Lab Experiment Coin Lab - 950 Words

Coin lab My group decided to look at how yeast would be transmitted by passing the coin without washing our hands. We also decided to look at how the yeast would be transmitted if a member of our group touched the coin and then a different member touched the fingertip of the person who touched the coin. Our final experiment was to see how the yeast would transmit if we did wash our hands. With our first experimentation, the group noticed that there was a lot of bubbling in the peroxide after it had been passed down from person to person. However, it was noticed that the bubbling of the peroxide took much longer periods of time depending on the person. For example, the sample from person 1 bubbled slower than the sample from person 2 since less yeast was present on the coin. The second experimentation, the group noticed that touching the coin or touching one of the fingers the coin touched had a different effect, since some yeast was transmitted onto the coin, as opposed to the person rubbing the coin. The finger that touched the coin seemed to have a lot more yeast on it than the group member who touched the finger that rubbed the coin. The group member that touched the coin had a lot more bubbling in the peroxide that would be represent the transmission of bacteria. However, the group member who touched the first group member’s finger had the same amount or slightly less bubbling in the peroxide than the group member who touched the coin.

With the understanding of these concepts we can calculate or hypothesize for the properties of each element or compound. Oxidation involves the gain of electrons of hydrogen or the loss of oxygen or decrease in oxidation state.

The information is called sensory information and it may or may not lead to conscious awareness. If it does, it can be called sensation. The purpose of this experiment was to conductRead MoreLab 2.

The Gravimetric Determination of Chloride in a Soluble Sample Introduction: For the experiment you will obtain an unknown sample, containing chloride ion, and perform the gravimetrical procedure using the sample of the analyte. An analyte is a chemical constituent that is determined from analytical techniques. The technique used in the experiment is the gravimetric determination analysis which is a method of quantitative chemical analysis in which the key constituent being sought afterRead MoreThomas Alva Edison: The Man of a Thousand Inventions Essay1344 Words   |  6 Pagesstudent in school the only thing he enjoyed doing was reading science books and self exploring. The teachers thought he was a mixed up kid so he dropped out and was home schooled by his mother. By age nine he was an excellent reader and loved to experiment from the things he read in the science books. His mother was his biggest supporter. From the ages nine through twelve he had read many chemistry books one in particular was called a school compendium of natural and experimental philosophyRead MoreFunctions Of Human Sensory Biology1631 Words   |  7 Pages Sensory Biology Lab 6 Name: Dominic Siaw Biology 132 T.A: Marian Wahl Date Performed: 4/7/15 Date due: 4/14/1 Abstract In this laboratory students will perform various experiments to demonstrate various properties of human sensory biology. Students worked in pairs and performed 5 experiments.
