Science- Chemical Reactivity Reflection


A. What are 3 things you learned in this unit?
The three things I have learned in this unit are the different type of bonds, alkali metal,alkaline earth metals, noble gases, halogens and how to balance chemical equations.Firstly, I learnt about covalent and ionic bonds and what is the difference between them. A covalent bonds is when to atoms share electrons to fill there outer shell, giving them the maximum amount of valence electrons. An ionic bond is when one atom steals an electron giving them both a charge, the atom that took the electron will be negative, and the atom that just lost an electron will be positive, however this will only happen in the atoms are stable. Secondly I learnt about alkali metals, alkaline earth metals,, noble gases and halogens. These are different  classifications of elements on the periodic table. Finally, I learnt about chemical equation. Chemical equations are used during a chemical reaction to balance out chemicals due to the law of conservation of mass. 



B. Which of these 3 is something you will likely never forget?
I will probably never forget the difference between ionic and covalent bonds. I will remember this because I studied this very hard  about the different types of bonds and why they are special.



C. What is your favorite thing we did in this unit? Why?
My favorite part of this unit was doing the experiments with different chemicals. Firstly, this was interesting finding out about what happens when different chemicals are combined. Secondly, this was also a learning excersise, because it taught us about the difference between a chemical change and a physical change. 



D. What is something related to what we studied that you are still curious about?
I concept that I am still a little curios about is chemical and physical changes. Although we did the experiments which really helped, I still do not understand how to identify between the two. This was probably the only thing that I am curious about and I would like to understand what they are a little more.

English Class So Far.....

So far in english I have learnt many things. Firstly, that when you are free writing, you first have to get everything out on the page. This is a way to let your ideas flow and not be critical about your writing. Secondly, you then go through your writing piece, taking out parts that dont work, then the parts that do add to them. For example, Mr. Raisdana had a good metaphor. He compared free writing to gold mining, and how you sift through the bucket looking for pieces of gold.
What I really enjoy about this class is the round the table discussions. I find that these discussions, are a really great way to share ideas and get your thoughts out. The discussions, also make us a better class all-around, because the more discussions we have the more confortable people are becoming. I also really enjoy the idea of having a blog. I have never had a blog before and I think that it will be a interesting process of sharing ideas.
The only suggestion I have for the class is that we do more sharing of our pieces. This could be  around the table, and someone reading out there piece and we could all comment (in a positive way) and make suggestion(nicely).
