hear the horn. Experimental Subject- This horse does hear the horn. B.) The Scientific Method: Observation: Horses drool. Question: Why do horses drool? Hypothesis: The sound of the car horn will induce the sympathetic nervous system of the horse therefore causing distress and anxiety within the horse which will then lead the horse to stop drooling (McKinley‚ 2016). C.) Experiment: The purpose of this experiment was to test which variables affected the horses sympathetic nervous system leading the

What Is Portfolio? Although portfolios are used in the assessment of student’s performance in nowadays‚ they are used as a method by architects‚ painters‚ photographers and artists in showing their works. However‚ as portfolio has been used for different purposes it maybe different from than that of artists. It is not possible to use only one definition for portfolio. Definition of portfolio may change according to users’ purpose and way of usage. Many researchers defined portfolio in order

Crater Design Experiment Aim: To see how the height in which the ball is dropped from affects the depth of the crater. Hypothesis: I predict that as the height in which the ball is dropped from increases‚ so does the depth of the crater (the data will be directly proportional). The scientific knowledge which supports this is that the golf ball has a gravitational potential energy which increases as the ball is dropped from higher heights. When the height increases the ball gains more gravitational

The methods used to gather the data has consisted of primary research‚ Questionnaires were created which held 20 questions‚ around 149 questionnaires were handed out to the public of ages 16-25. A range of open and closed questions where used within the questionnaire to gain qualitative and quantitative information from the users. The open questions provide a deeper understanding of what the user wants and how they want it; this is more relevant to the interviews which have been done on different

Success of Dugesia tigrina regeneration in different water temperatures Abstract: The experiment at hand aimed to determine if the species Duguesia tigrina has an optimal temperature for regeneration. The experiment used three different spring water treatments of different temperatures. The treatments included a cool 12° treatment‚ a room temperature 25° treatment‚ and a warm 30° treatment. Each of the D. tigrina were cut in half‚ and each half was placed into a designated section of a water treatment

Environmental Variables and their effect on Horseradish Peroxidase Abstract There are several factors that can affect the rate of reaction of peroxidase such as temperature‚ pH‚ concentration of peroxidase present and whether or not it has been boiled. Our experimental data demonstrated that peroxidase activity peaked between 23 degrees Celsius and 32 degrees Celsius. We found the pH to be 7 for optimal activity. As far as the concentration is concerned our results showed that as the concentration

On April 5 1968 Jane Elliot preformed the famous experiment in her classroom separating blue-eyed and brown-eyed students. She had separated them by making one eye group inferior to the other making them have certain benefits and better treatment than the other. Then it was
