Biology College of Science De La Salle University – Dasmariñas Dasmariñas‚ Cavite Philippines ABSTRACT This experiment was performed to learn the technique of acid-base titration and to compare the efficiency of commercially available antacids by looking at their weight of HCl and weight of antacid values. The analysis of antacid tablets was highlighted in this experiment. The efficiency of antacid tablets was determined and compared when the number of grams of HCl can be neutralized by

Are you looking for a fun experiment that you can perform for a psychology class? This experiment on gender and memory is relatively quick and easy to perform‚ which is a bonus if you are short on time and resources. Could gender differences play a role in short-term memory? We often hear women complain that their husbands can’t remember important dates like anniversaries or birthdays‚ but could this phenomenon be due to something like memory differences between men and women. Some previous research

community as a whole is altered (Friedman 2017). To study succession‚ one must use one of the following methods: to observe any patterns that occur‚ to conduct experiments that manipulate specific variables in a community‚ or to construct a model that may undergo succession. One example of an experiment that measures microbial succession was an experiment observing changes in traditional Chinese soy sauce over time (Sulaiman et al. 2014). The fermentation of the soy sauce brine revealed that the primary bacteria

Under this is the Dermis‚ this is a layer of connective tissue which provides the skins elasticity and strength‚ it also contains sensory nerve endings‚ blood and lymph vessels‚ sebaceous and sweat glands. Under this layer is the Subcutaneous fat layer‚ this layer separates the skin from the underlying bone and muscle with a rich blood supply it also serves as an insulator and energy store.

Abstract Over a two week period of time in the laboratory‚ we experimented and tested the reaction rate of a peroxidase enzyme and the factors that affected it‚ both positively and negatively. The purpose of these experiments was to probe and manipulate the activity of the enzyme peroxidase by varying temperature‚ pH‚ the amount of enzyme compared to the substrate and the effect of hydroxylamine. Peroxidase activity is expressed when the potato extract is subjected to stresses such as low temperature

between the pressure and temperature of saturated steam in equilibrium with water. 2. To determine the vapour pressure curve. Introduction Properties of a fluid can change when heat and work are applied to it. There’s an interchange between the fluid and its surroundings when heat and work are applied according to the study of thermodynamics. Substances such as gases and vapors are often referred as P-V-T substances. Theory: An ideal gas obeys the equation of state that the pressure‚ specific

A. Stanford Prison Experiment- In this experiment‚ students volunteered to be a part of a psychology experiment that was being conducted at Stanford College. Because of the situation around them‚ they conformed to the environment‚ even though it was only a simple experiment in a Stanford hallway. Embarrassed and yet impressed‚ the experimenters stated this‚ “The negative‚ anti-social reactions observed were not the product of an environment created by combining a collection of deviant personalities

The Asch Experiment How conformity influenced the world Megan Foster Many psychologists have performed experiments to prove theories and replicate actions. One of these most famous psychologists is Solomon Asch. In 1955‚ social psychologist Asch designed and experiment to show the effects of conformity in today’s society. Conformity is the adjusting of one’s behavior or thinking to coincide with group standard or belief. The results from the experiment were shocking and changed the way social
