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…

Introduction: Enzymes have a huge effect on the human body and other organisms. Enzymes are catalysts that are used to accelerate the reaction process by lowering the activation energy. For this experiment the catechol oxidase was extracted from potatoes. The enzyme is called catechol oxidase because the oxygen is reacting to catechol. Catechol oxidase causes the browning of the fruits and vegetables because the compound is toxic to the bacteria. The purpose of this experiment is to…

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…

Introduction: Aerobic cellular respiration is the process in which energy is being released from organic compounds by chemical oxidation. In this lab we compared the change of the consumption of oxygen in germinating peas as it underwent changes in temperatures of either ten degrees Celsius, or 22 degrees Celsius (room temp.) to the oxygen consumption of dried peas as it also underwent the same temperatures of ten and 22 degrees Celsius. I hypothesized that the germinating peas would consume…

Introduction: There is a direct relationship between temperature and pressure in gases. The relationship can be proven by measuring pressure, which is measured with a pressure sensor, and temperature, which is measured with a temperature probe. Two areas remain constant throughout this experiment, which are volume of the gas and the number of molecules the gas itself contains. In this experiment, using the constructed apparatus, an Erlenmeyer flask with an air sample will be placed in four…

Intro to EWB: The EWB challenge is devoted improving lives, “Welcome to Engineers Without Borders (EWB) Australia. We 're here to engineer a better world, (Engineers Without Borders Australia, 2016).” The challenge they set before themselves is to allow everyone to lead a life without poverty through engineering knowledge and resources. “We connect, educate and empower people through humanitarian engineering. Humanitarian engineering uses a people centered, strength based approach to improve…

Introduction: Based on preliminary research, the hypothesis of the present study was that at temperatures higher or lower than 40 degrees Celsius fermentation is inhibited. Alcoholic fermentation is used in food production such as brewing, winemaking, and baking (Campbell). Thus optimizing fermentation and understanding the effect of various environmental factors can have important economic and social benefits. The production of CO2 is being assessed to show the rate of fermentation at certain…

After doing some research, I looked at a number of issues effecting the environment which are caused by humanity in its relations with the earth and life on it. There were discussions conducted and utilized readings which were assigned to different topics involving the environment. The main focus evolved around climate change; the causes and possible outcomes. However there are more problems on determining the ethics of our solutions than actual solutions. What are we doing to protect the…
