NPS Science Curriculum

Identify properties of mealworms/butterflies such as body color, parts, and number of legs.

Observe and identify the four stages of the life cycle - egg , larva, pupa, and adult.

Learn the term metamorphosis which describes the changes in body structure from larva to adult as it applies to various insects.

NPS Math Curriculum

Identify object by different attributes - color, shape, and size.

Count to twenty or more; recognize and reproduce simple patterns.

Identify object by the positional location (top, bottom, left, right).

Identify the seasons of the year.

Recognize standard verses nonstandard units of measurement, i.e. inch, centimeter.

Compare objects and determine size using visual observations (small, medium & large).

Identify similar figures and shapes (symmetry).

Make a bar graph.

Interpret a bar graph.

NPS Technology Scope & Sequence Objectives

Students open and save files to their own network drive (U drive/My Stuff).

Students collaborate in the creation of a multimedia slide show containing text and graphics.

Students type sentences.

Students use a web browser, buttons and hypertext links.

Students do a keyword search using an online encyclopedia.

Students use a word processing program.

Lesson:
Classroom Instruction
1. Introduce caterpillar, use magnifying glasses to observe, list characteristics; identify color, shape, size body, segments;
2. Expand to study of butterflies and record; recognize and reproduce simple patterns;
3. Observe and identify four stages of life cycle- egg, larva, pupa (chrysalis), adult. See/print life cycle's student activity page at:
http://www.enchantedlearning.com/subjects/butterfly/label/lifecycle/label.shtml

Printed products
A. Page -Using Microsoft word, students will create a page describing the stages of the insect's life cycle- egg, larva, pupa and adult, and add clip art.

1. Identify and research selected species.
2. Record on paper.
3. Open MS Word and create a new document.
4. Create a page describing the characteristics of the butterfly, life cycle and its habitat.
5. Illustrate page with clip art.
6. Save the document (File>Save>U:My Stuff).

B. Graph - Use information from science lessons.
Using Microsoft Excel or Microsoft Works/Spreadsheet, or other graphing program, students will make a bar graph showing the number of butterflies that hatch from the chrysalis (cocoons) on different days of the week. i.e. (Monday -- 6 hatched; Tuesday 2 hatched; Wed. 8 hatched; etc.).

IIII. Online
Following classroom instruction, teacher assigns species (butterfly) to pairs of students or small groups.

1.Select one web site (see below), browse/ skim the article for major ideas (types of butterflies, their habitats, migration patterns, and defense mechanisms);
2. Evaluate article for appropriateness and record on life cycles data sheet;
3. Students may be provided with additional URLs to obtain information relating to science and math concepts.
4. Read for information related to topic and record on paper by paraphrasing (not copying).
5. Bookmark site or add to Favorites folder.
6. Record information source and the URL (web site) on paper for bibliography.
7. Use a story board template to plan your presentation.
8. Close the web browser and go off line.

IV. Multimedia project (May be used with printed materials or online research.)
Students will use PowerPoint to make a project showing different types of butterflies.

1. Identify and research selected species.
2. Introduce story board to students.
3. Write researched information from data sheet onto story board.
4. Bring your completed story board worksheet to the computer. (create at least one informational slide created from notes taken in previous session)
5. Introduce PowerPoint to students.
6. Open the presentation program.
7. Select PowerPoint slide format.
8. Type researched information onto PowerPoint slide.
9. Add clip art or graphics.
10. Students may create a hyperlink in their presentation to a related web site.
11. Combine slides into presentation.
12. Add title and credit slides.
13. Check spelling and save.
14. Exit the program and log off.
