Through observation and experimentation, students will learn properties of forces, Newton’s Laws of Motion, and how pressure affects the world. Real world examples encourage students to explore their surroundings and to discover the impact forces have on everyday life. Part of the Real World Science series.

A hurricane hunter is a pilot that flies an airplane into the middle of a hurricane. They gather data on temperature, humidity, and air pressure. This data is critical for forecasting the intensity and path of hurricanes. Part of the "NOAA Ocean Today" series.
Presents sensory receptors that depend on contact with the immediate world: taste buds, touch sensors, and olfactory cells. These receptors lie in the skin, the largest organ of the body, which also senses heat, pain, and pressure. Re-creates the complex world of the skin through realistic models and photographs.
This video explores the daily condition of the Earth's atmosphere, and the factors that influence and cause weather. Special emphasis is given to the global processes that generate weather patterns. Other topics covered include conduction, convection, radiation, thermometer, barometer, air pressure, winds, anemometer, sea breeze, land breeze, doldrums, trade winds, prevailing westerlies, polar easterlies, and jet streams.
Some conservationists believe that perhaps half of all species on earth will become extinct in the next 50 to 100 years. To prevent that, several groups work to assist efforts at conserving biodiversity. Some of the efforts include taxonomy (cataloging species), managed retreat (letting nature retake areas), saving seeds, and propagating endangered plants. Man's efforts toward destruction and development must be balanced with sustainability.
Discusses the importance of monitoring the cardiovascular system and explains the process of respiration in the body. Animations demonstrate how the organs in the heart work to pump blood throughout the body. Other terminology includes: blood vessel, artery, pulse, vein, aorta, septum, atrium, ventricle, capillaries, pulmonary circulation, systemic circulation, coronary circulation, blood pressure, sphygmomanometer, plasma, red blood cells, white blood cells, platelet, lungs, and alveoli.
A solution is a homogeneous mixture of two or more substances. It contains a solute and and solvent. Solubility is the maximum quantity of a solute that can be dissolved in a given amount of solvent at a specified temperature. Other topics covered include concentration, Raoult's law, colligative properties, and non-ideal behavior. Part of the "Chemistry" series.
The parakeet starts with a monologue about the pleasure of eating. The first guest, the pork, says he can't sleep because the sloth wakes him up every night with phone calls at indecent hours. The sloth says that since he changed his diet he has so much energy that he can't sleep. The fleas present a documentary about the way humans eats. The celebrity guest, a burger commercial clown, tells us how the pressure of fame took him to an eating disorder.
Geothermal energy is one of the oldest renewable resources used by humans. It has been used since the ancient Roman times as a heat source. Recently, it has been harnessed and used as a source of power. Explains a few different ways that geothermal power plants operate. Discusses how experts are working to fine-tune the process and make the power plants more affordable and useful across the country.
Homeostasis refers to the body’s ability to maintain a stable internal environment, and maintaining homeostasis requires that the body continuously monitors its internal conditions. From body temperature to blood pressure to levels of certain nutrients, each physiological condition has a particular set point. Topics covered include homeostasis, negative feedback loop, nervous system, endocrine system, digestive system, excretory system, musculoskeletal system, and the immune system. Part of the "Biology" series.
In a gas turbine, the linear motion of gas causes rotors to spin, ultimately creating electricity. The forward rotating blades pump air under high pressure into the combustion chamber where natural gas ignites on contact with the air. At 1,500 degrees Celsius, the stream of gas rushes past the rear turbine blades, causing the entire rotor to spin. A generator transforms that rotational energy into electricity.
As shown on the History Channel. Over 20 years ago, Mount St. Helen's--thought to be dormant--shocked America when it exploded. It is an acidic volcano--the magma beneath is full of volatiles making it highly explosive. A new plug has formed in its throat and is rising. When it blows, it will be like uncorking a champagne bottle, releasing pressure below and allowing dissolved gases to escape and explode. The question is, When will it blow again?
As shown on the History Channel. From Alaska to New Mexico, the Rockies are one of the great mountain belts of the world--caused by tectonic forces of the Pacific Plate pushing against the North American continent. They have formed as the earth's continental crust has been shortened under pressure, by around one inch a year. What's more, they are still rising and they are still young in geologic terms: when the dinosaurs roamed the Earth they had not even started to form.
Students receive a crash course in the physiology and functioning of their hearts as well as how to keep their hearts healthy. Animations clarify how the heart works to provide oxygen and nutrients to all the tissues and organs of the body. They also detail what can go wrong. The program stresses that even teenagers can show early signs of atherosclerosis and other heart problems. Two cardiologists and a dietitian then pinpoint the main risk factors for an unhealthy heart, including: smoking, abnormal levels of cholesterol, high blood pressure, obesity, diabetes, and physical inactivity.
Born in 1962 and captured as a baby, Ivan was brought to a mall in Tacoma, Washington. For 27 years shoppers flocked to the mall to see Ivan, but public pressure built until a better way of life for Ivan was found at Zoo Atlanta. From the Congo to America, and from a local business attraction to a national symbol of animal welfare, Ivan the Shopping Mall Gorilla traveled an astonishing distance in miles and in impact. This is a true story based on the book by Katherine Applegate.
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.
The Darién Gap is a remote tropical forest that has been home to indigenous people for thousands of years. As pressures from outside human development encroach on the forest, these communities are protecting their land using a cutting-edge tool: drones. Through a partnership with a nonprofit organization, the Rainforest Foundation, they map their community boundaries to secure land titles, create sustainable land-use plans, and monitor their forests against logging and ranching.
Home to 25% of all marine species, coral reefs protect the coastlines of more than 100 countries and provide 500 million people with jobs. However, reefs are experiencing damage due to climate change, ocean acidification, and other pressures. Mote Tropical Research Lab and the Coral Restoration Foundation, both in the Florida Keys, are performing groundbreaking work by accelerating coral growth in the lab, creating nurseries in the ocean, and replanting on damaged reefs. Their efforts create hope for the future of sustainable coral reefs around the globe.
This video describes how indigenous communities from the tropical rainforest of Darién, Panama, use drones to map their lands. The communities use these maps to protect their territories from outside incursions and to design sustainable land-use plans.
