Today as I was working with my touchpad I realized that it felt slicker, than it had before. I had just gotten a replacement a few weeks past so it feeled a little airy and sensitive, and a little bit rough in a way, but now it felt somewhat smooth, and I had to sort of press down to move the mouse around. I guessed that this had to do with friction. Friction is a force that appears when two opposite surfaces rub each other. In friction, although the two surfaces may be smooth they are very rough and jagged causing them to drag and grind against each other. This makes sense because my finger and the touchpad are two different types of surfaces.

Friday, May 14th 2010~Roots
I spent some of my time today after school gardening with my mom. Although I really loathe doing this chore and sometimes I don't. When I don't loathe this chore, is usually when I let my evil side get the best of me, and I hack off branches or a whole bush (depends), but I do hate pulling weeds, but then I use the hacker and go Ka-Pow, Pow, and yeah. Anyways, when I pull the weeds after hacking I have to grab the roots and sift the dirt out of them. But then, I stared and the roots for a little while and thought what are these roots? Besides holding the plant up what does this part do? Well, I googled it and found that roots are constantly bringing the plant minerals and water, it's like the umbilical chord for the baby (Sorry, Health) anyways...yeah. This is related to science because plants is botany which is a fancy word for saying the science of plants.

Wednesday, May 6th 2010~Mucus
I was sick today, and had to go to the doctors because my ears really truly hurted. So I went, and my doctor said that me ears hurt because the fluid from my mouth or mucus spread to my ears because I refused to take it out (I still do!!). So why is mucus created? Mucus has to do with the respiratory system and is basically a thick liquid produced by the lining of tissues in our body. When we get sick it creates this liquid and it gets stuck in our throat and makes us cough. How is this related to science, you ask? Well, the respiratory system is a part of biology which is the science of humans/living things. So in case you didn't know MEDICAL/DOCTORS ARE SCIENCE!! Bye!! :)

Tuesday, April 27th 2010~Swimming
Today I finally touched the bottom of the twelve foot deep pool, and I have to admit it was sort of scary. At first when I tried touching the bottom, the pressure in my ears got too big. On top of that I felt lighter in water than I did in real life, which made me feel like I was drowning. This made me have some questions like why does the pressure build up the deeper I go down? Why am I lighter in water? What is it called when you're afraid of drowning? Why do we become afraid? To figure out the answer to these questions I went to my favorite search engine: google.com. The pressure in the water builds up as we go deeper down because what we're actually doing is removing some air from the space inside and above the water, so that the air pressure drops below atmospheric pressure. Why am I lighter in water? I'm lighter in water because of I have a lighter density than the pool. Density is defined as "the mass per unit volume" Density has something to do with buoyancy. The fear of drowning is called Aquaphobia and I have that fear because I have an emotional response to a percieved threat. Meaning whenever I feel like something is going to hurt me my body makes an immediate response to leave or whatever is appropriate in that situation.

Monday, April 19th 2010~Homemade Tuning Fork
As usual my little brother goes out to play outside, usually with a friend, but today he retired and stayed home. One thing you have to know, in order for this to make sense, is that we have one of those "playgrounds" outside our backyard. Ok, back on track, my brother took this handle from a sand toys bucket, and bangs it on the this wheel. The wheel vibrates, and for those orchestra players, it sounds like a B# (high 4th finger on the E string). Yeah, it was annoying. I thought it was neat that my brother made that without even knowing what he was doing. What's even cooler is that when my little brother moved the handle closer, the pitch went higher, when he moved the handle farther away, the pitch went lower. I thought it was neat, but after a while I sort of got annoyed with the sound and told my brother to cut it out. ;)

Thursday, April 15th 2010~Static Electricity
I was trying to teach my little brother what static electricity. I tried demonstrating to him, I blew a balloon up and rubbed it against the inside of his jacket, and showed him that if you do that static electricity makes your hair stand up. At first, he gives me a confused look, so I demonstrated to him again, twice. Two minutes later he was showing what I showed him to my dad, and then he just gives me his mischievious smile...URGH!! Yay for statickey hair!! :)

Wednesday, April 7th 2010~Eyes
I had to get an eye test, well because my vision isn't totally perfect. I had to take a lot of tests to determine what was wrong with my eyes, or in this case, eye. Turns out one of my eyes (my left eye to be exact) is nearsighted, meaning I can only see near. Bad, Huh?? Anyways, I'm nearsighted on one eye, because my pupil on the left eye, instead of being round like a basketball, is shaped like a football. To basically see, how "deep" it is, she dialated my eye. Basically putting chemicals in my eye, to make my pupil look bigger. For this to happen it took 10 to 15 minutes. During this time, my grandpa was taking his eye exam. His glasses, due to his age, are bifocals. Bifocals are for people who are farsightedness. When this happens, they have a small "square" or "window" as I call it, in which its like a magnifying glass. When my eyes were completely dialated, she took a picture of the back of my eyes. I saw my optic nerve (which was red and thin) and I saw my veins (which are red, and look like branches on a tree). On top of this I saw a part I haven't heard about called the macula. The macula is a tiny area in the retina which lets us see, and is responsible for letting our vision see straight. There is disease called the macular disease which if you have it, instead of seeing perfectly, you have black splotches in your eyes, so you have to see on the side of your eye. My grandpa got his pictures too, he had the same looking picture as me, however because he has diabetes his eye is bleeding, and if it bleeds too much, it'll cause him to go blind. Great adventure for today!! ;)

