PRESENTATION TASK Classroom Context: This performance assessment focuses on a high school biology teacher, Mr. Hutto, who is preparing a unit on the life cycle of a butterfly - metamorphosis. Background: As part of the study on metamorphosis, Mr.. Hutto would like to present to his students a brief slide show presentation outlining the four stages of butterfly life. He would like the presentation to consist of one introductory slide that contains the egg stage and one slide on each of the other three stages, and he would like to have each slide in the presentation advance manually. Mr. Hguyen has provided a link to the graphics for the four slides that can be downloaded by clicking on the links below. Available Files: butterfly1.jpgbutterfly1.jpg (graphic image for slide #1) butterfly2.jpg butterfly2.jpg (graphic image for slide #2) branches3.jpgbranches3.jpg (graphic image for slide #3) branches4.jpgbranches4.jpg (graphic image for slide #4)
The Task: Mr. Hutto 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 Ms. Hernandez’s specifications. In creating this presentation, you should: Create an introduction slide that provides the subject, date and teacher’s name. Create slides 2 through 5 using the five files provided by Ms. Hernandez. 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 2 and 4 (the animations should occur ◦ Automatically and not require a mouse or keyboard click). ◦ Animate the entry of the graphics in slides 3 and 5 (the animations should occur automatically and not require a mouse or keyboard click).

The First Stage Metamorphis – Life Cycle of Butterflies Eggs are first stage They are tiny, sometimes microscopic Laid on the underside of host plant leaves Hatching predetermined by time eggs are laid
Stage 2 Caterpillars – the feeding stage Minute, some virtually invisible to naked eye Coloration of caterpillar is quite diverse Job of caterpillar is to eat, eat, eat Caterpillars must shed skin several times, each shedding called an instar Can multiply in size more than a thousand fold When final instar occurs, pupa emerges
Pupa - the transition stage Transformation in pupa stage is miraculous What emerges in no way resembles the caterpillar Complete disassembly of the cells and reassembling of cells into new form The butterfly emerges from this stage Stage 3
The Final Stage Adult Butterfly – the reproductive stage Upon emerging, the swollen body pumps fluid into tiny shrived up wings Within a few hours, wings are full sized, dried, and become more rigid Butterflies are ready to take flight The job of the adult is to mate and lay eggs Most live only one or two weeks
