element or compound reacts with oxygen to produce energy in the form of heat and light. It is a reaction that requires oxygen. My objective in doing this experiment is to determine the effect of the height of the candle on the length of its burning time. The existing problem is Suffocation. Research Problem: What is the effect of height of the candle on the length of its burning time? Hypothesis: The shorter the Candle‚ The longer the time it will burn. Experimentation: A. Materials 1. 3 identical jars

Introduction Cell respiration is the process of a cell converting sugars into ATP (energy) in the mitochondrion. It is an essential process which enables organisms to survive and function (Biology Online‚ 2010). Not only does it produce ATP‚ but also carbon dioxide (though decarboxylation)‚ NADH and FADH and in the case of some organisms‚ alcohol. Saccharomyces cerevisia‚ a bacterium commonly known as yeast‚ is used in various aspects of life‚ from winemaking to baking. It respires both anaerobically

between temperature and light absorbance. The higher the temperature of the water surrounding the beetroot‚ the more coloured the water around the beetroot was. This is shown in the graph by: at 0°C‚ the water surrounding the beetroot was fairly pink and had an averaged amount of 0.074 absorbency. At 80°C‚ the water surrounding the beetroot was very pink almost red‚ and had an average of 0.982 absorbency. Conclusion The hypothesis was that beetroot left to diffuse at a higher temperature will have

4. Which city has the warmest annual temperature? The city of Vancouver has the warmest annual temperature. This is because of the Ocean currents together with the Wind and Air masses‚ and Vancouver’s Nearness to water. Latitude: Even though Vancouver is fairly south‚ it isn’t as southerly as many other places making latitude‚ not a cause. Ocean Currents: Ocean currents play a huge role in the average annual temperature of Vancouver. The Warm North Pacific current brings warm water towards Vancouver

The effects of environmental temperature on respiration rates of mice were observed in this experiment. I hypothesized that when environmental temperature decreased‚ the respiration rate of mice would increase. I predicted that if environmental temperature decreased‚ the respiration rate of mice would increase. The respiration rate of the endotherm was measured using the Qubit/Vernier system and the S152 CO2 gas sensor‚ a device that measured the CO2 concentration in the air. The independent variable

Two experiments were performed to investigate the effects of temperature on the growth rate pine seedlings. Experiment 1 A batch of 60 pine seedlings (Batch I) was grown in a greenhouse under controlled temperatures. Ten plants were grown at each of six temperatures from 50 C to 300 C. These plants remained at their original temperatures 24 hours each day for two weeks. All other conditions were the same for all seedlings. The growth rates are shown in Table 1. Table 1.

are exposed daily to oxygen (such as fruits‚ vegetables and animals). Background Information The Catalase enzyme in this experiment is known for being less affective the warmer the temperature is. According to “Science fair projects” an enzyme becomes unstable at higher temperatures and the shape of the enzyme changes. The enzyme is also used to remove hydrogen peroxide from clothing in the textile industry. This would make sense because when an enzyme encounters a substrate molecule

How does lava temperature impact viscosity and velocity? The higher the temperature the lower the viscosity which allows it to develop a smooth surface skin‚ but this is quickly broken up by flow of molten lava‚ it creates a rough‚ clinkery surface. The lower the temperature of the magma the higher the viscosity which allows the lava to travel down the slope. In the group the average velocity was 0.91 cm/s . How the “lava” flowed was in a high viscosity and a low velocity because the “lava” was
