Welcome to my webpage! My name is Tammy Knight and I am a Science Teacher. I teach Chemistry and AP Environmental Science in 2021-2022.
To contact me, please call 336-570-6161 or email Tammy_knight@abss.k12.nc.us
First and foremost, I would like my students to please enjoy their summer time off!!! 2020-2021 has been an exhausting year and we all need a recharge!!!
However, if you are taking chemistry in the 2021-2022 school year and you are growing a bit tired of simply resting/relaxing (if it is even possible to imagine that!!)....here are a couple of things you can do to get yourself a little ahead before class starts. Notice I said things "you can do for yourself"?
The items below are not requirements ahead of class - I will cover them in class but I have found that it truly does help if you can get a little acquainted with some things ahead of time since for many students, it is all new material from their previous sciences.
1) Make the Periodic Table of Elements your "friend". Please see the current version - Periodic Table
Now that you have been introduced, take some time and get to know a little bit about it - figure out why it is called the "periodic" table, find out who created it, investigate how it is organized. There is a lot of information behind those little square tiles so be curious:
- what is the definition of a "period"? How many periods are present on the table?
- what is the definitiion of a "group"? How many groups are present on the table?
- how are elements in a period related to one another?
- how are elements in a group related to one another?
- do any of the periods have special names? if yes, what are they by period?
- do any of the groups have special names? if yes, what are they by group?
- what determines the identity of an element?
- which elements are solids, which are liquids, and which are gases?
- which elements are metals, which are metalloids, and which are nonmetals?
- which elements are synthetic (meaning man-made)?
- which elements are radioactive?
- are all elements that are synthetic also radioactive?
- are all elements that are radioactive also synthetic?
- which elements exist as allotropes?
- which elements exist as single isotopes?
- why do some elements exist as mixtures of isotopes?
- how can you have different isotopes but the same element?
- which elements are monovalent? which elements are multivalent? what makes an element multivalent?
- which elements are the most reactive? what makes them the most reactive?
As you can see, there is new vocabulary in the questions above - you will hear this vocabulary in class and see it on assignments....so make "friends" with it as well.
You will always be given a periodic table to use on any type of assessment - it will, however, include only the information you saw when you first opened the file above. Imagine what you will see if you know the stuff above!!!
2) Watch the NOVA video "Hunting the Elements" - Video Link
This is a documentary that gives you a preview of many of the things we will talk about in the early days of class - the host is a bit goofy so don't try to watch it all in one sitting. You can watch it in chapters and I would suggest you keep a notepad handy when you watch. Capture some of the things the video talks about/shows you - it may help you remember some of the stuff in the questions for 1)!!!
3) Get your mind prepared for the fact that chemistry involves math!! There's graphs, scientific notation, formulas, word problems, metric system, and something called dimensional analysis (math teachers might call it factor-label method).
None of the math in chemistry is "hard" but, because it is not always presented in the way you might see it in math class, you might disagree. I will be posting more about the math as the summer unfolds but here is a bit of a preview:
- can you create a graph from a table of data?
- can you do a best fit equation for that graph?
- if I gave you a graph of mass vs volume, do you know what you could calculate?
- can you turn 1.45x10^4 into a normal number?
- can you put 0.00234 into scientific notation format?
- if I gave you the formula q=m(cp)(Tfinal - Tinitial), could you rearrange it and tell me what Tfinal is equal to?
- if I gave you the formula P1V1 = P2V2, could you tell me if V gets smaller or bigger when I increase P?
- do you know how many centimeters are in a kilometer? can you calculate it?
- do you know how many centimeters are in a mile? can you calculate it?
- can you do both of the centimeter questions without using a computer?
- do you know how may days are in 2361312 seconds? how many "steps" would you take to explain to someone else how you did that? how would you show me or a classmate how you did that?
I am pretty good at showing students how to do the math - but it is helpful if you have seen/done something similar before we do it in class. You will always be given a calculator to use in class but I do ask you to show your steps. Organization and the thinking (therefore the solving) process is sometimes more important than the final answer!!!
Feel free to reach out with any questions you might have before class begins, and please have a good summer!! I am looking forward to meeting you!!
