Semiconductors are in everything from cell phones to rockets. But what exactly are they, and what makes them so special? Find out from an electrical engineer. Part of the "Science Out Loud" series.
Students will trace the history of chemistry and study accounts of how chemistry developed from a practical discipline into a science. This episode also presents a current, real-life application of chemistry by illustrating the process of the refining and purifying pure silicon for advanced electronics, such as cell phones and solar cells. Part of the Chemistry: Challenges and Solutions Series.
Modern emails, pagers, faxes, and cell phones! It's all about communication with Timeblazers Sam and Jen, who travel back to test out different communication methods. The message-in-a-bottle tactic proves it could be a long wait before the tide comes in to carry the bottle to sea. It wasn't that long ago that to "log on" meant to throw a log on the fire to send smoke signals. There was the Pony Express and horse-drawn stagecoaches in the 1800s. Then came carrier pigeons, the telegraph, telephones, the Post Office, and overnight delivery.
Iridium is a rare element used to light up cell phones and TVs. However, researchers have found a way to use a more common element to power electrical devices: copper. Researchers are also developing a better treatment for osteoarthritis through nanotechnology. Other segments include research into specialized metabolites and devices that translate sign language. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.
Basic educational diagram showing a cross section of an animal cell. Design modalities for the image include braille with and without labels, print with and without labels in greyscale, color, and texture.

Students explore the smallest, but most important units of life: cells. They also gain an understanding of common cell parts through lifelike animations. Additional concepts and terminology include building blocks of life, animal cell, cell membrane, nucleus, cytoplasm, plant cell, photosynthesis, cell wall, chloroplasts, organelles, and role of cells in the body.
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

Provides an overview of the cell--the building block of life. Covers different kinds of microscopes, the discovery of cells, and the cell theory before focusing on a cell's characteristics and organization. Includes a quiz.
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.
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.
Illistration of the Procaryotic Cell
(Source: OpenStax)
Delves into the inside of a cell. Provides the proper labeling of the important parts of the cell and the function each part performs. Discusses how cells are the basic building blocks for life and how cells can create and store energy.
Discusses how the activities and processes of cells affect our lives. Covers metabolism, diffusion, respiration, and cell growth and mitosis. Includes questions and a quiz.
Deeply explores the structure of both plant and animal cells. Demonstrates the different types of cells, their components, and their functions
The cell cycle, or cell-division cycle, is the series of events that take place in a cell that cause it to divide into two daughter cells. In this episode, Pinky and Petunia discuss the steps of the cell cycle and what happens when the cell cycle doesn't work correctly. Part of "The Amoeba Sisters" series.
All living things are made from one or more cells. A cell is the simplest unit of life, and they are responsible for keeping an organism alive and functioning. In this episode, Pinky and Petunia discuss the organelles of cells. Part of "The Amoeba Sisters" series.
Part of the "Visualizing Cell Processes" series. Includes the following modules: "The Cell Machinery," "A Variety of Cells," "Organic Molecules: The Building Blocks of Life," "Prokaryote Evolution and Diversity," and "Independently Living Eukaryotic Cells."
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.
Part of the "Inside the Living Cell" series. Shows how DNA replicates; how copy errors occur and are subsequently corrected by repair enzymes; and how DNA is compressed into chromosomes, making mitosis and cell division possible. Provides an overview of DNA structure, replicating DNA, mutations that change the genetic code, proofreading and repair, and the stages of mitosis.
