Nonlinear physics is a catch-all term for the study of the dynamics of driven, open, non-equilibrium systems. Our group is mainly concerned with the phenomenon of pattern formation. When a nonlinear, dissipative system ( that is, one with friction ) is driven hard enough, it will often undergo a symmetry-breaking instability which takes it to a regular pattern state. The pattern is a dynamical state sustained by the driving forces which can have a high degree of periodic order and symmetry, even
Mass Wasting/Landslide Animations
This site features Flash animations, MPEG simulations, and Real Media video clips that illustrate subsurface processes and consequences of mass wasting and landslide movement. Visualizations of slumps, flows, falls, and translational and rotational slides show bedrock failure and displacement and subsequent building damage and scarp, flowage zone, and toe formation. These resources portray a variety of modeled and real environments and are suitable for use in lectures, labs, or other teaching ac
Cause of Seasons Animations
This site features Flash, QuickTime, and GIF animations that illustrate the cause of seasons, how seasons impact the sun's apparent path across the Earth's sky, the subsolar point, and the circle of illumination. The animations can be paused and rewound to stress important points. These resources are suitable for use in lectures, labs, or other teaching activities.
Petrography and Petrology
This site is the home page for the petrography and petrology class at Brock University. The site presents general information about igneous petrology, nomenclature and classification information, modal and normative analysis, and the chemistry of igneous rocks. Further topics discussed include fractionation, hybridization and assimilation, and fractional crystallization, as well as types of metamorphism, compositional groups, and Barrovian metamorphism. The information is presented as a sequence
provides a map linked to nearly 60 national park sites and resources that emphasize the role of African Americans in the development of American culture, heritage, and history. Each link describes the importance of that park or resource to African American history.
Show Me a Picture and I'll Tell You a Story: Web Photo Journals
Students analyze and evaluate "photo journal" web sites, then create their own Web-based photo journal.
Single-Celled Organisms Unit
This Project Oceanography lesson plan (PDF) explores the symbiotic relationships of single-celled organisms. In this activity, students will compare and contrast three types of symbiotic relationships, describe the relationship between zooxanthellae (a dinoflagellate) and coral, and explain the effects of nitrogen-fixing bacteria on their symbiotic partners. It begins with an introduction to symbiotic relationships, the dinoflagellate/coral system, and cyanobacteria, and then features an interac
This Web site from the National Center for Biotechnology Information (NCBI) offers a set of detailed tutorials to help users make full use of NCBI's bioinformatics tools. The tutorials, which target both new and veteran users, cover NCBI's BLAST and PSI-BLAST, Entrez data retrieval system, Cn3D molecular structure software, and more. Additionally, the Science Primer tutorial offers a "basic introduction to the science underlying NCBI resources" geared more toward the general reader.
What good is Beowulf?
High school students can follow the English language's evolution in Beowulf and The Canterbury Tales, and they can focus on words and their meaning as they compare translations.
Two paths to knowledge
For students who always finish their class work early or want more information than you have time to give, try curriculum compacting.
Play with purpose
Electronic whiteboards make the internet an active communication vehicle of engagement and learning.
Understanding and using fonts
Serifs, sans serifs, and when to use them.
Superfund in science class
Four Web-based activities let students identify Superfund sites, define hazardous waste, see how aquifers work, and explore cleanup solutions.
Contemporary life in Vietnam
Photographs and text describe contemporary life in Vietnam and the impact of economic and social reforms since the 1980s.
Not your mother's math teacher
North Carolina's 2001-2002 Teacher of the Year, Carmen Wilson, talks about real-world math and teachers' roles as professionals.

Central and Eastern Europe: Peace Corps
provides lessons about stories, letters, and folk tales from experiences of Peace Corps volunteers in rural and urban areas of Central and Eastern Europe. Topics include folk tales, Macedonia, Romania, Bulgaria, fear of certain numbers, transition from a state-controlled system to a democracy, school in Ukraine, the importance of speaking another language, storks and cultural icons, and family traditions as macrocosms of larger cultures.
Kõrv loodusesse - loodushelid ja helid looduses
Loodushelid ja helid looduses. Veebilehed info ja illustratsioonidega vastavatest liikidest, võimalik kuulata helindeid. Kõrv loodusesse kasutab kahte erinevat kokkusurutud helifaili formaati: mp3 ja real audio. Üldjuhul võimaldab mp3-formaat paremat kvaliteeti, kuid faili maht on suur. Real audio on väiksema failimahuga, kuid sellega kaasneb kehvem kvaliteet. Aeglase ühenduse korral on seetõttu otstarbekam valida real audio helindid. Kiirema ühenduse korral tasub kuulata parema kvalitee

Identity in question
Why is identity important and how are identities formed? This unit looks at the many different ways in which identity can be categorised. By examining the requirements of the state, how a child views gender, and the importance of race or place of birth, you will start to understand how each individual can have more than one identity.
