Stroop Effect Essay

The ‘Strop Effect’ suggested that the word meanings were extracted when the participants were not attempting to process it. The original ‘Strop Effect’ was illustrated using color. Flowers et al. Developed another version of the ‘Strop Effect’ in 1979. Instead of using color the new version was illustrated using numbers. The task was to say…

Phenolphthalein Lab

The breasted-Lowry theory defines an acid as a hydrogen-ion donor, which basically means the element would donate an ion. Unlike a bas is a hydrogen-ion acceptor which takes on an ion. I learned ammonium is very soluble in water and accepts a hydrogen ion, so it would be a breasted-Lowry base whereas water is a…

Cellular Respiration Lab Report

The complete breakdown of glucose to carbon dioxide and water requires two major steps: 1) glycoside and 2) aerobic respiration. Glycoside produces two TAP. Thirty-four more TAP are produced by aerobic pathways if oxygen is present. In eukaryote, glycoside occurs in the costly. The remaining processes take place in mitochondria. Mitochondria are membrane-enclosed organelles distributed…

Density Lab Report

The density of water is 1, so in order to keep the film container from inking, the density of the sand-filled film container must be less than 1. The equation for density is D=m/V, where m is mass and v is volume. To find the volume of the film container, use the equation V=3. Array,…

Yeast Respiration Lab

The experiments tested yeast respiration in both, warm water at 42 degrees Celsius and at room temperature. The outcome of the experiment indicates the warm water is optimal for yeast respiration in comparison to cold water. Introduction Respiration is the process that converts sugar known as glucose to energy, in this case TAP (Adenosine Troposphere)….

Sieve Analysis Lab Report

The objective of this experiment is to obtain the grading curve for both fine and coarse aggregate. 1. Balance – balance or scale used in testing fine and coarse aggregates shall have readability and accuracy as follows: For fine aggregate, readable to 0. 1 g and accurate to 0. 1 g or 0. 1 %…

Biosphere Lab

The purpose of building this was to measure survivability and to obtain useful research that could be helpful in furthering ecological understanding. There were two missions in which “Biospheres” were sealed inside to accomplish these goals. However, after the second mission it became a place solely for scientific research, not about human survival. For our…

Distillation Lab Report

The purpose of this experiment is to observe what happens when two liquids with a boiling point of 79 and 100 degrees centigrade are heated together and allowed to boil over a specific period, to use the density to determine regenerate composition of ethanol and water and also to understand the process to separating a…

Egg Lab Report

The purpose of this experiment is to show the effects of osmosis on the De-shelled egg. I hypothesize that the egg will increase in size in the vinegar and shrink in the syrup, staying relatively the same size in the water. Methods: Fresh boiled and shelled eggs is used in this experiment. The eggs were…

Rat Dissection Lab Report

The Public Meeting and Watchtower Study are often led on Sundays. The first is a 30-minute Bible-based lecture that is designed to be of interest both to members of the congregation and to visitors. The context of the bible based lecture was talking to your children about sex, the speakers started to explain how talking…

Metabolism Lab Report

The purpose of this lab was to see how the changes in exercise intensity affect the rate of metabolism within the body. Methods: In this lab, indirect calorimeter was used to measure metabolic rate by calculating caloric expenditure by the measurements of oxygen consumption. The variables measured were the fraction of oxygen expired, the fraction…

Planarians have become a vital model system for…

Human Traits Lab

There are two types of genes, the dominant and the recessive genes. The dominants, often represented by a capital letter, are that when present, the living thing will have the characteristic. Recessive genes, represented by a lower case letter can be together with a dominant gene or another recessive gene. For example: suppose that in…

Seed Labs

There are steps that vary in germination, what first happens is the seed’s radical comes out and then the roots also come out. The next step is the embryonic shoot that includes the seed leaves. The rate of germination depends on the species of plant being grown and its environmental factors. In the experiment, students…
