variable The variable is the important aspects of the research. In research the concept are measure from variable. Variable are anythings that can take on differing or varing values. it mean that the value of variable vary from person to person‚ time to time or place to place but the meaning of variable are same to all. Thus variable are the charactestics of person‚ groups‚ objects‚ ideas‚ feeling or other thing that researcher want to measure. Variables are thus anything that can take on differing

My final device was simple‚ yet effective. It consisted of a straw pyramid in a bag of popcorn. Two of the main restrictions for this project were mass and size. The bag that i put my materials in was within the size limit. The mass of popcorn and straws is very little. Popcorn can also absorb a lot of shock‚ stress‚ and kinetic energy. Straws absorb energy as well. So I decided to use those two materials. First‚ I put the egg directly into a pyramid of straws. Putting the egg in the pyramid instead

512-513). Then there were the racial problems that still plagued the non-segregated North as whites reacted to blacks becoming an increasing part of their community. Wilkerson tells of incidents like the story of the Clark family who were run out of their new apartment in an all-white neighborhood of Chicago for being black and the ensuing race riot (372-376). Knowing that even with these losses and the harsh conditions of the North that their lives were still better than when they were in the South‚ allows

measure the rate of respiration in yeast and find out what factors affect the rate of respiration. I am going to change the concentration of the glucose solution and I’m going to measure the volume of gas produced during respiration in cm³. Yeast contains enzymes. Enzymes speed up a chemical reaction – they’re biological catalysts. Yeast can respire both aerobically and anaerobic; the anaerobic respiration of yeast is known as fermentation. The equation for this type of respiration in yeast is:

are organisms that have a limited ability to control their body temperature. Their cellular activities generate little heat. Their body temperatures rise and fall with ambient temperature changes. Most organisms are ectotherms. Examples are plants‚ all invertebrates‚ fish‚ amphibians and reptiles - ENDOTHERMS are organisms whose metabolism generates enough heat to maintain an internal temperature independent of the ambient temperature. Examples are birds and mammals - EXTENSION (Not really needed

An experiment to investigate the Stroop effect in which participants are asked to name the colour in which a word is written‚ that word having either a colour- association or a neutral association. ABSTRACT. This study was an investigation of the cognitive processes at work during a variation of the classic Stroop test and effect‚ in which the degree of intrusion into automatic thought processes may be witnessed in a colour identification task. It was found that the rate of word identification

conducted to determine the optimal temperature for bacterial and fungal Amylases and evaluate how temperature affects the catabolic rate of enzymes. Enzyme reaction rate was measured using an Iodine test in which drops of starch solution with either fungal or bacterial Amylase exposed to different temperatures were mixed with Iodine. Iodine is a dark blue color in the presence of starch and turns light yellow in its absence. Bacterial Amylase had an optimal temperature of 55°C‚ meaning that starch was

Discussion The purpose of this experiment was to determine if splitting a bean would affect its rate of respiration. Splitting a bean does not impact its rate of respiration. This is shown in the data‚ while the average rate of respiration for Whole beans is 1.35 and the rate of respiration for 1.16‚ the standard error of the mean is .15. Because the standard error of the mean is so high‚ they overlap in both of the data sets‚ which shows that the data is very similar. This is better shown in the
