Learn vocabulary, terms, and more with flashcards, games, and other study tools. Record your measurement in 1) millimeters, 2) centimeters, and 3) meters. laboratory table or desk in meters. Click the photograph to view an enlargement. Lab paper . Figure 3. In biology, often we need to describe measurements of length, volume, mass, time, temperature or amount of substance. Lab: The Metric System and Measurement Objectives: At the end of this lab, you should be able to: 1. Introduction: The purpose of this exercise is to practice using the metric system. For example, the number 0.526 becomes 0.5. 38) Measure and record the temperature of ice water. The gram (g) is exactly equal to 1/1000 of the mass of the kilogram (10−3 kg). We usually report the results of scientific measurements in SI units, an updated version of the metric system, using the units listed in Table 1. When measuring time, it is acceptable to use minutes, days or hours when the experiment spans over a significant period of time. The scale in the photograph below has a sensitivity of 0.01 g. The scale can be set to zero by pressing the zero (tare) button on the lower left part of the scale. Water freezes at 0 °C and boils 100 °C by definition, and normal human body temperature is approximately 37 °C. 2. Notice that each of the units in the table above are related to meters by a multiple of 10. It is not 12.3 feet.]. Study Flashcards On Biology: Lab 2 Metric Measurement and Microscopy at Cram.com. We also use fractions or multiples of units in the SI system, but these fractions or multiples are always powers of 10. Science and math come together in this lab/activity! The photograph below shows the end of a meter stick. The exponent for cm is -2; the exponent for um is -6. At your lab table you should have a glass bottle, a small plastic cup, and a test tube.Find and record their volumes in the table below. In almost every facet of modern life, values – measurements – play an important role. Search for: Metric System Conversions. Integrity. The most common circular variables in biology are time of day, time of year, and compass direction. Describe proper usage and measurement techniques for common laboratory tools. Measurements provide the information that is the basis of most of the hypotheses that describe the behavior of matter and energy. Biology I Laboratory Manual. Measure the width of a standard 8.5 × 11 inch page using a small plastic ruler or a meter stick. The arrow points to the bottom of the meniscus in the photograph below. Celsius (°C): unit of temperature; water freezes at 0 °C and boils at 100 °C on this scale, kilogram (kg): standard SI unit of mass; 1 kg = approximately 2.2 pounds, length: measure of one dimension of an object, liter (L): (also, cubic decimeter) unit of volume; 1 L = 1,000 cm3, meter (m): standard metric and SI unit of length; 1 m = approximately 1.094 yards, milliliter (mL): 1/1,000 of a liter; equal to 1 cm3, SI units (International System of Units): standards fixed by international agreement in the International System of Units, unit: standard of comparison for measurements. Molecular Biology. The tables below show similar units based on grams (mass) and liters (volume). To measure lower leg length have your lab partner kneel on a chair with the thigh vertical and the back of the calf at a 90 … Procedure: Measure and record in Table 1 the dimensions (in cm) of several wood blocks. (a) The relative volumes are shown for cubes of 1 m3, 1 dm3 (1 L), and 1 cm3 (1 mL) (not to scale).

Introduction: The purpose of this exercise is to practice using the metric system. Length and Area. Large hanging weights and precision masses with accuracy to 0.01 gram meet your science lab needs. Quickly memorize the terms, phrases and much more. 2015 Biology 110 Laboratory Manual – page 59 Activity # 4. Longer distances are often reported in kilometers (1 km = 1000 m = 103 m), whereas shorter distances can be reported in centimeters (1 cm = 0.01 m = 10−2 m) or millimeters (1 mm = 0.001 m = 10−3 m). 22) How much does the penny weigh in grams? Lab 1 : Orientation One meter = 100 cm.
