Nine-Weeks Written Portfolio Instructions

The portfolio should have a cover page as the front.  It includes your name and number in appropriate places, and the following items spread vertically across the page:  Science,  the Grading Period,  and the Date.

The second item in your portfolio should be a copy of the Table of Contents.

The rest of your portfolio should contain the assignments for the grading period placed in the order listed by the Table of Contents.

Number each assignment boldly on the top left corner of the assignment.  The numbers should correlate to the numbers on the Table of Contents.

If you are missing an assignment, place a sheet of paper in the portfolio in the place of that assignment.  Put the title of the missing assignment on the paper, along with the appropriate number from the Table of Contents in the appropriate place.

The entire portfolio should be stapled in the top RIGHT corner.

Lagniappe Second Nine Weeks

10/22-23 cogito ergo sum (Latin)–I think therefore I am (Renee Descartes)

10/24-10/27  et cetera (Latin)–and the rest

10/28-10/29  advocatus diaboli (Latin)–devil’s advocate

10/30-10/31    ad hoc (Latin)–for this

11/3-11/ post hoc ergo propter hoc (Latin) — after this therefore because of this (a logical fallacy)

 

11/5-11/6  cum grano solis (Latin)–with a grain of salt

11/7-11/10  caveat (Latin)–warning

11/11-11/12  modus operendi (Latin)–method of operation

11/13-11/14  auto (Latin)–self

11/17-11/18  sub (Latin)–under

11/19-11/20  Biotic (Greek origin) — of or pertaining to life

11/21-11/24  Abiotic (Greek origin)–without life

12/1-12/2  If you can’t explain it simply, you don’t understand it well enough.”  Albert Einstein

12/3-12/4 Vice versa (Latin)–the other way around

12/5-12/8  Epiphany–sudden, striking realization;  Epiphanies are relatively rare occurrences and generally follow a process of significant thought about a problem. Often they are triggered by a new and key piece of information, but importantly, a depth of prior knowledge is required to allow the leap of understanding.

12/9-12/10 Quid pro quo–a thing for a thing

12/11-12/12 Ave Maria–Hail Mary

Atom–smallest particle of matter that can’t be divided chemically

Atomic Number–number of Protons in an atom

Atomic Mass Number–mass of a given atom in Atomic Mass Units;  roughly equivalent to the average number of protons and neutrons in an atom of a given element

Valence Level–Outermost level of electrons in an atom

Ion–an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving the atom a net positive or negative electrical charge

2014-2015 Glossary Journal Page 72

Alpha Particle–consist of two protons and two neutrons bound together into a particle identical to a helium nucleus

Proton–positively charged particle that exists in the nuclei of atoms with a mass of 1.672×10-24 grams (or 1 Atomic Mass Unit)

Neutron–neutrally charged particle that exists in the nuclei of some atoms with a mass of 1.674×10-24 grams (or 1 Atomic Mass Unit)

Electron–negatively charged particle that exists around the nucleus of some atoms

Inference–the act or process of deriving logical conclusions from premises known or assumed to be true

Implicit–understood though not clearly or directly stated

Control–an experiment or observation designed to minimize the effects of variables other than the single independent variable. This increases the reliability of the results, often through a comparison between control measurements and the other measurements

Isotope–variants of a particular chemical element such that while all isotopes of a given element have the same number of protons in each atom, they differ in neutron number
