How To: Make an electroscope for static electricty experiments

In this video, learn how to make your own homemade electroscope. An electroscope is an early scientific instrument that is used to detect the presence and magnitude of electric charge on a body and for static electricity experiments. They are easy to make. This electroscope is made from a binder clip and two sheets of plastic (or overhead transparency film), and scissors.

How To: Solve multi-step equations with absolute values

This educational math video describes the steps necessary to solve an equation involving absolute values. "Absolute value" refers to the magnitude of a quantity and is always expressed as a positive number. You can think of absolute value as the distance a number would be from zero if plotted on a number line. Positive 17 and negative 17 both have the same absolute value because both are 17 units from zero on a number line. Because of this, all absolute value problems have two answers, one wh...

How To: Do a similarity transformation in Geometry

In this video the author shows how to do similarity transformations. He says that similarity transformations are used to draw the similar images at a different location and the k value is most important while doing this kind of transformation. He says that a negative k value tells that the copy of the shape will end at the opposite side of the origin to the original shape. He says that a positive k value tells that the copy will lie on the same side of the origin. Next thing about the k value...

How To: Change to a 35mm lens adapter on a video camera

35mm lens adapters cost thousands to buy, hundreds to build, degrade the objective technical quality of your video and make your camcorder an entire magnitude more difficult to use. And they won't make your video magically look like film. Nothing will. On the other hand, by adding selective focusing options to small consumer camcorders, 35mm lens adapters have the potential to produce some absolutely gorgeous images. Watch this video tutorial and learn how to adapt a video camera to a 35mm le...

How To: Calculate probability in "at least one" problems

Calculating probablities can be used to help us make decision. PatrickJMT explains how to calculate probability in an "either A or not A" scenario. The probability of A plus the probability of not A is equal to one. Therefore, the probability of A is equal to one minus the probability of not A ; P(A)= 1 - P(not A). The probability of a major earthquake in San Francisco over a period of time is used as an example. The probablity of an earthquake of a magnitude of 7.5 or greater in San Francisc...

How To: Find and Observe the Garradd Comet

If you haven't seen one, a comet is one of the most spectacular astronomical objects in the sky, partially because it is so close to Earth. At the closest, it is only 1.3 a.u. (194,477,400 kilometers) away from Earth. Comet C/2009 P1 Garradd was discovered by Gordon J. Garradd on August 13, 2009. It never comes closer to the sun than Mars's orbit. Usually, a comet moves fast, but it has stopped moving so fast recently, making it really easy to observe. It can be observed by a telescope or wit...
