With support from the National Science Foundation, the RoMeLa Lab at Virginia Tech is developing robots to perform a wide variety of tasks and to eventually be able to move and think on their own. The robots in Dennis Hong’s lab climb walls, negotiate bumpy terrain, and type letters.

Stacey Combes, a biomechanist at Harvard University, and her team are using high speed cameras to help them study how dragonflies pull off complicated aerial feats that include hunting and mating in mid-air. They can fly straight up, straight down, hover like helicopters and disappear in a blur. Combes is also exploring the use of dragonflies for mosquito control.
Host Trace Dominguez discusses the current trends in the number of hurricanes and their strength. He examines weather data collected since 1880 coupled with new models created by NASA. According to the data and weather models, hurricanes are becoming more intense.
In contrast to the peaceful wildlands featured in the prior segments, the urban campus of the University of California-San Diego (UCSD) seems like an unlikely place to find field biologists studying juncos. But in the early 1980s, some juncos decided to make this atypical urban and coastal habitat their year-round home. Since then, scientists have documented a remarkable array of changes in the physical traits, behaviors, and physiology of the colonist population of juncos at UCSD when compared to juncos from the nearby native range. Part of Ordinary Extraordinary Junco (Chapter 6).
In this episode, host Dianna Cowern investigates the biomechanics of butts. What activates one's butt muscles more, running or squatting? How effective are bridges as a workout? How much can individuals change the shape of their bodies with exercise? Dianna and Dr. Rowley conduct various experiments to answer these questions about anatomy and physiology. Part of the "Physics Girl" series.
Third in the series of three productions designed to let students learn by doing, guiding them through the science and history behind the Wright Brothers' invention of powered flight. This third component contains the same "how to" segments from the second in the series (13692) and parts of the history and scientific concepts from the first in the series (13691). However, it also provides greater ease and flexibility in locating, reviewing, and pausing in and between segments than the other two productions in the series. Good for sharing with students to aid them as they build and experiment with kites, gliders, and rubber-band-powered planes.
Are reusable water bottles better for the environment? Host Trace Dominquez explores the intensive manufacturing process of reusable bottles as well as their over production and how this impacts the environment. Part of the "Uno Dos of Trace" series. Please note this title contains potentially offensive language.
Why do we gesture? What role do simple hand movements play in some of the most fundamental aspects of language? Susan Goldin-Meadow has dedicated her career to asking, and answering, those big questions. In her lab at the University of Chicago, she studies gesture’s role in cognition, development, and the acquisition of verbal language. Part of the Scientists and Engineers On Sofas Series.
Host Trace Dominguez sets out to discover how elements are formed. He elicits help from Dr. Ian O'Neill. During their conversation, they discuss the role that stars play in creating heavy elements throughout the universe.
Dr. Kimberly Dodge became deaf at the age of eight. She knew she wanted to work with animals by the time she was in eighth grade. Today she is an emergency veterinarian at the Connecticut Veterinary Center. This is a short segment from the "Achieving Goals! Career Stories of Individuals Who Are Deaf and Hard of Hearing: Phenomenal Professionals."
Part of the "A 3-D Demonstration" series. Looks at physics principles behind AC and DC generators. Examines the relationship between a changing magnetic field and the induction of electric current. A hand rule is introduced to predict the generator effect in a linear length of conductor exposed to a changing magnetic field. The behavior of a rotating coil in a magnetic field leads to the practical construction of an AC motor. Introduces split-ring commutator generators, as well as the more common alternator as a means of generating DC electricity. Specific modules include Generating Electricity, Inductors, Generator Left-Hand Rule, Generator Electromotive Rule, AC Generators, and DC Generators. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act).
Earth's landscapes vary because there are different climatic zones that have unique, distinguishing conditions. One of these, the tropic zone, is divided into four more specific zones. The rainy tropics, wet-dry tropics, tropical and subtropical deserts, and tropical highlands are similar, yet different. Includes information on vegetation, animal life, human settlement, urban centers, and climatic conditions.
Rocks, a naturally formed material that covers the earth, are classified by their origin. Discusses rocks' composition, three types (igneous, sedimentary, and metamorphic), how they are formed, and how they are changed. The rock cycle is a slow, ongoing process.
Solutions are classified as acidic or basic based on their hydrogen ion concentration relative to pure water. An acidic solution has a higher concentration of hydrogen ions, and a basic solution has a lower concentration of hydrogen ions. Other topics covered include chemical reaction basics, properties of acids and based, acid-base reactions, and other mixtures. Part of the "Chemistry" series.
Part of the "Chemistry in Action" series. Demonstrates how chemical compounds are placed into groups so that they may be studied easier. Explores acids and bases, emphasizing their nature and common everyday uses. Discusses carbon compounds, and introduces the following terminology: acid, base, pH, salt, carbon, organic, and hydrocarbon.
Host Alex Dainis explains the difference between saturated and unsaturated fats. She also discusses the chemical makeup of fatty acids.
Presents the following songs about animals using American Sign Language: Oh Where, Oh Where Has My Little Dog Gone?; Itsy Bitsy Spider; Bat, Bat; Bear Went Over the Mountain; Croak!!! Said the Toad; Animal Parade; Froggy Went A-Courtin'; Animal Alphabet.
The mid-latitude and polar regions are two of earth's three climatic zones. The mid-latitude, or temperate, regions have definite seasonal changes in temperature and length of days and nights. Polar climates have extremely cold temperatures. Covers the climatic characteristics of the five subregions of the temperate and polar zones, noting also the vegetation, animal and human life, urban centers, and food crops.
Part of the "A 3-D Demonstration" series. Explores the basic principles behind the operation of AC and DC motors. Explains how one or more fixed magnets, either permanent or electromagnetic, can cause linear movement or rotation of a current-carrying wire. A hand rule is developed to predict motor force. Motor torque is explained as a prelude to the practical design of a direct current motor. Specific modules include Motors and Magnets, Current and Magnet Interaction, Left-Hand Rule, Motor Force, Motor Torque, and DC Motors. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act).
Part of the "A 3-D Demonstration" series. Explores how electric energy became an essential tool with the advent of electricity storage, allowing the flow of current to do useful work. Defines and examines conductors, insulators, voltage, and current, using a water flow model to help ensure understanding. Explains the difference between electron flow and current flow models. Also develops the nature of direct and alternating current (both one- and two-phase). Specific modules include Tapping a Source, Conductors and Insulators, Direction of Flow, Potential Difference, Measuring Voltage, Measuring Current, Alternating Current, and AC Voltage. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act).
