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?

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!

DIRECTIONS: Answer the following on your scratch paper if and when you finish working on the multiple choice questions.
1. Vernon claims that he’s created an engine oil additive that keeps cars from crashing. He announces that he’s been using the additive for a year and hasn’t crashed yet. What do you have to say to Vernon?
2. How many manipulated variables should an experiment have? Come up with an example that illustrates why. Do NOT involve rats.
3. Compare and contrast hypotheses, theories, and laws.
NOTE: Do NOT include your warm-up sheet. It will be turned in as a separate assignment at the end of the 5-week grading period.
Student Safety ContractInstructions
* Blue or black ink only. This is a legal document. NO PENCIL
* Get it right the first time. No changes = no cross-outs, no white-outs, 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 QuizInstructions
* 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.
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 AGAIN? If you want to re-take a re-take, you’ll need proof of preparation beyond the book (tutoring, Quiz Show, etc.).
Chapter 01 Packet Grading
Name, period, and date in upper right hand corner of each sheet of paper, or no points for anything on that sheet.
NPD (1) prevents theft and (2) allows return of separated papers.
Unstamped work gets MUCH less points than stamped work.
(1 point/4 full pages)
Packets can be submitted late and/or re-submitted with no penalty. (Not getting stamps is the only lateness penalty.)
Any questions? Any funny red marks you need translated?

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.

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 naturally-occurring 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 = mc2).

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.
