University of Rochester electrical engineer Mark Bocko has combined his passion for music with his passion for engineering, devising a way to digitally compress music files. Bocko’s team of engineers and musicians at Rochester’s Eastman School of Music are also helping uncover some extraordinarily precise details about just how music is made. With support from the National Science Foundation, they have built a computer model of the clarinet, entirely from real world acoustical measurements taken from human musicians. Measuring such things as how hard the musician is blowing into the instrument and the pressure the musician applies to the reed, they have modeled the way music is made.

At first, the back room of plant physiologist Edgar Spalding's lab at the University of Wisconsin-Madison might be mistaken for an alien space ship set straight out of a Hollywood movie. It's a room bathed in low-red light with camera lenses pointing at strange looking entities encased in Petri dishes. A closer inspection reveals the Petri dishes contain nothing alien at all, but rather very down-to-earth corn seedlings. They're grown in red light for optimal growth. They're just one of the plants featured in thousands of time-lapse movies Spalding has created over the past five years. The goal is to figure out how to grow crops optimally.
Engineers are motivated to improve our quality of life, and they typically develop new products to achieve this goal. They use several steps in developing new products: design phase, testing phase, and production and maintenance phase. During the design phase, engineers specify the functional requirements of the product. They also produce a prototype to evaluate its overall effectiveness. They also consider cost, reliability, and safety. During the last two phases, engineers determine if any failures of the components are likely and where they occur. In these processes, engineers use computers to create designs, analyze functionality, and simulate how a machine, structure, or system operates.
Scientist William Rowan is renowned for his research on the dark-eyed junco. Before Rowan, it was unknown what environmental cues animals used to time the seasonal changes in their biology. Through a groundbreaking experiment with the junco, Rowan discovered the physiological reaction of organisms to the length of day or night. Shot as an historical re-enactment, this segment provides a glimpse into the history and human dimensions of scientific research and reveals one of the first studies that made juncos well-known to biologists. Part of Ordinary Extraordinary Junco (Chapter 1).
Researchers at the state-of-the-art Structural Engineering and Materials Laboratory at the Georgia Institute of Technology are using a full-scale model building to test new ways to protect structures from earthquakes and potentially save lives. The three-story concrete building is based on designs common through much of the 20th century. It has been subjected to round after round of simulated temblors to test if materials such as carbon fiber or new shape-memory alloys can be used to reinforce the structure so it would remain standing in moderate to strong earthquakes. With support from the National Science Foundation, structural engineer Reginald DesRoches and his team have developed a series of retrofits of varying cost and intrusiveness to give building owners in quake-prone areas a range of choices for hardening their property.
Stuart Rowan, a professor at Case Western Reserve University, has created polymers that are able to self-heal when heat is applied using a special light. Part of the Fast Draw Series.
Lorenzo Prendini spends his time looking for new species of scorpions and researching their ancestries. He also studies how venomous species might benefit the medical community. Josh Landis and Mitch Butler follow Lorenzo out into the field to study scorpions and talk with him about his experiences through this research. Part of the Fast Draw Series.
Breadmaking is both a science and an art. Learn about the science of fermentation and discover how the process of making sourdough bread is unique.
Presents general information about the scientific method and identifies its steps. Gives simple examples of how it is used in daily life and restates the steps several times.
Uses practical examples to help students understand and use the components of the scientific method. Concepts and terminology: hypothesis, experiment, measuring, data, analysis, and conclusion.
Demonstrates how to observe and record scientific observations. Concepts and terminology: observation, data, recording, data table, tools, safety, measuring, and graphs.
New research reveals why the saber-tooth tiger needed such large teeth.
Students learn how to differentiate mixtures, solutions, elements, and compounds. Additional concepts and terminology discussed include: element, pure substance, properties, atoms, molecule, compounds, types of mixtures, suspension, colloid, and alloy.
Down in the village square, everyone is scratching themselves. What exactly happened last night after the rain? Hanna and Olli lead the investigation with some help from Suzie the spider. Part of the "My Little Planet" series.
The concepts of reliability and validity are demonstrated through a simple exercise. Students learn the importance of consistency and interpreting data in a relevant manner when conducting experiments.
Two teenagers apply the scientific method to solving everyday problems: explaining a burned-out light bulb and exploring the possibility of falling toast landing jelly-side down. Defines terms and offers other examples to demonstrate the scientific method in use.
A cure for Motherboard might be hidden in the windiest spot in the Northern Frontier, and the kids must figure out how to measure wind speed to find the cure. Part of the "Cyberchase" series.
What happens when the world of art intersects with the world of science? Alberto Rojo, musician and physicist, discusses the role of a researcher in both disciplines. In this episode, he shows parallels between creating music and researching science. He tells us how artists and scientists share similar methods of gathering knowledge and researching ideas.
Explains where and when the scientific method originated and describes each of the five steps that comprise the method. Each step is broken down and explained through a series of scientific experiments.
