First we chose an unknown metal, in which our unknown was unknown metal 2, the metal was gray and irregular shaped. We setup the calorimeter and got a mass of it just being empty then we got a mass with 30mls of water in it. We found the mass of the water by subtracting the mass of the empty calorimeter which was 49.987g and the mass of the calorimeter with water which was 87.332g and got the mass of just the water 37.345g. The metal was placed in a test tube 5cm high and we got the mass of the empty test tube that was 42.703g and then with the metal in it and it was 72.607g. We heated the 300ml of water to a boil, then placed the metal that was in a tube and waited 10 minutes before we took it out. The temperature of the water before the metal was placed was 20 degrees Celsius, when we put the hot metal into the water and stirred it with the stirring rod it was 29 degrees Celsius, the change of the temperature after the metal was placed was 9 degrees. We ran this experiment twice to compare the results. In the second experiment we found that the mass of the calorimeter and water with 50mls was 100.033g and the empty calorimeter was 50.857g. We subtracted them two and we got the mass of water was 49.176g. The temperature of the water before the metal was placed in was 21 degrees Celsius and then when the metal was heated up for 10 minutes the temperature went up to 28 degrees Celsius. The change in temperature in the second trial was 7 degrees Celsius.…

The Mission Blue Butterfly (Icaricia acaricides missioners) has lived in Northern California, and butterfly species are threatened. “the Mission Blue Butterfly was declared as endangered on June 1, 1976, by the U.S Fish and Wildlife Service under the Endangered Species Act (ESA)”. areas the threatened species is protected inside habitat Those renovations. For example, the Mission Blue Butterflies have survived because they eat lupine leaves. The available amount lupine is a smaller amount since they are several non-native species that hurt the growth of the lupine including fennel, and the Monterey Pine. if the lupines die, the butterflies will too. These plants so fast, the lupine does not have any suitable sunlight and water. These plants…
In the experiment there will be several variables that I need to try and control, the temperature of the water is one of these because if the temperature is higher or lower on the day the results may end up being higher or lower, this would make my results inaccurate. I need to try and limit the human error in the experiment as the daphnia heartbeat is very quick so it will be hard to be completely accurate so we are using the blind method.…
In this experiment, a device that measures heat, a calorimeter, will be used. For this experiment, a calorimeter will be made with two nested Styrofoam cups, cardboard to cover the top as a lid, a thermometer, as well as about 25mL of water and about 7g of NH4¬NO3. The temperature of the solution will be closely monitored with the thermometer.…

Each trial we had to calculated how many breaths of the fish for a full minute and record the data. First, we got the temperature of the beaker and lowered the temperature of the water. Second, on trail one, we added crushed ice and wait a minute for the fish to adjust. Then count and record the number of breaths the fish takes within 1 minute period at each…
Ectotherms are “cold-blooded” animals such as reptiles, amphibians, insects, fish and worm. These animals rely on the outside environment for their body heat as they do not generate heat internally like a mammal or bird. Ectotherms have a variety of adaptations, many of them behavioural, to regulate their body temperature and keep it within the range in which they can be active; 10-30oC…
Ectothermic animals are animals whose body temperature is affected by their surroundings. This means that if the environment is cold the animal will be cold. If the environment is warm the animal will be warm. This is because the animal doesn’t have the capability of regulating its body systems to keep a constant body temperature. When an ectothermic animal is cold, its heart rate will lower. When the animal is warmer, the heart rate will raise – as long as the temperature isn’t sufficiently high to harm the animal. (Campbell, 2005)…

Endotherms are organisms that maintain a stable body temperature. The environment has little effect. Endotherms consume different resources to maintain a stable body temperature trough changes in their metabolism. Ectotherms are organisms that cannot maintain a stable body temperature on their own. Ectotherms depend on its environmental surroundings to stabilize its body temperature. Stabile body temperatures are very important for Ectotherms in order for them to perform their day to day activities. Ectotherms are affected by the environment in many ways. Ectotherms body temperature can change very easy under certain conditions. Radiation, convection, conduction, and evaporation are the main types of temperature transfer on ectotherms. Anything from the organism coming in contact with a hot surface to hot sun emitting its radiation to a cold wind breeze just blowing by. Because ectotherms are so highly and easily influenced by their environment it is important for us to understand their ways of controlling it. In this experiment we will understand the differences in which ectotherms control their body temperature. We will understand differences in behavior of an ectotherm and differences in morphology. We will test the differences in behavior by placing identical model ectotherms (marshmallow peeps containing data loggers that record time and temperature.) in a wet shady location and a dry sunny location. Then for the morphology side we will test the differences in peeps with a white fur coat and ones with feathers in a damp dark hole under a tree away from sunlight. It is important to put them in a hole or retreat place because it is rarely thought of during these experiments. “Many terrestrial ectotherms behaviorally regulate body temperature (Tb ) during periods of aboveground activity by exploiting spatial and temporal variation in microclimates” (Cowles and Bogert 1944, Porter et al.…
There are many thoughts on the various types of stretching used in an Athletic Training environment. Often people are attached to one method or another based on what their personal experience has been. With all of the various methods I began to wonder what makes Proprioceptive Neuromuscular Facilitation (PNF) so special; why is it that in every clinic where I have spent time, PNF is the preferred method. Furthermore if it is used so frequently is it a matter of personal preference or is there research to back up its effectiveness. Because of these questions I chose to find the answers to the question, “Does the use of PNF on lower extremity injuries increase tissue extensibility?”…
Throughout the course of American history, the late 1700s and early 1800s were the main eras when the abolition of slavery was most rooted for. After the Haitian Revolution, in which the former state of Saint Domingue freed itself from the rule of the French colony, abolitionists around the world began to rise up and form organizations and societies to grant freedom to slaves. Although it was an informal and gradual process, anti-slavery movements were successful through votes in Congress, consistent petitions, passed laws, and published literature. Most interestingly, both whites and blacks were involved in the abolitionist movements, and believed that the use of slaves was destroying the unity of the nation. One of the earliest and most notable…
