What is Mass vs. Weight? We often confuse the terms "mass" and "weight" and use them interchangeably even though they have very different meanings. We can measure weight here on Earth, but not in the microgravity environment on the International Space Station (ISS).

Parade of Games web site was created to provide educators and trainers with easy-to- assemble educational games in a technology- enhanced environment to support key learning points. The site demonstrates the creative use of popular game shows and other familiar games to reinforce learning. "

"children work in teams of three or more students to write and illustrate their own book. The creative process of working in teams helps provide a natural environment to practice editing, teamwork, and the communication skills necessary for future success. All students involved get a sense of pride and accomplishment from submitting the team project. "

"We'll travel to NASA's tool lab and see the equipment we need to build in this challenging environment, from high tech wrenches and hammers"

"The Active Response Gravity Offload System (ARGOS) is designed to simulate reduced gravity environments, such as Lunar, Martian, or microgravity, using an overhead gantry crane system. ARGOS supplies continuous offload of a portion of a subject's weight during dynamic motions such as walking, running, and jumping, to simulate Lunar, Martian or microgravity. "

"NASA's Solar Dynamics Observatory, which is carrying a suite of instruments including a $32 million University of Colorado Boulder package, has provided scientists with new information that energy from some solar flares is stronger and lasts longer than previously thought. See Also: Space & Time * Solar Flare * Sun * Northern Lights Earth & Climate * Geomagnetic Storms * Atmosphere * Energy and the Environment Reference * Solar flare * Solar radiation * Corona * Geomagnetic storm Using SDO's Extreme ultraviolet Variability Experiment, or EVE instrument designed and built at CU-Boulder, scientists have observed that radiation from solar flares sometimes continues for up to five hours beyond the initial minutes of the main phase of a solar flare occurrence."

"With Glean PEMDAS (Please Excuse My Dear Aunt Sally), we present a math learning environment to help teachers extend students' understanding of order of operations concepts. Glean PEMDAS can be used to introduce Order of Operations, and is best applied to critical application of order. Critical application of Order of Operations moves beyond understanding how operations are applied to understanding what happens when operations within an expression are done in a different order. This process adds flexibility to how students think about number and operations, which is important with the introduction of algebra. "

"Lego WeDo. This kit costs US $129.95 and comes with a motor, a motion sensor, a distance sensor and a USB-based hub. The robots built using this kit can be controlled by a variety of software platforms, including Scratch - a free and open source programming environment designed for children. Its actually quite powerful. "

"The Real World Design Challenge (RWDC) is an annual competition that provides high school students, grades 9-12, the opportunity to work on real world engineering challenges in a team environment. Each year, student teams will be asked to address a challenge that confronts our nation's leading industries. Students will utilize professional engineering software to develop their solutions and will also generate presentations that convincingly demonstrate the value of their solutions. The RWDC provides students with opportunities to apply the lessons of the classroom to the technical problems that are being faced in the workplace."

"Plastic is everywhere because plastic is an extremely useful material. It is cheap, strong and lightweight. What's more, it can take on nearly any form or shape, from soft and stretchy to hard and glasslike."

Technologies to harness solar power as a path to low-carbon energy are developing at breakneck speed. This Spotlight looks at how developing countries can best make use of them to benefit the millions of rural poor who still live without electricity?"

"Eleven start-up firms with novel technologies for solving social and environmental problems have set off on a voyage around the world to find new markets where their innovations could improve people's lives. The entrepreneurs will sail to 13 countries, including stops in China, Ghana, India, Mauritius, Morocco, Myanmar, South Africa and Vietnam, as part of the mentor-driven Unreasonable at Sea programme that aims to support a select group of technology companies and their founding members."

"The Earth's climate is a solar powered system. Globally, over the course of the year, the Earth system-land surfaces, oceans, and atmosphere-absorbs an average of about 240 watts of solar power per square meter (one watt is one joule of energy every second). The absorbed sunlight drives photosynthesis, fuels evaporation, melts snow and ice, and warms the Earth system."

"solar array totting, wind turbine holding, rover meant to analyze snow accumulation on the glaciers of Greenland."

"Andrew Wong '12 discusses his focus in engineering, environmental studies, and international studies at Dartmouth."

"I originally stumbled into the environmental engineering major because I could write a good college essay about it (not kidding). Once I actually began researching the major, I decided it was for me. Environmental engineering is a relatively new field that is guaranteed to grow in the future because of an increased demand to go green (aka job openings). I have always loved the outdoors and want to have a job where I can help people and not be stuck behind a desk, which I believe I can find in the environmental engineering field."

"Lesson plans by a team of educators & renewable energy experts. Includes teacher resource guides, reading passages for students, student worksheets Lesson plans are grouped into three age levels designed for elementary school (grades 4 & 5), middle school (grades 6, 7 & 8) & high school."
