To the Student, Glencoe s 4 in 1 Lab Manual provides you with four separate sections of labs . While each section is unique all the lab activities in this manual require your. active participation You will test hypotheses collect and apply data and dis . cover new information You will use many different skills to make connections. between the lab activities and what you already know . The Laboratory Activities will help you focus your efforts on gathering. information obtaining data from the environment and making observations . You will also work on organizing your data so conclusions can be drawn in a. way that is easily repeated by other scientists , The Inquiry Activities will help you understand that no science works alone . A scientist cannot explain how a plant makes food just by knowing the parts of. the leaf Someone needs to know how the chemicals in the leaf work Knowl . edge of Earth science life science and physical science is needed for a full. explanation of how the leaf makes food Today teams of scientists solve prob . lems Each scientist uses his or her knowledge of Earth science life science or. physical science to find solutions to problems in areas such as the environment. or health , The Forensics Activities provide in depth investigations that deal with DNA .
collecting and analyzing data and interpreting evidence found at a crime or. accident scene You will use your knowledge of scientific inquiry and your. problem solving skills as you learn about forensics procedures You will then. apply these procedures to real world scenarios , The Probeware Activities are designed to help you study science using. probeware technology A probeware lab is different from other labs because it. uses a probe or sensor to collect data a data collection unit to interpret and. store the data and a graphing calculator or computer to analyze the data These. components are connected with a software program called DataMate that. Copyright Glencoe McGraw Hill a division of The McGraw Hill Companies Inc . makes them work together in an easy to use handheld system These labs are. designed specifically for the TI 73 or TI 83 Plus graphing calculators and a. CBL 2 produced by Texas Instruments Inc or LabPro produced by. Vernier Software Technology data collection unit . Getting Started, Science is the body of information including all the hypotheses and. experiments that tell us about our environment All people involved in. scientific work use similar methods for gaining information One impor . tant scientific skill is the ability to obtain data directly from the environ . ment Observations must be based on what occurs in the environment . Equally important is the ability to organize these data into a form from. which valid conclusions can be drawn These conclusions must be such. that other scientists can achieve the same results in the laboratory . To make the most of your laboratory experience you need to continu . ally work to increase your laboratory skills These skills include the ability. to recognize and use equipment properly and to measure and use SI units. accurately Safety must also be an ongoing concern To help you get. started in discovering many fascinating things about the world around you . the next few pages provide you with the following . a visual overview of basic laboratory equipment for you to label. a reference sheet of safety symbols, a list of your safety responsibilities in the laboratory. a safety contract, a reference sheet of SI units, Each lab activity in this manual includes the following sections . an investigation title and introductory section providing information. about the problem under study, Copyright Glencoe McGraw Hill a division of The McGraw Hill Companies Inc .
a strategy section identifying the objective s of the activity. a list of needed materials, safety concerns identified with safety icons and caution. statements, a set of step by step procedures, a section to help you record your data and observations. a section to help you analyze your data and record your. conclusions, a closing strategy check so that you can review your achievement. of the objectives of the activity, Name Date Class.
