Math Revision Blog Post

*(@^<>^@)*       @<(!)>@        #(:<^-^>:)#       (^&-^^-&^)

(PS: That’s the introduction by the way 🙂 )

So, back to business, our current topic is Measurement & Probability.

For measurements, to calculate a triangle’s area, you just times the length with the hight then divide them by two. Like this : length x hight / 2 = Area. Also 1m=100cm, 1cm=10mm; 1000m= 1km.

For probability,

There are 5 main words in probability, they are:

  1. Impossible – it will NEVER happen.

  2. Unlikely –  not likely to happen.

  3. Even chance – 50% chance of accuring.

  4. Likely –  quite likely to occur.

  5. Certain – Will occur or happen.

Now, question time.

Measurements: Q1, Area of this triangle: H- 13 L- 21; Q2, 1243m= ( )mm;

Probability: Q1, Tickets numbered 1 to 20 are mixed up and then a ticket is drawn at random. What is the probability that the ticket drawn has a number which is a multiple of 3 or 5?  Q2, A bag contains 2 red, 3 green and 2 blue balls. Two balls are drawn at random. What is the probability that none of the balls drawn is blue?

I enjoyed doing the probability unit the most. Because in measurement unit we need to calculate a lot I’m not really good at.

Tech Tutorial —- How to use chopsticks

Hello guys, this is my tutorial that teaches you how to use chopsticks. I have been working on the in technology class for this tutorial unit. The reason why I chose to teach how to use chopsticks is that I figure that if you’re a European or Americans (Not being racist here! ) who dose not know how to use a chopsticks and you went to visit Japan, and you’re eating at a local restaurant which serves only chopsticks. Then you are going to face a big problem, that there’s very delicious foods right in front of you but you have no idea how to use chopsticks to eat them. But after watching my tutorial, you should be able to do that. Hope you guys like it.

CONNECT

During the process of creating my tutorial and the finished project, I think those things meet most of the tutorial criteria that our class made. First, I spoke clearly and loudly and the language is easy for people to understand. Second, my video doesn’t have any weird background, it’s just a white wall, with no noises except for me speaking. Also, I gave some titles in the tutorial for keynotes, like when you’re using a chopstick, make sure that you’re using your dominant hand. And since I filmed my video with my laptop, so it the camera was very steady, and the quality was quite good. Also, I gave some tips and tricks in the video. For example, when you’re holding chopsticks, not too far in the front, not too far at the back. In addition, in my video, I always stay on the topic and the background music is pretty cool but not destructing the viewers as well. And I also gave credits and the needed materials too.

Extend

During the time when I was creating my tutorial, I got some inspiration from other tutorials and peoples. For example, the idea of the intro in my video, just music without any voice but also can introduce your video is from this video. The idea of zooming some part to show the details of my tutorial is from this video. Also I think it’s very important that a tutorial has a interesting and useful thing to teach, so that it can “hook” the viewers. The idea of teaching how to use chopstick is from a friend named Charlie, he’s from America so he don’t how to use chopstick, and one day saw him struggle with using chopsticks to eat cup noodles from a convenient store, and that inspirited me. In addition, I learnt a lot about Imovie editing. For example,  how to add music; how to duck soundtracks and volumes of the music and how to add transitions and titles.

Challenge

I think there’s still some challenging things for me and questions that puzzles me. For example, what music should I choose for the video, because if you’re trying to teach something, it’s probably not good to have rock music in the background. Also, I think I have the basic editing skills in Imovie, but to make a better tutorial, I think I still needs to learn more advanced editing techniques.

Analyze

Last week we also looked at people’s tutorials from other class to analyze them by commenting on their tutorials. Here’s some examples that I commented on.

Kai’s tutorial

William’s tutorial

Alex’s tutorial 

Also, in the very beginning of this unit, we created a survey for later (which is now) to evaluate our tutorials. Feel free to fill it in. Thank you. BYE. 🙂

My Artist Statement

This unit in art we’ve been working on paint self- portraits for a long time and I’m nearly done. This is my painting.

Photo on 4-16-14 at 1.02 PM

The title of my portrait is “I’m (not) alright.” The function of this painting is social.

In the very beginning of this unit, I first start with practicing blending colors to make tints and shade. For example, from  light blue to dark blue.

