SUMMARY The aim is to observe distillation process of ethanol-water solution and to measure the alcohol content after process in this experiment. 500 ml of solution with an alcohol content of 32% (v/v) is used for this experiment. Temperature values are recorded for every 10 ml alcohol obtained in the flask. The process is repeated in our experiment and for the first process‚ the data collection process continues until the distillate reaches to 200 ml. The concentration of alcohol is measured for

Is it normally acceptable to experiment on non-human animals to develop products and medicines that benefit human beings? New scientific research has cast grave doubt on the safety testing of hundreds of thousands of consumer products. Everyday products‚ from soft drinks to paints‚ contain numerous synthetic chemicals. Official assurances of the safety of these chemicals are based largely on animal experiments. But recent results from a consortium in America suggested such assurances may be worthless

Purpose: To find the initial velocity of a marble leaving a ramp using time‚ range‚ and background information learned in class. Equipment: The equipment used in this experiment was a toy track and ramp‚ a small marble‚ multiple Physics textbooks‚ meter sticks‚ bright-colored cardstock‚ masking tape‚ sidewalk chalk‚ plastic bag and a cloth. Procedure: Our experimental values include the height that the marble would travel‚ y= 88.1 cm‚ and our ramp angle‚ θ= 44.0°. These independent variables

Brenda Richardson Intro. to Psych. Chapter 6 Part 2 Loftus Experiment Elizabeth Loftus‚ a psychologist and expert on memory‚ has conducted much research on human memories‚ real and imagined‚ and how that may happen. Loftus‚ personally‚ has experienced the misinformation effect and eyewitness memory. Even though there are several experiments outlined‚ I chose the ’Lost in the Mall’ experiment as more fitting to the sex abuse testimony she gave. Participants‚ twenty-four of them‚

Section November 7‚ 2012 Abstract The effect of water and fertilizer on corn seedlings was examined. It was hypothesized before the experiment that enough water with sunlight and air should make the plants grow healthy. It has to do with photosynthesis. Fertilizer is also going to make the plants grow much faster; this is because of the nutrients in it. The experiment took about four to six weeks to complete; it took some days for the seed to germinate before planting. The corn was growing there were
