Eclipses, Seasons, and Tides | 4/29/19-5/3/19

Solar lunar eclipse diagram by Tomruen

Summary:

       The positions of the Earth, Moon, and Sun heavily determine eclipses, seasons, and tides. For example, both types of eclipses are caused when the Earth, Moon, and Sun are aligned. Solar eclipses are caused  when the Moon is in front of, and blocking the Sun's light from reaching Earth. This results in not being able to see the Sun, or the Sun being partially blocked by the Moon. A lunar eclipse is caused when the Earth is in front of the Sun which blocks the light from reaching the Sun. Thus, turning the moon to a gray color or a dark red color depending on if the Moon is in the penumbra (gray) or umbra (dark red). Another example of how the positions of the Earth, Moon and Sun effect things is with tides. Spring tides (when the difference between the height of the high tides and low tides is very great), which have very high tides are caused when the Earth, Moon, and Sun are aligned in any position. This can mean that the Earth is in between the Sun and Moon, or that the Moon is in between the Sun and Earth. Neap tides (when the difference between the height of the high tides and low tides is very small), which have very low tides, are the result of the Earth Moon and Sun form a right angle.

S&EP 2-Developing and Using Models:

       This week in science we both developed and used models. We developed models when discussing the positions of the Earth, Moon, and Sun and how they effected eclipses, seasons, and tides. An example of this is when we had to create a diagram of when and where the highest point of the Sun was during the two solstices. We used models this week two help us better understand the subject we were learning about. The models that we used were simulations. One example of this is for one of the seasons simulations. This simulation allowed to see how the Earth's longitude, axis, and position in terms of the moon determines what season it is and when the solstices occur.

XCC-Patterns:

       The pattern I determined this week has to do with locations of the Earth, Moon, and Sun and how they dictate eclipses and tides. The main pattern I found was how the Earth, Moon, and Sun being aligned is what makes a massive difference to eclipses, seasons, and tides. When they are aligned in the order of Sun, Earth, and Moon, a lunar eclipse and spring tide is caused. When they are aligned in the order of Sun, Moon, and Earth, a solar eclipse and a spring tide again are caused. The other pattern that I found was the whatever season it is in Northern Hemisphere, it is the exact opposite in the Southern Hemisphere. For example, if it is spring in the Northern Hemisphere, then that means that it is fall in the Southern Hemisphere.

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

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
