View Homework Help - Measurements in Biology lab workbook exercises from BIO 025 at Olivet Nazarene University. Not only will this be confusing to the medical professional giving the dose, but the consequences can be dire: 100 mg given three times per day can be effective as an anticonvulsant, but a single dose of 100 g is more than 10 times the lethal amount. When converting smaller units to larger units, the decimal point is moved to the left. The SI unit of temperature Celsius (°C). Integrity. 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. The experiment of flow meter measurement is conducted to introduce the students to the three different types of commonly used flow meter in the industry. We’ll also learn about measurement uncertainty, a separate but related topic that is central to our success in science experiments and The number 0.4382251 rounded to the nearest 0.0001 is 0.4382. Lab 7: Respiratory Systems Breathing is an involuntary event. Houle D(1), Pélabon C, Wagner GP, Hansen TF.

Scientific Measurement of Length You must subtract these two number to determine how many places to move the decimal point. A cubic centimeter (cm3) is the volume of a cube with an edge length of exactly one centimeter. Record these measurements in Data Table 1. Glossary of Scientific Measurements and Laboratory Measurement Tools Terms and Terminology. Figure 2. Measurements provide the information that is the basis of most of the hypotheses that describe the behavior of matter and energy. Unformatted text preview: Lab Report Page 1 BioLab3 Lab Report 1 Measurement Student Name Jasmine Goins I Length Measurement EXERCISE 1 Measuring length using the meter A dime and a meter stick have been used to determine the following How thick is one dime 1 mm 10 mm How thick would a stack of one hundred dimes be 100 mm How thick would a stack of one thousand dimes be 1000 mm … In biology lab reports, the introduction is like a framework for the whole text and it shows that you fully understood the topic and the purpose of the experiment. To find the precision, you basically take the smallest unit on your measuring device, and add a decimal place (the uncertain digit). The metric system uses standardized units of measurement for length, mass, and volume, ensuring measurements are reproducible and easily made. The metric system: The internationally agreed to measurement system that is, with the exception of the United States, the only system of measurement that is used. One meter = 100 cm. Activity of the enzyme, catalase [which catalyzes the reaction 2H2O2(l) → 2H2O(l) + O2(g)], is … The abbreviation cc (for cubic centimeter) is often used by health professionals. The original standards for the meter and the kilogram were adopted there in 1799 and eventually by other countries. Units, such as liters, pounds, and centimeters, are standards of comparison for measurements. One kilogram is about 2.2 pounds. Every measurement provides both the size or magnitude of the measurement (a number) and a standard of comparison for the measurement (a unit). The LibreTexts libraries are Powered by MindTouch® and are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot.

Biology Lab Measurement 1 Instructions for Lab Read the entire lab … Click Start, Programs, Accessories, Calculator). 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. It is not 12.3 feet.]. Step one, Measure 17 ml of RED water from the beaker and pour into test tube A. Students design experiments in which they place solutions of iodine, starch, and glucose on different sides of a membrane. Introduction: The purpose of this exercise is to practice using the metric system. These measurements will encompass mastering the metric ruler, gram scale, and the graduated cylinder, and thermometer. There are many different measurement systems you can use to analyze objects in a laboratory, and this test/worksheet combo will help you test your understanding of the metric system. The most common circular variables in biology are time of day, time of year, and compass direction. Notice in the table above that one milliliter (ml) equals one cubic centimeter (1 ml = 1 cc or cm3). Lab. Measurement uncertainty: every measuring device has a range in which the measurements are accurate. Exponents are useful when writing numbers that are very large or very small. Accurate observations of phenomena are one of the keys to success in lab sciences such as chemistry, physics, and biology. Biology Labs Online is a series of interactive, inquiry-based biology simulations and exercises designed for college and AP high school biology students. The metric system, or international system (SI), is used to describe measurements of many quantities, such as length, mass, volume, and temperature. Conversation. _____ drops Follow the directions to find the number of drops in 1 milliliter of water, then answer the questions. A cubic centimeter is also called a milliliter (mL) and is 1/1000 of a liter. A researcher may randomly sample on the higher end or lower end of the measurement range, which would decrease precision. In most cases, it is simplest to copy the experiment into a word processing program, and then print it out. Upon completion of this lab you will be able to: Measure length, volume and mass using appropriate scientific instruments; Express measurements using the correct number of significant figures Large hanging weights and precision masses with accuracy to 0.01 gram meet your science lab needs.

To access experiments, click on one of the experiments listed below. In almost every facet of modern life, values – measurements – play an important role. Accurate observations of phenomena are one of the keys to success in lab sciences such as chemistry, physics, and biology. 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). For some experiments, you may need a calculator. In this lab, you will examine the structure of the heart, explore the blood types as well as the RH factor, and measure blood pressure as well as pulse rate. The first purpose was to identify the metric units used to measure length, volume, mass, and temperature. Do not use scientific notation (exponents) or fractions in your answers to the questions below. Magnitude is the actual numerical value of a measurement (e.g., 45 or 0.237). ...
