States of Concentration 10/16/16


     This week in science we learned about high and low concentrations with water. We learned this by taking notes and doing an experiment. The most important thing I learned about concentration is what it means, and what it means for science is how much of a substance is in something. Another thing I learned about concentration is affects the shape of which that substance is in. For example if a cell has 90% water in it and 80% water on the outside of it than the cell will deflate because the water will move up and out of the cell (this means the cell is hypertonic). The last thing I learned about concentration is the 4 states of concentration and what they mean and what happens if that is the case. The 4 states of concentration are:


  • Osmosis-Movement of molecules from a low to a high concentration. That means the cell will stay the same.
  • Hypertonic-Lower concentration outside the cell than inside. The cell will shrink and deflate.
  • Hypotonic-Lower concentration inside the cell than outside. The cell will inflate.
  • Isotonic-Have the same concentration inside and out of the cell. The cell will stay the same.


S&EP 4_Analyzing and Interpreting Data-

      This week in science I created table that showed data of an egg experiment that showed the starting weight and ending weight. And after the results came in I analyzed them to see what state of concentration each egg was. For example one egg started at 101 grams then in the end it was 156 grams so I analyzed the data and figured that the egg is hypotonic, I figured that because the egg inflated a lot.

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
