__Instructor Introduction:__ Hi, I’m Leslie and this is my second year teaching at SECA. I love teaching physics with all the hands-on stuff we get to do. Before coming to this school, I developed a physics class for White Bear Lake Alternative and I am eager to get to know and help all of you this year!

__Course Description:__ This is a course on the concepts and relationships in physics. Besides learning more about how the universe works, students will practice analytical thinking skills that apply to everyday life. We will do hands-on activities often and sharpen some math skills used to express how things are connected to each other.

__Topics Covered:__
 * * Forces || * Electricity ||
 * * Motion || * Magnetism ||
 * * Work and Power || * Waves ||
 * * Momentum and Inertia || * Sound ||
 * * Energy and Heat || * Light ||


 * __Grade Distribution:__ || __Grading Scale:__ ||
 * Classwork, “Daily 3”:50% || 100 - 90%A ||
 * Tests / Projects:40% || 89.9 - 80%B ||
 * Participation10% || 79.9 - 70%C ||
 * || 69.9 - 60%D ||
 * || < 60%No Credit ||

__Participation Expectations:__
 * In class (on time, physically and mentally, participating until the end of period)
 * On task (head up, working / participating, not distracting or disrupting others)

__At SECA, we are RHR__ - Code switch to classroom mode || - Honor the bells || - Gather or put away supplies - Keep our room clean orderly || * PEDs & headphones away * End side conversations || - Contribute to your ability || - Monitor your learning * Need notes? * Asking questions / for help || * One-ear quiet music || - Have your brain turned on, contribute || - Advocate for your learning ||
 * We are || Respectful || Honest || Responsible ||
 * Beginning/End of Class || - Help get / keep learning time (minimize disruption or distraction)
 * Lab time || - Gather and return supplies, clean up || - Doing only the activities planned || - Everyone is responsible for keeping everything safe ||
 * Teacher Led or Whole Group Instruction || - Give your attention to the speaker
 * Small Group / Independent Work || - Make class first priority
 * Missing work / contracts || Find appropriate time to discuss progress with me || Be realistic about what you can and will get done || Use schoolview on your own to assess your progress ||

__Minnesota Standards:__
 * 9P.2.2.1: Forces and inertia determine the motion of objects.
 * 9P.2.2.2: When objects change their motion or interact with other objects in the absence of frictional forces, the total amount of mechanical energy remains constant.
 * 9P.2.3.1: Sound waves are generated from mechanical oscillations of objects and travel through a medium.
 * 9P.2.3.2: Electrons respond to electric fields and voltages by moving through electrical circuits and this motion generates magnetic fields.
 * 9P.2.3.3: Magnetic and electric fields interact to produce electromagnetic waves.
 * 9P.2.3.4: Heat energy is transferred between objects or regions that are at different temperatures by the processes of convection, conduction, and radiation.

__MOST IMPORTANTLY:__ Your fellow students are here working consistently toward the goal of learning physics to get credit. Respect is fundamental to helping everyone achieve that goal.
