3-D animation shows the uptake of oxygen by the red blood cells at the alveoli. Shows how hemoglobin binds to the oxygen to transport it through the circulatory system to the tissues. Grades 7-12. 3:09 min.
DNA Molecular Structure
This 3D scientific animation dynamically show a zoom in from a group of dividing cells to a close-up of a DNA molecule. No voice. Grades 5-12. 39 sec.
How a Virus Works
This narrated animation explains what a virus is and how it functions. It relates the way a virus works to nanotechnology. The human immune system fights an infection, like a virus, using various types of cells. The body has to adapt to infections and the dead cells are carried to the lymph nodes.
In this video adapted from NOVA scienceNOW, learn how the common wood frog survives the cold winter. Wood frogs are found in the northern United States and Canada and must endure freezing cold temperatures for parts of the year. In order to survive the cold, they have a special adaptation—they are able to freeze solid without damaging their cells. Sugar acts like a natural antifreeze in their bodies, allowing them to spend the winter frozen and then resume function in the spring. Run time 03:3
Dyslexia : Types of Dyslexia
Video is presented by Dr. Diane Sawyer. There are four main types of dyslexia; the first one is the most common it is phonological dyslexia, This is where children have difficulty separating out the parts of language, such as words within sentences and sounds within words. Then orthographic dyslexia, means the individual has difficulty with the spelling patterns. The last type discussed is dyscalculia, which is having the difficulty with mat
Three Types of ADHD
Three Types of ADHD. Part of the series: How to Tell if Your Child Has ADHD. Learn about Three Types of ADHD in this children's health video.
Hydrogen From the Sun
This video looks at hydrogen production using electrolysis as one option for storing energy from the sun. The video includes a brief explanation of fuel cells.
The Electromagnetic Spectrum
The electromagnetic spectrum allows physicists to classify different types of electromagnetic waves on the basis of their wavelengths and frequencies. What determines the wavelength and frequency of a given wave and distinguishes one wave on the spectrum from another is the amount of energy each wave carries -- specifically, the level of energy in the photons of each. This video segment adapted from FRONTLINE explores the different types of radiation represented by electromagnetic waves and how
Symbiosis Rap Song
Check out this rap song about symbiosis (when different types of organisms interact for long periods of time). The song will discuss the symbiotic relationship between pine trees, pine bark beetles, and bluestain fungi. The repeated verse is catchy and can quickly teach children about mutualism and parasitism. (2:33)
Exploring Wisconsin Our Home-We All Work
We All Work - Wisconsin's landscape has always affected the types of work available to its citizens. Conversely, the work people engage in affects the landscape and the people who live there. As technology advances and people can exchange ideas more rapidly, geographical boundaries become less significant, creating more changes in the workplace. This program explores the dynamic relationship among geographical resources, technology, and work, showing students the many choices they can make
How To Make Compare and Contrast Map, Hierachy Map, and Concept Map
Having students create their own graphic organizers with key
words or phrases, images, connections, color, and layout can be a great way for them to develop visual literacy and thinking skills, construct and represent knowledge, and show the connection between their ideas and understandings. In this video three different kinds of graphic organizers are created using Glogsteredu, Prezi, and Powerpoint to make three different types of graphic organizers:
- Compare and Contrast Map
Where does life start? How are we made up? To understand, we must learn about the actual chemistry of life. The atom makes up all molecules, including DNA, RNA, proteins, membranes, and cells. Atoms are the smallest units of matter that retain the properties of a given element. There are four elements that compose almost in your body. They are oxygen, carbon, hydrogen, and nitrogen. Video also discusses protons, electrons, neutrons and how they are charged.
Frequency - Sixty Symbols
You've heard of kilohertz and megahertz, but when things get down to the size of atoms, wave frequency gets to some seriously high values. Video discusses the various types of waves and why there is a difference is what you hear and see. Video is of good quality and is appropriate for high school students. Run time 07:02.
Types of Public Speeches
Types of Public Speeches. Part of the series: How to Pick a Public Speech Topic. Learn about persuasive, informative, and motivational public speeches in this free video clip from a professional public speaker.
Fiscal federalism is the model of spending, taxing, and providing grants in the federal government system. The national government’s primary means of influencing state governments is giving money to states in the form of grants-in-aid. Grants-in-aid have a long history in the United States, dating back to the Confederation period. The nation’s leaders originally designed them to help fund agriculture, land grant colleges, and farm-related education. They grew to encompass many other types of
Types of Differential Equations
Here is a brief look of some of the types of Differential Equations. Video discusses the variable separable equation, the exact equation, and the linear first order type of equation.
What is a Differential Equation?
This clip provides an introduction to Differential Equations. Includes an overview of many different types of algebraic equations and how they are alike and different than differential equations. Discusses derivative form, differential, form, and differential operator form, and how to solve differential equations in these forms.
Jazz - Excerpts from the Ken Burns Documentary-Introduction
Jazz is a uniquely American form of music. It is a combination of all different types of music and cultures. It is an improvisational art that is forever changing, but deeply rooted in the blues. Ken Burns examined its history, and stars, in a documentary which aired on PBS.
This clip is from the introduction to the program. (8:05)
Pollination and Fertilization
Insects usually assist in the fertilization of flowering plants. Fertilization occurs when one sperm nucleus fuses with the egg nucleus. Other sperms form the endosperm by fusing with egg cells. Short video clip discusses pollinators and parts of the flower like the male stigma, female stamen, ovary and embryo. Run time 01:50
3-D animation shows how 5 different types of eclipses occur. Uses models of the earth, moon, and sun. Grades 5-12. 1:43 min.
