Objective Learn how to measure using scientific measurement tools and to observe and identify lab safety rules and procedures.

Stations Measuring Temperature Measuring Volume Measuring Length Measuring Mass Hazards Identification (Safety Scenarios) Lab Equipment Identification Safety Equipment Location More Measurement Practice

Station 1: Measuring Temperature

Equipment: Hot Plate, Water, Thermometer, Paper Towel, Beaker Procedure: 1. Read “Using a Thermometer”. 2. Follow the procedures outlined in “Using a Thermometer” to measure the temperature of the water in beaker. Be sure to place the thermometer back on the paper towel after use. 3. Record your answers on your “Measurement Rotation Lab Answer Sheet”.

Station 2: Measuring Volume

Equipment: Graduated Cylinder and water Procedure: 1. Read “Using a Graduated Cylinder”. 2. Following the procedures outlined in steps two and three of “Using a Graduated Cylinder”, read the volume of liquid in the graduated cylinder. 3. Record your answers on your “Measurement Rotation Lab Answer Sheet”.

Station 3: Measuring Length

Equipment: Ruler, Meter Stick, Toothpick, Textbook, Calculator Procedure: 1. Read using a “Metric Ruler” 2. In what units does the yellow ruler measure? (There may be more than one answer!) 3. In what units does the meter stick measure? 4. Measure and record, in centimeters, the length of the toothpick. 5. Lay the book on the table and measure its length (long side), width (short side) and height. 6. Using the measurements obtained in question #4, Calculate the VOLUME of the book. Be sure to report your answer in the correct units. 7. Using one 2-person lab table and the meter stick, measure in centimeters the length, width and height of the table’s top. 8. What is the AREA of the table’s top? Be sure to report your answer in the correct units. 9. Record your answers on your “Measurement Rotation Lab Answer Sheet”.

Station 4: Measuring Mass

Equipment: Triple Beam Balance, Plastic Stopper, Beaker, Tennis Ball Procedure: 1. Read “Using a Triple Beam Balance” 2. If it is not already, set the triple beam balance to zero. 3. Measure and record the mass of the plastic stopper. 4. Measure and record the mass of the tennis ball. To mass the tennis ball inside the beaker, you must first measure the mass of the beaker and tennis ball, and then measure the mass of the beaker alone. Calculate the mass of the tennis ball alone by subtracting the mass of the beaker from the mass of the beaker and tennis ball.

Station 5: Hazards Identification

Equipment: Lab Safety Symbols Handout, Safety Scenarios Procedure: 1. Read and review the “Science Safety Symbols” handout at this station. 2. Read “Lab Safety Scenario #1” 3. Identify which safety precautions must be taken in order to safely complete the lab investigation. 4. Circle the safety symbols on your answer sheet that go with the precautions that must be observed for this scenario. 5. Repeat the above process for scenarios 2-6.

Station 6: Lab Equipment Identification

Equipment: Test Tube, Test Tube Rack, Pipette, Petri Dish, Bunsen Burner, Microscope, Glass Slide, Beaker, Test Tube Tongs, Funnel Procedure: 1. Observe the equipment at this station. Each piece of equipment is labeled with a letter. 2. Match the letters on the pieces of equipment to the names of the pieces of equipment listed on your answer sheet.

Station 8: More Measurement Practice

Equipment: Various measurement tools. Procedure: 1. Answer the questions on your “Measurement and Rotation Lab Answer Sheet”. 2. Refer to provided information at previous stations if needed.
