How To: Understand diffusion & osmosis

Inside the container we have some water molecules and inside those water molecules we have some sugar molecules. We have more water molecules so in this case the thing which is more of called SOLVENT and the thing which is lesser is called SOLUTE. We can say sugar molecule dissolves in the water. The combination of Solvent and Solute is called the SOLUTION. Diffusion is spreading the molecules from high concentration to low concentration. If we take two containers of water which are joined fr...

How To: Understand saltatory conduction in neurons

This video is a discourse about saltatory conduction in the neurons. According to the author, it begins with the opening of a gate on the membrane of one of the dendrites of a neuron, and positive charge enters through this gate. The positive charge spreads throughout the cell, and gets dissipated as it spreads, so that, by the time it reaches the Axon hillock of the neuron, it is left with very little potential. However, the potential which results from the simultaneous excitement of many de...

How To: Compare fractions.

This video will show those who would like to learn more about math how to easily compare fractions with different denominators using a simple technique. You will be able to compare the fractions to each other by multiplying the numerator of each fraction with the denominator of the other, in a process called cross-multiplication. Keeping the numbers on the proper side of the equation, compare the two products which you receive from each cross multiplication and you will be able to compare the...

How To: Do three balloon science experiments

This video describes how to perform a three balloon science experiment which is a good way for children to learn scientific principles and could make a good science project for school. In this video one will learn key elements of each project and the logic behind the fun. For example in the first experiment one learns about air pressure and how changes from hot to cold cause amazing effects. Overall this video is simple and useful for anyone who would like to teach, entertain or help children...

How To: Make magnets float down a steel tube

Mr.G in the episode 3 of "Summer snow fall" explain the experiment for eddy currents and lenz law by using general house hold items like copper tubes of different dia., 2-neo themium magnets attached together and a ball bearing magnet. At first he took the big diameter copper tube and drop the neo-themium magnets, they fall slowly without touching the surface of the copper tube as they are like freely falling from space with less gravity, for the next time he took small diameter copper tube a...

How To: Create a crazy ketchup packet water bottle experiment

This video displays a very interesting experiment or magic trick involving the concepts of density and buoyancy. You will need an empty plastic bottle with its label removed, some water, and a ketchup packet. Using the concepts of pressure and density, this video demonstrates an interesting experiment which can also double as an interesting party trick; by squeezing a full water bottle, you can cause the ketchup packet to rise and sink in the bottle at your whim. This video is an interesting ...

How To: Use superglue to reveal latent fingerprints

Do you need to check a scene for prints, or are maybe just curious about the techniques of forensic science? In this video, Robert Bruce Thompson from the Home Scientist unravels the mysterious of forensic fingerprinting using common materials that you may already have sitting around in your home right now. Explains and demonstrates the process of superglue fuming step-by-step to reveal latent fingerprints. Includes great tips on how to improve and speed up the process using household products.

How To: Understand the physics of waves: true story of Roswell

In this three-part video, learn about the events surrounding the newspaper article in Roswell New Mexico 1947 regarding crashed flying saucers. The story has to do with nuclear weapons, the second world war, government lies and the movement of sound waves. See how the evnst of Roswell tie in with physics of waves with help from host, Professor Richard Muller of Berkeley University.

How To: Understand the Big Bang theory

Curious about the Big Bang Theory. In this four-part video, learn all you need to know from a great source. Hosted by Professor Richard Muller of the University California, Berkeley, this lecture is part of university's spring 2006 webcasts of "Physics For Future Presidents".

How To: Understand reduction & oxidation in Chemistry

Curious about reduction & oxidation? In this two-part episode of The Science Catalyst hosted by Barry Lambson, the subject of Chemistry, reduction & oxidation is gone over with iron powder and copper sulphate. Oxidation and reduction are heavily related which is why they are both considered "redox reactions". Acids and bases may be thought of as reactions involving hydrogen, or protons, while redox reactions tend to be concerned with electron gain and loss.

How To: Understand Cavernous Sinus Thrombosis

From The Apprentice Doctor, a video regarding "Cavernous Sinus Thrombosis", which means a blood clot in the cavernous sinus. The cavernous sinus is in the base of the brain and contains several nerves, a vein and many other structures. The vein that sits in the Cavernous sinus carries deoxygenated blood from the brain & face and brings it back to the heart. This video shows how to spot Cavernous Sinus Thrombosis in a patient's protruding eyes.
