This USGS site explains what an aquifer is and defines the different types of aquifers based on six principal lithologies; sandstone, carbonate, sandstone-carbonate, igneous and metamorphic, sand and gravel, and other rock types. The site features maps and descriptions of the major aquifers in the United States as well as general information about groundwater occurrence and quality. The site also provides links to additional maps and data about specific aquifers across the nation.
Learn about velocity and acceleration vectors. Move the ball with the mouse or let the simulation move the ball in four types of motion (two types of linear, simple harmonic, circle). See the velocity and acceleration vectors change as the ball moves.
Entrepreneurship is the "pursuit of opportunity without regard to resources currently controlled". This definition implies that successful entrepreneurs are able to utilize resources that they do not personally own or control. They must go beyond opportunity recognition and the creation of great business concepts and find creative methods for acquiring a variety of resources. Especially critical is their ability to find money for venture start-up and then to obtain money for ongoing venture grow

Emerging Enterprise Consulting (Syracuse University)
Entrepreneurship is the key to the American dream. Sustainable growth and an enhanced standard of living for all Americans are dependent on a vibrant, growing entrepreneurial sector. There is a need for entrepreneurs with creative business concepts and the courage to turn these concepts into sustainable enterprises that create jobs for citizens and create value for customers. There is a key difference, however, between starting a business and growing one. The majority of small businesses fail to
Nuclear Energy: France vs. the U.S.
This lesson presents a comparison of the outlook for energy independence between the United States and France. Topics include the average per capita energy usage between the two countries and differences in types of energy usage.
6.7 Modelling with objects
Enterprise systems are software applications that automate and integrate all many of the key business processes of an organisation. With some understanding of software development, you will learn about current development practices for this type of system and develop relevant skills to apply them to real-world problems. You will develop core skills in object-oriented analysis and design, allowing you to develop software that is fit for purpose, reusable and amenable to change.
A Grid-Based Approach for Processing Group Activity Log Files
The information collected regarding group activity in a collaborative learning environment requires classifying, structuring and processing. The aim is to process this information in order to extract, reveal and provide students and tutors with valuable knowledge, awareness and feedback in order to successfully perform the collaborative learning activity. However, the large amount of information generated during online group activity may be timeconsuming to process and, hence, can hinder the rea
Your Beating Heart
There are three lessons in this group. The first two provide students with the opportunity to learn about the circulatory system and conduct an experiment where they take their pulses after different types of activity. During the third lesson, a pediatrician explains how she checks a patient's heart and the ways that a healthy lifestyle (food and exercise) can keep students' hearts healthy.
Internet Scout Project
The companion Web site to the NOVA program Life's Greatest Miracle, which PBS will re-broadcast on February 26th, is a great site for anyone interested in human pregnancy and fetal development. With wide-ranging information, this Web site is likely to appeal to many different audiences; users can even choose to view the entire program online. Those users interested mainly in the science of human development will enjoy How Cells Divide and How Sex is Determined. Those more interested in learning
Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,The video shows the student describing how rocks can come in many different sizes such as grains of sand and large boulders. The interviewer further probes to find out how the student thinks that something as small as a grain of sand can be a rock.
Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,In this segment the interviewer is trying to find out if the student has prior knowledge about types of rocks by asking her about the stripes on the rock. The student uses the word "metamorphic" and goes on to explain what a metamorphic rock is. The interviewer probes further by asking her why rocks get pressed together and where the stripes may have come from. He then shows her a picture to see if she can connec
Essential Science for Teachers: Physical Science: Session 2. The Particle Nature of Matter: Solids,
In-depth interviews with children that uncover their ideas about the topic at hand.,In this segment the student is describing how all atoms are the same. He begins by drawing his own mental model of an atom and explaining that all atoms are made up of protons, neutrons, and electrons. He says the air atom is the same as the aluminum foil atom. He goes on to describe other things that are made up of the same particles. The interviewer probes further to find out if atoms of different substances ar
Covers different types of adaptive filters and their implementations. In depth analysis is done of the Wiener Filter algorithm and the LMS algorithm.
Introduction to Stoichiometry
Our on-line Chemistry course covers stoichiometry and demonstrates our scenario based approach to teaching chemistry. Traditional courses tend to follow a bottom-up approach to learning chemistry. This traditional approach teaches abstract concepts and tools before discussing their practical application, which results in students learning bits of unconnected knowledge that are rarely usable let alone memorable. In our approach, scenarios are used both to motivate the material and provide a frame
Risk Management for Enterprises and Individuals
This book is intended for the Risk Management and Insurance course where Risk Management is emphasized. When we think of large risks, we often think in terms of natural hazards such as hurricanes, earthquakes or tornadoes Perhaps man-made disasters come to mind such as the terrorist attacks in the U.S. on September 11, 2001. Typically we have overlooked financial crises, such as the credit crisis of 2008. However, these types of man-made disasters have the potential to devastate the global mark
Strong as the Weakest Link
To introduce the two types of stress that materials undergo — compression and tension — students examine compressive and tensile forces and learn about bridges and skyscrapers. They construct their own building structure using marshmallows and spaghetti to see which structure can hold the most weight. In an associated literacy activity, students explore the psychological concepts of stress and stress management, and complete a writing activity.
At Ocean's Edge: Coastal Change in Southwest Washington
As a result of coastal erosion problems in southwest Washington state, a study was commissioned to examine the coastal evolution, processes, geology, and hazards of the area. This program previews the five-year cooperative SW Washington Coastal Erosion Study, which detailed the need for data and models that predict coastal change, allowing coastal communities to make more informed decisions about land use.
