In this video profile, students meet mechanical engineer Nate Ball, who explains his big invention – a search-and-rescue rope-climbing device. He describes the process used to design, build, and test the “Ascender” and discusses the role of failure. http://to.pbs.org/1fh2dmr
<p>Meet mechanical engineer and inventor Nate Ball in this video profile from <em>The Secret Life of Scientists & Engineers</em>. Ball explains how an idea for a design competition project led to his big invention: a rope-climbing device named the Atlas Power Ascender that is used in search-and-rescue operations. He describes the process used to design, build, and test the Ascender and discusses the role of failure, which is not only common in en...

Are your students curious about how things work? Do they like to come up with new ways of doing things? Then they have what it takes to be an inventor! Start the process with this Martha Speaks activity: http://to.pbs.org/1vSweAJ
<p>In this MARTHA SPEAKS interactive story, learn about how new devices are developed. After inventors come up with an idea to improve life, they need to try it out, make changes as needed, and then work to perfect it. When used as a part of Martha’s True Stories Buddies Program, buddy pairs engage with the interactive story, then talk and create an Inventor’s Workshop to describe their idea for a new invention that will solve an everyday problem...

What does measuring oxygen consumption tell you about the fitness of an individual? Share this NOVA video with your class, and explain to them the effect of exercise on the cardiovascular system and one measure used to gauge aerobic fitness – VO2 max. http://to.pbs.org/1CTc3QR
<p>This video segment adapted from <em>NOVA</em> describes the effect of exercise on the body and defines one measure used to gauge aerobic fitness. VO<sub>2</sub> max (maximal volume of oxygen uptake) is a measurement of how well the body gets and consumes the oxygen that muscles need in order to sustain activity. Learn how the entire cardiovascular system benefits from exercise and how the body's response to the demands of physical activity is ...

How did Henry Ford use a wage increase to address challenges facing his auto company? And how did that decision lead to societal changes that went form a focus on production alone to production AND consumption? Students find out in this clip from American Experience. http://to.pbs.org/1fh3rOz
<p>Discover how Henry Ford used an increase in wages to address challenges facing his automobile company in this clip from <em>American Experience</em>. By more than doubling wages and creating "worker shareholders," Ford was able to both reduce assembly line turnover and create an expanded customer base for his Model T automobile. The policy played a major role in the transformation of the United States during the early 20th century from a socie...

History is rich with inventions. In this interactive, student scroll through a timeline of famous – and forgotten – inventions, from the submarine and space shuttle to false teeth and frozen food: http://to.pbs.org/1HqjyzM
<p>History is rich with inventions. Some innovations failed, some spawned new ideas, and some are still with us a hundred or more years later. This interactive timeline, from the <em>AMERICAN EXPERIENCE</em> website, outlines and describes some of the important technological innovations from 1750 to 1990.</p>

When designing an aircraft to avoid both human and electronic detection, engineers often must make performance concessions such as speed. This interactive lesson details the design process those engineers use: http://to.pbs.org/1gstTp8
<p>This interactive activity from the NOVA details what aeronautical engineers must consider when designing an aircraft to avoid both human and electronic detection. It acknowledges that in the engineering design process there are necessary performance tradeoffs to achieving stealth, but in many cases the ability to evade enemy radar detection and missile defense systems is more valuable than speed.</p>

Using satellite data to explore the deep ocean, take a look at images from NASA showing changes in the temperature and color of the surface of the ocean. http://to.pbs.org/1J8FTD4
<p>In this video excerpt from NOVA: “Earth From Space,” learn how hydrothermal vents produce mineral-rich water that nourishes organisms. Underwater footage shows mineral-laden water spewing from hydrothermal vents, which nourishes deep-sea ecosystems as well as life near the surface. The nutrients from vents circulate through the oceans over thousands of years and contribute to phytoplankton blooms. Satellite images show changes in the temperatu...

A little exercise goes a long way in preventing disease. As a lesson in health and science, teach your class the benefits of physical activity, down to the cellular level. http://to.pbs.org/1JOrfUn
<p>Middle school students discover the importance of exercise in maintaining fitness and preventing disease. Human fitness - physical strength, stamina, and power - is totally dependent upon the health and functioning of the collection of mitochondria located inside each of the 32 trillion cells in the body.</p>
