Identifying Laboratory Equipment
Identifying Laboratory EquipmentIntroductionScientists use a variety of tools to explore the world around them. Scientific tools are very important in the advancement of science. The type of tools scientists use depends on the problems they are trying to solve. A scientist may use something as simple as a metric ruler to measure the length of a textbook. In a different investigation, the same scientist may use a thermometer to measure the temperature of a unknown boiling liquid. In this activity, you will identify pieces of laboratory equipment likely to be used in a chemistry laboratory. You will also learn the function of each piece of laboratory equipment.ProblemWhat are the names and functions of some of the pieces of laboratory equipment found in a typical chemistry laboratory?Pre-Lab DiscussionRead the entire packet before answering the questions.1. What types of measurements might you need to make in the chemistry laboratory?2. What types of equipment would you need to make measurements in the chemistry laboratory?3. Why are several types of glassware marked for measuring?4. How might glassware be used differently?MaterialsHolt Chemistry TextbookLaboratory equipment (for modeling and demonstration)Procedure1. Look at the drawings of the laboratory equipment in Figure 1 below. In the chart that follows, write the name of each piece of laboratory equipment under the column titled “Identify It”.2. Carefully inspect the different types of laboratory equipment that have been set out by your teacher. In the space provided, draw the item and record the function of each piece of laboratory equipment.Equipment Word BankEvaporating Dish, Mortar and Pestle, Test Tube Holder, Apron, Clay (Pipestem) Triangle, Test Tube Rack, Ring Stand, Forceps, Stir Rod, Metric Ruler, Beaker, Graduated Cylinder, Pipette, Watch Glass, Funnel, Thermometer, Erlenmeyer Flask, Scoopula, Test Tube, Crucible, Beaker Tongs, Ring Clamp, Bunsen Burner, Wire Mesh with Ceramic CenterFigure 1CDEFBA INCLUDEPICTURE "" \* MERGEFORMATINET INCLUDEPICTURE "" \* MERGEFORMATINET IHLKJG HYPERLINK " INCLUDEPICTURE "" \* MERGEFORMATINET OPRMNQ INCLUDEPICTURE "" \* MERGEFORMATINET INCLUDEPICTURE "" \* MERGEFORMATINET INCLUDEPICTURE "" \* MERGEFORMATINET UWVXTS INCLUDEPICTURE "" \* MERGEFORMATINET INCLUDEPICTURE "" \* MERGEFORMATINET INCLUDEPICTURE "" \* MERGEFORMATINET INCLUDEPICTURE "" \* MERGEFORMATINET Identify It (What is the piece of equipment called?)Draw It(Draw a picture of the tool)Explain It (What is the function of the piece of equipment?)A.

Which laboratory tools can be used to handle small objects or chemicals?2. Which laboratory tools are useful when heating a liquid?3. What tool or tools would you use to make each of the following measurements? What is the unit of measurement for each tool? (Tools may or may not be listed above.)A. amount of milk in a small glass: __________________________________________B. length of a maple leaf: _________________________________________________C. temperature of the water in a lake: ________________________________________D. mass of a sea turtle: ___________________________________________________4. How do laboratory tools improve the observations made by a scientist?Going Further:Examine other types of laboratory equipment that you will be using in the chemistry laboratory. Try to determine the function of each piece of equipment.BuretCrucible TongsFlorence FlaskTest Tube Clamp ................
