Here are the links to the online interactive activities that we explored in class:
Ionic Bonding
Covalent Bonding
Use them to finish your Venn diagram (four statements in each of the three sections) if you need to.

HW#16b -- Friday, Jan. 26
Today's assignment is to finish the 'Counting Atoms' exercise that was printed on the back of Friday's notes sheet. If you don't have your notes with you but still want to complete the HW assignment, here they are:
Count up the atoms for each "reaction" :

HW for Wednesday, Jan. 25
The assignment today is to finish the lab report that we started in class. You had time enough in class to come up with your hypothesis, write down your materials and procedure, and collect your data. It is up to you to complete the last two sections -- the 'Conclusion' and the 'Evaluation' -- before Wednesday of next week. If you need to remember what belongs in these sections, use the 'Golden lab Guide' that you picked up in class a few months ago.
Have the work in your binder under the appropriate day so you can show me during the binder check!

Honors Chem HW assignment for Thursday, Jan. 19th
This is an honors-only assignment; meaning, you do not have to complete it if you are in the regular chemistry classes (1st, 5/6th, 7th, 8th):
1) Read an article in a scientific magazine or science book (3-5 pages) and, after reading the text, identify at least eight words that you did not know the definition for.
2) Write these words down, and then look up and write down their proper definition. NO one-word 'summary'-style definitions; it should be clear that you know the part of speech of the word (ie, verb, noun, adjective) and what it means.
3) Use the word in a sentence of your own making.

HW for this week -- Scientific Method packet
Your HW for this week, which we started on in class on Tuesday, will be due when you come in to class next Monday (Jan. 23). There is no electronic assignments this week, only that you complete, with correct answers, the number of exercises in the packet to give you the grade that you want:
180 pts correct = check (85%)
240 pts correct = checkPlus (95%)
300 pts correct = checkDoublePlus (105%)
As is usual for HW, we will grade your work on the packet together, in class, on Monday. Good luck with your interim tests this week!

HW#15c -- Thursday, Jan. 11th
For each experiment, first list the independent and dependent variables. Then, continue the story by describing an experiment that the person could do. In your description, show that the person got data that ended up supporting their original hypothesis. Use complete sentences!
Ex. -- 'Bowling experiment'
Mr. Kitchen thinks that if he eats a large order of fries before he bowls, that
his score will improve. He believes this because he often feels like his hunger
is distracting him.
Mr. Mikulski writes, as his answer to this question:
"INDEP: eating fries or not eating fries
DEP: score per game
Mr. Kitchens alternates either eating fries or not eating fries before his
bowling games, for the next two months. In the 49 games he bowled without the
fries, his average score was a 148. In the 50 games he bowled with fries, his
average was a 164."
------------------------------------
1) Mr. Mikulski believes that if he makes his students keep a good notebook and check online for their assignments, that more of them will be able to succeed (ie, graduate on time from) the college that they later attend.
2) Alan (a student) is pretty sure that the worse a student's attendance is, the worse their grades will be. He surveyed five students in a small experiment.
3) The security guard thinks that if he starts asking students to tuck in their uniforms nicely ("Could you please tuck your shirt in?") instead of sternly ("Tuck in your shirt, man! You know better!"), that the number of students with untucked shirts will increase.
4) Mr. Horton believes that his weight will decrease if the teachers start getting a weekly basketball game going.
5) Janelle thinks that the Chicago police P.O.D.S. (the flashing blue cameras) make the amount of on-the-street crime that happens further down the block increase.
