Chemistry Investigation Folio: Practical – Galvanic Cell Name: YY Names of Partner: ZZ Part A Investigation Design Proposal: Purpose of Experiment: To determine the effect of concentration of reactants on the current produced by a galvanic cell. Hypothesis: The greater the concentration of solution in the two half cells reacting with the two metals to produce current‚ the greater the flow of current will be produced from the galvanic cell. Independent Variable: Concentration of both reactants

Beet Cell Lab Purpose: The purpose of this Lab was to see how much pressure or stress the beet tissue would hold. Hypothesis: I hypothesize that the higher % of the solvent that the higher the colour intensity will be shown on the ph colour scale. The lower the solvent then the less colour shown. Materials: *Test Tubes (4) *Cork Borer *Beets *Water *1% Acetone *50% Acetone *1% Methanol *50% Methanol Procedure: *Cut 4 uniform cylinders of beet using a cork borer with a 5-mm

microscopic objects such as cells. The first to accomplish this was Robert Hooke when he used a light microscope to observe a thin slice of cork. Hooke observed that the cork was made of tiny structures of which he called cells. Hooke was in fact looking at the cell walls of dead plant cells that make up the cork. After Hooke‚ a Dutch scientist named Anton van Leeuwenhoek used the light microscope to observe living cells inside stagnant rain water. This then developed the cell theory in which all living

Avatar One of the most interesting aspects of the movie Avatar is the culture that makes it up. The Na’vi is an entirely made up and brand new culture with language‚ norms‚ relationships‚ religion‚ and beliefs. Western civilization tries to move in on their land and their ways‚ believing the Na’vi are savage and primordial who must be living in the past due to their lack of modern technology uses and spending their every day and night in nature. The Na’vi have very close ties to their ancestors

research of direct reprograming of a stem cell the “Pluripotent stem cell” (iPS) How it was discovered and the incredible ability it has to transform into any other tissue in the human body. Along with the trials and tribulations scientists had to go through generating iPS cells like the protesting and strict laws against using ES Cells due to the fact that the ES Cells are derived from the inner cell masses (ICM) of blastocysts also known as Embryonic Stem (ES) Cells and the embryos possibility of one
