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

Dot, the fire dog, and her firefighter friends know exactly what to do when the alarm bell rings at the fire station. Based on the book by Lisa Desimini.
What is biodiversity? Students explore the concept of biodiversity as it applies to a wide range of ecosystems on Earth.
Part of a series that features a wide variety of video footage, photographs, diagrams, graphics, and labels. Also concludes with a critical thinking question. For this particular video, students will focus on the diverse group of eukaryotic organisms known as protists. Part of the Science Video Vocab series.
In each episode, viewers are given clues about a hidden animal inside a magic box. Can viewers use all the clues to correctly guess the name of this stinging arachnid that carries its tail curved over its back? Part of the "Zoobabu" series.
In each episode, viewers are given clues about a hidden animal inside a magic box. Can viewers use all the clues to correctly guess that the mystery animal in this episode is a duck? Part of the "Zoobabu" series.
In each episode, viewers are given clues about a hidden animal inside a magic box. Can viewers use all the clues to correctly identify this mud-loving farm animal? Part of the "Zoobabu" series.
In each episode, viewers are given clues about a hidden animal inside a magic box. Can viewers use all the clues to correctly identify this free-swimming marine animal with umbrella-shaped bells and trailing tentacles? Part of the "Zoobabu" series.
Hidden in a vault outside Paris, vacuum-sealed under three bell jars, sits a palm-sized metal cylinder known as “Le Grand K.” Forged in 1879 from an alloy of platinum and iridium, it was hailed as the perfect kilogram—the gold standard by which other kilograms would be judged. However, it is wasting away, and scientists are scrambling for a more reliable standard. Part of the "Uno Dos of Trace" series.
Snakes certainly make it look easy when they slither forward, leaving perfect S-curve tracks behind them, but scientists have long been puzzled by the mechanics of their locomotion. Now, after a series of experiments and some computer modeling, David Hu has cracked the case. With funding from the National Science Foundation, he’s using math to determine how snakes slither and it turns out they move in a much different way than scientists have long thought.
Students receive an overview of nutrition basics starting with an in-depth look at nutrients. This program also provides an overview of nutrition standards and guidelines. Part of the "Human Nutrition" series.
Features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition, and this helps clarify pronunciation and provides opportunities to transfer words from working to long-term memory. Also concludes with a critical thinking question. For this particular clip, students will focus on fish.
When is it necessary to induce or augment a labor? Answers questions expectant parents may have about these procedures. Explores the advantages, risks, common medical methods, and natural alternatives available for both induction and augmentation. An obstetrician lists questions expectant parents should ask their caregivers. NOTE: Concludes with footage of a vaginal birth.
To change a spacecraft's speed and direction, NASA engineers use a planet's or moon's gravity, a process called a "gravity assist." In this video, students design and build systems that use magnets to control the speed and direction of a rolling ball. As they build their systems, they use the engineering design process, apply a variety of science concepts, and learn how NASA spacecraft use gravity to help them explore the solar system. Part of the "Design Squad Nation" series.
Mosquitoes are annoying pests. They can interrupt a backyard picnic, and their bites cause red, itchy bumps. These pests can also carry viruses that make humans sick. In this episode, learn how and why the invasive Asian tiger mosquito is even more problematic than other varieties. Part of the "Seasonal Science" series.
Juncos, also known as snowbirds, are readily observed in backyards, city parks, and forests. These little gray birds are so common they can be easily overlooked. But for scientists who study animal behavior, ecology, and evolutionary biology, the junco is a rock star. Part of Ordinary Extraordinary Junco (Intro).
Find out how Albert Einstein used the totality phase of the 1919 solar eclipse to prove his theory of relativity, which predicts that large objects bend “space-time” towards themselves.
Why do some birds, like raptors, move from one region to another at certain times of the year? It is all about their interactions with the environment. The primary factor is scarcity in a food source. Another factor includes changes in the weather. This episode explains the seasonal events that affect the raptor’s migration and provides a platform to investigate the types of relationships found in their ecosystem. Part of the "Seasonal Science" series.
