NCBI More Information: Similarity
This page summarizes the basic concept and vocabulary of sequence similarity searching. It is included for those new to the field who may not appreciate the importance of this technique in biology, who lack the vocabulary to understand the BLAST guide and tutorial or who require a basic rather than a sophisticated understanding of the methods involved. Sections include introduction, premise, terms, general approach, the BLAST algorithm, quantification, gaps, significance, and databases. Users ca
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.
Hunting Bears with a Microscope
In this online activity, students use lichens and tardigrades (water bears) to investigate their use as bioindicators of key air pollutants. When lichens are exposed to some kinds of air pollutants, especially to sulfur dioxide, the lichens are injured and die. The lichen coverage in a specified area should be a good indicator of the level of air quality. The diversity of the tardigrade species on the lichens will be used to develop another level for bioindication of air quality. Sections of thi
Creatures that "glow" in the night
This Wisconsin Center for Environmental Education activity (PDF) encourages students to practice experimental design and scientific writing through the study of bioluminescence. Students observe and experiment with bioluminescent dinoflagellates (Pyrocystis fusiformis), learning how and why they produce light. The activity includes information for teacher preparation, an introduction to bioluminescence, defined vocabulary terms, a list of necessary materials, procedure, assessment questions, and
Cephalopod Lesson Plans
This collection of lesson plans, created by the Bermuda Biological Station for Research, highlights color change in cephalopods. This page provides links to each lesson plan, which are in PDF format and feature an informative, image-rich introduction followed by a hands-on laboratory activity. The lesson plans highlight cephalopod color change, vision, light quality, and light quantity.
Imaging: Digital Images
Video: Imaging: Digital Images Episode 9 (of a 25-part series) This Nortel LearniT tutorial familiarizes students with Digital Images. Digital Images has changed the photography industry. There are many ways to change the images.
ReSciPE Workshops: Scientific Inquiry in the K-12 Classroom
This half-day workshop was developed especially for scientists and science educators interested in contributing to K-16 science education. Workshop activities provide participants with an overview of the research base behind inquiry teaching and learning, an introduction to national standards for inquiry-based K-12 science education, and some hands-on examples of how inquiry can look in the classroom. This workshop is sponsored by the Cooperative Institute for Research in Environmental Sciences

This Dynamic Earth: The Story of Plate Tectonics
In the early 1960s, the emergence of the theory of plate tectonics started a revolution in the earth sciences. Since then, scientists have verified and refined this theory, and now have a much better understanding of how our planet has been shaped by plate-tectonic processes. We now know that, directly or indirectly, plate tectonics influences nearly all geologic processes, past and present. Indeed, the notion that the entire Earth's surface is continually shifting has profoundly changed the way

Campfire Stories with George Catlin: An Encounter of Two Cultures
In this lesson students will learn about the varying attitudes and definitions of land ownership held by Native and European Americans by studying a variety of primary documents from the nineteenth century. They will learn about how various treaties—the Homestead Act and the Dawes Act—affected both Native and European Americans. Students will discuss these issues in the form of a debate, and will also write journal entries.
Rocket Car on an Inclined Plane Model
The EJS Rocket Car on an Inclined Plane model displays a car on an inclined plane. When the car reaches the bottom of the incline, it can be set to bounce (elastic collision) with the stop attached to the bottom of the incline. The car consists of the car body, two rotating front wheels, and two rotating rear wheels. The incline angle (in radians) can be changed via a textbox and the rocketâ€™s thrust can be changed via a slider. In addition the car can be dragged to its initial position. A
3.1 The origins of domesticated dogs Archaeologists and biologists agree that dogs (Canis familiaris) were the first species to become domesticated. Francis Galton, Darwin's younger cousin, suggested at the end of the 19th century that domestication began when humans captured and raised wolf puppies. The resulting adults ate scraps of human food, assisted in hunting and acted as guard dogs around camps. Among the evidence in support of this hypothesis is the observation that tribal people all over the world take wild anim

Fossil Fuels: Coal
This lesson provides an introduction to the use of coal as an energy source. Topics include the history of coal usage, applications of coal as an energy source, and major suppliers of coal (the United States).
Hey, Mr. Producer!
It's not that uncommon for secondary school students to study the ups and downs of the stock market, but in this lesson, students will examine the economic roller coaster involved in the production of a Broadway musical. As an introduction to the lesson, students will read a series of online articles to investigate the similarities and differences between nonprofit theater production and Broadway, or commercial, theater production. They will view excerpts from the PBS series BROADWAY: THE AMERIC
