Fun Fact:
The one or two letter "abbreviations" you memorize during this unit are actually called element symbols. In alchemy and early chemistry, there were actually pictograph-type symbols for each element. The symbols of ancient alchemy were intended to represent properties of their elements. John Dalton's chemical element symbols from 1803 are more straight forward, and less artistic.

Attendance Policy:
You are expected to be on time, and come to class every day. Lone Peak High School has established an attendance policy to promote increased opportunities for learning and reduction in classroom interruptions. Below is a summary of student attendance expectations. Should a student go over established limits, he/she will lose credit in the class until the issue is resolved by attending Attendance School or a successful appeal to the administration. When students are absent, parents should contact the attendance office (763-7064) to verify the absence within 2 weeks. This is the only way to excuse an absence.
The change of a letter grade to an NC is computer-automated and based on the attendance record. Excusing students via check-in and check-out must be handled through the attendance office on the day of the occurrence. If there is an error with a teacher-generated attendance mark (T or X) the student is responsible to inform the teacher in writing (or via email) within one week of the occurrence in order to have the mark changed.

- Students are allowed four (4) tardies per class each term.
- Students are allowed four (4) excused absences per class each term.
- Students are not allowed any (0) un-excused absences or truancies each term.
- No mark = the student was present in class, and on time
- T = the student was tardy (not seated in the classroom before the bell)
- X = the student was absent (and unexcused) or arrived more than 15 minutes after the bell

Long-Period vs. Short-Period
(April 28-May 1)
April 28 & 29: Long Morning, Short Afternoon
April 30 & May 1: Short Morning, Long Afternoon
Please be aware that some activities/assignments may get bumped from your "short period" day of chemistry to your "long period" day of chemistry.

Day 83-86:
The schedule and assignments for these dates is dependent on your class period's performance on the SAGE test. If scores indicate that more review is needed before the final, your class period will be working on additional review assignments during these days. If scores indicate that your class period is already well prepared for the final, you will be doing other enrichment activities.

I already forgot the instructions I got in class. How do I wash my shirt??
- Make sure the washer is empty.
- Cut the bags & ties off-- touch the shirt as little as possible-- the dye is still active!
- Squirt some (1-2 Tbsp) liquid dish soap (the kind you use in the kitchen sink on pots & pans) DIRECTLY into the machine. (NOT into a dispenser!!) Liquid dish soap (for the sink, not the dishwasher) is essential to the washout-process. It contains a chemical that deactivates the dye.
- Run on WARM as a MEDIUM* load. (If you have a top-loader that gives you the option of starting the water and adding the dish soap before you put the shirt in, that is a fabulous idea.)
- Squirt another dose of liquid dish soap. Run again on warm/medium.*
- If you & your mom are nervous, run it one more time as a rinse.
- Dry normally. Wear proudly. Tell people you have mad chemistry skills.
