The most common bacterial shapes are rods, cocci (round), spirals and filaments. Groups of these cells can be differently arranged in space. Four 3D-printable models illustrate these shapes and arrangements.

Host Trace Dominguez discusses the current trends in the number of hurricanes and their strength. He examines weather data collected since 1880 coupled with new models created by NASA. According to the data and weather models, hurricanes are becoming more intense.

Colony formation on semi-solid medium is basic characteristic of many different bacteria and an important property for microbiologists. These models illustrate the different types of colonies formed, what a colony reflects at the cellular level, how microbiologists obtain isolated colonies, and what happens when cells swarm instead of forming colonies.
Most bacteria grown by fission, one cell dividing into two. When nutrients are abundant, this can result in exponential growth, with a large increase in the number of cells over a surprisingly short period of time. Bacterial cell division and the characteristics of exponential growth are illustrated with four, 3D printable models
How can cake ingredients be whipped into a moon-like crater? A scientist from NASA demonstrates how to construct craters out of household items. Part of the “DIY Space Classroom Activities” series.
Presents the principles of weather dynamics. Shows how weather conditions are measured, how computer models are used to predict the weather, the special role of moisture in producing weather phenomena, and finally, the impact of hazardous weather.
Discover how the James Webb Space Telescope will help scientists studying the formation of stars. The telescope will provide infrared observations and give astronomers an unprecedented view of stellar birth. Computer models show how a giant cloud of gas and dust collapses to form stars and planets.
Vertebrates use their backbones to move in a variety of ways. Observes and comments on the movement of fish, moray eels, newts, salmon, cheetahs, dolphins, birds, and babies. Highlights the differences and similarities of their movement. Motorized models reveal precisely how some animals' backbones move.
Part of the "Active Physics, Third Edition" series. Contains the following sections: "Using Models: Intersections with a Yellow Light," "Sports Montage Introduction," "Conservation of Energy: Defy Gravity," "Safety Montage Introduction," "Acceleration Due to Gravity: Free Fall on the Moon," and "Modeling Human Motion: Bounding on the Moon."
A new software, Columbia 3.0, has been created thanks to the growth of mobile applications, technological improvements in the world of computers, and the creation of new business models. This event was sponsored by the Ministry of Information and Communication Technologies and aims to improve the quality of audiovisual and virtual content in both professional and academic arenas.
This demonstration uses a water balloon to show how Earth's oceans are absorbing most of the heat in the atmosphere. The trapped heat in the ocean is warming the planet. Part of the “DIY Space Classroom Activities” series.
A Scientist from NASA explains how to easily build an inexpensive planetarium to introduce students to star patterns. The activity also allows students to create their own constellations. Part of the “DIY Space Classroom Activities” 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.
The habitats of several jungle animals are severely threatened. Organizations are working with local inhabitants to develop conservation models that ensure the jaguar, the scarlet macaw, the Howler monkey, and other species will continue to have a place to call home. Part of the "Bios: Nature and Society" series.
Volcanic ash is geographically the most widespread of all volcanic hazards. The United States Geological Survey (USGS) geologist Larry Mastin describes how volcanic ash can disrupt lives many thousands of miles from an erupting volcano. The development of ash cloud models and ash cloud disruption to air traffic is highlighted.
University of Colorado engineer Abby Watrous is on a mission in rural China, converting coal-burning homes and cook stoves into cleaner-burning models. With funding from the National Science Foundation, this civil and environmental engineer is helping to develop renewable energy technologies in developing communities. Watrous and her colleagues are looking at ways to help more people use biomass.
Structural engineers at the University of California, Los Angeles are hoping to design earthquake-resistance buildings and communities. They are using data and computer modeling to design structures able to withstand major earthquake events. These models are meant to guide safety inspections following earthquakes and help engineers locate “hotspots” more quickly. Part of the “Science Nation” series.
There was a time when few knew what dinosaurs looked like. This is the story of how Waterhouse Hawkins built the first life-sized dinosaur models and stunned the world with his creations. Based on the book by Barbara Kerley.
Thrill seeking, extreme sports, and even dangerous professions all push the human body to its limits. The question is: How much can the human body handle? Newer technology enables doctors to simulate stressful events on models and monitors. Then, with the help of science, new products can be created to assist the human body in these situations.
Second in the series of three productions designed to let students learn by doing, guiding them through the science and history behind the Wright Brothers' invention of powered flight. This second component contains segments that provide science background (Four Forces of Flight, Newton's Laws, and others) to help students understand aviation concepts. Additional segments show the teacher how to conduct activities (building models or demonstrations) and acquire materials to be used in these activities.
