mass of the beans Dependent variable: the different types of beans Control: The beans Purpose: The purpose of the lab is to find equal measurement of each type of bean. After you find the mass of each bean you need to find the relative mass of each bean. The navy bean will have the smallest relative mass. You will need to wear safety goggles and a lab apron and wash hands after the lab is finished. If you drop any beans pick them up immediately to prevent anyone from slipping. Materials Safety goggles

cubes: B.S.12 – Part 2 ASTM : C 109 ¾ Tensile strength of mortar using briquettes: B.S.12 – Part 2 ASTM : C 109 General Discussion: In these tests (Compressive and Tensile tests) we measured the mechanical strength of the hardened cement. These tests are done on cement – sand mortar and not on the hardened cement itself‚ the r eason of not using neat cement past on these test is in th e following two points: 1. Difficulties in molding (Getting good specimens). 2. Large variability

November‚ 2011 Aim: To show that when Hot and Cold water are mixed‚ heat lost by hot water is equal to heat gained by cold water. Theory: This Lab is done to demonstrate “the Law of Conservation of Energy”‚ which implies: - “the heat lost by one (1) substance must be equal to the heat gained by another substance within the system”. Apparatus: Two (2) similar Calorimeters: a Thermometer: a Measuring Cylinder: a Bunsen burner: a Tripod: an Asbestos Gauze Cork Mat. Procedure: * The tripod

Earth’s Energy Budget Introduction: This Albedo lab was created to help explain the process in which the Earth reflects solar energy back to space. The fraction of radiation reflected by an object is known as an albedo. In relation to the atmosphere‚ as solar radiation reaches certain colors on the surface of Earth‚ more radiation is absorbed by darker colors‚ which in turn decreases the solar radiation that reflects back to the atmosphere. If a person was interested in learning more

Physiology‚ Berry HOMEOSTASIS LAB ACTIVITY Introduction: Homeostasis means maintaining a relatively constant state of the body’s internal environment. The term used to describe a pattern of response to restore the body to normal stable level is termed negative feedback. When a stimulus (environment change) is met by a response that reverses (negates) the trend of the stimulus‚ it is negative feedback. As a result the internal environment is returned to normal. Pulse rate is constantly checked

Lab Report Janice Chisholm SCI207: Dependence of Man on the Environment Instructor: Lee Ott April 28‚ 2013 1. What patterns do you observe on the information table 4? While observing the information in table 4‚ it appears that the number of fish changes from time to time and the oxygen increases and / or decreases when this occurs. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water?

The positive charge builds significantly then remains as the charge producer is removed. 3. The negative charge builds significantly then remains as the charge producer is removed. 4. When the white charge producer is lowered then removed from the ice pail with out touching the positive charge builds then drops when the charger is removed. 5. When the ice pail
