Parachute Experiment Aim: To investigate the effect of surface area on a performance (more the amount of a parachute better the performance) of a parachute. Hypothesis- More the amount of holes in a parachute‚ faster the rate of the fall. Variables: Dependent variable- The time it takes for the parachute to reach the ground. Control variables:Mass > Adding or subtracting mass from the load. > Clay can be molded around the load to increase mass. > Parts of the load can be cut off to decrease the

The separation scheme was created by centrifuging a controlled sample of one of the ions or anions combined with one of the reagents such as NaCl. It was found that it could be separated out after centrifuging and would result in a sample without the ions or anions if it precipitated. With the data from week one a method of adding the reagents in a certain order would result in the ability to separate all ions or anions out of a solution. Overall‚ knowing how the cations or anions reacted with certain

Tuskegee Syphilis experiment is the most infamous clinical study conducted in the United States between 1932 -1972. The study of natural progression of untreated syphilis in rural Africa American men‚ led to a forty year study which was controversial for reasons related to ethical standards; researchers knowingly failed to treat patients after the 1940s validation of penicillin. The patients with syphilis were never told they had it‚ were part of a case study‚ could leave the experiment at any given

Experiment 7 General Safety Considerations 1. 1-Butanol and 1-bromobutane are toxic and irritating. Avoid all contact by constantly wearing goggles‚ gloves and working in the hood. Neither of these compounds can be poured down the drain. Like all products‚ 1-bromobutane should be turned in to your TA in a labeled vial. Any excess butanol should be discarded in non-halogenated waste. 2. H2SO4 is extremely corrosive. In very diluted form it can be poured down the drain‚ all other precautions

Separation of Iron‚ Salt and Sand Separating a mixture is an example of a physical change. There are several ways to separate a mixture. The use of one’s hands in pulling the parts of a mixture apart is one example. Filtration is another way to separate mixtures. Filtration is the separation of a heterogeneous (not alike‚ different) mixtures‚ by adding a solvent and passing the resulting mixture through a fine mesh or filter. Evaporation of a homogeneous (alike‚ same) mixture will reveal
