Video tutorials on F=ma, FBDs, ionic and covalent bonding

Hi chemistry guys and gals,

I found a few videos on YouTube that do a great job of explaining the two skills that will be on your Test #4 (Monday, Nov. 25th):
Ionic Bonding Intro
How To: Write Ionic Compound Formulas
Covalent vs. Ionic Bonding
How To: Write Lewis Diagrams

Hey there physics guys,

Here are videos that will help you with your F=ma and Free Body Diagrams test (also your Test #4, and also on Monday, Nov. 25th):
Free Body Diagrams
How To: F=ma word problems

HW for this week, which will be a review and help you get ready for the test, will be posted tomorrow (Friday).

best,
Mr. Mikulski

Test #3... only one week left to retake parts you did badly on!!!

It is now Tuesday, a week after you were shown how you did on Test #3 and made to write your scores down into your notes. At that time, you were also all reminded as a class that the time frame in which you can retake parts of the test that you did not pass was TWO WEEKS.

I have only had five students take advantage of test-retaking so far. The last day to retake Test #3 is Tuesday, Nov. 27th. Here are the scores again, in case you were not in class when I gave out this information or you've somehow forgotten how you did:

1st period chemistry
3rd period chemistry
5th period physics
9th period chemistry

Again, the last day to retake part or all of this test is Tuesday, Nov. 27th (just before Thanksgiving break)

HW #11b

HW #11a

Chemistry students, be sure to use this [LINK] to a periodic table if you don't have your notes with you. It will enable you look up what element is being referred to, what its symbol is, and how many valence electrons it has. Remember, the column that the element is found in tells you the number of valence electrons -- from hydrogen's column (one valence electron) to neon's (eight valence electrons).

HW #10 -- make a cheat sheet for Test #3

Your one and only HW assignment for this week is to make a cheat sheet for test #3. Ideally, you would do it in time to have it for TEST #3 on Friday. Here are the topics that will be on each test:

Chemistry:
I) Protons, neutrons and electrons -- counting them in a given element, where they are located in the atom, etc
II) Drawing Bohr models for atoms
III) Determining what kind of ion an atom will form
IV) Determining how ions come together to form ionic compounds

Physics:
I) The difference between position, speed and acceleration
II) Interpreting a position, speed or accel. vs. time graph
III) Solving simple distance, speed and acceleration word problems.

HW #9 -- PLEASE DO THE CORRECT SECTION!

For PHYSICS:

1) Draw a position vs. time graph showing a person walking to school, staying at school for a while, and then walking back home

2) Draw a speed vs. time graph showing a car accelerating from being stopped at a stop sign, and then a few seconds later braking and coming to a stop at another stop sign.

3) Draw the position vs. time graph for the situation in #2.

4) Draw the acceleration vs. time graph for a bowling ball pushed out of a plane at a height of 20,000 ft above the ground. Show the graph all the way to one second after the ball has hit the ground. BONUS if you can label your y-axis EXACTLY (HINT: acceleration due to gravity is a constant 10 m/s/s)

For CHEMISTRY:

Draw the complete Bohr model (with electron energy levels) for each. Then, say exactly what kind of ion the atom can form to undergo ionic bonding... (ex. -- "Na can become the positive ion Na2+"). hou can use the link to a periodic table in the HW#8 post if you need to use one and don't have yours...

1) Magnesium
2) Lithium
3) Phosphorus
4) Chlorine
5) Neon
