Welcome to Honors Chemistry!! Happy Summer, future chemistry students!! I’m thrilled that you are signed up for Honors Chemistry next fall! I LOVE teaching chemistry and I can’t wait to start the year with you as we embark on our journey to understand the natural world at the molecular level. Chemistry is different from biology for many reasons. For example, we will dive deeper into matter beyond what can ever be seen with microscopes; we will explore atomic behavior and discuss just how scientists learned about atoms when they cannot be seen. Secondly, whereas biology focuses on living organisms, we will expand your view to what generally makes up matter - living or nonliving. Thirdly, chemistry will involve more problem solving than biology - some may say that your calculator will become your best friend! It will be an exciting time when you can put those analytical skills learned in your math classes to work! Our goal in chemistry will be to ultimately understand matter on three levels: the macroscopic (visible) behavior we should expect, the microscopic (atomic level) behavior that causes what we observe, and the mathematical/symbolic way we represent relationships involved in that matter. While I hope you spend most of the summer relaxing, soaking up some VItamin D, and enjoying time with friends and family, I want you start the year in Honors Chemistry in the strongest way possible. In order to help you feel comfortable with the material at the beginning of the year, I am asking you to review and refresh some skills that have been covered in previous classes - mainly scientific notation and the basics of the metric system. I know that you learned scientific notation in middle school math, but since you often don’t express numbers in this format, you may have forgotten the particulars. It is called SCIENTIFIC notation for a reason. We need it in science! I also know that you have been instructed in the metric system in past science courses, but since our everyday use is based on the English system, you may need to review the metric system so you have the ability to use it successfully every day in science. We will work with both of these concepts right away in Honors Chemistry, so you will get lots of practice when the school year beginsI just need to you refresh the fundamentals so you are confident in the first unit. To give you convenient resources for your review of scientific notation and the metric system, I’ve included some handouts. You are also welcome to look for videos/other explanations or practice onlinethere is a wealth of information on these topics out there! Please also don’t hesitate to send me an email if you have a question ([email protected] ). While I won’t check my email every day, I will check every couple days throughout the summer. This summer assignment is intended to refresh some potential “rusty memory” so that your year starts well-oiled in confidence and comfort. It’s okay if you don’t remember somethingjust take some time to practice. By no means do I want you to panic if you struggle a little with either of these topics.. Reach out to me via email and make notes on your assignments about where you are struggling and we’ll get you straight when school begins. The summer affords you the time to review these topics at a relaxed pace. Ask questions if you have them! See you at the end of August! Can’t wait to meet you! - Ms. Shirey

Welcome to Honors Chemistry!!  Happy Summer, future chemistry students!!  I’m thrilled that you are signed up for Honors Chemistry next fall!   I LOVE teaching chemistry and I can’t wait to start the year with you as we embark on our journey to understand the 

natural world at the molecular level.  Chemistry is different from biology for many reasons.  For example, we will dive deeper into matter beyond what can ever be seen with microscopes; we will explore atomic behavior and discuss just how scientists learned about atoms when they cannot be seen.  Secondly, whereas biology focuses on living organisms, we will expand your view to what generally makes up matter - living or nonliving.  Thirdly, chemistry will involve more problem solving than biology - some may say that your calculator will become your best friend!  It will be an exciting time when you can put those analytical skills learned in your math classes to work!  Our goal in chemistry will be to ultimately understand matter on three levels:  the macroscopic (visible) behavior we should expect, the microscopic (atomic level) behavior that causes what we observe, and the mathematical/symbolic way we represent relationships involved in that matter.   While I hope you spend most of the summer relaxing, soaking up some VItamin D, and enjoying time with friends and family, I want you start the year in Honors Chemistry in the strongest way possible.  In order to help you feel comfortable with the material at the beginning of the year, I am asking you to review and refresh some skills that have been covered in previous classes - mainly scientific notation and the basics of the metric system.  I know that you learned scientific notation in middle school math, but since you often don’t express numbers in this format, you may have forgotten the particulars.  It is called SCIENTIFIC notation for a reason….  We need it in science!  I also know that you have been instructed in the metric system in past science courses, but since our everyday use is based on the English system, you may need to review the metric system so you have the ability to use it successfully every day in science.   We will work with both of these concepts right away in Honors Chemistry, so you will get lots of practice when the school year begins…  I just need to you refresh the fundamentals so you are confident in the first unit.  To give you convenient resources for your review of scientific notation and the metric system, I’ve included some handouts.  You are also welcome to look for videos/other explanations or practice online…  there is a wealth of information on these topics out there!  Please also don’t hesitate to send me an email if you have a question ([email protected]).  While I won’t check my email every day, I will check every couple days throughout the summer.  This summer assignment is intended to refresh some potential “rusty memory” so that your year starts well-oiled in confidence and comfort. It’s okay if you don’t remember something…  just take some time to practice.  By no means do I want you to panic if you struggle a little with either of these topics..  Reach out to me via email and make notes on your assignments about where you are struggling and we’ll get you straight when school begins.  The summer affords you the time to review these topics at a relaxed pace.     Ask questions if you have them!  See you at the end of August!  Can’t wait to meet you!

