Students are introduced to our Sun as they explore its composition, what is happening inside it, its relationship to our planet (our energy source), and the ways engineers help us learn about it.
Our Big Blue Marble
Students are introduced to the fabulous planet on which they live. Even though we spend our entire lives on Earth, we still do not always understand how it fits into the rest of the solar system. Students learn about the Earth’s position in the solar system and what makes it unique. They learn how engineers study human interactions with the Earth and design technologies and systems to monitor, use and care for our planet’s resources wisely to preserve life on Earth.
Cutting Through Soil
Students pretend they are agricultural engineers during the colonial period and design a miniature plow that will cut through a “field” of soil. Students are introduced to the engineering design process and learn of several famous historical figures who contributed to the design of the plow.
Photosynthesis – Life’s Primary Energy Source
This lesson covers the process of photosynthesis and the related plant cell functions of transpiration and cellular respiration. Students will learn how engineers can use the natural process of photosynthesis as an exemplary model of a complex — yet efficient — process for converting solar energy to chemical energy or distributing water throughout a system.
Students explore the many different ways that engineers provide natural lighting to interior spaces. They analyze various methods of daylighting by constructing model houses from foam core board and simulating the sun with a desk lamp. Teams design a daylighting system for their model houses based on their observations and calculations of the optimal use of available sunlight to their structure.
Engineering: Simple Machines
Simple machines are devices with few or no moving parts that make work easier. Students are introduced to the six types of simple machines — the wedge, wheel and axle, lever, inclined plane, screw, and pulley — in the context of the construction of a pyramid, gaining high-level insights into tools that have been used since ancient times and are still in use today. In two hands-on activities, students begin their own pyramid design by performing materials calculations, and evaluating and sele
The Growling Stomach
In this lesson, the students will investigate what types of plants and insects they could eat to survive in the Amazon. They will research various plants and/or insects and identify characteristics that make them edible or useful for the trip. The students will create posters and present their findings to the class.
U.S. says Gaddafi weakened but not defeated
U.S. military officials say Gaddafi is not close to a military breaking point even though coalition strikes have seriously degraded his fighting power. Deborah Lutterbeck reports.
Eureka! Episode 10 - Potential Energy vs Kinetic Energy
A rock teetering on the edge of a cliff is shown to have potential energy - the energy of position. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in simple and well illustrated way. Good for students of any elementary school level. (04:51)
Kinetic Energy and Work
Animated billiard balls help demonstrate kinetic energy - the energy of motion. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in simple and well illustrated way. Other key vocabulary words addresses in this video include: work, force, mass, acceleration, newtons, joules, innertia, gravity, movement, speed, distance, and transfer of energy. (04:49)
Compiler Confidential | GoingNative 2013 Modern CPU and instruction set architecture improvements are critical to the performance of software, but it's the compiler that can make your code sing. Come learn how compiler optimizations are enabling the next generation of native code performance. This talk will go deep into the guts of the Visual C++ compiler optimizer, focusing on compiler optimizations from the point of a view of modern CPUs. Down to the metal we go!

5.1 Pollution and loss of biodiversity
To be able to understand the importance of the environment for our health, we need to know a little about the interdependence between environment and humankind. This unit will look at interactions between plants, animals and the physical and chemical environment, as well as considering ways in which humans have altered, and are altering this environment. These changes have health implications that are not always immediately obvious. Frequently, we initiate changes that are going to have their ef
Lecture 5b: Functional Analysis - Infinite products and Tychonoff's theorem
The sixth class in Dr Joel Feinstein's Functional Analysis module is a revision of finite products of topological spaces. Further module materials are available for download from The University of Nottingham open courseware site: http://unow.nottingham.ac.uk/resources/resource.aspx?hid=bd32d53b-3c12-ac19-176b-d9e112731951 and on iTunes U: http://itunesu.nottingham.ac.uk/albums/64.rss Dr Feinstein's blog may be viewed at: http://explainingmaths.wordpress.com Dr Joel Feinstein is an Associate Pro
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)
C21: Physics Teaching for the 21st Century
Physics Teaching for the 21st Century is a resource for teachers who are interested in teaching physics concepts in real world contexts. The great problems of the 20th century were solved by a few incredibly smart people. The great problems of the 21st century will have to be solved by billions of moderately smart people. This is where teachers come in... In this website you will find: * articles that clearly explain the physics concepts in a real world context * take-home experiments that ca
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.
Molecular Expressions Microscopy Primer: Physics of Light and Color - Lenses and Geometrical Optics
This webpage contains a series of java applets which illustrate the physics of image formation and the effect of aberrations on image distortion. As this webpage is part of a larger website on microscopy and imaging, there is a manu on the left-hand side of the webpage that guide the user to primers on microscope operation, confocal microscopy, digital imaging, and photomicrography.
RSC.org: Mass Spectrometry
This video, distributed on YouTube by the Royal Society of Chemistry is on the basic principles of mass spectrometry, using a magnetic sector instrument to demonstrate how specific m/z ratios can be selected. The theory and operation of MS, including the chemistry of ionization and fragmentation is described at an introductory level. There\'s also an excellent example of the use of high resolution MS to differentiate between nominal mass and actual mass. The video does a very good job of explain
This webpage, part of a larger project \"Understanding Chemistry\", provides a solid introduction to UV-vis spectroscopy suitable for use in introductory chemistry and introductory analytical chemistry courses. The UV-vis pages discuss UV-vis light, absorption, Beer\'s law, the double-beam spectrometer, and introduce some standard applications of UV-vis spectroscopy. Explication is clear and thoughtful. Judicious and effective use of graphics. Site is easy to navigate, and the links work.
