Observation: something noticed or perceived through your senses, such as: seeing, hearing, or touching something directly. "I hear thunder" is an observation. Inference: a conclusion that is developed through evidence, reasoning, or past observations. "Because I hear thunder, it will rain" is an inference.
Inference is using observation and background to reach a logical conclusion. You probably practice inference every day. For example, if you see someone eating a new food and he or she makes a face, then you infer he does not like it. Or if someone slams a door, you can infer that she is upset about something

In simple terms, precision is the term used to see how reliable and consistent the measurement of the experiment is. While accuracy on the other hand checks the closeness of the experiment measurement with the ideal or accepted value.

Accuracy is how close a value is to its true value. An example is how close an arrow gets to the bull's-eye center. Precision is how repeatable a measurement is. An example is how close a second arrow is to the first one (regardless of whether either is near the mark).

The physical quantities for which both magnitude and direction are defined distinctly are known as vector quantities. For example, a boy is riding a bike with a velocity of 30 km/hr in a north-east direction.

A scalar quantity is a quantity that can be defined by its magnitude (or numerical value ) alone. Magnitude has enough information to describe the quantity. For example- distance, speed, time, temperature, etc. A vector quantity is associated with a magnitude as well as direction.

POGIL
Process Oriented Guided Inquiry Learning or POGIL is a student-centered instructional approach. In a typical POGIL classroom or laboratory, students work in small teams with the instructor acting as a facilitator.
A POGIL activity is designed to be used with self-managed teams that employ the instructor as a facilitator of learning rather than as a source of information. A POGIL activity guides students through an exploration to construct, deepen, refine, and/or integrate understanding of relevant disciplinary content.

SI base units
(in the international SI system) a fundamental unit that is defined arbitrarily and not by combinations of other units. The SI base units are the meter, kilogram, second, ampere, kelvin, mole, and candela.

A derived unit is a unit of measurement in the International System of Units (SI) that is derived from one or more of the seven base units.

A metalloid is a type of chemical element which has a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals. There is no standard definition of a metalloid and no complete agreement on which elements are metalloids. Despite the lack of specificity, the term remains in use in the literature of chemistry.

The six commonly recognised metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium. Five elements are less frequently so classified: carbon, aluminium, selenium, polonium, and astatine. On a standard periodic table, all eleven elements are in a diagonal region of the p-block extending from boron at the upper left to astatine at lower right. Some periodic tables include a dividing line between metals and nonmetals, and the metalloids may be found close to this line.

Metalloids lie on either side of the dividing line between metals and nonmetals. This can be found, in varying configurations, on some periodic tables. Elements to the lower left of the line generally display increasing metallic behaviour; elements to the upper right display increasing nonmetallic behaviour.

In modern physics, antimatter is defined as matter composed of the antiparticles of the corresponding particles in "ordinary" matter

Therefore, diatomic means two atoms. The diatomic elements are hydrogen, oxygen, nitrogen, chlorine, bromine, iodine and fluorine. One way of remembering the diatomic elements is by using the acronym HONClBrIF, pronounced honk-le-brif, which includes the elemental symbol for each of the diatomic elements.

Dimensional analysis (also called factor label method or unit analysis) is used to convert from one set of units to another. This method is used for both simple (feet to inches) and complex (g/cm3 to kg/gallon) conversions and uses relationships or conversion factors between different sets of units.

Count the number of significant figures in the decimal portion ONLY of each number in the problem. Add or subtract in the normal fashion. Your final answer may have no more significant figures to the right of the decimal than the LEAST number of significant figures in any number in the problem.
For multiplication or division, the rule is to count the number of significant figures in each number being multiplied or divided and then limit the significant figures in the answer to the lowest count

A phase diagram is a graph of pressure versus temperature that shows the conditions under which the phases of a substance exist. A phase diagram also reveals how the states of a system change with changing temperature or pressure.
The triple point of a substance indicates the temperature and pressure conditions at which the solid, liquid, and vapor of the substance can coexist at equilibrium. Point C is the critical point of water. The critical point of a substance indicates the critical temperature and critical pressure. The critical temperature (tc) is the temperature above which the substance cannot exist in the liquid state.
