 

D. Independent Practice-

1.worksheets to assess knowledge of mitosis
2.draw and label cell cycle in class independently
 

E. Accommodations (Differentiated Instruction)-

Students who are identified as SLD will be given extended time and may take the assessment home and use their textbook. This will also allow for a separate setting/room needed when being tested.

1.models
2.more time
3.real-world worksheet
 

F. Checking for understanding-

1.in class assessment and feedback with students
2.individuals draw stages on board and clarify group understanding
3.grade and return work
 

G. Closure-

Closure. To close, students will receive a worksheet with visual representations of the stages of mitosis. They will number the six diagrams of the stages of mitosis in animal cells, then plant cells, in the proper order. Students will then label each stage with the proper name.

1.How do cells replace themselves?
2.Where do cells come from when you need more to heal or grow?
 
7. Evaluation-
Quiz - if 80% or higher of students score 90% or greater then the class will move to meiosis, if not then mitosis will be retaught at a later date.
