angle: The distance (usually measured in degrees) between two intersecting lines or surfaces at or near the point where they meet.
application: A particular use or function of something.
concentration: (in chemistry) The measurement of how much of one substance dissolves in another.
Dissolve: To change a solid into a liquid and disperse it back into the original liquid. (For example, solid sugar or salt crystals dissolve in water. The crystals disappear and the solution becomes a completely dispersed mixture of the sugar or salt in water.)
equationIn mathematics, the statement that two quantities are equal. In geometry, equations are often used to determine the shape of a curve or surface.
Soccer field: The field on which American football players play. Because of its size and familiarity, many people use the field as a measure of size. The regulation field (including the end zones) is 360 feet long and 160 feet wide.
gelatin: A substance made from animal collagen, usually from bones or skins of cows or pigs. It is a pale, tasteless powder. It contains proteins and amino acids. It can be used to make fluffy desserts (such as those known as jello). The substance is also used in yogurt, soups, and candies. It can also be used as a base for clear capsules that hold single doses of dry medicines.
Glass: A hard, brittle substance made from silica, a mineral found in sand. Glass is usually transparent and fairly inert (chemically unreactive). Aquatic organisms called diatoms make shells out of glass.
incident: The rate or frequency with which something (usually undesirable) occurs. For example, it might be used to refer to how often new cases of cancer occur in a population, or the rate at which hurricanes occur each year somewhere in the world’s oceans.
Refractive index: A measure of how light passes through matter. Scientists use this index to calculate how much the path of light bends as it passes from one medium to another.
lens: (in physics) A transparent material that can focus or spread parallel rays of light as they pass through it. (in optics) A curved transparent material (such as glass) that bends incident light to focus it at a particular point in space, or one that can mimic some of the light-bending properties of a physical lens, such as gravity. (in social issues) An attitude or viewpoint that helps to focus broader issues.
liquid: A substance that flows freely but has a constant volume, such as water or oil.
mass: A number that indicates how much an object resists acceleration or deceleration. It is essentially a measure of how much material an object is made of.
Optics: An adjective referring to light or vision.
Optics: relating to vision or what is seen.
orientation: (verb to orient) To purposefully position oneself (or the location of another) relative to the cardinal directions (north, south, east, west), the ordinal directions (northeast, southeast, southwest, northwest), or some landmark (the horizon, a particular street corner, a statue, etc.).
vertical: An adjective describing two things that are at about 90 degrees to each other. In the letter “T,” the line above the letter is perpendicular to the line below it.
Physics: The scientific study of the nature and properties of matter and energy. Classical physics describes the nature and properties of matter and energy based on explanations such as Newton’s laws of motion. Quantum physics, a later field of study, is a more precise way of describing the motion and behavior of matter. Scientists who work in these fields are called physicists.
plastic: Any of a set of materials that can be easily transformed or a synthetic material made from polymers (long strings of some component molecules) that tend to be lightweight, inexpensive, and resistant to degradation. (adjective) A material that can adapt by changing its shape and sometimes its function.
Ray: (in mathematics) A line that has a defined endpoint on one side and continues forever on the other side. refraction: The change in direction of light (or other waves) as it passes through some material. For example, the path of light leaving water and entering air is bent, and an object partially submerged in water appears to bend at the surface.
salt: A compound formed by combining an acid and a base (the reaction also produces water). The ocean contains a variety of salts, collectively known as “sea salt.” Common table salt is made of sodium and chlorine.
Solution: A liquid in which one chemical is dissolved in another.
solvent: A substance (usually a liquid) used to dissolve other substances to form a solution.
Speed ​​of Light: A constant commonly used in physics, equal to 1,080,000,000 kilometers (671,000,000 miles) per hour.
square: (in geometry) a rectangle with four equal sides. (in mathematics) a number multiplied by itself or a verb meaning to multiply a number by itself. The square of 2 is 4, and the square of 10 is 100.
theory: (in science) An explanation of some aspect of the natural world based on extensive observation, testing, and reasoning. A theory is also a way of organizing a broad body of knowledge that applies to a variety of situations and explains what happens. Unlike the common definition of a theory, a theory in science is not just a hunch. Ideas and conclusions that are based on theory and not yet based on hard data or observations are called theoretical. Scientists who use mathematics and existing data to predict what will happen in new situations are known as theorists.
Thrust: The force that propels an object forward.
tool: An object made or acquired by a person or another animal and used to serve some purpose, such as reaching for food, protecting oneself, or grooming oneself.
Orbit: The path of a projectile moving through space and time, or the direction of trend over time.
variable: (mathematics) A letter used in a mathematical formula that can take different values. (experiment) A variable that can be changed, especially one that is allowed to be changed in a scientific experiment. For example, if a researcher is measuring the amount of insecticide needed to kill flies, they might change the dose or the age to which the flies are exposed. Both the dose and age would be variables in this experiment.
confirm: (noun: verification) To prove or confirm in some way that a particular assertion or suspicion is true.
vertical: A term used to describe the direction of lines or surfaces running up and down, such as the vertical pole of a streetlight, as opposed to horizontal, which runs parallel to the ground.
wavelength: The distance between the crests or troughs of a series of waves. It is also one of the “standards” used to measure radiation. Visible light, like all electromagnetic radiation, travels as waves and includes wavelengths from about 380 nanometers (violet) to about 740 nanometers (red). Radiation with shorter wavelengths than visible light includes gamma rays, x-rays, and ultraviolet radiation. Radiation with longer wavelengths includes infrared, microwaves, and radio waves.
