The Effect of Varying Temperatures to the Rate of Respiration of Bufo marinus Statement of the problem: At which environmental temperature‚ do toads have the highest respiration rate? Most animals obtain oxygen‚ which comprise 21% of the air‚ from the environment. Oxygen combines with hemoglobin of the blood to form oxyhemoglobin. Oxyhemoglobin is transported to the tissues where oxygen is released and used for the metabolic functions of the animal. The functions produce waste materials‚ such

Investigation into how the focal length of a lens affects the temperature at the focal point Research & Rationale: In my project I will be looking in to how different lenses with varying thicknesses and therefore focal points magnify and intensify light passing through it. To do this I will be measuring the temperature of an object behind the lens‚ at the focal point. The study and research of lenses was not part of the course this year‚ so I thought it would be more interesting to study a new

If you were Italian and somebody called you a “Wop”‚ what would you do? If it were me I would feel very angry and offended. In the essay “I Just Wanna Be Average” being called a “Wop” or being physically abused happened frequently. Written by Mike Rose‚ he shows us how badly he was treated by his teachers in high school. In the beginning of this essay‚ Rose describes how his teachers treated him in his early years of high school. Rose’s choice of phraseology when characterizing his teachers is

Totally Too Many Tests Typically‚ the average high school student graduating in the spring of 2015 in the state of Texas will have taken roughly 35 state-mandated and college entrance exams. Every single one of these tests‚ including‚ but not limited to‚ the SAT‚ ACT‚ PSAT/NMSQT‚ Subject Tests‚ TAKS‚ and STAAR exams are considered to be standardized tests. By standardized‚ these means they were all administered and scored precisely alike‚ and give an average score. As our society advances and the

The average of workweek Because we are in 21 century‚ most of companies force workers to work more than 10 hours in a day which means more than 50 hours in a week to get more products in less time‚ and most people spend all their time work to get more money. However‚ the average workweek should be no more than 30 hours. Workers who spend more than half a day working will feel tired‚ especially if they don’t work in offices‚ and they will not be able to do any other activates even in their weekends

Experiment 16: Heat conduction Introduction In this laboratory you will study heat flow across a temperature gradient. By comparing the temperature difference across one material to the temperature difference across a second material of known thermal conductivity‚ when both are conducting heat at a steady rate‚ you will be able to calculate the thermal conductivity of the first material. You will then compare the experimental value of the calculated thermal conductivity to the known value for that

we hear and are caused by vibrations that travel through mediums. Depending on the medium and temperature‚ the time it takes for sound waves to travel vary. The hypothesis states that if the temperature in the air increases‚ then the speed of sound will also increase because faster-moving particles transfer energy quickly. The data collected supports the hypothesis. Therefore‚ increased air temperature affects the speed of sound because the molecules move faster‚ which causes the energy to be transferred

Investigating the effects of temperature on cell membranes Independent variable: Temperature of beetroot Dependent variable: Absorbency of light Hypothesis: As temperature rises to its optimum temperature‚ the absorbency of light will increase because protein is an enzyme and will therefore be affected by temperature. This is because more beetroot dye will pass through the cell membrane and then into the distilled water. The deeper the colour of the beetroot dye‚ the higher the absorbency

spectrum of sunlight yields the highest temperature? My hypothesis is that the blue/violet part will have the highest temperature. The blue/violet part has the highest frequency out of all the colors on the visible light spectrum and it also has the highest amount of energy. Therefore‚ I hypothesize that it will have to the highest temperature as well. After conducting the experiment‚ I noticed that during the duration of five minutes‚ the temperatures of all four thermometers increased. The

How can the specific heat capacity of water be used to regulate temperature? Specific heat capacity is the amount of energy needed to increase the temperature of an object by 1˚C. The formula that uses specific heat is Q = mc∆T‚ where Q is heat energy‚ c is specific heat‚ and ∆T is the change in temperature. The amount of heat energy depends on the mass‚ or the size of an object‚ and the specific heat capacity‚ which depends on the substance it is made from. The specific heat capacity of water
