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. One of the most popular activities in the park is to observe the vast number of species. The park was created in 1915 and its area is 415 square miles. Carbon Cycle: The carbon cycle is the processes by which carbon is transferred throughout an ecosystem. In a typical carbon cycle, carbon is released in the form of carbon dioxide…

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…

Pollution has been impacting the Earth for multiple years. In Visit Sunny Chernobyl, Andrew Blackwell travels around the world to some of the world's most polluted places. Blackwell asks if the human race destroying the Earth with all the pollution that we have been creating. In the book Visit Sunny Chernobyl, Andrew Blackwell travels to Chernobyl, Fort McMurray, Port Arthur, The Great Pacific Garbage Patch , The Amazon Rainforest, Guiyu & Linfen, and the Yamuna River, which are some of the…

on the coin, and was put on the coin in 1909 (pennies.org). The penny was the first U.S. Cent to include the words “in God we trust” (pennies.org). Now how do they become dull and dingy? Pennies become dirty because their copper. The copper and oxygen mixes to form copper oxide. Copper oxide is also known as cuprous oxide. Cuprous oxide occurs naturally in some parts of the world as cuprite (wisegeek.org). Cuprite is used in many other substance such as glucose and some types of sugars.…

Purpose: To find the pH of different household items and to see what substances are acids or bases. To see how different substances neutralize each other. Hypothesis: I hypothesize that cleaning products will be bases and foods and substances we ingest will be acids. Materials: • Oil • Finesse Shampoo • Anti Freeze • Drain Opener • Hand Soap • Vinegar • Oxy clean • Pine-Sol • Hydrogen Peroxide • Apple Juice • Ammonia Procedure: 1. All materials were gathered, and safety goggles were put on.…

The Effect of the Light Source Distance on the Photosynthesis Rate of Spinach Leaves Introduction: We studied the reaction rate of photosynthesis of spinach leaves from various distances from the light source. Our experiment followed the Biology 152 Photosynthesis Lab. We varied the distance from the leaves and the light source. Our distances we tested were 0, 12, and 24 inches from the light source. This experiment is important in the real world in green houses. The goal is to have plants…
