Control

 Control

A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable.

 

noun. 

English Language Learners Definition of control. The power to make decisions about how something is managed or done. The ability to direct the actions of someone or something. : an action, method, or law that limits the amount or growth of something

 

There are three main variables: independent variable, dependent variable and controlled variables. Example: a car going down different surfaces. Independent variable: the surface of the slope rug, bubble wrap and wood. Dependent variable: the time it takes for the car to go down the slope.

Mineralogy

Image
 Mineralogy is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical (including optical) properties of minerals and mineralized artifacts.   Silicates, oxides, sulfates, sulfides, carbonates, native elements, and halides are all major mineral groups.   Becoming a mineralogist requires at a minimum a college degree and often postgraduate work. Since most mineralogists work in research or teaching a PhD is the commonest degree that is required. To prepare for this you need to take a college preparatory track in high school.   Georg Agricola a name for German scientist Georg Agricola.   A career in geology is well compensated, with a variety of different career paths and job titles. The main types of careers for geologists are in academia, working for the government (USGS), environmental consulting, oil and gas industry, or mining industry.

Magnetism

 Magnetism   is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Magnetism is one aspect of the combined phenomenon of electromagnetism.   There are six basic types of magnetization: (1) diamagnetism, (2) paramagnetism, (3) ferromagnetism, (4) antiferromagnetism, (5) ferrimagnetism, and (6) superparamagnetism. Diamagnetism arises from the orbiting electrons surrounding each atomic nucleus.   Magnets don't need gravity or air. Instead, their power comes from the electromagnetic field they generate all by themselves. One class of magnets, called electromagnets, does need electricity to work.   Magnets are surrounded by an invisible magnetic field that is made by the movement of electrons, the subatomic particles that circle the nucleus of an atom. The hyperactivity of these electrons gives magnets t...

Retort

 Retort In a chemistry laboratory, a retort is a device used for distillation or dry distillation of substances. It consists of a spherical vessel with a long downward-pointing neck. The liquid to be distilled is placed in the vessel and heated.   Retorts sterilize food after it is sealed in a container by steam or other heating methods. Typically, the sterilization temperatures vary from 230°F/110°C to 275°F/135°C. ... Newer agitation retort processes have reduced cook times, resulting in energy savings and less degradation of the food quality.   The steam-air retort uses a mixture of steam and air, which is added to create an over-pressure in the retort. The air over-pressure allows thermal processing of a wide variety of containers including: glass, metal cans, rigid plastic, and flexible pouches.   It also means like to counter in other references.
