SHOW ME SCIENCE ADVANCED - CHEMISTRY & PHYSICS: CHEMISTRY - PERIODIC TABLE OF THE ELEMENTS PART V - UNUNSEPTIUM AND UNUNTRIUM

This program looks at the most recently discovered elements (including Ununseptium and Ununtrium) and the type of commitment and research that is required to make such discoveries. We introduce students to precious elements such as gold, silver and copper and illustrate how "The Big Three" were instrumental in the development of ancient and modern civilizations. Careers in chemistry and element research are highlighted in this dynamic program.

SHOW ME SCIENCE ADVANCED - CHEMISTRY & PHYSICS: CHEMISTRY - PERIODIC TABLE PART IV - IRON, ZINC, SELENIUM

The periodic table organizes elements by an atomic number, based on the amount of protons in each elements nucleus. Other factors include electron configuration and recurring chemical properties. Elements are listed in order of increasing atomic number along with its chemical symbol in each box. The elements iron, zinc and selenium help promote health and fight disease and have commercial uses. Iron zinc and selenium, which happen to exist naturally, are also referred to as trace minerals because humans need only small amounts of them.

SHOW ME SCIENCE ADVANCED - PHYSICAL SCIENCE: BIOLOGY & CHEMISTRY - THE SCIENCE OF FORENSICS

Anthropometry is the science that defines physical measures of a persons size, form, and functional capacities. Forensic science (often shortened to forensics) is the practical application of science to matters of the law. In criminal law, forensics science can help prove the guilt or innocence of the defendant. In civil actions, forensics can help resolve a broad spectrum of legal issues through the identification, analysis and evaluation of physical evidence. This program will discuss how new innovations and discoveries in forensic technology have important scientific applications beyond law.

SHOW ME SCIENCE ADVANCED - TECHNOLOGY: CHEMICAL ENGINEERING COMPOSITES

Composite materials (also called composition materials or shortened to composites) are materials made from two or more constituent materials with significantly different physical or chemical properties, that when combined, produce a material with characteristics different from the individual components. This is an extremely broad definition that holds true for all composites, however, more recently the term "composite" describes reinforced plastics. This program will explain how composites work and what the future holds for these amazing materials.

SHOW ME SCIENCE ADVANCED - TECHNOLOGY: CHEMISTRY METALLURGY

Metallurgy is the study of the extraction, refining, alloying and fabrication of metals and of their structure and properties. Metallurgy can be described as a sub-set of materials science? - the study of physical and chemical behavior of metals and alloys. This program discusses metals role in our control of the environment. Advances in agriculture, warfare, transport, even cookery are impossible without metal, as was the entire Industrial Revolution - from steam to electricity.

SHOW ME SCIENCE ADVANCED - CHEMISTRY: PERIODIC TABLE OF ELEMENTS - POTASSIUM (K) AND MAGNESIUM (MG)

The Periodic Table is organized with elements specified in rows, or periods, according to increasing atomic number. Metals are on the left of the periodic table, while nonmetals are located on the right. Some in the middle are called metalloids because they have characteristics of both metals and nonmetals. The periodic table is purposely arranged into vertical classifications called groups. Columns of elements help define element groups. Some of the notable groups of elements include the noble gases (column 18), the halogens (column 17), the alkali metals (column 1) and the alkaline earth metals (column 2). The transition metals are located in the center of the periodic table. They include many of the common metals, such as copper, iron, silver and gold. The two rows below the main body of the table are called the lanthanide and actinide series. They include the very heavy metallic elements, such as uranium and plutonium. This program goes in depth regarding the elements potassium (K) and magnesium (Mg) and their roles in the health of the human body. Potassium helps to control the proper balance of fluids in cells, helps with the contraction of muscles, and is involved in the transmission of chemical messages between nerve cells. Potassium aids in digestion of food, and in the proper function of the eyes. Magnesium is needed for more than 300 biochemical reactions in the body. It helps maintain normal muscle and nerve function, keeps heart rhythm steady, supports a healthy immune system, and keeps bones strong.

SHOW ME SCIENCE ADVANCED - NATURES CHEMICAL WONDER: ACID CAVES EXPLORED

Deep in Southern Mexicos jungle, the Villa Luz limestone caves support an ecosystem that thrives in a highly poisonous, acidic environment. This rare type of cave is found in few spots on Earth. The Villa Luz, is known for the bacteria in its thermal sulphur springs that produce hydrogen sulfide gas. When the gases form bonds with oxygen, the result is sulfuric acid. The acid eats away at the cave walls, constantly altering the patterns in the cretaceous limestone. All life forms, from microbial colonies to spiders, fish and bats, are interdependent upon the toxic soup of water, sulphur-oxide and hydrogen monoxide for survival. Surprisingly, the caves are home to spiders, bats, and a unique fish species referred to as the Cave Molly. The caves are also well known for their snottites, which are mucous-like formations that resemble stalactites. Descending into the caves is very dangerous as there are potentially lethal levels of hydrogen sulfide gas. Researchers carefully plan expeditions into the caves to better understand these rare ecosystems and must wear respirators and protective clothing as they enter the cave system in their attempt to document and understand the deadly ecosystem.
