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.
Exploring Radiometric Dating with Dice
In this lab, students use dice to simulate radioactive decay. Students create a standard decay curve for a fictional element, calculate the half-life of this element, and, using the information their graph, "date" rocks that contain the new element. The use of dice has some advantages over similar exercises because the half-life is not immediately obvious to students and they will need to experimentally determine it. Learning goals, context for use, teaching tips, materials, assessment tips and
2.3 Analysing nucleic acid structures In studying nucleic acid structures, many different experimental approaches can be adopted. In many cases, nucleic acid structures are examined in vitro, under non-physiological conditions, such as after denaturation or chemical synthesis. Nucleic acids within a cell are formed under very specific conditions and the structures that they adopt are influenced not only by the nature of their synthesis (by DNA or RNA polymerases), but by ancillary proteins that influence their folding.

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)
For International Day Against Homophobia, Biphobia & Transphobia 2014 on 17 May, we asked UCL students and staff: What does freedom of expression mean to you? http://dayagainsthomophobia.org Further info: For staff - http://www.ucl.ac.uk/hr/equalities/lgbt/lgbt_group.php For students - http://uclu.org/lgbt-students-at-uclu http://www.ucl.ac.uk/support-pages/lgb
Higher Secondary Mathematics
This course discusses the following concepts: bases and indices; fractional indices; zero and negative indices; exponential equations; definition and laws of logarithms; equations involving logarithms; introduction to surds; linear equations and simultaneous equations.
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
Barrier Scattering model
The EJS Barrier Scattering model shows a quantum mechanical experiment in which an incident wave (particle) traveling from the left is transmitted and reflected from a potential step at x=0. Although the analytic solution to this standard problem is well known, its visualization shows how the incident and reflected waves form an interference pattern and how the incident wave penetrates the classically forbidden region when its energy is less than the barrier height height V0
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
Ejs TPT Ladder Demonstration Model
The EJS TPT Ladder Demonstration model displays the statics and dynamics of a ladder leaning against a wall. The standard (textbook) statement of this problem assumes that there is no frictional force between the wall and the ladder, but a frictional force between the ground and the ladder. In the simulation you can set the initial lean angle and the coefficients of static and kinetic friction between the floor and the ladder.
First Day of School for Middle Schoolers
Lots of talking, but not many insights on how to deal with this situation outside of talking, talking, talking.
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
