The objective of the Investigating Mixtures Lab was “To observe that not all liquids behave the same way when mixed with other liquids”. Before we started the lab we we each created a hypothesis mine was “If the water and vegetable oil are mixed and the two combine and make a mixture, then the vegetable oil will float and the water will sink”. This is the important information which we must solve to determine whether our hypothesis was correct.…

    Asphalt Puddles Essay

    A parking lot riddled with pools of standing water does not present an inviting welcome to your customers, tenants or employees. However, many people overlook the more sinister nature of puddles. Pedestrians could slip and fall, particularly if the puddles freeze, or drivers could skid on the water. Furthermore, water standing on top of asphalt pavement poses a risk to the integrity of your parking lot. If there is even a tiny crack in the pavement, the water will find a way to penetrate to the foundation. Once it does, it can erode the pavement's base, which can lead to costly repairs.…

    trace evidence

    The presence of trace evidence is particularly dependent on its persistence, as some particles and substances will remain on a surface more readily and for a longer period of time than others. The amount of time evidence will persist for depends on the size and shape of the particle, the amount deposited, activity between deposition and recovery, the nature of the environment, and the amount of time passed. Small particles will persist for longer than larger particles, as they are more likely to become lodged in the surface material. Irregular surfaces, such as certain fabrics and wood, will collect particulates more readily than…

    The Impact of the Agricultural Revolution

    The Agricultural Revolution was the beginning of a chain of events that led us to where we are today. Without inventions such as the Horse Hoe, we might not have modern day tractors and plows. Because of the better farming techniques, there became an excess of food produced. With less emphasis on ensuring that one would have food, people branched out and found a profession besides farming. The Agricultural Revolution was one of the most important events in modern history because it was the beginning of using technology in farming, it produced extra food, and it helped form a greater division of labor.…
