For this experiment‚ there were four onion bulbs labeled A‚ B‚ C‚ and D. Bulbs B‚ C‚ and D were each immersed in a different concentration of coffee. Bulb A acted as the control because it was not immersed in any concentration of coffee; instead‚ the onion roots grew in water. The following is a list‚ in order‚ of the concentration of caffeine bulbs B‚ C‚ and D were in: 0.1%‚ 0.3%‚ and 0.5%. Four test tubes were gathered to set up the experiment‚ each holding an onion bulb. After each day‚ every

Kevin Doherty Experimenting with Plant Growth Team Rocket Science Introduction: The purpose of the experiment was to establish whether the concentration of Schultz fertilizer that was added to the radish seeds effects the speed of growth during the six-week time frame of the study. The major variables with this study are proficient communications among the team‚ the seeds‚ soil‚ water concentration‚ fertilizer‚ light exposure‚ temperature of the room‚ consistency of following watering (watering

Silver Mirror Experiment Background: This experiment was first conducted by Bernhard Tollens‚ it is used to determine whether a carbonyl containing compound is an aldehyde or a ketone. An aldehyde is a compound containing a formyl group (CHO).The experiment involves diamminesilver complex and a chemical reagent (also known as “Tollens’ reagent”) which in this case is glucose. In a successful experiment a reflective silver metal should precipitate‚ with characteristics identical to that of a mirror’

In the eye opening documentary‚ The Human Experiment‚ directed by Don Hardy and Dana Nachman‚ the many health dangers of thousands of harmful chemicals in everyday products are exposed. The film explores the lives of people who have been affected by the ubiquitous chemicals found in our food and our homes. The film addresses the battle against powerful industries that are determined to keep consumers in the dark about the dangers of many of their products. The fight against dangerously lethal chemicals

DOE - Design of Experiment DOE is an approach used to identify factors/steps that are contributing most to an observed variation in product specifications. The classical DOE focuses on identifying the factors that affect the level of a product/process response‚ examining the response and forming the mathematical prediction model. The modern DOE‚ introduced by Genichi Taguchi in early 1980s‚ applies in both product and process development to identify the factors that affect the variability of the

Research project #2 Test Tube Meat Scientists have recently traveled to the Netherlands to check out different laboratories researching test tube meat. This is a recent study and may seem far-fetched but we could be eating this meat in the next couple of years. With a new study like this there will be many controversial Pros and Cons. The two articles I researched online were; Burgers From A Lab: The World Of In Vitro Meat and the other is from Beefmagazine.com: Test Tube Meat. Both of the articles

the pulse-echo experiment and the measured air temperature. Hypothesis: I believe the measured air temperature will affect the speed of sound because sound waves are longitudinal waves composed of the alternating compressions and rarefactions in air. If the air temperature is below 0°C‚ then the speed of sound would be lower than 331.6 m/s and if the air temperature is above 0°C‚ then the speed of sound would be higher than 331.6 m/s. Materials: Thermometer‚ closed cardboard tube‚ microphone‚ Data

After a holding period of 18 hours for winter captured crabs and a period of 30 hours for summer captured crabs‚ all individuals were transferred to containers with experimental temperature and salinity levels to begin the experiment. To observe changes due to salinity concentrations over the 48-hour period‚ groups of crabs were exposed to one of the eight salinity treatments‚ and temperature treatments were held constant at 5°C or 15°C to resemble winter or summer field conditions
