    Topics We'll Cover in Honors Integrated Science and Integrated Science*

    Integrated Science courses will follow the Earth and Space Science guidelines of the Next Generation Science Standards (NGSS) within the larger framework of the International Baccalaureate Middle Years Program. To this end, students will continue to develop an understanding of the three disciplinary core ideas and performance expectations that NGSS has outlined. We will look to explain more in-depth phenomena central to the earth and space sciences, and how they relate to life and physical sciences. These performance expectations blend the core ideas of Earth and Space Science with scientific and engineering practices. Crosscutting concepts will support students in developing useable knowledge to explain these ideas across the science disciplines.

    Instructional strategies will be various types of inquiry based lab activities, traditional lecture/guided class discussions, cooperative and independent learning activities (projects), oral/power point presentations, and written reports.

    Tentative Units:

    1. Introduction to science and key review topics

                Includes graphing, scientific method, metric system, svcientific notation, and density 

         2.  Impacts on the Earth's resources

                This unit considers the extraction of water and raw materials to create a bottle and their synergistic impacts on humanity and global ecosystems.

         3.  Global climate change

                A consideration of the factors that regulate the intensity of solar energy that reaches the Earth's surface.

         4.  Earth interactions

                We'll study the earth's lanscape and the processes that have shaped it over geological time.

         5.  Planetary motion

                This unit is concerned with Kepler's laws of planetary motion, especially in regards to the path and orbit of the Apophis asteroid.

         6.  Understanding our universe

                We'll explore the spectral signatures of various stars and evaluate their propensity for forming a black hole.


    *This is a new take on this course. The NGSS represents a major shift in science education and this class will be a work in progress as we begin to realign to this new framework.  This is also our initial year with the IB MYP and some adjustments may be made to satisfy the requirements of both initiatives.


    For all My Classes

    All course materials will be supplemented as often as possible with new material selected from the most-recent scientific literature including Chemical and Engineering News, Chemistry World, and Science


    Personal Responsibilities in All My Science Classes

    1. The school-wide phone policy will be STRICTLY enforced.
    2. Our class will be conducted on the basis of mutual respect; only one person speaks at a time.
    3. Homework and other assignments are to be turned in as soon as you arrive in class; homework is to be completed at home, not during class. 
    4. Arrive at integrated science class along with your homework, notebook, a folder with all appropriate class handouts (including past quizzes and tests), and a scientific calculator. 
    5. Plan to be seated when the bell rings.  Arriving in class after the bell will result in being marked tardy.
    6. Arriving at class 10 or more minutes late will be considered a cut.
    7. A pass is required to leave my class.  Don't leave without one. 
    8. Plan to stop at your locker, the drinking fountain, or the bathroom prior to class.  Once you've arrived, plan to stay until the period ends.
    9. There is a very direct correlation between time spent out of my classroom and a poor or even failing grade.  You miss out on valuable content when you're away from a presentation, a demonstration, or a lab. So...please use the bathroom or the drinking fountain BEFORE or AFTER our class time. 
    10. Any project or lab report that requires printing must be printed prior to arrival in class.  Print at home or in the library before class.  Printers are not available in our classroom.
    11. Remain in your seat until you're dismissed.  Congregating at the door just before the bell rings is a sign of disrespect and won't be tolerated.
    12. Safety regulations will be strictly followed for all laboratory experiments.  Any student who violates the safety procedures will immediately stop working and will receive a failing grade for that assignment.  CT state law and OSHA regulations forbid food or drink in the laboratory classroom.  Water bottles with a secure cap are acceptable.



    Course material will often be presented via PowerPoint presentations.  Students are expected to take appropriate notes.  Frantically copying everything from each slide is impractical; students should strive to record and ultimately assimilate the key concepts.

    Many units will include in-class demonstrations and/or video presentations.  These activities are not provided for entertainment.  Students should expect one or more questions on each unit test that relate to what they've seen.



    Grades will be based on tests, quizzes, lab reports/projects, and homework/class work and computed on a total points basis.

    Each test and quiz will generally contain one extra credit problem.  Students should always make an attempt to solve these questions.  They're meant to be difficult, but far from impossible and never count against your grade.  Partial credit on these problems is possible when the answer is incorrect but a substantial understanding of the problem is apparent.

    There will be no other opportunities for extra credit.


    Late Assignments

    All assignments are expected to be completed on the due date assigned in class.  Late homework and labs will receive 10% off of the earned grade per day partial credit for a maximum of three days.  After three days, late homework will be 50% off the earned grade.   No credit will be given for homework assignments after graded work is handed back or after the unit test on the subject.


    Extra Help

    All laboratory-based science courses, regardless of the level, are inherently fast-paced.  Falling behind is frequently the result of a buildup of unanswered questions.  Students should schedule time with me, preferably by email (rrafka@groton.k12.ct.us), during period 3 (A-days), period 4 (B-days), during CTL, before, or immediately after school (excluding Tuesdays).


    I'm looking forward to a fun and exciting 2018-2019 school year!
