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.

Condensed Structural Formulas
Structural _________ are cumbersome to write, but simple formulas don’t convey enough information. Graphic formulas or condensed structural formulas are a good compromise. In a condensed ________ formula, each carbon in a chain is written in order along with the number of hydrogens attached to it. Remember that every carbon always has ____ bonds. End carbons always have _____ bonding sites for elements other than carbon, while carbons in the middle of a chain, since they are attached to a carbon on each side, have only _____ bonding sites for elements other than carbon. In the formula CH3CH3CHCH3, it is obvious there is a branch because there are three end carbons, and the middle carbon has only one
hydrogen, so it must be attached to the three other carbons.

Which statement describes the reactions in an electrochemical cell?
Oxidation occurs at the anode, and reduction occurs at the cathode.(Correct)
Oxidation occurs at the cathode, and reduction occurs at the anode.
Oxidation and reduction both occur at the cathode.
Oxidation and reduction both occur at the anode.
Remember the phrase "Red cat and An Ox".
In an electrochemical cell, oxidation occurs at the anode, and reduction occurs at the cathode. Remember the saying, "Red Cat and An Ox."
Based on Table G, which sample, when added to 100. grams of water and thoroughly stirred, produces a heterogeneous mixture at 20.°C?
20. g of KCl
20. g of KI
80. g of KCl (Correct)
80. g of KI
Heterogeneous mixtures are mixtures that do not have a uniform composition.
Heterogeneous mixtures are mixtures that don't have a uniform composition and components are visible. When 80 g of KCl is added to 100 grams of water at 20. °C, not all the KCl will dissolve. Therefore, excess KCl will accumulate at the bottom of the beaker, resulting in a heterogeneous mixture.
Systems in nature tend to undergo changes toward
lower energy and less randomness
higher energy and less randomness
lower energy and greater randomness(Correct)
higher energy and greater randomness
Lower energy = increased stability
Systems in nature tend to undergo changes toward lower energy and greater randomness. Lower energy means increased stability.
Which statement describes the two types of reactions that occur in operating electrochemical cells?
Nonspontaneous reactions occur in voltaic cells, and spontaneous reactions occur in electrolytic cells.
Nonspontaneous reactions occur in electrolytic cells, and nonspontaneous reactions occur in voltaic cells.
Spontaneous reactions occur in voltaic cells, and nonspontaneous reactions occur in electrolytic cells.(Correct)
Spontaneous reactions occur in electrolytic cells, and spontaneous reactions occur in voltaic cells.
Two types of electrochemical cells include voltaic cells and electrolytic cells.
Electrolytic cells utilize a battery to force non-spontaneous reactions to occur, whereas voltaic cells do not have a battery source, as the reactions occur spontaneously.
At which temperature and pressure will a sample of neon gas behave most like an ideal gas?
300. K and 2.0 atm
300. K and 4.0 atm
500. K and 2.0 atm(Correct)
500. K and 4.0 atm
An ideal gas is defined as one in which all collisions between atoms or molecules are perfectly elastic and in which there are no intermolecular attractive forces.
An ideal gas is defined as one in which all collisions between atoms or molecules are perfectly elastic and in which there are no intermolecular attractive forces. A sample of a real gas will behave most like an ideal gas when the temperature is high and the pressure is low (500. K and 2.0 atm).
The absolute index of refraction of medium Y is twice as great as the absolute index of refraction of medium X. As a light ray travels from medium X into medium Y, the speed of the light ray is
halved(Correct)
doubled
quartered
quadrupled
The absolute index of refraction is a ratio of the speed of light in a vacuum to the speed of light in the medium.
The absolute index of refraction is a ratio of the speed of light in a vacuum to the speed of light in the medium. Since the absolute index of refraction of Y is twice as great as X, the speed of the light ray in Y will be reduced to half of what it was in X.
A student claps his hands once to produce a sudden loud sound that travels through the air. This sound is classified as a
longitudinal mechanical wave(Correct)
longitudinal electromagnetic wave
transverse mechanical wave
transverse electromagnetic wave
Sound does not travel in a vacuum.
Sound behaves as a mechanical longitudinal wave.
The amount of electric current through an unknown resistor may be measured by connecting
an ammeter in series with the resistor(Correct)
an ammeter in parallel with the resistor
a voltmeter in series with the resistor
a voltmeter in parallel with the resistor
Current flows through the wire. Voltage is the potential energy difference between two points.
Current flows through the wire. Voltage is the potential energy difference between two points.
To measure current you want the ammeter in the flow (i.e. in series). To measure voltage you connect the voltmeter to the two points (i.e. in parallel).
The amount of electric current through an unknown resistor may be measured by connecting an ammeter in series with the resistor.
An observer counts 4 complete water waves passing by the end of a dock every 10. seconds. What is the frequency of the waves?

If the cross-sectional area of a metallic conductor is halved and the length of the conductor is doubled, the resistance of the conductor will be
halved
doubled
unchanged
quadrupled(Correct)
Two changes to the conductor are occurring here at the same time.
At a given temperature, the resistance of a conductor is directly proportional to its length, and inversely proportional to it cross-sectional area: . Doubling the length of a conductor doubles its resistance. Halving the cross-sectional area of the conductor also doubles its resistance. The combined effect is a quadrupling of the resistance.

Condensed Structural Formulas Structural formulas are cumbersome to write, but simple formulas don’t convey enough information. Graphic formulas or condensed structural formulas are a good compromise. In a condensed structural formula, each carbon in a chain is written in order along with the number of hydrogens attached to it. Remember that every carbon always has four bonds. End carbons always have three bonding sites for elements other than carbon, while carbons in the middle of a chain, since they are attached to a carbon on each side, have only two bonding sites for elements other than carbon. In the formula CH3CH3CHCH3, it is obvious there is a branch because there are three end carbons,
and the middle carbon has only one hydrogen, so it must be attached to the three other carbons.

The ground state electron configuration is the arrangement of electrons around the nucleus of an atom with lower energy levels. The electrons occupying the orbitals of varying energy levels naturally falls towards the lowest energy state or ground state.
An excited state configuration is a higher energy arrangement (it requires energy input to create an excited state). Valence electrons are the electrons utilised for bonding. These are the 'outer' electrons (i.e. the electrons which travel furthest away from the nucleus) and the highest energy electrons.

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.

Reminders to help you.
Velocity is the displacement divided by the time. Both have direction that must be stated!
Displacement is an objectâs change in position. The other way to find it is if you have an initial velocity of 2 m/s north and a final velocity is 4m/s north, the average velocity is 3m/s north. The middle value. You add them up and divide by 2.

"I am not remotely interested in just being good." Vince Lombardi
"Don't measure yourself by what you accomplished, but by what you should have accomplished with your ability." John Wooden
You undoubtedly will have questions and concerns that we will work out as we go along. Organize your work and start a new section with your physics questions. I will eventually call students and go over their individual questions, which should be able to clear up any confusion. I feel that the one to one approach will make it easier to answer your questions individually, and give undivided attention to each student.
Some things to remember:
-You must keep your work organized so when we communicate with each other (whether by email, text or phone conversation) I will know exactly where you are in the assignment.
-You must have your questions ready to go. This will enable me to help you in the best way possible.
-As always, we will continue with Castle Learning Assignments.
-Homework assignments and the Classwork, Notes and Review will be worked out as we go along.
-The note packets are all posted on my quia website. Just look and follow the links. As we go along, we will work out how all the work will be turned in and graded.
My Website will be our HOME BASE!
