Describe proper usage and measurement techniques for common laboratory tools. The abbreviation cc (for cubic centimeter) is often used by health professionals. Measurements provide the information that is the basis of most of the hypotheses that describe the behavior of matter and energy. 2. The standard unit of mass in the SI system is the kilogram (kg). Scientific Measurement of Length Lab. The prefixes used and the powers to which 10 are raised are listed in Table 2. In general, a meter is about the same as 3 feet, but not exactly. Metric to English: 1 liter = 1.056688 quarts = 0.2641721 gallons, English to Metric: 1 quart = 0.9463529 liters; 1 gallon = 3.785412 liters. Identify the standard units of the metric system and make conversions among units. Be Careful. We also use fractions or multiples of units in the SI system, but these fractions or multiples are always powers of 10. Measure the width of a standard 8.5 × 11 inch page using a small plastic ruler or a meter stick. We count calories for a diet, stores measure the percentage of tax on our purchases, and our doctors measure important physiological indicators, like heart rate and blood pressure. In biology, often we need to describe measurements of length, volume, mass, time, temperature or amount of substance. The relative lengths of 1 m, 1 yd, 1 cm, and 1 in. Working in a biotechnology lab requires knowledge of the metric system. It should give a clear idea of what … Not only is it used by scientists throughout the world, but most nations have adopted it as their standard of measurement. A table was constructed to show the organism and their visible characteristics. It was easy to convert … of measurement is the assignment of numbers or symbols to measure an attribute. Uncertainty reflects the systematic and random errors in the measurement. Figure 2. For example, a length of 1000 meters is also called a kilometer because the prefix kilo means “one thousand,” which in scientific notation is 103 (1 kilometer = 1000 m = 103 m). The table below shows the standard unit of length, mass, volume, and temperature in the metric system. In the past, natural units of measurement, such as a "foot", were commonly used. 27) 3 oz = _____ g Round your answer to the nearest 0.01 g. 28) Obtain a 10 ml graduated cylinder (shown below) and add some water to it. When we buy a 2-liter bottle of a soft drink, we expect that the volume of the drink was measured, so it is two times larger than the volume that everyone agrees to be 1 liter. Metric to English: 1 g = 0.0352739 ounces = 0.0022046 pounds, English to Metric: 1 ounce = 28.34951 grams; 1 pound = 453.5924 grams.

Students design experiments in which they place solutions of iodine, starch, and glucose on different sides of a membrane. From the earliest documented days in ancient Egypt, systems of measurement have allowed us to weigh and … Meters, grams, and liters (see the table above) form the basis for larger or smaller units. The negative sign indicates that you must move the decimal point 4 places to the left. In almost every facet of modern life, values – measurements – play an important role. Subtract the two numbers: (-2 - (-6) = 4). The act of measuring: when a measurement is taken this can affect the environment of the experiment. For some experiments, you may need a calculator. Step Four: Pass out the lab packet to the students. The temperature in Fahrenheit can be converted to Celsius using the formula: For example, to convert 60° F to ° C, subtract 32 (=28), multiply it by 5 (=140) and divide it by 9 (=15.56). These measurements will encompass mastering the metric ruler, gram scale, and the graduated cylinder, and thermometer. For example when a cold thermometer is put in a test tube of warm water, the water will be cooled by the presence of the thermometer.

Interactives for Biological Sciences and Scientific Process. The metric system, or international system (SI), is used to describe measurements of many quantities, such as length, mass, volume, and temperature. A graduated cylinder can be used to measure the volume of a liquid. Introduction: The purpose of this exercise is to practice using the metric system. Title: Measurement Lab Date: 8/31/2011 Purpose: The purpose of the Measurement Lab was to learn about the metric system, how to convert between different units, like centimeters to meters, and learn how to make measurements, like length and density. The level or type is the methodology used for taking the measurement. Suppose a doctor prescribes phenobarbital to control a patient’s seizures and states a dosage of “100” without specifying units. The initial units of the metric system, which eventually evolved into the SI system, were established in France during the French Revolution.

DHOULE@BIO.FSU.EDU Measurement--the assignment of numbers to attributes of the natural world--is central to all scientific inference. 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. Every measurement provides both the size or magnitude of the measurement (a number) and a standard of comparison for the measurement (a unit). For some experiments, you may need a calculator. Lab Activity: Measuring with Metric 6 Volume Exercise 1: Practicing measurement accuracy. The exponent for cm is -2; the exponent for um is -6. Notice that each centimeter is divided into 10 mm. The arrow points to the bottom of the meniscus in the photograph below. In the table below are some of the more common SI units used. Measurement and meaning in biology.
