Science

Boys’ natural curiosity leads them to ask, “How does this work?”

The passion for answers to that question begins with mixing chemicals for a plaster of paris volcano and catching frogs, but it moves over time toward periodic tables and dissection. Today’s globally interdependent, scientifically-driven world requires a level of scientific literacy significantly more advanced than periodic tables and dissection, however. From atmospheric warming challenges to newly-discovered, genetically-based medical advances, the increasingly complex issues demand the study of not only the scientific facts and processes of each discrete area of biology, chemistry, and physics, but also of the connections to real life applications and scenarios.

Once boys have the necessary foundations in scientific vocabulary, questioning, research, and analysis, they engage in using these skills to address questions at the heart of today’s world dilemmas, such as: How do we develop low-cost, highly effective drugs to combat the social destruction caused by AIDS in sub-Saharan Africa? What are the possible ecosystem harms from the move to genetically modified corn and soybeans in the nation’s food supply?

Real world relevance of the material, authentic application of data and skills, and active engagement are all cornerstones of each science course. Though the exact progression through the courses may be different for each student, the end goal is the same: to not only understand and function in today’s world but to be motivated to engage and improve it.

Courses

Science 610 - 6th Grade Environmental Science

Course Description: 
Sixth Grade Science is a science overview based on learning the scientific method through understanding the environment. Students will explore topics through the lens of the environmental scientists.

  3. Students will gain a basic knowledge of earth science including areas of:
    1. Geology.
    2. Plate tectonics.
    3. Meteorology.
    4. Astronomy.

  3. Group and individual projects, outside of the class, are assigned periodically throughout the year.
  4. Exploratory opportunities are given from time to time for the simple pleasure of finding something of scientific interest in the room for investigative learning. An example would be if we were studying rock types, we would have several rocks available for examination, two or three handbooks and CD-ROMs on rocks and minerals, several books and articles on the subject, four or five computers wired for Internet access, etc. At least three resources are required for greater exposure and diversity of information available. This freedom to choose any interest within the subject matter is always approached with an enhanced enthusiasm for learning.
  5. Labs are generally done in pairs or groups of three, where the students are encouraged to work together to find solutions to a problem or make accurate observations of the task presented them.
  6. Research papers are occasionally given with a minimum of three resources required; the use of Internet technology is usually a must as one of the resources.
  7. Lecture and class discussion following a daily assignment help to re-enforce the lesson and answer questions about any ambiguous aspect in the reading.
  8. Students are encouraged to contribute to class learning by submitting for classroom observation various artifacts which relate to the immediate subject, such as their collection of fossils, as we discuss geological time or sedimentary rocks.
  9. The use of CD-ROMS and interactive CD-ROMS, the Internet, videotape, and slide presentations will help augment learning.
  10. Guest lecturers with specific field expertise offer unique insights to a given subject, such as astronomy (wonderful slides).
  11. Field trips will allow students to experience some earth science features first-hand.

Evaluation:

  1. Short daily quizzes of homework reading assignments reveals whether the student did or understood the material.
  2. Lab opportunities, where students are usually paired, require written assessments of solutions to problems presented.
  3. Students will be given short- and long-range projects, such as constructing a topo model and an accompanying topo map. Detail of the model and accuracy of the map’s representation of the model are important in evaluation.
  4. Research papers are assigned with a minimum of three different types of resources being required. Charts and graphs are suggested for support when applicable.
  5. Students are always encouraged to participate in classroom discussions or to bring into the classroom anything that would interest the class on the current topic. An example would be a student bringing his grandfather’s fossil collection.
  6. Major tests will be given five or six times a semester which demonstrates each student’s understanding of covered material.
  7. A final exam is given at the semester’s end over all the material discussed during the semester. This is a thorough test with objective questioning as well as short essays.
  8. At times, students will have opportunities for self-help and/or extra credit. This is usually for the highly motivated student or for the one who has fallen behind.

Science 820 - 8th Grade Intro to Physics

Course Description: 
8th Physical Science Accelerated is an introduction to the scientific concepts of chemistry, earth science, astronomy and physics, and will go hand-in-hand with the 8th Algebra 1 Accelerated course. Students will learn the techniques of scientific measurement, problem solving methods, and graphing and calculator use early in the course so that these skills might be used and revisited throughout the year. Though many different scientific concepts will be covered throughout the year, there will be a strong emphasis on physics, mainly Newtonian mechanics, for the majority of the second semester. The year will have labs scattered throughout to give the boys hands-on experience with the concepts, as well as to develop an understanding of how much fun they can have studying such topics as chemical compositions and reactions, the make-up of the earth and solar system, and how and why things move the way they do. Grade: 8
