The lab performed was laboratory techniques and measurements. The purpose of this lab was to familiarize ourselves with different techniques used in the lab‚ taking proper measurements‚ and how to use the International System of Units (SI). Throughout lab we learned about mas‚ volume‚ length and temperature‚ and to be able determine density and concentration. To be able to documents properly and make effective observations we must be able to understand the International Measurement System. Length

Recognizing Laboratory Safety Purpose: The purpose of this lab is to stay safe no matter what you’re doing in lab. You may be working with dangerous materials such as glass or acid. Procedure: I am following the procedure described in pages 21-24 in the Biology Laboratory Manual. Observations: Does not apply to this lab Answers to Questions: 1. The flask symbol means glassware safety. Glassware can be broken easily. 2. The goggle symbol means that you are working with fire. It is extremely

Title Laboratory Techniques and Measurements Purpose The purpose of this experiment is to determine mass‚ length‚ temperature‚ volume‚ and density of objects and liquids using common measuring devices and algebraic formulas. The metric system‚ the most common set of measurements used in science‚ which includes meters‚ liters‚ Celsius‚ and grams will be used. Procedure The following items were used within the experiment: (1) Metric ruler with centimeter (cm) and millimeter (mm)‚ (1)

Federalism is a laboratory of democracy because states and cities are vital parts of American government. States should cater its laws to the values and wants of the people in the state. With certain situations and instances‚ national laws do not work across the nation. For example‚ laws regarding hunting‚ fishing‚ and mining may be pertinent in Alaska‚ but would be completely impractical and even dangerous if applied to some other states. Federalism allows for each individual state to create laws

Format of a Laboratory Report Your laboratory report should be divided into the following sections. Be sure to label each section! I. Introduction A brief statement of the purpose of the experiment. This is also a good place to show relevant structures and chemical equations. II. Experimental Procedure A brief outline of the experimental procedure. Be particular about reporting the amounts of materials used and any modifications made to the original procedure (avoid simply

Nahom Assefa CHM-201 General Chemistry and Laboratory I Laboratory 8. Spectroscopy Purpose: Spectroscopy is the study of matter interacting with electro-magnetic radiation (e.g. Light). In this lab‚ we will separate some light sources in to constituent colors and find out the wavelength of some atomic emissions. We will also try to compare the line spectra found from gas discharge tubes and flame emissions. Finally‚ we will measure

Biology Laboratory Report Practical 4 Food tests Introduction The main components of food are proteins‚ fats‚ carbohydrates‚ and‚ of course‚ water. Proteins‚ lipids and carbohydrates are carriers about energy necessary for vital activity. They are a plastic material for the formation of structures of the body‚ as well as used for the synthesis of hormones and substances that transmit signals in the nervous system. Our food also includes food (plant) fibers‚ has recently seemed unnecessary ballast

On Friday July 15‚ my group of medical student visited the simulation laboratory. After climbing a couple sets of stairs we were broken off into three different groups for three different sets of activities. The first for me a combination of a couple of simulations. The first one was a simulation designed to help surgeons further develop their skills. We used small clamps to pick up and move rings to different poles. This seems quite simple but we had to do it looking at a monitor that projected

Laboratory Measurements and Density Objectives: A. To determine the density of Aluminum (lit. value = 2.7 g/cm3) by determining its mass‚ and measuring its volume by dimensional analysis and water displacement. We will also examine the % error in our determination based on the literature value. B. To determine the mass and diameter of select ball bearing. Plot graphs of mass vs. diameter‚ mass vs. surface area‚ and mass vs. volume. Afterwards use slop of the mass vs. volume graph to determine density
