The new companion Web site to the PBS special Fireworks! (which premiered January 29, 2002) contains excellent information for anyone wanting to learn more about the science behind the controlled chaos of pyrotechnics. The interactive site features a section called Name That Shell, where you can view movies of fireworks and compare them to different varieties shown in photographs. Using a Flash presentation, the Anatomy of a Firework explains what happens from ignition to explosion of a firework

Since the concept of permaculture was introduced by biogeographer Bill Mollison in the 1970s, it has attracted increasing interest from agriculturalists, designers, ecologists, and others. The Permaculture Research Institute (PRI) describes permaculture as "the harmonious integration of landscape and people providing their food, energy, shelter, and other material and non-material needs in a sustainable way. It is also the conscious design and maintenance of agriculturally productive ecosystems

This remarkable Web site contains descriptions and animations of nineteen different kinds of engines. Engine types include internal combustion, steam, and sterling engines, and each page shows how the piston, crankshaft, and other components move together to generate power. The animations demonstrate the processes of intake, compression, and exhaust. Some of the featured engines have more detailed descriptions than others, and oftentimes, a brief account of the engine's history is included. One

Détermination automatique des théorèmes-en-acte des élèves en algèbre. Le cas des équations e
Dans cet article, nous sommes intéressés à la détermination automatique de théorèmes-en-acte en algèbre. Ces théorèmes-en-acte ont été construits de façon abstraite, puis nous avons cherché à automatiser le mécanisme de leur diagnostic. Pour cela, nous avons utilisé le logiciel Aplusix comme support des productions des élèves qui permet d'enregistrer toutes les actions des élèves. Une base de règles correctes et erronées a été mise en place et un interpréteur de règles
Formalisation d'annotations produites par des apprenants
L'objet de cet article est la description d'une formalisation computable des annotations produites par des apprenants, représentée par une ontologie. Cette formalisation explicite la sémantique des annotations grâce à des attributs auxquels le lecteur devrait donner une valeur. Elle contient également les valeurs possibles de ces attributs. L'intérêt d'une telle formalisation est de couvrir toutes les annotations produites par des apprenants, et d'expliciter tout ce qui constitue leur se
Section Hands Working on the Railroad

Private Universe Project in Mathematics: Workshop 4: Thinking Like a Mathematician
What does a mathematician do? What does it mean to think like a mathematician? This program parallels what a mathematician does in real life with the creative thinking of students.,How a Mathematician Approaches Problems - Fern Hunt, a mathematician at the National Institute for Standards and Technology, is seen as she collaborates with colleagues to solve difficult technical problems. Using the metaphor of the childrens game Towers of Hanoi, she explains her approach to solving problems. 15
Private Universe Project in Mathematics: Workshop 3. Inventing Notations
We learn how to foster and appreciate students notations for their richness and creativity. We also look at some of the possibilities that early work in creating notation systems might open up for students as they move on toward algebra.,15 min. Pizzas in the Classroom In Englewood, New Jersey, Blanche Young, who attended the summer workshop, tries out one of the problems with her fourth-grade students. Later, she meets with Arthur Powell to discuss the lesson. 5 min. New Brunswick, New Jersey
The impact of simulator-based instruction on the diagramming of the interaction of light and matter
We examine the conceptual development resulting from an instructional experiment with an interactive learning environment in geometrical optics for introductory high school physics. How did teaching-learning processes come to change the ways in which students depicted various everyday optical situations in paper and pencil graphical representations? We view conceptual development as a process resulting in part from increasingly aligning one's practices to a target community by means of participa
To Kill A Mockingbird role-play: A Maycomb pig pickin'
Somewhere near the middle of reading the novel, students start to become confused about characters. This fun role-play activity works especially well just after Chapter 21 and allows students to get to know characters beyond Jem and Scout. It also can be a springboard into further discussions of point of view, theme, and stereotypes.
6.2 A rational-economic perspective on risk A rational-economic perspective generally represents risk as a combination of the expected magnitude of a gain or loss, combined with some probability distribution of anticipated outcomes. Economic ideas of risk behaviour are founded largely on expected utility theory. Expected utility theory predicts that investors will always be risk averse. The shape of the utility curve (utility plotted against increasing wealth) is such that utility increases with wealth, but at a declining rate. This is

Students will understand the life cycle of the butterfly and create various art activities that would model metamorphosis.
Using RAFT to determine how to write an informational essay
Students will use RAFT as a tool to determine how to write an informational essay. They will also design a graphic organizer for the assignment as well as compose a rough draft. This is the second lesson in a series of three based on the LEARN NC 9th grade writing exemplars.
Twas the night before Christmas: Retelling through thinking maps
After reading and discussing "Twas the Night Before Christmas," students will work together to create a Flow Map. Each student will then use the map they created individually to retell the story in his/her own words.
Good beginnings hook readers and make them want to continue reading. Students will learn the features of good beginnings by reading the beginnings of several narrative picturebooks, and then writing good beginnings for their own narratives.
This lesson will begin a unit on fairy tales for young learners. It will begin with assessing what first graders know about fairy tales. Children will learn about the original version of "The Three Little Pigs". There is a second lesson linked to this lesson - Fairy Tales - Another Point of View. This second lesson presents another point of view of the original version of the fairy tale.
Creating found poetry from picture books
Students select and read a picture book and afterwards create "found poetry" based on the picture book.
