It's called a theory, but if we have never seen an atom, how did anyone ever come up with an idea that is so central to science. Shows how all the pieces of the puzzle have come together at the same time, explaining the structure of the atom and the periodic table.

Sherlock Olmos decides to dig deeper into dark corner of this great house to investigate the suspicious behavior of some chemical elements. The exchange of electrons and the characteristics of hydrogen, fluorine gas, and the noble gases are the primary subjects of his investigation. Part of Chemistry: Solved by Sherlock Olmos Series.
Carbon (from Latin: carbo "coal") is a chemical element with symbol C and atomic number 6. On the periodic table, it is the first (row 2) of six elements in column (group 14), which have in common the composition of their outer electron shell. It is nonmetallic and tetravalent - making four electrons available to form covalent chemical bonds. Three isotopes occur naturally, 12C and 13C being stable while 14C is radioactive, decaying with a half-life of about 5,730 years. Carbon is one of the few elements known since antiquity.

In this episode, host Dianna Cowern explores how magnetic paper works. She uses the paper on common electronic devices to reveal all their magnetic parts. Part of the "Physics Girl" series.
At the National Science Foundation-funded Center for Environmental Implications of Nanotechnology (CEINT), headquartered at Duke University, scientists and engineers are researching how nanoscale materials affect living things. One of CEINT's main goals is to develop tools that can help assess possible risks to human health and the environment. A key aspect of this research happens in mesocosms, which are outdoor experiments that simulate the natural environment. These simulated wetlands in Duke Forest serve as a test bed for exploring how nanomaterials move through an ecosystem and impact living things. Part of the “Science Nation” series.
What if the source codes for the Internet had remained with the U.S. military rather than being released to the world? How did civilians gain unfettered access to the Internet? Three key events contributed to the development of this modern technology: the launch of Sputnik, the United States military conducts an ambitious project, and computer scientist Tim Berners-Lee invents the web and puts the very first Internet site on line. Part of the "Butterfly Effect" series.

Introduces cells, how they function, the differences between plant and animal cells, and the various parts of the cell. A quiz is given after each topic.
Pinky and Petunia discuss light and electron microscopes. They also offer helpful hints on how to use a light microscope. Part of "The Amoeba Sisters" series.
Part of the "Branches on the Tree of Life" series. Uses crisp graphic animation to describe the molecular-level mechanisms of photosynthesis. Examples of this critical element of plant biology include the major plant groups of mosses, liverworts, ferns, horsetails, and the seed plants (gymnosperms and flowering plants).
Diagram of a helium atom. Design modalities for the image include braille with and without labels, print with and without labels in greyscale, color, and texture.
Diagram of a lithium atom. Design modalities for the image include braille with and without labels, print with and without labels in greyscale, color, and texture.
Provides an overview of magnifiers and microscopes. Identifies a microscope's parts, use and care, and shows how to handle slides. Covers the development and changes of the microscope and its contribution to scientific discovery. Compares the standard light and the electron microscopes. Uses multiple examples of magnification to show why this tool is important to research.
Grab a balloon to explore concepts of static electricity such as charge transfer, attraction, repulsion, and induced charge.

Biology is the study of life. It encompasses the cellular basis of living things, the energy that underlies the activities of life, and the genetic basis for inheritance in organisms. Topics covered include the smallest components of living things: atoms, molecules, organelles, and cells. Part of the "Biology" series.
Adabot learns all about diodes and their role in an electrical circuit. Diodes act as a safety feature and ensure the electrical current flows in the correct direction. Part of the "Circuit Playground" series.
Information and Communication Technologies, known as ICT's make reference to electronic devices used for specific communication purposes, for example: television, radio, Internet, cell phone, iPhone, iPod, computer and other technological innovations that are part of the information culture.
Cell regeneration, cloning, prosthesis, electronic devices in the human body, bionic eyes and hands, are current technologies developed in favor of improving rehabilitation and quality of life. Nerdo Cavernas reveals the technology being used to enhance and improve rehabilitation.
Students learn the fundamental concepts of electrical energy. Easy-to-understand animations illustrate the concepts of electric charge and electric current. Static electricity and the role it plays in creating lightning is also described. Important terminology includes protons, electrons, repel, attract, charges, charged objects, electrical discharge, electric field, and electric force.
