Then‚ work with a partner to answer the following questions. 1. What are the variables in this experiment? Identify the manipulated and responding variables and two controlled variables. The manipulated variable is light intensity. The responding variable is pH. Controlled variables include the initial pH‚ the size of the plant sprigs‚ and time

Calorimetry Experiment Purpose: The objective of this lab is to determine the enthalpy change for NaOH(aq) + HCl(aq) NaCl (aq) + H2O(l) Procedure: Before measuring the enthalpy of acid base neutralization‚ my partner Brian and I determined a calorimeter constant‚ using a homemade polystyrene calorimeter. With the following formula and data: qhot= cm (Tf-Ti) qcold=cm(Tf-Ti) SYSTEM DATA SURROUNDINGS DATA Water cold Mass: 50mL Water hot Mass: 50mL C=4.18 C=4.18 Ti=20 C Ti=31

The effect of alcohol concentration on the cell membrane Abstract: In this experiment I found out that as the concentration of the alcohol was increased so did the colour intensity of the solution. This is because the higher concentration of ethanol‚ results in more damage done to the cell membrane‚ resulting in leakage of red pigment from the cell. If the membrane is damaged more‚ more red pigment will leak out of the membrane and into the ethanol. Hypothesis: The higher the concentration

EXPERIMENT 201: WORK‚ ENERGY AND POWER John Michael A. Ramos‚ Phy11l/A5 Abstract The essential conditions to be satisfied for work to be done are: Some force must act on the object. The point of application of force must move in the direction of force. W = F x s. SI unit of work is joule. Energy is the capacity to do work. The two types of mechanical energy are kinetic energy and potential energy. Kinetic energy is the energy possessed by an object by virtue of its motion. Potential energy is

of the consequences of excessive drinking. After connecting with her‚ I wanted to know if alcohol concentration in spirits would affect the cells in the body. Thus‚ I decided to test my theory by adapting a class beetroot experiment to my investigation. The aim of this experiment is to investigate the effect of alcohol concentration on a biotic cell membrane. The human body cannot live long with damaged cells because they are the building blocks of life. Cell membranes are phospholipid bilayers meaning

The Stanford Experiment of the 1970’s was a test of human nature conducted by the Stanford Psychology Department. A total of 24 students with no criminal or physiological health background were selected to be either guards or prisoners. The experiment was planned to last two weeks‚ but after only six days it had to be stopped for it was becoming too much to handle for everyone involved. The guards had disobeyed their instructions and began to physically abuse the prisoners‚ while the prisoners began

commander. However this norm is not always acceptable‚ especially when the followers blindly obey the authority. Throughout this paper I will explore why people are so willing to accept orders particularly in dire situations and how this psychological phenomenon can be addressed in the modern day. Although many of us would agree not to commit crimes‚ Milgram’s experiment proves that humans are easily manipulated. At the beginning of the 1930’s‚ Adolf Hitler’s Nazi Party exploited the widespread discontent
