Crayfish are freshwater crustaceans that use their claws called chelipeds,for warning off predators. When frightened, these crayfish lift their chelipeds to make threatening gestures, all while moving backwards or staying still. We examined how long it would take for crayfish to calm down once removed from the water and if the temperature had any influence to this observation. To do this, we placed two crayfishes in room temperature water and another two in colder water for an interval of five…

The Effect of Cellular Respiration at Low and High Temperatures Introduction Cellular respiration can include two processes, aerobic respiration and anaerobic respiration. The main purpose of cellular respiration is to breakdown sugars into smaller structures so that the cell can use it as energy (Reece, et al. 2014). The main concept of the respiration lab is aerobic respiration. This is the process that organic compounds will be degraded from oxygen to produce water, carbon dioxides, and…

Climate change is clearly evident in the world around us and it is having and will continue to have a major impact on our lives. Therefore, it is very relevant to analyze the changes in climate that have occurred in Howard County, Maryland such as the significant changes in mean precipitation and timing of precipitation, winter temperature and the summer precipitation. Furthermore, it is crucial to understand that many of these changes will be clearly seen in the relatively near future if…

“Are you alright?” my mother usually asks me that question whenever I get sick. Then she would touch my forehead and neck to check if I’m hot. She’d rush to our medicine cabinet and get the mercury thermometer, shakes it, and puts it in between my armpit. After two to three minutes, she’d get it and read what it says. “You’re sick, 39 degree Celsius” Mom said. Since then, I have asked my mother to teach me how to read the thermometer. Whenever there’s a family member who gets sick, it would be…

Background: Fishermen use many different types of baits and lures to attract fish of different shapes and sizes. One of these types that certain fishermen use are lighting devices that attract fish. Some fish may be attracted to illuminated lures because they live in poor visibility conditions and low light. It is also important to light the bait so the fish could see it. The brighter the light the better, but since electronic light devices are expensive and unreliable, glow sticks prove to be…

The process of heat-treating Knife River Flint requires a lot of time, preparation, and materials. The Knife River Flint that was used in this experiment came from Mercer County, North Dakota, which there are five different Knife River Flint Quarries in Mercer County. The three closest quarries to where the Knife River Flint in this experiment was collected are the Crowley Quarries, Medicine Butte, and Dodge Quarry. With the help of Russell Redhorn, a Native American monitor I was working…

Last Name: _____Adeline________________ First Name: ________Morley_______________ Film Review: Absolute Zero How did early concepts of cold change throughout the history? In 17th century Cornelius turned summer into winter at kings room with possibly the first air conditioning. Next Boyle used scientific process to study cold with a variety of experiments while it was believed cold was a substance. Boyle concluded heat was a form of motion, the cooler a substance is the less movement. Once…

same task. In analog thermometers the temperature is represented using the rising or falling of the liquid within the tube. In the process numbers are not processed like in digital technologies. In digital thermometers data is stored using ones and zeros. This data is then read into pictures, numbers, and letters. This makes digital easier to…

constant peak rate at around 11 mins for all test tubes. The data concludes that eighty degrees was the optimal temperature for the enzyme catechol oxidase; the peak value was between 3.2-3.3 nanometers. The lowest reaction rate was at temperature zero degrees celsius, the peak absorbance around 0.2-0.3…

Even today I still remember clearly what happened that fateful day. Why I did it, I’m not exactly sure but it wasn’t fun, at least for Patrick it wasn’t. I was back in 3rd grade, young, innocent, and having the time of my life. It was Spring almost Summer and it had been a decent year, nothing special but little did I know today was going to be exciting. This is when I lived in South Haven which had a population of like 10 people not including tourists. I would move to Kalamazoo in about one…