Photo on 4-16-14 at 1.55 PM

 

Then I practiced blending different color into each other so that they don’t have those hard lines between them. After that, I made a portrait painting planning checklist. That’s for helping me think figure out what do I want my portrait is about, what’s the function of my portrait, what does is represent and what will it look like. Then I looked at lots of artists’s portrait for inspiration and ideas for our own painting. Next I drew two different composition sketches like how big do I want the head be and where? I also did a quick sketches of the portrait just to practice and think about the colors. After that we  just kept drawing and trying out new brush works and color blending.

During that process, I’ve ran into lots of problems and challenges, but I have overcomes them all. First thing is I not good at drawing so the outline won’t be so good, but I practiced once at home so I knew what i’m going to draw. Second, I couldn’t control my hand to be very steady very well so some times my brush shook a little bit then the line wasn’t straight, or the color when over the place where it suppose to be. I solved this problem by picking very very thin brushes to paint some parts. Also, another problem is that when I try to blend colors to it’s tints and shades, next class I came but I forgot how much white or black I added last to blend the same color. So every time I will paint the color on another piece of paper to see if it’s the same color as last time. In addition, when I try to blend to colors together to make a gradation, the old color always get dried up and make it hard to blend. I solved it by wetting the brush just little bit and wet the color again before blending.

I think my painting has lot of strength. For example, I think it’s really cool that half of her face is in shades color, and the other half is in tints color, and half is smiling and half is crying, also with some good blending between those tints and shades. Also, I think the hair looks realistic because I used different values of tint purple, different values of dark purple on both half of the face. Also what I think I did really good is the background sky, I spent a lot of time to blend the tint blue and the shades blue. It also took my some time to blend them together, from light to dark.

My drawing not only has strength, but some weaknesses as well. For example, I think I could have paint the tears more realistic. Also, if you look closely at my painting, there a lot of little white dots on it. That’s because as I mentioned before, my hand isn’t steady, I’m a faired of draw the paint over other colors so I’m not going to fix it.

I show my cousin’s personalities and how she’s like in this painting. For example, like what I just mentioned before, I painted her face half dark purple, and half light purple because that shows that when people teases or make fun of her, she will pretend to smile but she actually felt bad and sad. Also you might notice that I didn’t paint the background like her face, instead I painted it both half the same for a reason. That’s because her personality don’t effect the “outside” or other people so I didn’t paint it one half tints and the other half shades. And most of the times her personality is hidden.

Civilization

Civilization is a living society that s made by a group people. There are three main things about civilizations, they are 1. Economy: money, trades; 2. Culture: religions, clothing, food and music; 3. Government: People that are in charge of the civilization.

In this unit of Humanities, we’ve been working on a project called the long lost civilization. We basically just make our own national geographic of the made- up civilization which is made by our- self. Click on the link to check it out.

I’m proud of that because I think I wrote a lot of details about the discovery of the civilization that I made. And I think it looks like a national geographic. Also I think it was really creative and good looking.

From this project, I’ve learnt a lot of thing. For example, what makes a civilization, what’s a civilization’s characteristics. In addition, how to make a national geographic and a magazine.

How to separate salt & sand mixture

Materials:

1. Water.

 2. 1 Bunsen Burner                            

3. 1 Heating Mat

4. 1 Tripod

5. 1 300ml sized Beaker

6. Matches

7. Safety glasses

8. Gauze mat.

9. Glass rod.

1o. Funnel

11. Filter paper

12. Retord stand.

13. Ring.

Method:

1. Add the water into the beaker with the sand and salt mixture, until the level of the water reaches 300ml.

2. Set up the bunsen burner as the picture below, and start heating your mixtures. Don’t forget to wear your safety glasses while heating the mixture.

3. Use the glass rod to mix your mixture and to get the salt dissolved. Remember to take the beaker of the bunsen before mixing it.

4. If the salt is completely dissolved stop heating. Keep the bunsen burner, you will use it later on.

5. Set up the filtering system like so in diagram below.

6.Start pouring the mixture into the filtering paper : little by little
(TIP: change your filter paper if it becomes soaking wet. Keep the sand though!)

Check point:

So far if you’re doing correctly, the sand will stay on filter paper while the salt water is now flowing into the other beaker.

7. Wait until the beaker had cooled down, then start heating the beaker with the salt- water once again.

8. Wait for all the water had evaporated. (That might take a wile but be patient.)

Final Check Point:

And now if you have done it correct, you have only the salt left over in the beaker.
