3 All mate-rials lists, procedures, and questions are repeatedso that students can complete a lab in most caseswithout having a textbook on the lab table. Datatables are enlarged so they can be used to easilyrecord data, and all lab questions are reprintedwith lines on which students can write theiranswers. For student safety, all appropriate safetysymbols and caution statements have been repro-duced on these pages. Answer pages for each MiniLab and physics Lab Worksheet are included in theTeacher guide and Answers section at the back ofthis ANDINTERVENTIONS tudy guide :These pages help your students learnphysics vocabulary and concepts. study Guideworksheets typically consist of six pages of ques-tions and exercises for each of the five Student Edi-tion Chapters supported in this book. Items arepresented in a variety of objective formats: match-ing, true/false, interpreting diagrams and data,multiple choice, short-answer questions, and soon. The first study guide worksheet for each chap-ter reviews vocabulary.

As a preview, the worksheets help studentsfocus on the concepts at the time you assign thereading. Students can complete each study Guidesection after reading the corresponding textbooksection. Some students will have more successcompleting the sheets in smaller chunks. For thisreason, the question sets on the study guide pagesare referenced to specific readings in the complete, these worksheets will prove to bean excellent review instrument.

Reinforcement masters are espe-cially helpful for students who require additionalinstruction in order to understand certain con-cepts.

6 Mostof the transparencies contain art or photos thatextend the concepts put forth by those in the text-book. Others contain art or photos directly fromthe Student Edition. There are 120 Teaching Trans-parencies. The ones that support these five StudentEdition Chapters are provided here as black-and-white masters accompanied by worksheets thatreview the concepts presented in the transparen-cies. Teaching Tips for some transparencies andanswers to all worksheet questions are provided inthe Teacher guide and Answers section at the backof this Quiz: The Section Quiz page consists ofquestions or problems that focus on key contentfrom one section of the Student Edition. Each quiztypically includes conceptual items that require awritten response or explanation and items thatrequire problem-solving skills or mathematical cal-culations, where applicable. The Section Quizoffers representative practice items that allow youto monitor your students understanding of thetextbook.

7 Answers to each Section Quiz are pro-vided in the Teacher guide and Answers section at the back of this Assessment: The Chapter Assessmentpages provide materials to evaluate your students understanding of concepts and content from thefive Student Edition Chapters supported in thisbook. Each test consists of six pages of material,which is divided into three sections. Understanding physics Concepts requires students to demonstrate their knowledge of vocabulary and other basic information presented in the chapter. They are assessed through a variety of question types, including matching, modified true/false, short answer/fill-in, and multiple choice. Thinking Critically requires students to use higher-order learning skills. Students will need to interpret data and discover relationships presented in graphs and tables. Other questions may require them to apply their understanding of concepts to solve problems, compare or contrast situations, andmake inferences or predictions.

8 Applying physics Knowledge consists of itemsthat assess students ability to extend their learning to new situations. Assessment is done qualitatively through short-answer questions, and quantitatively through problems. The questions and problems in thissection are more difficult than those presented earlier and generally require more calculations as well as a deepercomprehension of chapter ANDANSWERSA nswers or possible answers to all worksheet ques-tions and activities can be found in order ofappearance at the back of this book.

10 The capacitance depends on the physical characteris-tics and geometric arrangement of the conductors and the insulator. Inthe circuit schematic, the capacitor appears to create an open circuit, evenwhen the switch is in the closed position. However, because capacitorsstore charge, when the switch is closed, charge from the battery will moveto the capacitor. The equal, but opposite charges on the two plates withinthe capacitor establishes a potential difference, or voltage. As charge isadded to the capacitor, the electric potential difference increases. In thislaboratory activity you will examine the charging of several do the charging times of different capacitors vary with capacitance?Objectives Collect and organizedata on the rate of charge of different capacitors.
