Performance (page32) 1. In this experiment‚ what might be some extraneous variables affecting the students’ test performance? 2. What might educators do to try to prevent the effect of the “dumb jock” negative stereotype on college athletes? The experiment done by Jameson‚ Diehl‚ and Danso‚ attests that a negative stereotype‚ being referred to as a “dumb jock”‚ may have negative impacts on the test performance of athletes. There were two groups in their experiment. The experimental group was exposed

Discussion: First of all‚ rinse all the apparatus that being used in the experiment with hydrochloric acid (HCL) then followed with distilled water (H₂O). Then‚ prepared the saturated calcium hydroxide (Ca (OH) ₂) solution into a filter funnel and filter paper over a second conical flask. Pour 100.00mL of saturated Ca (OH)₂ solution into a beaker and pour the solution through the filter paper by flowing the solution through a glass rod. After that‚ use a thermometer to measure the temperature of

Abstract The experiment aims to observe if simpler substrates makes the rate of cellular respiration faster. Using yeast‚ smith fermentation tubes and different substrates namely‚ starch‚ lactose‚ sucrose‚ glucose and fructose‚ which are from different kinds of carbohydrates‚ ranging from the simplest sugars glucose and fructose to the polysaccharide starch and water as the control‚ the hypothesis was tested. With the span of thirty minutes with five-minute intervals‚ the height of carbon dioxide

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

Purpose The reason for this experiment is to prove that objects of different masses‚ when dropped from the same height‚ fall at the same velocity. Apparatus - 2 Marbles of different mass‚ one steel and one nylon - Dropping Mechanism with a lever to hold the marble and pull for drop - Bee Spi (measures velocity in kilometers per hour.) - Box to catch the marble on the way down Procedure The dropping mechanism was set up‚ with the BeeSpi attached to it at 26.5” from the lever that drops

When performing this experiment make sure all materials are present this includes: Blood Pressure Probe‚ a Sphygmomanometer‚ computer with Logger Pro software‚ Stethoscope‚ Logger Pro cables‚ and a timer if you so chose. Using the Blood Pressure Probes‚ Logger Pro cable‚ and the software you are ready to begin the experiment. Have a scary video pulled up from youtube that is within the time limit of 0-120 seconds. It would be wise to have the video around 60 seconds because that is the time frame

Experiment #10 & #11 The Synthesis of Cobalt Oxalate Hydrate The Synthesis of a Nitrite Complex February 5‚ 2012 Chemistry 1211L - 146 - Spring 2012 Procedure The Synthesis of Cobalt Oxalate Hydrate Place 100 ml of distilled water in a 250-ml (or 400-ml) beaker. Add 1.26g of oxalic acid dihydrate (H2C2O4.2H2O) and 1 ml of concentrated ammonia. Stir the mixture until the solid has dissolved completely. Dissolve 2.34 g of cobalt chloride hexahydrate (CoCl2.6H2O) in 100 ml of water

In my experiment of breaking the norm‚ I did two different things. in one of my “experiments” I would hold doors anywhere I where for the people that were behind me and wait for a response‚ when the person was educated enough to say thank you I would smile and let it go. When the opposite happened‚ whenever the person behind me did not say thank you I would compliment myself. I would thank myself for holding the door instead. The first time I conducted this specific experiment I was at

minutes of aerobic exercise. Each suggestive treatment is complete with a reasonable physiological rationale. I have come up with an experiment to test the 3 variables to figure out what treatments if any will work the best. My hypothesis is that all 3 of the suggestive treatments when done before flying on an airplane‚ will reduce the effects of jet lag. Experiment: A commercial airplane traveling from New York City to Los Angles non –stop will be selected at random. All passengers will be randomly

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
