Key Terms In a lab experiment there has to be a detailed written page. On the written page you should include purpose, hypothesis, materials, procedure, observations, conclusion, application, and finally a diagram. Purpose is used to describe why the experiment has to be done. Hypothesis is used before the experiment has started; it is an educated guess or can be said as a prediction. Materials are one of the 4 most important pieces in a lab. Without the materials you don’t know what tools

University of Phoenix Material Week 1 Exercises Prepare written answers to the following exercises: 1. As a field agent, you must determine the cause of a disease outbreak in the Los Angeles, California, area. You discover that the disease originates from contaminated halibut. You write a report to your supervisor, which includes a description of the physical dimensions of the fish (length and weight). Your supervisor asks that you send the fish and a report about the fish

Physiological Needs these are biological needs. They consist of needs for oxygen, food, water, and a relatively constant body temperature. They are the strongest needs because if a person were deprived of all needs, the physiological ones would come first in the person's search for satisfaction. Safety Needs when all physiological needs are satisfied and are no longer controlling thoughts and behaviors, the needs for security can become active. Adults have little awareness of their security

MASLOW HIERARCHY Maslow Hierarchy University of Phoenix PSY/ 211 Christina Hawkey In Maslow's Hierarchy of needs several things are brought to the surface for example, there is a pyramid of information. In which Maslow separates from bottom being the least and most obtainable, all the way to the top being the most important. At the bottom it begins with physiological needs like, breathing, food, water,

HEAT TRANSFER IN VAROIUS MATERIALS. To find the best insulator of heat from various materials. Insulators are materials that impede the free flow of electrons from atom to atom and molecule to molecule, they generally restricts movement only around the atom they are attached to. They can move from one side of the atom to the other but are unable to leave the atom. Conductors are materials that permit electrons to flow freely from particle to particle. An object made of a

Discussion: This lab experiment consisted in locating the metacentric point in order to test the buoyancy stability of a lab pontoon under certain circumstances. The metacenter is the point of intersection of the buoyant force and the center of gravity. In order to verify the stability conditions of an immersed body is necessary to locate its metacentric point. One of the conditions is that when the center of buoyancy and center of gravity are coincident, the body is stable. In this experiment

Today people seem to be obsessed with their diets. Food is a high priority item on the lifestyle agenda with a marked focus on healthy eating. "You are what you eat," says Ayurveda, the ancient Indian science of life. Food is a basic human need. We always need to know what we eat because food affects practically all aspects of our life. Nowadays, in the manufacturing age, our society still faces the food problem. This is a problem of quality, not volume. Our producing system is capable of producing
