mechanism was studied using I-button data loggers placed inside marshmallow peeps to record temperatures in two different microhabitats; one in a stream and the other on the bank adjacent to the stream. Five samples were placed in each microhabitat and temperature was recorded every minute for 20 minutes. It was hypothesized that turtles in moving waters‚ such as streams‚ would exhibit lower body temperatures than those residing on banks alongside streams due to convection of the moving water. The

of a steady body temperature even under a variety of external conditions” Harvard. Based on the process of thermoregulation‚ animals are divided into two groups‚ ectoderms and endotherms. Ectoderms are animals that are poor thermoregulators‚ having their body temperature determined by the ambient temperature. Animals that fall into this category are reptiles‚ amphibians‚ and fish. On the other hand‚ endotherms are animals that can thermoregulate and keep their internal temperature constant regardless

When prompted‚ enter 0.0 *C as the actual temperature of the constant temperature bath (ice water). Press Enter. Insert the temperature probe in the ice water. Swirl the temperature probe until the temperature approaches and stabilizes near 0 *C (it may not read exactly 0 *C). Press Enter. 4. Remove the temperature probe from the

raising the temperature. Stir with a glass rod occasionally to make sure the heating is uniform. Measure 50mL of cold distilled water and place in the calorimeter setup. As the water is heating‚ also monitor the temperature of the cold water to find when it reaches equilibrium. Record the temperature of the cold water to the nearest 0.2°C. When the water being heated reaches 70°C-80°C‚ remove from the heat and let it sit on the lab bench‚ stirring occasionally. Record the temperature of the hot water

experiment was on the basis of the concentration of Potassium Hydroxide affecting the temperature of water that it is dissolved in. One person stirred in the different concentrations of Potassium Hydroxide while the other measured the temperature as it rose after the pellets dissolved. At times it was difficult to ensure that the pellets were completely dissolved within the solution. Raw Data Table: The temperature of water after dissolving different concentrations of Potassium Hydroxide in it. Concentration

investigate if stress affects body temperature. PURPOSE: Stress refreshes the hormones that affect the body in different ways. In this experiment‚ it will evaluate whether body temperature changes can be detected when people are placed in stressful situations. HYPOTHESIS: I think that when you are stressed‚ the body temperature will be affected because the more you are stressed out‚ the higher your blood pressure gets and then your blood heats up and the temperature changes. MATERIALS: Basal thermometer

from a cold temperature to room temperature; however‚ the rate of photosynthesis decreased in the body temperature. This means that the hypothesis was rejected. The rate of photosynthesis did increase‚ but only to a certain point. Based on these results‚ it can be concluded that photosynthesis performs better at room temperature that at cold temperature because thee low temperature slows down the reactions taking place in the chloroplasts. Photosynthesis performs better at room temperature than at body

thermometer is a device or instrument used for measuring temperature. There are many different types of thermometers; however each one is based on a physical property of a thermometric (temperature measuring) substance that differs in a measurable way with temperature. Some of the physical properties that vary with temperature are volume‚ resistance and color. A physical property that increases or decreases with temperature can be used to measure temperature. This is called a thermometric property. Liquid-In-Glass
