PRESENTATION TASK Classroom Context: This performance assessment focuses on a high school science teacher, Mr. Swartz, who is preparing a unit on cells. Background: As part of the study on cells, Mr. Swartz would like to present to his students a brief slide show presentation outlining the four stages of cell mitosis. He would like to have each slide in the presentation advance manually. Available Files: Graphics can be found on same wiki page as this presentation practice problem.
The Task: Mr. Swartz has asked the Master Technology Teacher for assistance in creating the presentation. Using your knowledge of presentation software, create a model slide show presentation to Mr. Swartz’s specifications. In creating this presentation, you should: • Create an introduction slide that provides the subject, date and teacher’s name. • Create slides 6 through 9 using the files provided by Mr. Swartz. Each slide should • Contain a title, an appropriate graphic image and text provided displayed as a bulleted list. • Animate the entry of the text of slides 6 and 8 (the animations should occur automatically and not require a mouse or keyboard click). • Animate the entry of the graphics in slides 7 and 9 (the animations should occur automatically and not require a mouse or keyboard click).
Formatting: • Use appropriate transitions to communicate effectively without distracting from the content of the presentation. • Use a color scheme appropriate for audience members including those who may be color-blind. • Use the principles of design to format the text and graphics to communicate to the intended audience. • Provide a brief explanation defending your selections above in the notes section of the introduction slide.

Cell Mitosis Mr. Swartz April 2, 2013
Interphase • DNA has replicated, but has not formed the condensed structure of chromosome. • They remain as loosely coiled chromatin. • Nuclear membrane still intact to protect the DNA molecules from undergoing mutation.
Prophase • The DNA molecules progressively shorten and condense by coiling, to form chromosomes. • The nuclear membrane and nucleolus are no longer visible. • The spindle apparatus has migrate to opposite poles of the cell.
Metaphase • The spindle fibers attach themselves to the centromeres of the chromosomes. • The fibers align the chromosomes at the equatorial plate.
AnaphaseandTelophase • The spindle fibers shorten and the centromere splits. • The chromosomes reach the poles of their respective spindles. • Nuclear envelope reform before the chromosomes uncoil. • The spindle fibers disintegrate.
