Introduction: The purpose of the plant growth experiment was to test the affect of plant fertilizer during plant growth. The system we were working with allowed us to test the recommended amount and double the recommended amount of Miracle Grow in comparison to a control of an all natural growing plant. The plants we were testing were radishes We decided on testing the validity of Miracle Grow with radishes to determine if fertilizers are worth purchasing. Hypothesis: If the recommended amount

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

Many people drink sugary drinks every day‚ but really how bad is it for your teeth? This project shows the repercussions of drinking sugary soft drinks. This experiment tests eight adult teeth in eight different soft drinks for 48 hours. The results are equivalent to not brushing your teeth for two days or constantly sipping on a soft drink for more than an hour. If the sugar and acid particles are left on the teeth‚ then more acid is made by the sugar and the enamel starts to wear away. This can

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

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

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

Commercializing the Kunst 1600 Dry Piston Vacuum Pump Q1. List the major quantifiable value and price elements associated with the Kunst 1600. Answer: With its enhanced features‚ the Kunst 1600 is able to pump just as efficiently as a traditional 6 CFM pump in the same amount of time‚ but because it is a compressor‚ it can run longer and cooler than any conventional pump and requires no oil changes! Savings on oil changes‚ cleanup costs‚ and disposal fees alone can equal almost $1‚300* per
