The United States Constitution is a relatively brief document that established the foundation upon which the American government is built. It outlines the framework and procedures of the government and sets limits on governmental power. (Video is narrated with slides and speeches.)
The Constitution was founded on several basic principles that help to keep it relevant today. These are the principles of popular sovereignty, limited government, separation of powers, checks and balances
Exchange of Goods With the New World
Pictures of a variety of goods found in the New World, from plants and animals to clothing. In return, European crops and goods were brought to the Americas to exchange. Diseases were also brought to the Native Americans, and large populations were wiped out. AP history lesson. (Video is a set of slides with narration.)
Brown V Board of Education
In 1896, the Supreme Court upheld state racial segregation laws based on the "separate but equal" doctrine in Plessy v. Ferguson. The Court ruled that making a legal distinction between races did not violate the Thirteenth Amendment forbidding involuntary servitude. In addition, the Court did not feel that Plessy violated the spirit of the Fourteenth Amendment, since no rights were to be denied black citizens. Laws requiring the separation of races, the Court declared, do not necessarily imply t
Subtraction With Base 10 Blocks
Base Blocks Subtraction – Use base ten blocks to model separation of groups in subtraction. The user can adjust the problem difficulty by changes the number of digits that appear. Please take a few seconds to wait for this virtual manipulate (that uses a Java applet) to fully load. From Utah State University.

Microbes will continue to break down the fruit skin and flesh until all the water and nutrients are absorbed into the soil below. These nutrients then nourish growing plants.
Fruit Wrappers with Curious George
This video from Curious George introduces students to the importance of skins, peels, and other fruit coverings, which help protect a fruit's precious cargo: seeds. Seeds are a plant's offspring. For plants to survive, they must distribute their seeds in places where they stand a good chance of growing. Fruits are part of a plant's reproductive strategy. The teacher explains to the students that ripe fruit is more attractive to animals. This is important, as fruit-eating animals transport seeds
Biotechnology: Detection of Cell Clones
Professor George Wolfe discusses detection of cell clones in this video from Thinkwell's online Biology series. The video uses lecture format along with notes and illustrations on a board. Run time 08:59.
Reading the Code of Life DNA is central to cell activity, replicating with great fidelity and carrying the information for all proteins. Organisms also regulate the products made from genes in an effort to conserve energy and adapt to new environments.

Jeremy Siegel: Interest Rates Look Stable, but Beware the China Bubble
The U.S. economy may be getting stronger, but that doesn't mean interest rates will go up when the Federal Reserve meets next week on January 31. According to Wharton finance professor Jeremy Siegel, interest rates should hold firm at their current level for quite a while, and "the big question for the market is whether there will be any drops at all this year." He believes there is "a balance in the economy between strength and moderate inflation," and the Fed is unlikely to move interest rates
Cells - Centers for the Week of 8/30/10
Mrs. Matthews students rotate through science centers each week. This week, the class is learning about living things, the parts of a plant and animal cell, and unicellular organisms. Their centers for the week include (1) a video about microbes found on Watchknow called Magic School Bus is in a Pickle (2) three interactive microscope websites on the Whiteboard (3) an experiment with a chicken egg (one large cell) soaked in vinegar to reveal the membrane (4) an art activity where the stud
Biomes Interactive Site
The distribution of plants and animals around the world is anything but random. Instead, it is a result of the interplay of individual environmental tolerances of species and the environmental conditions, especially variations in temperature and precipitation. These interactions result in biomes, the categories into which ecologists organize similar communities of plants, animals, and the environmental conditions in which they live. This interactive resource adapted from NASA features some of th
Semiconductor device technology has transformed our world by making possible supercomputers, personal computers, cell phones, ipods, and much more that we now take for granted. Moore's Law observes that the number of transistors (the basic building blocks of electronic systems) per electronic chip doubles each technology generation. This doubling of transistor density each technology generation has continued since Gordon Moore, one of the co-founders of Intel, made his observation in 1965. It ha
Engineering Nanomedical Systems
This course will cover the basic concepts of design of integrated nanomedical systems for diagnostics and therapeutics. Topics to be covered include: why nanomedical approaches are needed, cell targeting strategies, choice of core nanomaterials, technologies for testing composition and structure of multilayered nanomedical systems, optimizing zeta potentials, design and testing of cell and intracellular targeting systems, in-vivo issues, drug delivery and proper dosing, assessing efficacy of dru
Stock Ownership and The Economy
Students will demonstrate knowledge of the risks and benefits of stocks and make decisions regarding stock ownership.
River Biomes: Tidal Marshes
A one minute video that explains what a tidal marsh is and what value they are to plants and animals. The video needs a lot of reinforcement from the teacher in the form of maps, handouts, and additional graphics that help explain fresh and salt water among other things.
Uses of Plants - Elementatry Science
This video (03:43) relates the many uses of plants from food, to medicine, and medicine.
How Plants Return to an Area Wiped Out by Lava
From Dragonfly TV. Julia and Briana live on the island of Hawai'i, where lots of lava can be found. Lava flows are very unique environments. Even though volcanoes have been erupting here for thousands of years, much of the big island is full of green plants. The girls stopped by the Volcanoes National Park Visitors Center to find out how that could be. Their question to be answered: How do plants return to an area wiped out by a lava flow?
What are all those crazy parts and pieces of a cell? What is the procaryote and the eukaryote? Video explains these two different types of cells.
The Discovery of Penicillin
In this video segment adapted from A Science Odyssey, learn what led British researcher Alexander Fleming to the chance discovery of antibacterial properties of a mold extract he later named penicillin. After treating World War I battlefield casualties, Fleming began searching for compounds that would ward off infections in humans. Returning from vacation in the summer of 1928, he noticed that mold was partly covering one of the agar plates in which he had been growing bacteria, and that the mol
Eric Giler wants to untangle our wired lives with cable-free electric power. Here, he covers what this sci-fi tech offers, and demos MIT's breakthrough version, WiTricity -- a near-to-market invention that may soon recharge your cell phone, car, pacemaker. As the CEO of MIT-inspired WiTricity, Eric Giler has a plan to beam electric power through the air to wirelessly power your laptop or recharge your car. You may never plug in again. Run time 10:13.
