Tests in Mr. Barnes’ Class * Multiple choice is 50% of your grade in the class. It is your top priority. * Don’t panic if you can’t answer a question. Just do your best. * Mr. Barnes grades on a curve. (More on this later. ) * When the buzzer rings, at least guess. 25% > 0%. * If you finish MC section early, answer the screen questions. * Do not copy screen questions. Just put q# & answer. * Still have time left? Get a science magazine Read one or more articles On your scratch paper, write whatever comes to mind Do not interact with your neighbors during a test, even if you’re “done”

Do NOT write on the test packets! (If you want to write something, write it on your scratch paper. )

“Form” = Version Your form is indicated by your red test packet #. Your red test packet # should be the same as your seat #. If your test # is this. . . then your form # is this: 1, 6, 11, 16, 21, 26, 31, 36 = Form 1 2, 7, 12, 17, 22, 27, 32, 37 = Form 2 3, 8, 13, 18, 23, 28, 33, 38 = Form 3 4, 9, 14, 19, 24, 29, 34, 39 = Form 4 5, 10, 15, 20, 25, 30, 35, 40 = Form 5

It will be turned in as a separate assignment at the end of the 5 -week grading period.

Student Safety Contract Instructions * Blue or black ink only. This is a legal document. NO PENCIL * Get it right the first time. No changes = no cross-outs, no whiteouts, no erasures (can’t use pencil anyway). * Parents must date their own signature. Do NOT write the date for your parent’s signature, or the whole contract is disqualified. * Print your first & last name neatly in the blank in the ULHC of the backside. * On the allergy question, say what you are allergic to. * Also list if you have any other respiratory weaknesses in the allergy blanks (asthma, etc. ).

Safety Quiz Instructions * Blue or black ink only. This is a legal document. NO PENCIL * You can make mistakes at first, but, as we go over the quiz, you must correct your mistakes. * Any time you change an answer, you must write your initials next to the correction. * You are responsible for making sure that every answer on your safety quiz is correct.

Chemistry Friday 8/26/2016 HOMEWORK: Get a parent to sign your safety contract if you haven’t done so already (hard due date next Friday). WARM-UP: How do you clean up broken glass? STAMPS: none Done with the warm-up? Read 2. 1 & take notes. (It’ll be due pretty soon. )

RE-TAKES in BARNES’ CLASS * WHEN: During lunch or after school. Bring food if you want to. * EFFECT: If you score higher than your previous score, the new score replaces the old score. If you score less than or equal to, no effect. You risk only your time. No worries. * ELIGIBILITY: You must prove that you’ve done the bookwork for all textbook sections covered by the test in question. Bring your bookwork to get your answer document. * MC/SCR: You can do either the multiple choice or the scratch paper or both. Each has its own separate chance of replacing your previous score in that item. * AGAIN? If you want to re-take a re-take, you’ll need proof of preparation beyond the book (tutoring, Quiz Show, etc. ).

Compare and Contrast Gravity and the Electrostatic Force * Both are field forces. Two objects do not need to touch each other to feel each other’s forces. * Both forces get weaker with distance. * The strength of the gravitational force depends on the masses of the two objects, whereas the strength of the electrostatic force depends upon the electric charges of the two objects. * Gravity is always attractive, whereas the electrostatic force can be either attractive (+ -) or repulsive (+ + or - - ). * Gravity is significantly powerful with larger objects, including people and planets, whereas it is insignificant, compared to the electrostatic force, with microscopic objects.

Chemistry Thor’s Day 9/29/2016 HOMEWORK: 4. 3 section assessment, Atom Rules Determination Activity WARM-UP: Why are the atomic masses on the periodic table almost never whole numbers? STAMPS: 4. 3 reading notes & practice problems #15 -24 Done with the warm-up? Get started on the homework.

Why aren’t the atomic masses whole numbers? Reason #1: Proton mass = 1. 007 amu Neutron mass = 1. 009 amu Electron mass = 0. 000549 amu None of these #’s are whole numbers. Reason #2: Atomic masses on the periodic tables are the weighted average of all the atomic masses of the naturallyoccurring isotopes of any given element. Reason #3: The mass defect. When atomic nuclei are assembled out of protons & neutrons, energy gets turned into matter & vice versa (according to e = mc 2).

Oxygen-15 w/a -2 charge: Oxygen must have 8 protons because oxygen is atomic # 8 oxygen-15 has a mass # of 15 mass # = protons + neutrons # of protons = 8, so # neutrons = mass # - # of protons # neutrons = 15 – 8 = 7 neutrons -2 charge more electrons (-) than protons (+) 8 protons, so 8 + 2 = 10 electrons 8 protons, 7 neutrons, 10 electrons. charge = protons – electrons = protons - charge

Oxygen-15 w/a -2 charge: Oxygen must have 8 protons because oxygen is atomic # 8 oxygen-15 has a mass # of 15 mass # = protons + neutrons # of protons = 8, so # neutrons = mass # - # of protons # neutrons = 15 – 8 = 7 neutrons -2 charge more electrons (-) than protons (+) 8 protons, so 8 + 2 = 10 electrons 8 protons, 7 neutrons, 10 electrons. charge = protons – electrons = protons - charge

Chemistry Tuesday 10/11/2016 HOMEWORK: 25. 2 section assessment WARM-UP: What is special about uranium? STAMPS: 25. 2 reading notes, practice problems #’s 7 & 8 Done with the warm-up? Get started on the hw

URANIUM It’s named after Uranus. It’s the largest, naturally-occurring element. All elements with an atomic number larger than uranium must be forced into existence by man, artificially. All of its isotopes are radioactive, being alpha emitters, but that alpha decay is just the first step in a long series of decays, some of which give off beta and/or gamma particles, so don’t assume you can protect yourself from uranium with just a piece of paper. The isotope uranium-235 is “fissile” and can be used to power an atom bomb, trigger fusion in a hydrogen bomb, or power a nuclear power plant.

Just sincere effort. * Be honest about how many points you deserve, but. . . * Don’t agonize too much. Follow the rubric, but go with your gut. * Bubble in pencil in case you change your mind.
