During World War II‚ a number of German physicians conducted painful and often deadly experiments on thousands of concentration camp prisoners without their consent. Doctors are looked at as the saviors of mankind‚ the healers‚ and caretakers of our utter existence. Even dating back to ancient civilizations‚ as they revered to doctors as having “special power” to protect life. The practice of medicine by the Nazi doctors is both outrageous and shocking‚ violating the trust placed upon them by humanity

Cartesian Diver Essay The Cartesian Diver is named after the French scientist Rene Descartes. This experiment is supposed to show buoyancy‚ density and different forms of matter at work‚ when demonstrated. To create the Cartesian Diver‚ you’ll simply need: • A empty plastic bottle • A plastic eye dropper • Water 1. Fill the bottle with water‚ but be cautious of spills. 2. Very carefully‚ drop the dropper inside the bottle. Then‚ seal the cap on very tightly. 3. Squeeze the bottle‚ but not too

According to a new study from Harvard University‚ American students tend to drop out before receiving their degree at higher rates than in other developed countries. Only 56 percent of the students who enter America’s colleges and universities graduate within six years‚ while only 29 percent of students who enter two-year programs complete their degrees within three years‚ the study found. Young people in the United States after their High school year seem to not digesting College very well‚ and

The aim of the experiment was to examine the effects that having a rich lipid diet had on the CHO and fat metabolism during the prolonged exercise. The data shows that at rest the body was in a heavy fat metabolism and when exercise started there was a shift of metabolism from fat to CHO. After thirty minutes‚ the metabolism shifted back to a primary metabolism of fat. Examining the data from this experiment to other studies showed a similar result.

1. Dancing Raisins Here’s another quick and easy science experiment. All you need is a glass of clear soda‚ such as ginger ale or club soda‚ and several small raisins. Fill a glass with soda. Leave about ½ inch (12.5 mm) of space at the top. Drop the raisins in. Those tiny bubbles attaching themselves to the raisins are carbon dioxide (CO2) bubbles. The irregular surface of the raisins enables a lot of CO2 to accumulate. When enough gas bubbles attach to the raisins‚ they act like tiny balloons

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’
