Evaporation

While many people focus on saving water by turning off the sink while you brush your teeth and taking shorter showers, the focus is shifted away from how much water irrigation and other agriculture techniques use. Today developed countries have started to try and conserved water through various methods and inventions such as, water saving toilets, sinks, and showers. One of the major areas that we do not think of water waste is agriculture, one of the biggest uses for freshwater in the world.…

For my project, I chose to make an illustration. In the picture I have a breast cancer ribbon, a pot of boiling water, a prokaryote, a chromosome, a pedigree, and a factory to represent human impact, a flower to represent photosynthesis, a food chain, an energy pyramid, an embryo, humans evolving, a biomolecules chart, and the phases of mitosis. I drew a breast cancer ribbon because we talked about different types of cancer. There are many factors that go into the diagnosis of cancer. A lot of…

Freeze-drying well known and developed technology for preserving food and retaining its properties such as flavor, and taste. In this study, the objectives to investigate the difference between fresh, treated, and controlled freeze-dried samples and see the effects on those samples. Browning of the samples was one of the concerns to monitor and observe. The outcomes of this study suggested that the freeze-drying is great technique in preserving the food with its properties remain intact. This…

Hydropower is power that is generated from a dam by making water fall from a certain height behind the dam to a power plant that is lower in height. As a result, the water behind the dam has gravitational potential energy, which is converted to kinetic energy as it falls to the power plant. The power plant uses its turbines to convert the kinetic energy to electrical energy. In this assignment, we are figuring out “to what extent can hydropower meet the electrical energy needs in the United…

As mentioned above, the research about ABE as an alternative fuel is still in the early phase. Most research deals with the combustion and emissions performance of ABE-diesel blends in diesel engines, while the study about SI engine fuelled by ABE-gasoline blends is still not sufficient. Nithyanandan et al. (2014) [223] undertook preliminary investigations of the per-formance and emissions of a port-fuel injected SI engine fuelled with ABE and gasoline with volumetric ratios of 0%, 20%, and 40%…

Air pollution can result from both human and natural actions. Natural events that pollute the air include forest fires, volcanic eruptions, wind erosion, pollen dispersal, evaporation of organic compounds and natural radioactivity (http://eschooltoday.com/pollution/air-pollution/causes-of-air-pollution.html). One cause of air pollution from humans is the burning of fossil fuels. Sulfur dioxide emitted from the combustion of fossil…

Personal Truth Paper I was five. My mother was desperately trying to teach me how to skip rocks across water, and true to my uncoordinated tendencies, I was failing miserably. With great frustration, I decided to plop down on the grass and watch as she made five, six, seven skips on the surface of the water before the rock went plummeting down into the depths of the dark lake. Each little bounce of the stone rippled the water all the way to where my toes were resting in the cool waves. Such…

previously, therefore we cannot be praised or blamed for anything as we did not make that decision. An example of this is that rain cannot be praised or blamed for falling, it cannot be blamed as this is already predetermined by the process of evaporation into the clouds that must go somewhere. Likewise an alcoholic cannot be blamed for being an alcoholic as he was already predetermined to be an…

The Control of Nature, by John McPhee, is a book about three different events in which humans were faced with the challenge to “control nature” in order to protect their homes and lives. The three chapters in the novel, “Atchafalaya”, “Cooling the Lava”, and “Los Angeles Against the Mountains” illustrate some of the Enduring Understandings of Earth Science, which include “Energy, from the Sun and form the Earth’s interior, drive all of the Earth’s cycles and processes.”, “Matter moves through…

reservoir. Once the system is operating with the nutrient solution mixed with the water, it only needs to be checked every 1-2 weeks. The water continuously cycles through the system, using far less water than watering soil frequently. Also, less evaporation occurs in the tube system, so that leaves even more water than can be reused. Another reason that it is more efficient is that it takes up less space. Many hydroponic systems are grown vertically, taking up significantly less land space than…
