Video gives all basic information needed to understand warm fronts. Video is of good quality and appropriate for elementary age students, especially for students who are studying weather in science.
Living Band-Aid Beats Like a Heart
Video shows current research in heart tissue structure and repair. Jordan Lancaster and Steven Goldman, researchers from the Southern Arizona Veterans Administration and the University of Arizona, put rat heart cells on a piece of synthetic mesh and within a few days, it started beating.

This video is accompanied by text. "In the late eighteenth century, primitive methods of travel were still in use in America. Waterborne travel was uncertain and often dangerous, covered-wagon and stagecoach travel over rutted trails was uncomfortable, and all types of travel were very slow. Americans were aware that a transportation network would increase land values, stimulate domestic and foreign trade, and strengthen the American economy.
In 1794, a private company completed the Phila
Transformations - Translations and Reflections
This lesson focuses on explaining two types of geometric transformations: translations and reflections. The instructor uses a virtual white board to give examples and chances to select the correct answers.
Tessellation Slideshow of Students Projects
A musical slide show of 7th grade students tessellation projects. There is a definition at the beginning of the video of tessellation and where you can find tessellation. The video then shows how the students took a square and moved it into action using three types of tesselations-translation, rotation, and reflection.
Introduction to Scatter Plots
Brief description about scatter plots and lines of best fit. Various types of scatter plots are briefly described. The video goes over how to analyze data or recognize patters using examples. Some multiple choice problems are presented with answers given.
Learn a Trick to Making Box and Whisker Plots in Excel
See how to create a Box Plot or Box & Whisker Statistics chart
using a Stacked Bar Chart and a Open-High-Low-Close Stock Chart. The video show how to use the QUARTILE function and how to link Chart Labels to cells. The demonstration is done using the software program and the data sometimes is a little difficult on the screen.
Crohns Disease Module 6: Nutrition
Questions addressed in this module include: How important is diet? How can we optimize nutritional intake? Are there foods we should avoid? What types of nutrient supplements should we discuss implementing into our diet?
Solving Rational Equations
In this video, the instructor goes through two examples of solving rational equations. He works through the problems step by step and writes out each step as he explains it. The instruction is quite clear and thorough, making this good practice for these types of equations.
Malaria in sub-Saharan Africa
This video segment adapted from Rx for Survival examines malaria in sub-Saharan Africa, a disease that kills more than one million children there each year. It explains how a deadly parasite, a member of the genus Plasmodium, enters the bloodstream via a mosquito bite and how it multiplies once inside host red blood cells. The video reveals that drug counterfeiting has increased malaria's death toll, and that newer drugs, while more effective than older ones, are too expensive for most Africans
3-D animation explains how the disease affects the body. Discusses how insulin acts on receptors to aide in the entry of glucose into the cells, and how damage can occur to the body. 1:36 min.

A series of short videos that deal with such aspects as types of learning styles and how to learn which is best for various types of learning. There are several short videos in this section. All students should watch this to get ideas on how to improve their study habits.
Volcanoes provide clues about what is going on inside Earth. Animations illustrate volcanic processes and how plate boundaries are related to volcanism. The program also surveys the various types of eruptions, craters, cones and vents, lava domes, magma, and volcanic rock. The 1980 eruption of Mount St. Helens serves as one example.
Intrusive Igneous Rocks
Most magma does not extrude onto Earth’s surface but cools slowly deep inside Earth. This magma seeps into crevices in existing rock to form intrusive igneous rocks. Experts provide a graphic illustration of this process and explain the types and textures of rocks such as granite, obsidian, and quartz. Once again, plate tectonics is shown to be involved in the process.
