Name: _________________________________ Period: _____ Unit 1: Introduction to Physics and the Physics Toolkit The Big Idea(s): The ability to properly measure and represent measurements is a critical life-long skill necessary for the study of physics. The language of physics is mathematics and is used to analyze data, construct models, make concise statements about nature, explain how concepts are related to each other, and discover new relationships among physical quantities. Plan Essential Questions: How do we properly measure and represent measurements of time and length? How do I apply my knowledge of mathematics and common metric prefixes to perform arithmetic operations and properly represent the answer? How can I apply my knowledge of measurement and mathematics to define and calculate the average speed of a moving object? Check off the study skills you PLAN to use this unit in the first column below Check off the study skills you USED to move from ? or ! to in the second column. Use the blank spaces to create your own study skills. Used Plan Review labs, notes, packet and activities. Use the calendar to make sure you review everything. Have a family member or friend quiz me orally. Meet with my teacher in the morning for extra help. Complete and review (by reworking problems) all problem sets, check-ups, practice tests, and quizzes. Use the Objective Checklist throughout unit to assess understanding. Used Re-read or review all assigned readings (textbook, handouts, online). Find a study buddy from Physics who understands the material and I can work well with. Use the Objective checklist as a Study Guide for end of unit test/quiz. Start studying early! (Not just the night before the test.) Ask and answer questions during class. Use the learning target checklist as your personal guide to assess your level of readiness for quizzes and the unit test. Circle the descriptor that best describes how you feel about your mastery of each objective. NOTE: IF IT IS NOT A , YOU PROBABLY ARE NOT READY FOR THE QUIZ / TEST!!!!!
