Energy, Matter, and Organization: Nervous System Project

Today marked the beginning of the Nervous System Project.  Students with a grade of a C or higher have earned the opportunity to extra credit in exchange for researching an aspect of the nervous system of interest to them.  As a student-driven project, the purpose is to provide students with the time and space to research topics like depression, Alzheimer’s Disease, Parkinson’s Disease, or any other condition of interest to the student.  The goal is to learn more about the condition and to explore the condition at the system, organ, cell, and molecular level.  Students were encouraged to explore the role of neurotransmitters in their chosen condition.  To help support students, one possible research path might be:

  1. Select a condition that affects the nervous system
  2. Select a neurotransmitter known to be involved in the condition
  3. Research the function of the neurotransmitter and its’ receptor
  4. Research the source of the neurotransmitter (which cells release it?)
  5. Research the neurotransmitter receptor – what is it, and where is it expressed?
  6. Research how the neurotransmitter imbalance may occur
  7. Research available treatment options

Summarize findings in a Google Slides document (then share it with Mr. Swart)

+30 EC for completed project; +5 EC for presentation to class (optional)

Molecular Structure and Properties: Electronegativity and Polarity

We began class with a Crash Course chemistry video about polar and non-polar molecules:

We then worked through the Lesson 43 PowerPoint and followed that with the Lesson 43 Worksheet and accompanying cartoon.  One of the vocabulary terms, dipole, is introduced in the Crash Course video along with the concept of dipole moment.  For more on dipole moment, check out the Khan Academy video below:

Dipole moment: Predicting the molecular dipole moment based on the molecular geometry.

For homework, students are assigned questions 2, 4, and 6.
