Brief Summary of Unit: This butterfly unit has been created for second grade science, incorporating technology, reading and writing. The unit will be a ten-day study of the life cycle of a butterfly.
Students will Understand: *How to identify the parts of a butterfly.
*The lifecycle of the butterfly.
*How to create a classroom butterfly terrarium.
*The distinct stages in a butterfly creation.
*How butterflies migrate.
*How to use a digital camera and will write about photographed items.
*How to observe changes and journal them.

Link to Standards #1

Students will describe structures and attributes of living things, processes of life, and interaction of living things with each other and the environment.

Indicator:*To understand the nature, value and application of scientific knowledge.
*Demonstrate understanding and use a variety of processes for scientific investigations.
*Understand the fundamental structures, functions and mechanisms found in living things.
*Analyze various patterns and products of natural and induced biological change
*Analyze how organisms are linked to one another and the environment.
Benchmark(s):*Explore structure and functions in living things.
*Explore processes in living things.
*Explore ways organisms change.
*Explore how environmental factors affect living things within an ecosystem.
Other Content Standards:Science Standards:
*Describe how some animals (butterflies) go through distinct changes during their lives while others generally resemble their parents throughout most of their lives.
*Identify behavioral and physical characteristics of plants and animals that help them survive in their habitat.
*Describe how seasonal changes affect plants, animals and their surroundings (example; adaptation, migration, camouflage and adaptation).

Writing Standards:
*Distinguish between complete and incomplete sentences.
*Use correct grammar and vocabulary in a variety of sentence structures.
*Use descriptive detail and a variety of sentence types.
*Examine personal work and conference with others for capitalization and punctuation.
*Use technology to share writings with others and publish writing pieces.

Reading Standards:
*Recognize specific strategies that are needed to read different types of printed materials (example; science book, brochures, magazines, internet sites).
*Use knowledge of sentence structure and punctuation when reading.
*Describe cause and effect relationships in various text (example; why, what if, how, and when).
*Identify resources, which provide factual information.

Other Components
Essential Questions to Guide this Unit and Focus Teaching and Learning: 1. Is it fair to take the caterpillar out of its natural environment and bring it into the classroom?
2. Will the students actually see the changes?
3. What does a butterfly need in its surrounding to complete its cycle?
4. Why is the surrounding important to the development of the butterfly?
5. Which stage of development is the most important and why?
6. Why do butterflies migrate?
7. What do good writers do when they are journaling?
8. What types of butterflies are found in South Dakota?

Key Knowledge and Skills Students will Acquire: Upon completion of instruction the students will:
*Be able to identify the parts of a butterfly.
*Create a classroom butterfly terrarium.
*Understand the life cycle of the butterfly.
*Use a digital camera to use and write about the butterfly terrarium.
*Track the migration of butterflies.
Assessment Plan: Assessment will take place throughout the entire two-week unit by teacher observation, student journaling, labeling diagrams, creating a butterfly life cycle, and unit test.
Learning Activities: Lesson 1: What is a butterfly?
Lesson 2: Identify the parts of the butterfly?
Lesson 3: Butterfly environment
Lesson 4: Terrarium creation/Nature search
Lesson 5: Understand life cycle of a butterfly
Lesson 6: Build and label a model of the life cycle
Lesson 7: The life of an adult butterfly
Lesson 8: Migration of the butterfly
Lesson 9: Technology study of butterflies
(Digital Camera/Web site exploration)
Lesson 10: Creative writing about butterfly unit and digital photos.
Notes:*Activities in our unit can easily be carried out longer than the time allotted.
*Web sites are very helpful if searching for information/print outs on butterflies.
