Energy | 1/28/19-2/1/19


Summary:

       Kinetic energy is energy an object has due to its motion. Potential energy is energy that is stored and waiting to be used later. Three types of potential energy are gravitational potential energy, elastic potential energy, and chemical potential energy. Gravitational potential energy is potential energy due to an object's position. Elastic potential energy is potential energy due to compression or expansion of an elastic object. Lastly, chemical potential energy is potential energy stored within the chemical bonds of an object. The formula for finding 0.5(mass x speed2). The formula for finding gravitational potential energy is mass x height x gravity. Both potential and kinetic however are scalar quantities meaning that they do not have direction. Both also are measured with same metric unit, this unit is known as Joules.
One of the Charts From the Simulation that I Computed

S&EP 5-Using Mathematics and Computational Thinking:

       I used mathematics and computational thinking when using simulations and when conducting an experiment. I used math to find distances traveled, averages, kinetic energy, and potential energy. I also used mathematics to answer questions based on my findings that came from computing numbers. For example, in one simulation that had to due with kinetic energy, I launched an object from a catapult. The object's mass was 7500 kg and its speed was 10 m/s. This ended up resulting in a kinetic energy of 3800 Joules (I also had to convert the 3800 from scientific notation). I then changed certain variables such as the mass of the object and/or the speed and computed the results with those as well.

XCC-Cause and Effect:

       The cause and effect relationship that I identified this week has to do with kinetic energy. More specifically mass and/or speed along with energy output. The cause being mass and/or speed with the effect being energy output. I identified this relationship when computing math during a simulation. During this simulation I came to the conclusion that the the greater the mass, the greater the energy output and the greater the speed, the greater the energy output. Similarly, the smaller the mass, the smaller the energy output and the smaller the speed, the smaller the energy output. In closing, the cause and effect relationship I identified this week has to do with kinetic energy where the amount of mass and/or speed affects the energy output.

The Sulfur Cycle 1/20/18

Image
Summary:        This week in science we learned about biogeochemical cycles, more specifically, I learned about the biogeochemical cycle known as the Sulfur Cycle. What I now know about the Sulfur Cycle because of what I learned this week through research is each part in the sulfur cycle. I also now know that their are a lot of different parts in the sulfur, but my focus was trying to make this complicated cycle very simple and easy to understand. The first part in the Sulfur Cycle is  Hydrogen Sulfide Gas is released into the atmosphere by the eruptions of volcanoes, hot springs (“ spring produced by the emergence of geothermally heated groundwater that rises from the Earth's crust. ”) , and the decay of living biological sulfur-containing materials in swamps, bogs, and tidal flats. Sulfur is also released from the ocean in sulfur-containing compounds in sea spray, and as the gas hydrogen sulfide. I also know that most of the sulfur released from the world's oceans does so

Plate Tectonics 3/10/18

Image
Summary:        This week in science we learned about Plate Tectonics. Plates have been on Earth for thousands of years and are consistently moving (very slowly). Through this the Earth can recycle our land, by destroying the old land, and creating new land. These plates are made of rock and are in the lithosphere layer of the Earth. Another thing I know is that there are 3 different type of plate boundaries. Those three types of plate boundaries are convergent boundaries, divergent boundaries, and transform boundaries. Convergent boundaries are when two plates collide and their are two different types of convergent boundaries. The two types of convergent boundaries are collisional boundaries and subduction zones. A collisional boundary is when two plates with the same density collide. Because they are the same density the plates buckle and warp. The land then pushes up into jagged peaks forming a mountain. Subduction zones are when one dense ocean plate converges with a lighter con

Analog Vs. Digital debate - WAC 3 Argument | Nicolas Reed-8th Grade Science

nreed1005 Ms. Garcia Science 8 4/5/19 Digital is Better than Analog        “There's an ongoing flood of new LP releases (Amazon currently lists 938,000 LP titles ). Kings of Leon, Taylor Swift, Nine Inch Nails, and Kanye West all have their latest releases available on LP.” according to the article titled, “Why does analog sound better than digital,” by Steve Guttenberg. Digital is better than analog. Digital allows you to have a clearer sound that is controllable and can last forever. Most importantly, it is cheaper, which means that it can used by almost anyone. Analog is the past, we must invest in the future and use digital.        Using digital means having high quality sound that can be manipulated. “Digital has certain perfect things about it [, it] immediately solved all the problems of analog background noise, hiss, where pitch control all of those things.” according to the video titled, “Analog or Digital? (1993),” from PastVid. Digital allows you to have “go
