Metamorphosis- the life cycle of a butterfly

 * Students will be able to understand the 4 stages of the life cycle of a butterfly.
 * Students will understand the new science vocabulary words: hatch, larvae, molting, pupa, chrysalis, metamorphosis.

**__Preparation:__**

 * Purchase butterfly kit.

=
Purchase a [|butterfly kit.]from the following website: The Butterfly and Nature Gift Store, (__[|http://www.butterfly-gifts.com/live-butterfly-kits.htm.]__=====
 * Prepare science vocabulary cards.
 * Test Media/Smartboard: 1. Video of Life Cycle of a Monarch butterfly, 2. Voicethread Review of Life Cycle of a Monarch butterfly, 3. Photostream of butterfly pictures.


 * For use in Extension Activity for 1-2 grades, create a Diigo list of websites for research of Pennsylvania butterflies and a list of websites for research about Monarch migration.
 * For the Conclusion Activities - bowl and objects to put into the bowl. (see activity for examples)

Media #3: **Photostream** of butterflies (Saved pictures from a public search on Flickr- Search Flickr for butterfly pictures, save as a "favorite", show as slideshow by logging onto Flickr account and project on Smartboard or projector).=====

__**Instruction:**__

 * Develop background knowledge - Show photostream (Media #3) of butterflies. Discuss student experiences with butterflies and with caterpillars.
 * Explain that butterflies go through a cycle o f changes before becoming butterflies and the cycle has 4 stages and that in one of the stages the butterfly is a caterpillar. Say, we know one stage is butterfly, one is caterpillar, what are the other two stages? Explain that you are going to watch a video showing the 4 stages of the life cycle of a butterfly and that they are going to be able to tell you what the other two stages are after the video.
 * Vocabulary- using word (with pictures) cards, introduce the rest of the vocabulary words: egg, hatch, larvae, pupa, chrysalis, metamorphosis. Put each card (magnetized) on the white board where you keep science vocabulary for easy reference and frequent reinforcement and practice.
 * Show the Monarch Butterfly video (Media #1), 2 minutes. Explain that you are going to be growing your own butterflies in the classroom and chart the progress each day together.

Keep a daily classroom log for the observed changes of the butterfly project. This could be done as a class and logged by one student each day. Students will also predict what will happen next. > K-2: Learning reinforcement of the 4 stages: Egg, Larvae, Pupa/Chrysalis, Adult.
 * __Activities:__**
 * Activity: Set up and Introduce Butterfly Kit to students.
 * Activity: Voicethread commenting - Use the above Voicethread (Media #3) to support instruction on the life cycle of a butterfly. Each slide poses a question to the student. First show the Voicethread to whole class and then have students work independently or in pairs to add comments to each slide. Review as whole class afterwards on SmartBoard, reading all the students' comments. Students cold participate in "clicking" the voiceboxes on each slide.
 * Activity: Life cycle coloring page. []


 * __Extension Activities (for 1-2 grade):__**
 * Vocabulary additions: host plant, migration.

List of butterflies in Pennsylvania: [] Students will use Diigo list (teacher prepared) for research.
 * Ext. Activity: Pennsylvania butterfly project- Study the different kinds of butterflies in Pennsylvania. Pairs of students choose one PA butterfly and complete a fact chart. Facts to be included in this project- Butterfly Family, host plants ( picture), adult stage food, wing span, adult butterfly picture.
 * Ext. Activity: Migration of Monarch Mapping - In the Voicethread (Media #2), migration i s mentioned. Students could be instructed to research the Monarch migration from a Diigo shared list of sites and in the Voicethread commenting activity (above) they would add a fact about the migration that they learned in their research.

Plan and plant your own butterfly garden on school grounds. Get parents involved!
 * Ext. Activity: Plant a Butterfly Garden []


 * __Conclusion/Assessment:__** Centers: Small groups cycle to three centers.

//**Center One**:// How do caterpillars stay healthy and grow? Circle Discussion Game - Socratic method discussion. Preparation- Bowl of misc small objects or pictures (candy bar, toothbrush, apple picture) one for each student. Students sit in circle on floor: One by one, student picks from the bowl and teacher asks questions. Example: student picks candy bar. Teacher asks is that something a caterpillar eats? Why not? What does a caterpillar eat? Each student get one turn.

//**Center Two**//: What is the order of the Life Cycle of a Butterfly? Sequencing of cycles on Pocket Chart- using pocket chart and laminated cards with pictures, students place cards in order of cycle.

//**Center Three**//: What is metamorphosis? Charades- Preparation - the 4 cycles written on small papers and put into a hat, students take turns choosing one, and demonstrates that cycle. After all 4 cycles have been demonstrated, all students together demonstrated all 4 cycles and call out what the stage name is when they are doing it.
