Popcorn Experiment Experiment performed on 8/26/11 Biology 101 Introduction: “The oldest popcorn ever found was discovered in the “Bat Cave” of central New Mexico. Archaeologists found 80‚000-year-old corn pollen below Mexico City”. “The popcorn was thougt to be about 5‚600 years old”. (www.factmonster.com/spot/popcorn1.html) This particular pollen is almost identical to today’s popcorn pollen. Researchers came up with the theory that popcorn could have been a Stone Age snack for “cave

SUMMARY The aim is to observe distillation process of ethanol-water solution and to measure the alcohol content after process in this experiment. 500 ml of solution with an alcohol content of 32% (v/v) is used for this experiment. Temperature values are recorded for every 10 ml alcohol obtained in the flask. The process is repeated in our experiment and for the first process‚ the data collection process continues until the distillate reaches to 200 ml. The concentration of alcohol is measured for

EXPERIMENT 3: ISENTROPIC EXPANSION PROCESS Objective In order to demonstrate the isentropic expansion process. Introduction Isentropic means no change in entropy. Entropy is a thermodynamic property that is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. In simple terms‚ the measure of the level of disorder in a closed but changing system‚ a system in which energy can only be transferred in one direction from an ordered state to a disordered

A Group Discussion at a B-School can be defined as a formal discussion involving 10 to 12 participants in a group. They are given a topic. After some time‚ during which they collect their thoughts‚ the group is asked to discuss the topic for 20 to 25 minutes. B-Schools use the Group Discussion process to assess a candidate’s personality traits. Here are some of the most important personality traits that a candidate should possess to do well at a Group Discussion: 1. Team Player B-Schools

Intercontinental University Aspects of Psychology Individual Project # 2 Experiments and Adaption July 30‚ 2012 ABSTRACT This paper is explaining five experiments; the process and results. It talks about sensory adaptation and how adaptation is evident in each of the experimental results. It also provides a comprehensive description of the sensory systems in the experiments that I performed. Before starting the four experiments‚ I had to remember that I had to keep in mind that there are five

Adsorption Experiment This paper will be discussion the adsorption experiment conducted in Dr.O lab class. This paper will cover what Chitin/Chitson are but before explaining what these are it is best to get an understanding of what adsorption‚ absorption and sorption are. Adsorption is the accumulation of gases‚ liquids‚ or solutes on the surface of a solid or liquid. This binding is very weak. Almost anything such as fluids that dissolves can break the binding of the molecules. In addition adsorption

Experiments: Doctors‚ Experiments‚ and Results Melissa Anjeanette Edwards POLYTECH High School of Kent County‚ Woodside‚ Delaware Abstract During World War II experiments were done on the prisoners of war in Nazi Germany. Doctors for these camps came in all shapes and sizes including former S.S. Troops‚ Women‚ and a variety of prisoner doctors. The experiments differed as much as the doctors themselves; however they stayed the same in one factor‚ medical curiosity become killing in atrocious

pleasant‚ fruit-like odors and are the chemicals responsible for the odors and flavors of many fruits (oranges‚ bananas‚ pineapples) and flowers. In most cases‚ such natural products get their properties from a mixture of organic compounds. In this experiment you will prepare two esters of o-hydroxybenzoic acid‚ more commonly known as salicylic acid. One of the esters‚ acetylsalicylic acid‚ is aspirin‚ the common analgesic. We will synthesize aspirin by mixing salicylic acid with acetic anhydride. The

Throughout the experiments the size of the balloons stayed about the same size except for in experiment 3. Also the bottles that had more sugar had a stronger scent of alcohol and also contained more foam on top of the liquid. All yeast in each of the bottles seemed to have fermented at the same time and stopped/slowed down‚ the growing process‚ at the same time. Bottle 3 also would always overflow and the foam would fill the ballon in every experiment. Another trend with bottle 3 was that in the
