Sound Environment Shapers
Students are introduced to the sound environment as an important aspect of a room or building. Several examples of acoustical engineering design for varied environments are presented. Students learn the connections between the science of sound waves and engineering design for sound environments.
Backyard Weather Station
Students use their senses to describe what the weather is doing and predict what it might do next. After gaining a basic understanding of weather patterns, students act as state park engineers and design/build “backyard weather stations” to gather data to make actual weather forecasts.
Water, Water Everywhere
Students learn about floods, discovering that different types of floods occur from different water sources, but primarily from heavy rainfall. While floods occur naturally and have benefits such as creating fertile farmland, students learn that with the increase in human population in flood-prone areas, floods are become increasingly problematic. Both natural and manmade factors contribute to floods. Students learn what makes floods dangerous and what engineers design to predict, control and sur
Drum Roll Please
This lesson gives students hands-on experience making a presentation, and allows them to present and defend their final decision to the class. Students commit to a final decision early in the lesson, then justify that decision. After making their decision they prepare their final presentations.
Deadly blasts and approaching Islamic State militants spark concerns in Baghdad
A series of blasts kill 36 people in and around Baghdad over a two-hour span, and an Islamic State advance on the city spark concern among Iraqis. Nathan Frandino reports.

Objectives for Section 3
This unit will help you to understand the forms of data that are handled by software and look at the various processes that can be applied to the data. These ideas are demonstrated through the use of a supermarket till and illustrate how simple data sets can be manipulated.
Irish banks' 25 bln euro hole?
Ireland is set to reveal up to a 25 billion euro hole in its banks' capital and a radical restructuring of the sector as it releases stress results in a last ditch bid to calm nervous markets.
7.5.1 Evaluate information from different sources Be critically aware of the reliability and quality of information from different sources, taking into account factors such as commercial, political, academic or personal interests that may influence selection, content and presentation. How will you judge the quality of the information you find? You may need to question the validity of statistical information and the way data have been chosen. The size of a survey sample, for example, may be insufficient to support claims of general tren

This video shows step by step how to assembly the percussion kit and how to hold the mallets/sticks and play some first sounds. (07:30)
Mammoth Cave National Park in Kentucky
With over 365 known miles of cave passageways, Mammoth Cave is the world's longest cave. Besides its spectacular size, Mammoth Cave has an almost surreal beauty. Remarkable stories of human history, 350 million-year-old rocks and its fascinating animals adapted to life in the dark make Mammoth Cave a place you must visit. (01:09)
When Computers Changed the World from the Revolution Exhibition
"When Computers Changed the World" is just one of more than 100 videos in the Computer History Museum's new exhibition: "Revolution: the First 2000 Years of Computing." In the span of a single lifetime, computers have gone from large, incredibly expensive and rare devices to small, low-cost, ubiquitous tools that we can't imagine living without. Yet, few people know the history of how this came to be. Revolution: The First 2000 Years of Computing is a rich, multimedia exhibition that traces the
This site is a wonderful resource for undergraduate researchers and their mentors. Topics covered include research nuts and bolts, funding your science, scientific ethics, lab safety, communicating your science and mentoring issues. The site makes good use of case studies, self-study questions and references on each topic.
Analytical Electrochemistry: Potentiometry
This courseware module is structured for either a lecture presentation or self-study tutorial on analytical potentiometry. The level of presentation spans upper high school to college students. Topics include historical background, theory/principles, instrumentation, pH electrodes, experimental examples, and troubleshooting tips.
Teaching Chemical Equilibrium Concepts Using Field-Lab Experiences
This online article describes an inquiry-based experience designed to integrate concepts in water quality and geology for pre-education science students preparing to become teachers at the primary and secondary level. The field and laboratory exercise could be used to effectively introduce equilibrium chemistry in an introductory or environmental chemistry course, and courses for non-majors.
GC Splitless Injection Animation
This site is one in a series of sites with very good animations related to separations. This animation deals specifically with splitless injection in GC. The animations are short (one to two minutes) and can easily be shown in class as part of a lecture. They are extremely helpful in illustrating key components and concepts of chromatographic systems. Users are encouraged to explore the site and the other brief animations as well. Separate links to other simulations by the same company (TRSL) ar
Rice virtual lab in statistics
This site is devoted to statistical tests and demonstrations of their use and was created with the support of the National Science Foundation. One section is a complete reference guide - the online statistics textbook, with detailed descriptions of all things statistical. The second, and most fun section, is simulations/demonstrations section where nearly twenty statistical tests are demonstrated with interactive Applets. Each Applet has clear instructions for use with details on the test demons
Winning friends abroad: can Britain’s cultural power maintain its influence in the modern world?
Sir Martin Davidson KCMG, CEO of the British Council, examines the UK’s soft power capacity.
What is a dynamical system? When we talk about systems in the most general sense, we are talking about anything that takes in a certain number of inputs and produces a certain number of outputs based on those inputs.
2.10 The complex exponential function
Number systems and the rules for combining numbers can be daunting. This unit will help you to understand the detail of rational and real numbers, complex numbers and integers. You will also be introduced to modular arithmetic and the concept of a relation between elements of a set.
