Potential & Capacitance in Physic: ORELA Middle Grades General Science Chapter Objectives

The National Evaluation Series (NES) Middle Grades General Science test has replaced the ORELA test in Oregon. Earning a passing score of 228 or higher on this exam helps educators secure licensure that allows them to teach general science in the middle grades classroom.

Topics in this chapter can help you prepare for questions in the physical science content domain of the assessment, which constitutes approximately 31% of the total test. Watch the video lessons or review lesson transcripts to enhance your studies. You can also take self-assessment quizzes and a practice chapter exam that give you access to questions similar in format and content to the 150 multiple-choice questions you'll see on the computer-administered test.