 HONORS CHEMISTRY SUMMER ASSIGNMENT 

  

1. Review Scientific Notation (review from Middle School Math) - In chemistry, we work with numbers that range from extremely LARGE (ie - How many atoms are contained 

in your body?), to extremely SMALL (ie - How much does an atom weigh?), to everything in between (ie - What volume of water should be used for the experiment?).  We will therefore need to have solid ability to express numbers in scientific notation and be able to do mathematical manipulations with numbers expressed in scientific notation. 

- Scientific notation is based on POWERS OF 10.  You should review this concept until you are comfortable with powers of 10 and doing mathematical functions (ie - adding, subtracting, multiplying, dividing, squaring, etc). 

ASSIGNMENT: (a) Read and work through the review material on scientific notation that you received with this 

assignment.  Do the practice problems throughout the chapter and check your work with the answers given.  The only way to know you if understand is to do the practice and check your work!  You may also consult online tutorials to help you get reacquainted with scientific notation. 

(b)  Complete the Scientific Notation problems attached to this document (They are due on the first day of school, so please bring it when school begins). 

 2. Review the Metric System / Calculations with Units  (review from 8th Grade Science and 

Biology) - In Honors Chemistry, like all other science classes, we will use the metric system for all of our 

measurements.  You have been introduced to this measuring system in previous classes, and should review the fundamental base units and prefixes this summer.  When we convert in the metric system, we will focus on using powers of 10 instead of simply moving the decimal (since we will work with numbers that are so small or so large that it is inconvenient to write it in expanded form).  I will explain using powers of 10 to make conversions with you when school begins; however, you should review the basic system and how to do simple conversions via moving the decimal. 

- Please prepare to come on the first day of school with the prefixes and their corresponding meaning memorized. 

- Since all numbers in chemistry represent measurements, units will be required with all numbers and will be involved with all calculations.  Please prepare to school comfortable doing calculations with units. ASSIGNMENT: (a) Read and work through the review material on the metric system/calculating with units  that 

you received with this assignment. Do the practice problems throughout the chapter and check Your work with the answers given. You may also consult online tutorials to help you get reacquainted with metric system.  [NOTE: Section 2.3 of this chapter provides hints to help you memorize; this section is optional.] 

(b)  Complete the Metric System problems attached to this document (Bring them with you 

Page 3: Welcome to Honors Chemistry!! · QWERY keyboards (which are also not allowed on the PSAT, SAT, etc). **If acquiring any type of scientific calculator to use for Honors Chemistry is

when school starts - they are due on the first day of school). (c) Memorize the prefixes mentioned on the Metric System worksheet and their corresponding 

meanings.  Be prepared for a quiz on these prefixes at the end of the first week.  

3. Review your Algebra Skills (review from Algebra I) - We will set up algebraic expressions in almost every unit in Honors Chemistry.  You should practice solving 

for “x” in different algebraic problems.  If you get stuck on the assignment or feel unsure about how to solve for “x” you should first consult online sources to review.  If you’re still stuck, simply complete as much as you can and be sure to ask me for assistance during the first week of school. 

- ASSIGNMENT: (a) Complete the Algebraic Skill review worksheet and bring it with you on the first day of school.  You 

may use a calculator.

A Note About Calculators!   A scientific or graphing calculator will be necessary for Honors Chemistry.  You should plan to acquire one by the beginning of the second week of school. ( I’m letting you know early so that you can look for deals this summer IF you choose to).  For  summer work , instead of using a calculator, you can google “scientific calculator” for an online version of a scientific calculator OR go to https://www.desmos.com/scientific, OR use your smart phone’s calculator.   

- A scientific calculator can be purchased online or at Walmart/Target/Staples, etc.  They are usually $10-$15.  

- Those of you who are concurrently enrolled in Algebra II will be asked to obtain a graphing calculator for the Algebra II course.  Those of you enrolled in Geometry will be asked to obtain one for your math class when you get to Algebra II, although you will NOT  be allow to use a graphing calculator in Geometry. 

 - I recommend that you acquire a graphing calculator for Honors Chemistry since everyone will eventually need them 

for Algebra II anyway and we will use them in chemistry; however, a scientific calculator (with exponents, logarithms, etc) will work also for chemistry.  Many students find the functionality of a graphing calculator useful for chemistry, but you can combine a scientific calculator with DESMOS online program for this course if you prefer. 

- While graphing calculators are a bit of an investment, LOTS of places have sales for back-to-school.  Keep your eyes peeled for ads this summer!  Supplies can be limited when school starts and everyone is rushing to get one.   

- Consider asking an older friend or relative who is done with theirs if you can borrow or purchase a used graphing calculator to save money. 

- Guidelines for graphing calculators: - The math and science departments are mainly familiar with Texas Instruments; other brands (ie - 

Casio) have similar functions, but you may have a figure things out a bit more on your own. - TI-84 Plus CE / TI-84 Plus / TI-84 / TI-83 versions of Texas Instruments are recommended.  You 

will not be allowed to use the “fancy” graphing calculators that connect to the internet or have a QWERY keyboards (which are also not allowed on the PSAT, SAT, etc). 

 **If acquiring any type of scientific calculator to use for Honors Chemistry is problematic for you, please speak to me privately when school starts and I will allow you to borrow one.
