Boundary issues are complicated, and border disputes can cause unnecessary tension between neighbors. We'll show you how to resolve a border dispute with your neighbor.

Tony Buzan is a leading expert on the brain and learning, and inventor of the revolutionary Mind-Mapping technique, which he believes is more efficient than conventional methods of writing notes and ideas. In this film Tony talks about how he developed Mind Mapping and how it can be applied in everyday life.

Great professional tutorial, on how to build an electric motor and how it works.

A clip from Philip Morrison's 1987 PBS program "The Ring of Truth: Atoms" featuring chef Kin Jing Mark making noodles to demonstrate the principle of halving.

Watch these cool patterns created using frequency (A process known as cymatics).

This video shows students how to add fractions with different denominators. To add different fractions you must be able to find the least common denominator.

In these times of identity theft, terrorism, and the TV criminology craze, learn just how genetic fingerprinting occurs.

In this series, Elliott Kwong tells you how to build your very own kaleidoscope using such basic items as pvc pipe, a mirror and a Petri dish. Elliott Kwong talks you through each easy step, from cutting the pipe to breaking the mirror to creating the scene in the Petri dish that will be reflected, inverted and twirled as you look down the pipe for your very own homegrown psychedelic experience.

MIT Professor Arthur Mattuck gives a lecture on how to calculate with ordinary differential equations (ODEs). He also covers the geometrical view of y'=f(x,y), directional fields, and integral curves.

Mr. G plays with chemicals and fire (what a surprise), for a really cool demonstration. An experiment you'll want to try, and probably can try immediately, as all materials (vinegar and baking soda) are likely in your house already. Exothermic reaction and gas displacement at its best!

Anyone that has ridden in a car knows that when the driver speeds up quickly, you are pressed back into your seat, and that when the driver brakes quickly, you are pushed forwards. But what would you think if the force that pushes you backwards was pushing something else forward at the same time?For this experiment, you will need:- a helium balloon- an automobileSit in the back seat, so that you will not disturb the driver.

Ordinary invasive fingerprinting techniques, such as dusting, are prone to damaging evidence. Micro-X-ray fluorescence images fingerprints without touching them. By stimulating atoms to emit signature wavelengths of light, MXRF also provides chemical information -- such as traces of soil or saliva left in the fingerprints -- in addition to the print pattern itself.

A non-Newtonian fluid is a fluid in which the viscosity changes with the applied strain rate. As a result, non-Newtonian fluids may not have a well-defined viscosity. What you need: 1 part corn starch (1cup) 1.5-2 parts water(1.5 cups)

Learn how to use electrolysis - the passing of an electric current through water - to get pure hydrogen and oxygen out of water.

This video is for preschoolers to learn how to do the Diet Coke and Mentos experiment. See how you can involve preschoolers with this cool science experience. If you do not have the resources to do this science experiment live you can watch the Cullen's abc's interactive video for preschoolers titled: "Diet Coke + Mentos for Preschoolers"

Use red cabbage to determine the pH of different common household items. Great experiment for kids. Begin by cutting up a red cabbage. Put in a blender and blend it. Put in a coffee maker and turn it on. After all has come through, turn off the coffee maker and let it cool. Now test it and determine the pH of different household items.

Before we had the calculator and before we had the abacus we had the human brain to complete our math problems for us. Remember that? Well, it seems that few of us do, resorting to calculators on our phone for elementary subtraction problems and multiplication.

What happens when you combine 200 liters of Diet Coke and over 500 Mentos mints? It's amazing and completely insane. The first part of this video demonstrates a simple geyser, and the second part shows just how extreme it can get. Over one hundred jets of soda fly into the air in less than three minutes.

This video explains the science behind a trebuchet. The trebuchet is a medieval machine designed to throw objects at or into castles. This video explains that the gravitational potential energy stored in the raised counterweight is converted into kinetic energy in the projectile. Trebuchets make excellent science fair projects.

Pulleys are simple machines. A knowledge of pulleys can be very useful. This short video shows how to use a pulley to increase the pulling power of a winch. Supports the Force, Work and Energy component of any science curriculum.
