All living organisms on Earth contain cells which are the basic structural unit for all organisms. Cells are small compartments that hold the biological equipment necessary to keep an organism alive. They also have specific parts to make the cell work.

The human brain is wired to perceive patterns and structure in surrounding environments. Young children especially need structure to feel secure. Yet the developing brain is also continuously seeking new information. Discover how to give young children the structure they need to establish a strong foundation for continual learning. Part of "The Brain" series.
Molecules form when individual atoms create bonds by sharing electrons. Understanding how atoms combine to make molecules allows scientists to predict many of the physical and chemical properties of substances. Since the outermost eight electrons are key to forming compounds, this unit shows how the Octet Rule provides a basis for predicting how atoms may gain, lose, or share electrons to fill the slots in their outer shells. A fundamental understanding of how electrons form bonds leads to the three-dimensional shapes of molecules and has implications in all aspects of chemistry. Part of the series Chemistry: Challenges And Solutions.
This video outlines the complementary nature between structure and function. Students will observe specific animals that have structures geared towards a particular function. Topics covered include the structures and processes animals use involved in breathing, eating, passing waste, and moving. Part of the "Biology" series.
The hummingbird has a forked tongue that is lined with hair-like extensions. Its design is especially useful for drinking nectar from flowers.
Using light as a probe, scientists found innovative ways to make inferences about the inner structure of the atom. In this unit, scientists discuss the change from believing the atom was a single indivisible particle to later understanding the atom is composed of subatomic parts. This new picture of matter lead to the development of the quantum model of the atom, as well as ways to identify traces of chemical elements, whether on earth, in the sun, or in a distant galaxy. Part of the series Chemistry: Challenges And Solutions.
While it is relatively straightforward to build a box on the macroscale, it is much more challenging at smaller micro and nanometer length scales. At those sizes, 3D structures are too small to be assembled by any machine and they must be guided to assemble on their own. With support from the National Science Foundation, Brown University mathematician Govind Menon and Johns Hopkins University chemical and biomolecular engineer David Gracias are developing self-assembling 3-D micro and nanostructures which can be used in a number of applications, including medicine.
Proteins are the workhorses of cells. With support from the National Science Foundation, University of Arkansas biochemist James Hinton has been researching their structure and function for decades. Back in the 1990’s, he had a vision to study these huge protein structures in 3D and now, in cooperation with a company called Virtalis, his vision has become a reality. The new system allows researchers to enlarge the visual of a protein to room-size, so they can examine it from all angles, to better understand its structure and function. The new 3D visuals are also helping Hinton realize his other vision to better engage students in his discoveries and science in general.
Why is RNA just as cool as DNA? Join the Amoeba Sisters as they compare and contrast RNA with DNA. Part of "The Amoeba Sisters" series.
Part of the "Inside the Living Cell" series. Provides an overview of the different kinds of cells, emphasizing the fact that all cells have a common organizational structure and carry out similar biochemical processes. Presents the discovery of cells, cell structures, organelle function, cell varieties, and the chemistry of life.
The researchers are building scaffolds that mimic the three dimensional structure of human tissue. They use a machine called a biofabricator to deposit cancer cells at strategic locations inside the 3D structures, just like tumors in human flesh. These structures are high fidelity test systems. Burg and her team can culture cancer cells in them, experimenting to see which treatments are the most effective, with the ultimate goal of personalizing a treatment or a vaccine for individual patients. Part of the National Science Foundation Series “Science Nation.”
Outlines the characteristics, shapes, and structures of viruses and monerans, more commonly called bacteria. Notes ways that both affect our lives.
Follow a structural engineer through a busy day of working with sophisticated design tools. He is tasked with creating safe, long-lasting structures. Part of the "Career Connections" series.
In this episode, scientist Steve Lord explains the relationship between gravity and the shape of galaxies. Gravitational forces from the galaxy's core causes all the stars to rotate. This rotation causes spiral waves. Part of the "Ask an Astronomer" series.
Diagram of the internal view of the female reproductive system. Design modalities for the image include braille with and without labels, print with and without labels in greyscale, color, and texture.

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.
Part of a series that features a wide variety of video footage, photographs, diagrams, graphics, and labels. For this particular video, students will focus on single gene disorders which cause genetic diseases like cystic fibrosis, fragile X syndrome, and muscular dystrophy. Part of the Science Video Vocab series.
In many ways our brains may be like those of animals, but in our capacity to think, to remember, and to create we are much different. Looks at some of the reasons for these differences, exploring the neural structure of the human brain, our physiological brain capacity, and the use of memory and symbols.
Geophysicist Emilie Hooft describes her work and the important role physics plays in understanding volcanoes. She also reveals how data helps create the images of magma structures beneath volcanoes. Part of the “EarthScope Chronicles” series.
Part of the "Chemistry in Action" series. Describes and illustrates the process of chemical bonding through live action footage and animations. Provides an overview of the role atomic structure plays in the process of bonding. Provides examples of how chemical bonding, including ionic bonds, covalent bonds, and metallic bonds, affects the characteristics of matter. Introduces the following terminology: element, atomic structure, energy level, valence electrons, ionic bonds, crystal lattice, covalent bond, and metallic bond.
