School: Happy Valley High School, Elizabethton, TN
Planned By: Tucker Carter
Original Author: Tucker Carter, Elizabethton
Instructional Objectives:
1. When asked to do so the student will state the parts of a chromosome. The parts of the chromosome will include DNA, sister chromatids, and centromeres.
2. Upon request from the instructor the student will describe Interphase as it relates to the cell cycle. The description should include a period of normal cell growth and activity.
3. When asked to do so the student will list the four phases
of Mitosis in order with 100% accuracy. Prophase, Metaphase, Anaphase and Telophase.
4. Given a short answer question the student will describe the process of cytokinesis. The description will contain cell pinches in half, daughter cells form and each daughter cell contains a set of identical chromosomes.
5. Given that Prophase is the first phase of Mitosis the student will explain what occurs during this phase. The explanation will include: chromatin condenses into chromosomes, centrioles split, spindle fibers begin to form and nuclear membrane breaks down.
6. Given that Metaphase is the second phase of Mitosis the
student will explain what occurs during this phase. The explanation will include: chromosomes line up in the middle of the cell, each chromosome attach to spindle fiber.
7. Given that Anaphase is the third phase of mitosis the student will explain what occurs during this phase. The explanation will include: sister chromatids separate into chromosomes, move to opposite ends of the cells.
8. Given that Telophase is the fourth and final phase of mitosis the student will explain what occurs during this phase. The explanation will include: chromosomes gather at the poles of the cell, chromosomes lose their distinct shape, two nuclear membranes form.

Procedure
1. The students opening activity will be to answer the question: How to we go from a fertilized egg to a full grown adult?
2. The teacher will provide a PowerPoint presentation over the process of mitosis covering each step of cell division.
3. The students will be provided with pipe cleaners for guided practice on how the different phases of Mitosis work.
4. The students will use the pipe cleaners and chalk to manipulate the chromosomes as they proceed through Mitosis.
5. Each group of students will then present their versions of mitosis for discussion.
5. With the addition of the tablet PC's the students will be able to access the diagram feature and draw the stages of mitosis themselves.
6. Upon completion of the drawings, the students will then be able to complete their own animations that they may send to each of their classmates.
7. Upon completion of the sharing portion of the activity, students will research different mitotic animations using their tablets and the internet.
8. As a class we will discuss the significance of the process of mitosis and how the process affects their everyday lives.

Management: 1. Students have assigned seats with assigned lab partners.

2. The students will follow established rules and procedures for the class.

3. Rules and procedures were established at the beginning of the semester.

Materials: 1. PowerPoint presentation
2. Text book for student reference.
3. Computer and projector for PowerPoint presentation.
4. Pipe cleaners and chalk for demonstration of cell as it proceeds
through Mitosis
5. Tablet PCs

6. Software


Comments
These lessons are developed for my classes and the classes of my co-teacher. We are team teaching a group of some 300 students. The majority of our students are from socioeconomically disadvantaged families in rural East Tennessee
Cross-Curriculum Ideas
The use of the tablet PC's enables me the teacher to introduce many of these students to technology they may have never been exposed to. There is also an artistic element to this lesson.
Follow-Up
One of the follow up activities will be to use the tablet PC's to compare and contrast the processes of mitosis and meiosis. The students will be able to keep a digital copy of their animation of Mitosis to compare with a new animation they create for meiosis.
