Newton’s First Law of Motion Sir Isaac Newton (1642-1727), an English physicist, mathematician, astronomer, natural philosopher, alchemist, and theologian, is one of the most influential scientist who ever lived. In Newton’s work, the Principia was published on 5 July 1687, Newton stated what he believed to be the three universal laws of motion. It is said [...]
Physical Properties of Gases 1. Gases take the shape and volume of their container. 2. Gases will mix evenly and completely when confined to same container. This means that if you mix two or more gases, they form a solution. Air is an example of a solution of gases, which is made up of oxygen, [...]
What is Sound? How is Sound Produced? Sound is a form of energy, just like electricity and light. Sound is produced when something, like a guitar string vibrates (moves back and forth) when strummed. With each back and forth motion of the string, the air around the string is pushed outward on one side and [...]
Luminescence Is Cold Light Luminescence is referred to as “cold light.” This because luminescence is the name given to all forms of visible radiant energy (visible light) due to causes other than temperature. The term ‘luminescence’ was introduced in 1888 by Eilhard Wiedemann. Visible light produced by temperature changes is called incandescence. Luminescence can be [...]

Facts about Butterflies and Moths This list is far from being comprehensive. If you have suggestions, please let me know. Butterflies can see red, green, and yellow. The study of butterflies and moths is known as lepidoptery, and biologists that specialize in either are called lepidopterists. Watching butterflies and moths is known as butterflying [...]
How to Analyze Data and Write a Conclusion Research: The data being analyzed below is about relative density and buoyancy. Relative density is a comparison of densities. Buoyancy refers to something floating in a fluid (gas or liquid). In the diagram, the Box-shaped boats are all floating in water. This means that each boat is [...]
Chameleon Dyes Note: I am revising the following information. I had the opportunity to speak with one of the directors of LCR Hallcrest, a company that makes chameleon dyes. The pencil on the left is covered with Leuco Dye. The pencils in the picture are called chameleon pencils. While chameleons change colors in response to [...]
Phenotype is the outward physical manifestation of an organisms (living things) determined by the genotype, which is the internally coded, inheritable, information called DNA. The dog has long pink hair. Having long hair is a phenotype, but the pink coloring is a dye. The dog’s natural hair color is white. All phenotypes are inherited and [...]
What is the Difference Between Speed and Acceleration? Speed is: how fast or how slow an object is moving a scalar quantity, which is a magnitude measurement only measured in distance per time, such as miles per hour (MPH; mi/hr), or kilometers per hour (Km/h) A speedometer indicates how fast or how slow a vehicle [...]
