  1. DO NOW: Take back your exit slips from last class; put them aside for now. Take a clicker and take out your Homework – we are using the graphs for our Do Now! • HW: • TEST next class –study! • Lab ANALYSIS due START of class on TUESDAY. Procedure is yours to keep; I only need the Data table from the Procedure stapled to your analysis • OBJECTIVES: • Brief graphing review • All class to finish lab procedure and analysis • If you do not finish the analysis in class, it is due at the START of class on Tuesday. • Remaining time = prep for test

  2. Take out your HW • Any questions about #22-23? Chat with your neighbor or ask a teacher. • Take out your graphs. • You are going to swap papers and analyze someone else’ graphs…WRITE and ANSWER the questions on the next slide. • If you are not sure, conference with a teacher!

  3. Questions to consider as you’re looking at both graphs: • Is velocity ever constant? If so, at what time intervals? • What graphical evidence can you cite that supports your answer? • Is velocity ever increasing? If so, at what time intervals? • What graphical evidence can you cite that supports your answer? • Is velocity ever decreasing? If so, at what time intervals? • What graphical evidence can you cite that supports your answer? • Is acceleration ever constant? If so, at what time intervals? • What graphical evidence can you cite that supports your answer? • Is acceleration ever zero? If so, at what time intervals? • What graphical evidence can you cite that supports your answer? • Is acceleration ever positive? If so, at what time intervals? • What graphical evidence can you cite that supports your answer? • Is acceleration ever negative? If so, at what time intervals? • What graphical evidence can you cite that supports your answer?
