Biology- Aug 9-11

Dear Parent(s) or Guardian(s) of an 9th grade biology student,

Welcome to a great year of learning about the beautiful world that surrounds us!  I am excited for a new school year to begin and to join with you in educating your student about the wonders of the world.

My name is Christina Agurcia, and I am originally from Illinois.  I graduated from Lincoln Christian College with a BS in Bible, from Illinois State University with a BS in Biology, and from Adams State University MA in Curriculum and Instruction with a concentration in STEM (Science, Technology, Engineering, and Mathematics).  I am certified by the State of Illinois to teach a wide range of science subjects, including biology, chemistry, and physics.  As well, I have taken graduate education courses in zoology, botany, chemistry, physics, and AP Environmental Science.

I have 14 years of teaching experience in the secondary science classroom, and this will be my eleventh year at Discovery School.  Previously, I taught one year at a private school here in Tegucigalpa and three years at a public school in the United States of America.

This year in biology we will be using the Next Generation Science Standards (NGSS), covering the following topics:

First Quarter-   What is life?    Cell’s Structure and Function     Cell’s Energy

Second Quarter-     Cell Division    DNA and its Functions    Fundamentals of Genetics

Third Quarter-        Plant Structure and Function                     Body Systems

Fourth Quarter-      Body Systems (continued)

The science department divides a student’s grade into the following categories:

Homework/Classwork- 30%                Projects/Labs- 40%                 Tests/Quizzes- 30%

The following supplies needed for biology class are:

15 File Folders               3 Packets of Loose Leaf Paper    1 trifold

1 Packet of Notecards    1 Packet of Notecards                  10 pairs of disposable gloves

Pens or Pencils               Colored Pencils                          Eraser or Correction Fluid

Scissors                         Calculator

This year the 9th grade will be participating in science fair.  The science fair project will be an interdisciplinary project that will be completed during the first semester.  Discovery’s Science Fair will be held on December 1st.

I am looking forward to developing an excellent working relationship with you.  It is important that we keep in close contact about your student’s progress.  Each week I will be updating a blog and calendar, which will have information about the material being covered in class, student activities and homework, as well, as upcoming dates for projects and tests.  The blog is found at https://grade9ds.wordpress.com.  As well, links for the blog are found on the school’s website under the secondary tab.  Students and parents should check the blog each Monday.

All classwork and homework are to be kept securely, using a metal fastener, in a unit portfolio or online in the Google Drive folder assigned for each student.  If work is not presented in the portfolio, it will not earn a grade.  Homework, as listed in class and on the blog, is due by 8:00 AM on the day the assignment is due, whether in a physical or digital version.  For paper work, Students must bring their portfolio, including their work, to my classroom and place it in the bin.  Any work submitted after 8:00 AM will be considered late.  Only excused tardies and absences will be accepted as a reason for turning in work after 8:00 AM.    A student who does not have homework ready at 8:00 AM will be expected to complete that work at snack or lunch time, for 90% of the credit.  Assignments presented one day late are worth 90% of the credit, and assignments presented two days late are worth 80% of the credit.  After this point, no credit will be earned.

Classtime is valuable, and therefore, a student should attempt be at school as much as possible.  However, if a student is absent, he/she is responsible to complete all make-up work.  Make-up work can be found in the “make-up” folder for his or her class.  Any missed notes can be copied from a fellow student.  If a student missed a test/quiz/lab, she/he will need make an appointment to complete the work.  For excused absences, students are given one day to make-up work per each absent day.  For one or two day excused absences, the students should be prepared to take any pre-scheduled test or quiz and submit any large project upon returning to school. For a longer absence, the student will not be required to take a test or quiz on the first two days after returning to school.  For preplanned absences, a student is to notify the teacher in writing previous to the absence (at least 3 days).  The teacher will assign work, giving a schedule to work to be complete.  No credit will be given for unexcused absences or absences due to suspension.

If you need to contact me individually, the best way is through email.  My email address is cagurcia@discoveryschool.edu.hn.  The office will also take messages for me.  If you would like to meet with me, I would be happy to schedule an appointment with you.

If your student has any concerns or does not understand a topic, please encourage him/her to see me.  I am available most days during snack and lunch and can also be before school.

Thank you for entrusting me in joining you in the education of your student!

Sincerely,

Mrs. Christina Agurcia
