Deforestation in the Amazon Did you know that it is said that within 100 years, there will be no more rainforests? The rate of deforestation is the same as the loss of thirty-six football fields every minute. One and a half acres of forest is cut down every second. Although it allows for people to generate more revenue, deforestation should be banned because it creates more carbon dioxide in the air, promotes the development of drought, contributes to the extinction of wildlife and is a limited…

This disagreement was about the pigments located in the stems and veins of a plant and the pigments located in the green portion of a leaf. Jan believed that only the stems and veins contained all of the important pigments except for chlorophyll. She believed that the green portion of the leaf would not contain all these other pigments. Mark, on the other hand, believed that the same pigments were also located in the green portion even though they were not visible. In order to determine who was…

The purpose of this experiment was to ascertain an unidentified substance. The substance in question was a colorless liquid with an odor resembling acetone. To start with the Tollens’ test was conducted on the unidentified substance to differentiate between an aldehyde and a ketone. The results of the test were negative. This indicated that the substance under consideration was a ketone The next step consisted of determining the melting point of the substance, which was in the range…

In, “Movement of Molecules in or Out of Cells” on page 159 to 163, it reads, “A student put a drop of blood on a microscope slide and then looked at the cells under a microscope. Initially the magnified red blood cells looked like little round balls, however after adding a few drops of sugar water to the drop of blood, the student noticed that the cells appeared to become smaller.” Now the question stands, why did the red blood cells appear smaller? There were three possible explanations…

Front Page: The Rocky Mountain National park in is Colorado. The elevation differences are vast and vary between 8,000 to 14,259 feet. The park is open year round.

Egg Drop Project For my egg drop project, at first I planned to do a triangle shape around the egg with straws and tape the straws together. Then I changed my project to a square like shaped with enough flexibility to squeeze the egg into it. I used straws because it would “soften” the fall. I also used a parachute to make it a smoother fall. After I completely figured out what I was doing I started building. I hot glued two straws against one straw until I had a square. After I…

Temperature was effective in goldfish number of breaths per minute. As water temperature decreased from 22℃ to 10℃, the average number of breaths also decreased. The mean of the average number of breaths is 69.24. The number of breaths in the study ranged from 16 to 135 breaths per minute. The null hypothesis, that the temperature of the water has no effect on the number of breaths per minute, can be rejected. The results support the alternative hypothesis. The control fish number of breaths per…

increase in the reaction rate. Since a product of this reaction is oxygen gas, it will bubble up through the liquid, into the syringe. The amount of oxygen gas present in the syringe at a certain point of time is proportional the rate of reaction (assuming the reaction is not complete), and so can be used as an indicator of the rate of reaction. Variables Independent: Amount of manganese oxide catalyst (g) Dependent: Amount of oxygen gas evolved (dm3) Controlled: Pressure, concentration of…
