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 [...]
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 [...]
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 [...]
How to Challenge Kids With Varying Abilities Notice in the following video that the teachers has kids grouped by abilities. This is not evident until the end of the video when she explains that some groups are expected to build more complicated burglar alarms. During the initial introduction to circuits, groups could be random with [...]
How To Use the Interactive Pendulum Simulator Click the blue weight to run the simulator. You have the option of using one or two pendulums as well as using no friction or a measured amount of friction. There is a mathematical relationship between a pendulum’s length, period, and gravity. While the math may appear [...]
Where to Purchase Black Light Supplies Black lights come in many sizes, the flashlight black light shown as well as phosphors, such as “Glo Germ Powder” and “Glo Germ Lotion ” can be purchased from Amazon.com. The Glo-Germ Lotion and Glo Germ Powder can be used to teach children about the need for washing their [...]
Identify the Motions that Represent Newton’s Laws of Motion The video below will make you laugh. It is a series bloopers made by Bill Dance a famous fisherman. It is definitely a video about motion and every one of Newton’s Three Laws of Motion are repeatedly represented. Kids can watch the video looking for examples [...]
Projectiles Have Two Basic Characteristics: 1. Projectiles are launched into the atmosphere or space. This means that projectiles objects that are hurled, pitched, tossed, thrown, or propelled in some way but do not have any device that keeps them moving, such as an engine. Instead, projectile, as described by Newton’s First Law of Motion, [...]
Why Do Some Heavy Objects Float and Other Heavy Objects Sink? New Terms buoyancy buoyant force density displacement fluid volume Whether an object sinks or floats in a fluid (liquid or gas), depends on several variables: 1. The density of the object in a fluid. (Density is the ratio of the object’s mass [...]
