Week 2 April 17 Week 3 April 23
 * 1) This week during science class I learned that the valence shell is the outer shell and the electron shells are the shells that are inside the valence shell, this stuck in my head because it confused me really bad at first, and I previously thought that the valence shells were all the shells not just the outter shell, also making the examples of atoms helped me to finally pick up on this.
 * 2) Another thing I learned this week was that some chemicals such as carbon which is not a metal it is a non-metal and so when you smash them they fall apart because they are brittle, unlike lead that is malleable and just squishes, during the experiment yesterday I learned this, another metal was zinc, this one was fun to smash because it was brittle so it splattered all over.
 * 3) Something that interests me and makes me want to know more about is the reactions with different chemicals; I like to see the reactions. I also love doing experiments, they make science class more entertaining and helps me to learn, something that would be awesome to see is sodium and magnesium because they were the two that seemed to be the most active. We never expirmented with sodium but Mr. Burtis showed us the crazy reaction in front of the class.
 * 1) This week during science class I learned that baking soda and vinigar have a reaction, we did three different trials seeing the difference in weight and I learned that if the gass does not escape then the mass will stay the same and that if the gas evaporates because it is open and the mass will lessen, although when we did trial 2 the mass stayed the same because of the cap was put on before the reaction started so that the gas will not escape.
 * 2) Something else that I learned in science this week is the balancing of equations. The Conservation of Matter Law which states that both sides of the equation have to be equal. If there are two hydorgens on one side you have to make its so there is two on the other side. Then using the multiplication it makes it easy to do this. Plus every element in the periodic table uses this law when in equation.
 * 3) I learn better when I learn hands on stuff, so when we do labs I very much enjoy it and something I would like to learn more about is fire and reactions it has to different chemicals and gasses, it would be interesting to test it with solid sodium because last week we learned that sodium is very reactive and it sits in caroseen so that it won't react with the air or oxygen, also fire is scary and awesome so it would be a perfect combination.
