tracked how often living rooms and bedrooms remained at or above ideal temperatures for optimum respiratory health. The study concluded that “people who lived in homes in which the living room temperature was more typically at least twenty-one degrees Celsius for at least 9 hours per day had significantly better respiratory health (that is‚ fewer exacerbations of their underlying COPD or respiratory infections‚ than subjects who lived in homes where this temperature was maintained less often”. The study

of the test tubes we will place 2cm of milk. Into test 1 and 3 we will add three drops of rennin. Into test tube 5 we will add 3 drops of boiled rennin. We will place test tubes 1 and two at room temperature and 3-5 in a water bath at 37 degrees Celsius. Test tube | Rennin | Environment | Result | 1 | 3 drops | Room temperature | Still liquid‚ the enzyme did not increase in rate of reaction‚ room temperature was not ideal. | 2 | None | Room temperature | Still liquid‚ the reaction could

When Hypothermia Sets In When the cold slaps your face and squeezes tears from your eyes‚ it could be the start of hypothermia. Nazi doctors calculated that a human can die when their body temperature drops to around 77 degrees fahrenheit. The lowest recorded core temperature in a surviving adult is 60.8 degrees fahrenheit (12). Instinctively‚ the web of capillaries on your hands constricts sending blood coursing away from your skin and deeper into the torso. Tibetan Buddhist Monks can raise

Introduction In thermo-fluid sciences‚ the measurement of temperature plays a key role. During this lab we tested two different types of thermocouples‚ a T-type and a J-type. Measuring with a thermocouple allows us to measure the temperature difference between two junctions. There are several laws that deal with the thermocouples and reading of temperatures. We use the first law of thermodynamics which states that there is a conservation of energy. Also the law of homogenous metals is in

Scientific Method - Mealworms Abstract The experiment is designed to determine which substrate‚ A (oat bran) or B (peat moss) will be better nourishment for a mealworm after exposed for 7 days. A total of 30 mealworms were placed in the substrates for a period of 7 days; 15 in substrate A and 15 in substrate B. The data was compiled and analyzed on day 7 to determine the change of mass in each of the mealworms. The experiment proved my hypothesis to be correct; the mealworms would not thrive

In this lab‚ I was testing different temperatures and how it affects the time catalase takes for it to break down peroxide. The problem that i was investigating is how does temperature affect the time it takes for catalase to break down peroxide. My independent variable for this lab was the temperature of the solution the enzyme is in. My dependent variable in this experiment was rate of reaction or the amount of time it takes to sink and rise. My hypothesis is that if the temperature is higher than

second step in cooking my family’s homemade lasagna is to prepare it. Lasagna has many different ingredients that have to be cooked and mixed together at separate times. First‚ you need to preheat the oven to 375 degrees Fahrenheit or 190 degrees Celsius. Boil two and one half quarts of water in a 5 quart pot of lightly-salted water on medium high‚ add the noodles and cook them for approximately eight to ten minutes or until soft. Drain the noodles and put them to the side. Next‚ put the two pounds
