November Reflection

I think of myself as an efficient mathematician. I can persevere through a problem. Even if it is very challenging, I will take a risk and go for it. Sometimes, if I don't know what the problem is or I don't understand it, then I move on to the next problem and come back to it later. There is one area in math though that I really struggle and I don't really understand. Circumference, pi, and diameter. For me it’s kind of challenging because I don't understand the way I would have to figure out the diameter if I know what the circumference is. The formula of Pi x Diameter = Circumference or something like that is really confusing for me.

Some habits of good thinking I have are  that I persevere and am able to estimate a problem if it consists of very large numbers. Also, I reread the problem and put it in my own words so that I can understand it better. I first didn't understand what GCF &/or LCM was for, though when Ms. J explained when we use it, I could understand it better. I practiced at home and I feel way more confident in doing an LCM &/or GCF problem now because I kept on practicing.
I feel like I think very strategically when I’m thinking mathematically. I think of an answer the way I would think of it as a “battle”. I figure out the correct method to complete the problem.

I think that to be a “good” mathematician, you have to persevere in solving a problem. You can't just give-up and not do anything, you have to try, try, and try again. Using a different method each time to see which ones make the most sense. You would have to make sense of a problem and be able to put it in your own words and think, “Oh, so that’s how you solve it.” Or you should be thinking, “Hmm. I see that this method doesn't work. But wait a minute, this is finding the common frequency of events. So it’s LCM.”

SUTTS Final Reflection

When I first went to SUTTS, I thought I wouldn't really have much fun because I already felt comfortable talking in-front of a stage, though after this quarter, I see that there is waaay more to talking in-front of an audience than just standing there and talking.

Something that was really awesome during this quarter is that we got to collaborate with different people and present a couple of different projects
Something that I'm going to take away from SUTTS, is presentation details. The delivery, the actual slides of the presentation, and talking in-front of the audience. The specific tips for those things.
Something that could have been better in this quarter is that I would have like to finish the "play-type-of-thing" that we wrote. I would have liked to close that up better.

Overall this class was really fun. I highly recommend that you take this class!

Down below are some questions and answers to my informative speech, and presenting in general. Here is the LINK to my presentation.

1)  What are the qualities of creating a strong presentation?  (Content and Preparation)
  • Be Prepared
  • Visuals
  • Project your voice
  • Volume, Tone, Pace, Dynamics
  • Body Language: Be engaging
  • Don’t look at the board, look at the audience
  • Cite your sources

2)  What are the qualities of delivering a strong presentation?  (Delivery)
  • It has to be engaging
  • Make sure the audience likes what you’re talking about

3)  What did you feel was one strength of your informative speech?
My visuals and the amount of text on one page

4)  What was one area you feel you still could improve upon?
I think I could improve upon time limits. I did it in 3 minutes, though it was supposed to be between 5-7 minutes. I should have practiced a bit more with a timer!

5)  What would you do differently the next time you have to present before an audience?
I would practice more, in-front of my mom, brothers, sister, and practice with a timer and see if my siblings and/or parents actually like the presentation. I could ask them for feedback and stuff.

Matter Does Matter ~ Final Reflection

During this quarter we learned all about Matter and it's Buikding Blocks. I learned a LOT of different things. Things like the formulas for specific types of atoms. I learned about molecules, What a compound and element atom is, the difference between an atom and a molecule. How molecules move in a specific phase of matter, and more. 
Above is a video that Claudia Nanez, Tashi Guarda, and I made for science. We answered some questions related to experiments we'd done in class. One experiment was with methylene blue, we put one drop into a beaker with water, and waited 4 days, then gathered out results. The second experiment is when we blew up a balloon, then we measured the circumference of it's widest peak. Next we kept it in a box for 4 days, then came back to it and measured the circumference again on the same spot, and recorded our results. 

Here is my KWHLAQ chart:

What did I know about matter? =

The stuff inside your body

•Matter makes something something
•It gives weight or mass to something

What Do I want to know? =

•Are different types and/or amounts more dangerous than others?
•I want to know more about John Dalton

How will I find out? =

•Scientists= the news
•Talking to People

What have I learned? =

•Matter has atoms and molecules
•Atoms were discovered by Democritus, but then rediscovered by John D. in the 1800’s
•If you do an experiment, where you add 1 drop of methylene blue i n to water, and leave it there for 4 days, it will look like:
  • Methylene Blue: Spread out in the beaker, so not all packed in one place.
•The difference between Mass and Weight is that mass is the stuff inside something and weight is the pull of gravity on an object.
•The greenhouse effect is "the warming up of the earth" from certain gasses
•Those certain gasses are: methane, carbon dioxide and nitrous oxide
•In a greenhouse, when sun rays shine on a greenhouse, it goes through the glass in the greenhouse. The hot air gets trapped inside and so makes a warm air for plants, animals and humans inside the greenhouse. It's the same as our planet, which gets warmed up by the sun, and so creates a nice warm air for us to live in. The greenhouse gasses help with this. If we didn't have these gasses, the world would be -33ยบ celcius; so way to cold for us to live in. If the greenhouse effect gets too out of hand, then the earth could warm up and it could influence weather, and it could cause problems to the environment. Scientists have researched more in this and are finding that it is already starting to happen, this is what they call global warming.
•The main cause of global warming, are the greenhouse gasses. The effect it is having on our planet now is not so good. Especially the carbon dioxide and the methane gasses.
•It is mostly caused by humans, for example: burning fossil fuels=more and more carbon dioxide an deforestation and forest fires is bad because plants and trees give oxygen and take in carbon dioxide gasses.

How will I take action? = 

•I'm going to try to reduce the amount of greenhouse gasses that goes into the air by:
•Reduce, reuse, and recycling
•Use less air conditioning and heaters
•Plant a tree! I've always wanted to do that! :)
•Turn off the hot water when I'm not using it
•Turn of the lights, since they give heat

What questions do I have? = 

•Are different types and/or amounts more dangerous than others?
•Is planet earth, matter?
•How did democritus come to the idea that atoms existed?

Slime in Science!

On December 2nd, Monday 2013, we did a super cool slime experiment in Science! We used 4% Borax and 50% Glue and food coloring to make our own slimes! We took the slimes we made home and now we can play with them and stuff!

Borax = Looks like water, runny, transparent, liquid
Glue = White, liquid, sticky

Polymers: A polymer is a substance that is made up of a long chain of molecules from the same sort.

Some examples of Polymers from my house:
Water bottle
Flip Flops
Plastic mini-basket


Claudia and I worked together on the slime project, and we worked really well together to achieve the making of a good slime!

Recipe 1: 1 tbsp Glue + 3 tbsp Borax
This recipe was too liquidy, so we added 4 more extra tbsp of Glue

Recipe 2: 2 tbsp Glue + 2 tbsp Borax
This recipe was to gloppy, but still very loose, so we added 8 more tbsp of glue

Recipe 3: 3 tbsp Glue + 1 tbsp Borax
This recipe was too sticky. To correct it, we added 2 tbsp of Glue

CORRECT RECIPE = Recipe 4: 5 tbsp Glue + 1 tbsp Borax
The perfect Slime, it was sticky, gloppy, and still great! This one turned out awesomely!
