     This week in science we learned about elements and ions through taking notes and completing an assignment. We learned about the components of how each element looks on the periodic table, the components are the element name, the element symbol, the atomic number, and the average atomic mass. We also learned what ions are and what types of ions there are. Ions are atoms that have lost or gained electrons. There are two types of ions, a cation and an anion. Cations are ions that have lost electrons which also means they have a positive charge. If you were to show that something is a cation you would have in superscript after you write the element an addition symbol with a number next to it representing how manh electrons were lost. This shows that they have lost electrons which means they have a positive charge. Anions are ions that have gained electrons which means they have a negative charge. You would write this in your superscript which is after you write the element you would have a subtraction symbol and a number next to it to show how many electrons were lost. This represents that because they gained electrons that their charge goes down which means that the element has a negative charge.


S&EP 6-Constructing Explanations & Designing Solutions:

     This week I constructed explanations because I every question I answered had to have an explanation. One of the questions was "how do you know if this is a cation and how do you know how much electrons was lost?" I had to design an explanation and give good detail on how I found the answer. I had to use the ACE strategy, I had to answer the question, then cite how I knew the answer, and extend my answer. Throughout every question I used the ACE strategy and answered the questions with as much detail as possible.

XCC-System and System Models:

      The system I noticed was the system connection between the periodic table, elements, ions, cations, and anions. The system is that all the elements have a place on the periodic table and that all ions are elements but not all elements are ions. All cations are ions but not all ions are cations, and all anions are ions but not all ions are anions. That is how the system works and it works perfectly. It allows things to be categorized much easier kind of like how the periodic table defines each element by how many protons it has. This is a great system that allows all elements to have a place.

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 ...

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

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...
