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.
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
Hurricane Impacts on the U.S. Oil and Natural Gas Markets
This website contains official US energy statistics. The site provides reports summarizing Hurricane Katrina impacts on US oil and gas markets. The site contains shut-in statistics, Gulf oil and natural gas facts, price information, plus links to news, related data and references.
Formulas for functions of two variables
This website features a chart of functions with two variables and the equations for their standard deviation. It is from the Engineering Statistics handbook whose goal is to help scientists and engineers incorporate statistical methods in their work as efficiently as possible. A link to tools and aids for using the handbook is provided.
Chance Welcome Page
This site contains materials to help teach a Chance course, an NSF-sponsored quantitative literacy course that was cooperatively developed by the Chance Team. The goal of Chance is to make students more informed, critical readers of current news stories that use probability and statistics. Links to Chance news, the course, video and audio, teaching aids, and related resources are provided.
IDAHoBiT 2014 at UCL (International Day Against Homophobia, Biphobia & Transphobia)

Amazing Bean Races
Developed for fifth grade and above. Primary biological content area covered:; Plant growth; Seedling morphology; Hypothesis testing; Experimental design; Line graphing; Introductory statistics. Biology In Elementary Schools is a Saint Michael's College student project. The teaching ideas on this page have been found, refined, and developed by students in a college-level course on the teaching of biology at the elementary level. Unless otherwise noted, the lesson plans have been tried at least
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

Electronic Statistics Textbook
This Electronic Statistics Textbook offers training in the understanding and application of statistics. The material was developed at the StatSoft R&D department based on many years of teaching undergraduate and graduate statistics courses and covers a wide variety of applications, including laboratory research (biomedical, agricultural, etc.), business statistics and forecasting, social science statistics and survey research, data mining, engineering and quality control applications, and many o
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
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
Star Library: Regression - Residuals - Why?
As teachers of statistics, we know that residual plots and other diagnostics are important to deciding whether or not linear regression is appropriate for a set of data. Despite talking with our students about this, many students might believe that if the correlation coefficient is strong enough, these diagnostic checks are not important. The data set included in this activity was created to lure students into a situation that looks on the surface to be appropriate for the use of linear regressi
