Introduction: Hot packs work by dissolving a salt, such as calcium chloride, in water to create an exothermic reaction. When salts are dissolved in water it requires energy to break their bonds apart, but energy is also released when the ions are surrounded by the water molecules. If more energy is released than is required to break the bonds, the reaction will be exothermic and will produce heat. In hot packs the water is kept separate from the salt, and when it needs to be activated, they are…

We see trash every day without paying attention. At times we don’t even realize how much trash is thrown away daily. It can be as small as a toothpick, to as big as a vehicle. If you live in a country like the United States of America where plastic, batteries, and other things are thrown away daily, chances are that an average family of four people, can produce as much as twenty pounds of waste per month. People just throw away trash without knowing where that stuff will end up. Solid waste…

Introduction The goal of this experiment was to determine atomic weight of Kandimonium and the relative number of M&M’s in Kandimonium. Kandimonim is composed of three isotopes: Skittles, M&M’s, and Sweet Tarts, and the ratio of Sweet Tarts to Skittles is 27:18. The relative number of M&M’s and the atomic mass were determined by weighing each of the different Isotopes and calculating their average masses for further calculations. Calculations The following calculations were used to…

By 1913, former President Theodore Roosevelt had been out of the White House for four long years, his bid for a surprising third term ended in a defeat to Woodrow Wilson when he is forced to run as a third party candidate and now he's lacking a sense of purpose. He jumps at the opportunity to journey to Brazil as part of a scientific journey of discovery sponsored by the American Museum of Natural History in New York City. During the planning stages, the trip undergoes changes from one that…

aqueducts) it will be possible to explain how these technologies have evolved and caused change in our society today. These changed society by providing order, keeping time, transportation (human and goods), discovery of new land, and supply of fresh water to humans and natural resources which without we would not exist, with timekeeping effecting us the most today. At the time the aqueducts changed the society in many ways and was a…

Bacteria They are formed by a single rudimentary cell. They have no nucleus or plastids, but chromatin. Some have assimilators pigments. They are on earth, water, and air, and can generally move. They may be causing disease and therefore are called pathogens. Those that do not cause disease are called saprophytes. In some cases, they are even useful, as in digestive processes or synthesis of vitamins. By the way, they are called coconuts when circular; bacilli if they have the form of rods;…

Many living organisms rely on the environment for essential resources, including water, food, and shelter. However, they not only need the help of the environment but also other species that live within the biosphere. This lab aided in demonstrating how the affect of one organism has on another, and whether or not it benefits either organisms or one organism. In order to progress with the experiment we first have to identify our variables that will be used during the experiment. The independent…

You then see the ocean, looking nice and cool and a sudden burst of confidence runs through you as you take your time stepping off of the boardwalk and into the sand. The sand is hot for the first few steps but the idea of stepping into that cool water is keeping you walking. A few more steps and you start to get the feel of the sand and it becomes easier to handle. You see others along your path and befriend…

Motionless, silent, I floated amongst the algae and the cool calm water embraced me. (Opening Adjective) Before the tale of the frog king begins, a little history lesson is in order. Around ten years ago, my family owned a sixteen-acre property in Grand Haven. The land consisted of two large ponds, both filled with countless fish, turtles, and other fascinating organisms. On the adjacent side of the farthest back pond, a tall tree house stood looming over the land. A kind of watchtower of the…
