Bread Mold Experiment Mold is something that we often take for granted‚ as something that makes us have to throw the bread away or the cheese smell bad. Mold is‚ in fact‚ a fascinating organism which has had many different uses over the years and our lives would not be the same without it. Most of us know that food seems to become moldy more quickly in the summer than in the winter when it is colder. Food in refrigerators seems to keep longer than food left out in the sun. Is this true? Does temperature

The main focus of this experiment was to find the relationship between temperature and the enzyme activity of amylase. This was achieved by attaining amylase enzyme‚ starch solution and potassium iodide (determines if enzymes hydrolyses the starch solution)‚ water bath and a hot plate. The temperatures used for this experiment were room temperature‚ 37oC‚ 60oC‚ 80oC‚ and 90oC. The hypothesis developed was that as the temperature increased‚ so will enzyme activity. Therefore‚ the ability of the

Consider a steady two-dimensional flow of Maxwell‚ Jeffrey and Oldroyd-B nanofluids over a cone having radius and half-angle . x-axis varies along the surface of cone and y-axis is perpendicular to it. The temperature and concentration distributions are vary along the surface of the cone. A variable magnetic field is applied along -direction as shown in Fig.1. A variable temperature along with the thermophoresis and Brownian motion effects are taken into account. and are the ambient temperature

perform better when they are participants in an experiment. Individuals may change their behavior due to the attention they are receiving from researchers rather than because of any manipulation of independent variables. The Hawthorne experiments took place from 1927 to 1933 in the Hawthorne plant of Western Electric. They wanted to test scientific management. The experiments were held by Elton Mayo‚ and a few of his colleagues. The experiments began as a series of productivity studies from

bubbles. So that’s why we call it a lava lamp inside of bottle. The conclusion is that you can make lava lamp household items if you use Alka-Seltzer‚ water‚ food coloring‚ and vegetable oil. So if you want to try just do what we did. That is our experiment. Why this happened because the Alka-seltzer had a chemical reaction beacuse of some powder on the outside of the alka-seltzer so the bubbles carried the food coloring up to the top of the bottle

The objective of the experiments is to see if mold will grow on bread if it has water. Molds are found everywhere. They are a type of microscopic fungi that lives on organic matter. They can be found both indoors and outdoors. No one knows how many species of fungi exist but estimates at least three hundred thousand or more. they have been on this earth for millions of years and believe to grow where there is moisture. According to the U.S.D.A eating bread with mold can cause allergic reaction and

The testing for the Doll Test OR Eye Color Experiment resonated more with children is because children are brought up in discrimination house hold. Doll test told that how equal size the dolls were except for their color‚ to test children’s racial perceptions. Their subjects‚ where at least the children between the ages of three to seven‚ were asked to identify both the race of the dolls and which color doll they prefer. Eye Color Experiment talks about on how children treated each other by eye color
