_________________________________________________________________                                                                                                                       Introduction – Regents Chemistry

“The first day of class should connect to the last day and every day in between!”

 
 This is a course in Regents Chemistry.  The coursework includes the standards from the NYS Board of Regents, Physical setting, Chemistry and some concepts beyond the scope of the NYS standards    
 
Ok so let’s get started on how this course is a bit different than Living environment.
  
1. Chemistry is different in that not all students from Living Environment enter Regents Chemistry. Some fail or decide not to take a more rigorous course.
 
2. Living Environment is more of a vocab course while Regents Chemistry is more of an application course.
 
3. Living Environment is geared to tangible concepts that you experience everyday, while Regents Chemistry is geared to abstract concepts that you cannot see and observe directly.
 
4. Chemistry has a lot of math, especially algebra. 
 
5. Also there is the difference in the scoring rubrics.
 
Living Environment June 2023 Scoring Rubric:  
                                                                                                    
                 Passing =  41 /85 = 48% correct gives you a 65!
                                                  You pass if miss more than half of the questions!!!! 
 
Regents Chemistry June 2023 Rubric:
Passing =  50 /85 = 59% correct gives you a 65!
 Generous but not nearly  as much as Living Environment.
 You also need 9 more correct answers (50 compared to 41) on a harder test to pass!  
 
 
Here is my grading Rubric: 
 
Quarter Grade:       10% average of all Quizzes or Homework assignments (Forms)
                                    30% average of all Labs
                                    60% average of all Tests

Whoosh bottle demo today:

______________________________

Whoosh bottle Demo Notes:
 
Once the I have the alcohol in the gas phase, which has now mixed with the oxygen in the air inside the container I ignite the flammable mixture by providing a spark and the combustion reaction begins. This is an example of an spontaneous reaction that releases energy exothermically, (exergonic reaction).   Here is the chemical change that takes place:
 

                        2CH3OH(l)   +  3O2(g)  →. 2CO2(g) +   4H2O(g)  + Energy                                                                 Alcohol                       Oxygen                carbon dioxide             water                  

                                                                        

                                                                          (l) = liquid, (g) = gas

 Why is oxygen needed??  

                                                                                                                                  jump to:  top

2.  To complete the Safety Form (instructions below)

 

2:  Lab Safety Lesson– Use the Lab safety contract pdf that is posted below to complete this activity or the hardcopy I gave you in class.
 
Regents Chemistry Safety Contract .pdf
View Download  
 
In this activity, you will write the safety rule (just one sentence) ,its number from the safety contract (that I gave you and is posted below),  AND WHERE IN THE VIDEO (: timecode) that is demonstrated in four safety videos.  You need 10 different safety rules and you must use 4 out of the 6 videos. This means if you find 7 in the first video you will need 1 each from the three others to successfully complete the activity.  There are many other combinations but you must use 4 videos and you must have 10 different Safety rules written total.
 
Let me restate: You must find 10 unique safety rules throughout the four of the six videos of your choosing. 
YOU MUST ALSO IDENTIFY BY TIMECODE WHERE IN THE VIDEO THE SAFETY RULE IS BEING 
DEMONSTRATED, DISCUSSED, OR INFERRED.
 
Example of a COMPLETE answer:
                  1: Jefferson High VIDEO – #45. Examine glassware before each use. (3:23)
 
I  know what #’s each video covers and where thus will grade your work based on this accuracy.
 
The video playlist is posted above the lab safety form for your convenience.
