Standard 8 self-analysis 2nd quarter

Remembering what I did in chemistry:

1. Worksheets
2. Elements and Such
3. Conductivity Lab
4. Into to Ionic bonding and Ionic Compound Formulas
5. Magnesium Lab
6. Covalent Bonds
7. Types of Reaction

What is important about it:

Each blog I wrote was very interesting and fun. The class was just engaging to be in. I enjoyed learning about the elements, the magnesium lab and the types of reaction lab. The blogs and book work gave me more knowledge of Chemistry.

Applying:

The only reason I apply chemistry to life everyday is because I have it 1st hour. I guess I could use chemistry everyday somehow.

Evaluating:
This 2nd quarter has gone by fast but I think I did my best. My blogs were really interesting, in-depth, and detailed. Most has really good references and youtube videos that enhanced the blog and my showed my knowledge of the subject I'm talking about. So I would give myself an A for effort.

Creating:
Form the 1st quarter I think I reached my goal of putting more visual effects into my blog and using more technology in the class. I also have reached my goal if having deeper explanations of what we were studying. This next quarter I would like to get better and writing blogs and getting more 4's. For this next quarter my goal is to get all 4's. 

Types of Reactions

With this blog post we did 7 different reactions and named they formula that went with them. We did a slide show and added some videos of the coolest labs. Also the blog shows the type of reaction and an explanation of what happened in the lab.

Covalent Bonds

Recently we have been studying about Covalent Bonds and what happens when they do bond. Also we have talked about the Lewis Structure, molecular shapes also known as the  VESPAR model which is an acronym for Valence Shell Electron-Pair Repulsion. We have done many different worksheets and and bookwork. We have looked at equations to find out if they are ionic, covalent, or both. How you find out these types of is you look at the equation and see if its a metal+nonmetal and it would be ionic. If you have a nonmetal+nonmetal it would be covalent and the last way would be a compound containing a polyatomic ion. An example of an ionic compound is CaCl2 because it is a metal+ a nonmetal. H2O is covalent because it is a nonmetal + a nonmetal. Lastly Na2Co3 because it contains one polyatomic ion. Going back to the Lewis Structure, molecular shapes and VESPAR model. The Lewis Structure is a dot diagrams is the amount of valence electrons in an atom. This video is a really good explanation on how to write them.



After you understand the Lewis Dot structures you move into the VESPAR model or molecular shapes
the formula CH4 has a Lewis Structure is this image here----------------->

This video is a really good tutorial about the VESPAR model.






The molecular shape of CH4 if a tetrahedral because it has 4 total pairs and 4 shared pairs and 0 lone pairs. This video explains a little more about how the molecules combine and form these 3-D shapes.

Here is a worksheet I did about Lewis Structure and the Molecular shapes it has.

Here is the back page of the worksheet.
