Experiment: The purpose of this experiment was to test which variables affected the horses sympathetic nervous system leading the horse to stress and drooling. There were multiple variables tested such as the dilation of the horses eyes‚ if the horses ears were up and lastly if the horse drooled. In order to conduct this experiment‚ we had one horse getting honked at by a car and then testing those variables to

compensation for participating in this experiment. These participants were divided into six groups based on where they were sitting. Design The Stroop Test was used in order to test the effect of interference on reaction time. This was done by using three different types of slides‚ each with either 20 words or 20 colored boxes‚ and recording how many words participants could read the color of‚ rather than the word itself. The colors used in this experiment were red‚ green‚ blue‚ purple and brown

Introduction The presence of enzymes in our bodies controls the multiple events happening simultaneously by lowering the activation energy of chemical reactions. (1) These enzymes perform best under a certain set of environmental conditions. The purpose of this laboratory investigation is to examine the activity or horseradish peroxidase‚ an enzyme‚ under a wide range of circumstances and key

9 grams of copper 2.9 grams of iron Masking tape Permanent marker Procedures 1. Fill all six jars with water so that they are nearly full. It may be helpful to use a measuring cup to make sure that each jar has exactly the same amount of water. 2. Attach a vertical strip of masking tape to the side of each of your test tubes (for marking the water level)and using the permanent marker‚ make a mark on the tape about 1 cm down from the mouth of the test tube. This will be the outside water level

Title Experiment with a spiral spring (Oscillation) Objective 1. To show how the time of vertical oscillation depends on the load 2. To determine the spring constant 3. To determine the effective mass of the spring Introduction In this experiment‚ it is to show how the time of vertical oscillation depends on the load‚ to determine the spring constant and to determine the effective mass of the spring. An ideal spring is remarkable in the sense that

Change in Precipitation Ramon Pena BIO101 February 14‚ 2011 Dr. Richard Steiner Change in Precipitation Introduction This experiment will take course during a 300-year-time -period simulation. This experiment will consist of two islands‚ Darwin Island‚ Wallace Island and take only into account the bird population of these two islands. The parameter will stay the same‚ except for one variable; precipitation. I will record how the precipitation changes the beak size of the bird population

Introduction Milgram Experiment Method 40 men were recruited for a lab experiment investigating “learning”. In exchange for their participation‚ each person was paid $4.50. After the WWII‚ Stanley Milgram a psychologist of Yale University posed a question‚ “Could it be that Eichmann and his million accomplices in the Holocaust were just following orders? Could we call them all accomplices? These men were introduced to another participant who were actually actors. These men were given role
