Features different systems of measurement and their value to science in five separate segments. Stardust Elements: Looks at the life cycles of stars and explains how the death of a star seeds the universe with all the elements of the periodic table. End of Dinosaurs: Debates several scientific theories about why and how dinosaurs became extinct. Earthly Thermometers: Demonstrates how the Fahrenheit, Celsius, and Kelvin scales measure the same thing in different ways and why we need precise measurements of temperature. Frozen in Time: Pieces together the past of a 5,300-year-old man whose body was preserved in ice in the Italian Alps. Hurricanes Take the Heat: Follows researchers who study how hurricanes form and try to predict where the next one will strike.
A key to building denser, stronger materials that won’t fail or fracture under extreme conditions is the manufacture of ultra-high temperature, or UHT, ceramics. UHT ceramics can withstand highly extreme conditions, such as the heat coming out of a rocket as its launching into space. Part of the National Science Foundation Series “Science Nation.”
Host Trace Dominguez discusses the science behind getting a fever when sick. Fevers are integral to effective immune responses and ensure the immune system takes appropriate action against the offending virus or bacteria. Part of the "Uno Dos of Trace" series.
Weather is the state of the atmosphere, and it refers to the day-to-day temperature and precipitation activity. The difference between air pressure, temperature, and moisture influence weather-related phenomena. Other topics covered include evaporation, relative humidity, clouds, precipitation, rain gauge, air mass, front, thunderstorm, hurricane, tornado, weather forecast, meteorologist, and satellite imagery.
Live-action weather footage helps students learn how they can observe the weather. Concepts and terminology discussed include: temperature, air pressure, weather systems, precipitation, and wind.
Students will explore how molecular movement is related to temperature, and how temperature can be measured. Important terminology includes thermometer, thermal energy, kinetic energy, potential energy, energy conversion, molecules, and heat.
Presents three key biological concepts about homeostasis: controlling body temperature, controlling water level, and controlling blood sugar. Each concept is illustrated with a variety of experiments and computer animation to illuminate what is happening both visibly and at the molecular level.
The state of matter is the form taken by matter at a given temperature and pressure. A phase of matter is uniform with respect to its physical and chemical properties. Matter undergoes phase transitions to change from one phase to another. Part of the "Chemistry" series.
Experiments show the production and properties of carbon dioxide and its use as a fire extinguisher. The second part demonstrates the effect of surface area, temperature, and concentration on chemical reaction rates.
In this chapter, other scientists from Kazakhstan will challenge the House of Science Scientists. During the challenge, the scientist answer the question does the temperature at which water or other fluids boil change according to the altitude of the geographical place? Part of the House of Science Series.
Can superhero Bruce Rain help reduce the effects of global warming? First he has to understand the relationship between greenhouse gases and the temperature of the Earth. Dr. Mother Nature also explains how the rising temperature of the Earth impacts various environmental and ecological systems. Part of "The Science of Climate" series.
The temperature of the Earth is dropping, and superhero Autumn Ray must find a safe way to heat the planet. At first she thought the answer was to increase the amount of greenhouse gases, but Dr. Mother Nature tells her there has to be a safe balance of gases to regulate the temperature of the Earth. Part of "The Science of Climate" series.
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.
Uses the extremes of temperature that occur in a day's skiing to show the range of mechanisms through which the human body maintains a steady internal temperature and protects its vital organs, such as shivering, hair erection, and rerouting of blood supplies to conserve heat. Increased blood flow to the body surface, sweating, and panting to lose heat is also reviewed. NOTE: Contains some nudity.
The Standard Deviants start off with the concept of heat transfer. Students learn how much energy it takes to raise the temperature of a substance. This episode also discusses how matter changes state. Part of the "Standard Deviants School: Physics" series.
Gallium is a chemical element with the symbol Ga and atomic number 31. Elemental gallium is a soft, silvery metal at standard temperature and pressure; however in its liquid state it becomes silvery white.

Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas.
Caesium has the atomic number 55 and symbols Cs. It is an alkali metal with a silvery-gold color and the only liquid metal from the group of elemental metals, which is liquid near or at room temperature.
Mercury is a chemical element with the symbol Hg and atomic number 80. It is commonly known as quicksilver and was formerly named hydrargyrum. It is the only metallic element that is liquid at standard conditions for temperature and pressure.
Provides an overview of Antarctica's icy habitat. Describes how the seasons affect temperature and daylight. Shows how animals in the water are adapted for the cold. Focuses on the emperor penguin and how it raises its young.
