• Summer 2019

     

    Dear Parent/Guardian:

     

    I am looking forward to working with your child in AP Chemistry.  I will strive to challenge your child to achieve his/her potential, to pass on my passion for the subject matter, and to get to know your child’s interests in science.  In order to ensure the best start for everyone next fall, I have prepared a summer assignment that reviews basic chemistry concepts. 

     

    AP Chemistry is an equivalent course to Introductory Chemistry in college.  Taking a college level course in high school is difficult, requires dedication, and is a great investment in your child’s education but they must be prepared to arrive ready to learn in the classroom and on their own.  General or Honors Chemistry is required before you can take AP Chemistry.  It is important for everyone to come to class the first day prepared.  While I review, extensive remediation is not an option as we work towards our goal of being 100% prepared for the AP Exam in early May 2020.  There will be a test covering the basic concepts included in the summer packet during the first full week of school. 

     

    Due to our classes being so short, after school labs will be required once or twice a month.  I will make a calendar ahead of time arrangements can be made for rides, work, or after school activities.  I’m sorry about this, but there just isn’t another choice.  I am trying to make this class somewhat of a flipped classroom in order to accommodate our limited time.  Therefore some assignments will need to be completed prior to coming to class.  This will include but not be limited to PowerPoint’s covering new topics, videos, and practice problems. 

     

    If you wish to track your child’s progress, please use Schoology.  In the fall the students will receive a detailed syllabus of exact requirements. 

     

    Again, I am excited to have your child in AP Chemistry this year.  I have high expectations for both my students and myself.  Please feel free to contact me at any time if you have any questions or concerns about your child’s progress in AP Chemistry class via email (jlwoofter@k12.wv.us) or telephone (304-274-5141).

     

    Sincerely,

    Future AP Chemistry Student,

     

    Welcome to AP Chemistry!  I am eagerly anticipating a great year of Chemistry.  In order to ensure the best start for everyone next fall, I have prepared a summer assignment that reviews basic chemistry concepts.  There is a multitude of tremendous chemistry resources are available via the Internet.  With the ready access to hundreds of websites either in your home or at the local library, I am confident that you will have sufficient resources to prepare adequately for the fall semester. There are few old chemistry textbooks which can be picked up for your reference.

     

    General Chemistry is REQUIRED before you can take AP Chemistry.  It will be important for everyone to come to class the first day prepared.  While I review, extensive remediation is not an option as we work towards our goal of being 100% prepared for the AP Exam in early May 2020.  There will be a test covering the basic concepts included in the summer packet during the first full week of school.  This is basically the first 3 chapters of the book.  You will be tested on general chemistry materials and the summer assignment the first or second week of school.

     

    It is also important that you realize up front how your performance in this course will be measured.  The course grade will mainly depend on your assessment scores, although some lab reports will also be assigned and evaluated.  Do not expect any grade curves or ‘fluff’ assignments this year!  Assessments are administered and graded as if they are AP exams.  Be aggressive in pursuit of knowledge not just the grades.  Prioritize your learning process, do not procrastinate until the last moment, get help in class, participate in class discussions and seek support before grades sink. 

     

    As of now, our class will be meeting fifth period.  Regardless of the extended lunch period, this does not allow much room for labs.  Due to our class length, after school labs might be required once or twice a month.  I will make a calendar ahead of time so can make arrangements, but there just isn’t another choice.  If this is not possible, switch out now because your grade depends on participation in all labs. 

     

    I am trying to make this class somewhat of a flipped classroom in order to accommodate our limited time.  Most learning and ALL reading will be done on you own time prior to coming to class.  This will include but not be limited to PowerPoint’s covering new topics, videos, and practice problems.  If this is not possible for you, switch out now because your grade depends on participation.  I do NOT do a lot of teaching in this class, do NOT take it just because you like me or enjoyed my chemistry class, this is a different animal!

     

    You may contact me by email: (jlwoofter@k12.wv.us) this summer.  I will do my best to answer your questions ASAP.   

     

    I hope you are looking forward to an exciting year of chemistry.  You are all certainly fine students, and with plenty of motivation and hard work you should find AP Chemistry a successful and rewarding experience.

     

    Finally, I recommend that you spread out the summer assignment.  Please do not try to complete it all in the final week of the summer.  Chemistry takes time to process and grasp at a level necessary for success in AP Chemistry.  Remember, AP Chemistry is an equivalent course to Introductory Chemistry in college.  Taking a college level course in high school is difficult, requires dedication, and is a great investment in your education so prepare yourself and arrive ready to learn. 

     

    Have a great summer and enjoy the chemistry,

     

    Ms. Woofter

    • Take notes on the different equipment, accuracy, and its use. You will be quizzed on lab materials and expected to know what instrument or glassware you should be using.  For example if you need to measure volume you would use a graduated cylinder or to be more accurate a pipet or volumetric flask.
