determined using a dial caliper and the mass‚ a triple beam balance. The results of the error for diameter were not as expected while the results of the volume and density were deviated greatly from expectations; only the weight had a small error. Experimental Instruments: 1. Steel ball 2. Dial caliper (Mano Stat Corp.) 3. Triple beam balance (OHAUS) Procedure: 1. The steel ball was measured for its diameter using the caliper using gloves to not add hand oil to the ball. 2. The ball was

as an exposure to fertilizer. By changing the independent variable (whether or not the plant was planted with fertilizer)‚ you are testing to see how the dependent variable would change (the growth of plants). In order to assure that there is no experimental error‚ a control must be kept to produce the most accurate data on what effect fertilizer has on plant growth. Although many environmental factors could be tested‚ such as the amount of sunlight exposed to or the amount of water given‚ some of

Research Question Investigate the effect of temperature on the rate of respiration of various parts of plants (germinating seeds and dormant (non-germinating) seeds)‚ by measuring the oxygen consumption and change in gas volume of respirometers containing either germinating or non-germinating seeds at different temperatures to measure the rate of respiration of these beans at different temperatures. Hypothesis 1.Germinating seeds have a higher rate of respiration as compared to non-germinating

Experimental Design Bio 1110 ! ! Background: Plants need water to survive. Water makes up 80-95% of the mass in plant tissues. Transpiration is the loss of water from plants in vapor form. 95% of the water is absorbed from the soil for transpiration and 5% is absorbed during photosynthesis for producing necessary carbohydrates for growth. The rate of transpiration is dependent on the amount of water in which is available within the plant‚ soil‚ and on sufficient energy to vaporize water

Chemical Equilibrium ------------------------------------------------- ------------------------------------------------- RESULTS AND DISCUSSION A. Iron-Silver Equilibrium In studying equilibrium between iron and silver‚ 0.10 M FeSO4 and 0.10 M AgNO3 were used. The balanced equation for the reaction is: FeSO4 (aq) + 2 AgNO3 (aq) ↔ Fe(NO3)2 (aq) + Ag2SO4 (s) It has a net equation of: Fe2+(aq) + Ag+(aq) ↔ Fe3+(aq) + Ag(s) This part of the experiment

AND CULTURAL ANALYSIS AS EXPERIMENTAL SYSTEMS In this weeks reading by Michael M.J. Fischer provides a spectrum of definitions of what culture embodies. Fischer also supplies a vast amount of examples that relate to various classifications of cultures. He describes “cultures as a methodological concept or tool of inquiry‚ might best be understood in terms of its historically layered growth of specifications and differentiations‚ refined into a series of “experimental systems” that‚ in a manner

the 1960’s‚ and has been described as the reluctance of a person to help another in distress or report an emergency when in the presence of other bystanders. The bystander effect was initially observed in adults (Darley & Latané‚ 1968)‚ who found themselves either alone or in a group in a waiting room when they noticed the room began to fill with smoke. It was found that by the 6-minute mark 75% of people who were alone reported the smoke; however‚ when people were in groups in the waiting room only
