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.

Systems In a Human Body Info Paper 10/15/15

Friday and Monday we were writing down the definitions of (I believe) organelles that are part of the urinary and digestive system. Here are some examples of some of the organs my class had to write down the definitions for, the esophagus, the pancreas, the liver, the small intestine, and the large intestine. One thing that I forgot to add is that there was one other paper that had the definitions down for my class because I did not want anybody thinking that my teacher would make us write the definitions on our own out of the blue. The way we knew the definitions was because on Thursday or Friday I forgot which day any ways my teacher showed what every organ that we had to write the definition for what each organ did in order. But the fun part was she assigned every single person in my science class an organ to make it fun. What also helped was that Ms. J went over the answers with my science class also she allowed us to switch our answers if we got them wrong that especially helped

Chemistry Mastery Quest 2 Regrade

The Question I got Wrong Was: Reactions that involve burning are classified as I originally answered decomposition, the correct answer was actually exothermic. I realize now that exothermic is the better answer and was the correct answer. This is because exothermic reactions release heat causing its environment to get warmer. This creates a rise in the temperature which creates the burn. This means that exothermic reactions involve burning. This is why the correct answer was better than my original answer and is the best answer.

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
