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.
(Source: DCMP)
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.
Gives a general introduction to microscopes, a device invented 400 years ago. Begins with a simple magnifying glass and moves to the optical, confocal, electron, scanning electron, and the scanning tunneling microscopes. Shows that each one "sees" with increasing detail. The microscope opens invisible worlds and aids scientists in improving ours.
Demonstrates techniques for using a student microscope to achieve spectacular images. Emphasizes correct lighting procedures and the techniques required for viewing living cells.
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 the correct steps of preparing a microscope slide when conducting experiments in a lab. Part of the Science Video Vocab 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.
This video explores the fascinating world of microscopic life. It begins by discussing viruses and explaining how they cause disease. Students also learn the importance of bacterial cells and explore the life of protists. Additional concepts and terminology include microscope, vaccine, moneran, decomposition, amoeba, phytoplankton, yeast, algae, paramecium, and protozoa.
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.
Uses practical examples to help students understand and use the components of the scientific method. Concepts and terminology: hypothesis, experiment, measuring, data, analysis, and conclusion.
Roselle Rojas shows some of the latest biochemistry projects taking place at Gatorade's Sport Science Institute and what her typical day is like inside and outside the lab.
Dr. Ronald Evans describes how fat communicates with muscle and how diet and exercise influence that relationship. Part of the 2004 Howard Hughes Holiday Lecture Series.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition of the term and concludes with a critical thinking question. For this particular video, students will focus on the term biochemistry. Part of the Science Video Vocab Series.
Rotifers are found in still waters, and there are over 2,000 species. They all have two crowns of cilia that work in sync to help them move and gather food. One of nine segments in a series, with all nine available on a DVD.
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.
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 a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition of the term and concludes with a critical thinking question. For this particular video, students will focus on the term chemistry. Part of the Science Video Vocab Series.
Worldwide, more than 40 million people have Alzheimer’s. Each being stripped of their memories and often their dignity. More than 100 years ago, a doctor identified two possible causes of Alzheimer’s: gooey plaques and fibrous tangles in brain tissue. This documentary investigates both and highlights the key researchers in the field who have helped to develop the leading theories of the disease.
Amy Battocletti is a Navy veteran who was awarded an NSF Graduate Research Fellowship in 2014. She’s a doctoral candidate in biology at Georgetown University, conducting research on the impact of genetic variation within plant species in salt marsh ecosystems. Part of the Scientists and Engineers On Sofas Series.
Updates the five kingdoms classification scheme with the latest understanding of life's organization based on DNA, fossil, and biochemical evidence, reorganizing all life into three great branches: Archaea, Bacteria, and Eucarya. Shows concise animations and superb microscope footage of primitive cells.
Ever since Willie Bentley was a young boy, he was fascinated with snowflakes. He looked at them under a microscope and studied their icy crystals. He even drew pictures of them, finding no two snowflakes exactly alike. Based on the true story of Wilson Bentley and the children's book by Jacqueline Briggs Martin.
