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 to have each slide in the presentation advance manually.

Available Files:Graphics can be found on the same wiki page as this PowerPoint skills app.

The Task: Mr. Hut to has asked the Master Technology Teacher for ass is tance in creat ing the presentat ion .

Using your knowledge of presentat ion software, create a model s l ide show presentat ion to Mr. Hut to’s specif icat ions . In creat ing th is presentat ion , you should:• Create an in t roduct ion sl ide that provides the subject , date and

teacher ’s name.• Create s l ides 6 through 9 us ing the f i les provided by Mr. . Hut to.

Each s l ide 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.

LIFE CYCLE OF A BUTTERFLY-METAMORPHOSIS

Eggs are first stage

They are tiny, sometimes microscopic

Laid on the underside of host plant leaves

Hatching predetermined by time eggs are laid

Metamorphosis – Life Cycle of Butterflies

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 

CATERPILLARS – THE FEEDING 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

PUPA - THE TRANSITION STAGE

A D U LT B UT T E R F LY – T H E R E P RO D U C T I V E S TAG E

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