Thursday, April 1st 2010~Dynamic Inertia
I saw another add on how women can loose the flab in their arms. It was showing this mechanism, which required only human-power, and when you shook it, it worked your arm muscles. It then said, that this is based on dynamic inertia. Knowing what inertia is from Newton's first law, I guessed that it was about that law which states that an object in motion will stay at motion, unless an unbalanced force acts upon it, and an object at rest will stay at rest unless an unbalanced force reacts upon it. This made sense to this add because in this case, when the person stopped moving the device, the device stopped too, same thing when it was moving. But what does dynamic have anything to do with it? I went to dictionary.com and the definition that most made sense was "a basic or dynamic force, esp. one that motivates, affects development or stability, etc." In here they were affecting the flab of the arms. This made so much sense!! XD

Tuesday, March 23rd 2010~Inclined Plane:Ramps
I was walking from East Hill, to my mom's car, and to cross a street they had this "thing" (I don't know what you call it) in where you could go walk in the middle of the road, without having any cars stop for you. Confused? Let me explain. Basically you walked from the sidewalk up two inclined planes, where you ended up on a flat "bridge", you then walked down two inclined planes where you ended up on the other side on the sidewalk. When I was doing this, I couldn't help saying "I'm walking on an inclined plane." So that's my connection. Bye!! :P

Thursday, March 18th 2010~Magnets
I have these magnetic earrings, so what I do is that I snap one earring on the front of my ear and on the back a small magnet that holds it!! I asked Ms. Piehl what's the concept behind them? Why do they stick to my earlobe?? According to her, the magnet is strong enough to emit a magnetic field which is strong enought to stick to the other magnet in the earring. Sorry for me, though, IT HURTS MY EARS!! :)

Friday March 12th, 2010~Vibrations
When we were at our Orchestra Field Trip, this ed-juticator(I seriously don't know how to spell) talked about that when we run the bow across, our violin string vibrates, creating a sound. The pitch changes when a string is stretched too tight, or it is stretched too loose. The thickness of the string also affects the pitch. I guess, I never thought of it that way but this is how a string instrument works.

Tuesday March 9th, 2010~Radiation Therapy
Cancer is talked about everywhere, in books, movies, talk shows, it's a main cause of death, but when I came across in a book the type of therapy's a cancer patient had to go through, I was kinda surprised. They talked about Chemo Therapy (which seems like the most common therapy), this other one and Radiation Therapy. Knowing what Radiation is, I thought does Energy have anything to do with this? So I Dictionary-ed it, and check this out.... Radiation is the treatment of disease by means of x-rays or of radioactive substances. Radioactive, for those who don't know, is basically (that's my favorite word =D) an object emitting radiation, and the nuclei atoms change making it magnetic. So these are like two things we learned:
1) Radiation Energy
2)Elements
Pretty cool, in my opinion....

Tuesday, March 2nd 2010~Chemical Changes
I love soda. I have tried coke in milk, and to me and my family that is the best drink ever, so I was really surprised when I mixed Fanta with milk, the milk curdled. It was fun to watch the chemical change and physical change of something in real life, but I have to admit, I was forced to drink that milk. It didn't taste bad but it felt weird, having half the milk stick to the glass. Try it sometime but don't drink it!! :)

Friday, February 27th 2010~Piezoelectric Property of Crystals
When I was researching Quartz Clocks as a chain for the Humanities Inventions Project, I found that the Quartz Clock relys on the Piezoelectric Property which states that if you apply an electric force to a crystal it will change its shape. However, if you squeeze it or bend it it generates it's own electric field. I will so try that as an experiment...Someday!~but for now I thought that was neat!!

Tuesday, February 23rd, 2010~Flowers
Yesterday when we were done with School of the Future Presentation in front of the architects. When we were done we stopped by a lake-front park to eat. There was a cherry blossom tree that was blooming. Ms. Piehl showed us the female and male part of the flower. The tall part in the middle of the pollen is the female, and the male is the pollen. They mate when an unbalanced force takes the pollen and touches the pollen. For example, a bee usually does this job.

Friday, February 5th, 2010~Science in Reading
I was reading Alex Rider:The Gadgets, and most of the gadgets they talked about were related to science. Some of the topics they covered were about chemicals, microfibers, gears, and so much more. Since I'm not very good at science I didn't understand most of it. (It was written in high sophisticated "dictionary" terms.) Yet they did have a Glossary which helped. Who knew science was in reading?

Friday, January 29. 2010~Food Processing
Well, on Friday I was eating dry fruit, and I noticed that there was two types of dry fruit. One was crunchy, and sweeter, and looked like the real thing. The other however was hard to tell, yet the flavor was stronger, compared this one was dried like a raisin. I asked my mom why...she said she didn't know. So today, because today was the only day I was free, I went on google and typed dried fruit. I went to wikipedia (although I know it's not a source, but a follow-up), and it said some dry fruit had sulfur oxide, which made me relate back to the adopt an element project. My element was Sulfur, and the cool thing is that sulfur oxide, is sulfur added to hydrogen...which I thought was neat. I didn't get the answer I was looking for, but it made me relate back to science.

Wednesday, January 20, 2010~Genetic Testing
Ok, I just watched Dr. Phil like right now, and they were talking about the "Trends for 2010: The Good, The Bad, and The Ugly. " One of the last trends they talked about was Genetic Testing. They're saying that technology can help us discover if we are likely to have a disease in the near future, diagnose a disease, and if your children are at risk. How? Ok, lets start from DNA. Our DNA (Deoxyribonucleic Acid) is made up of chromosomes and determine our genetic makeup (I don't know if this is the best way to explain it.). What genetic testing does is that it detects "gene variants associating with a specific disease or condition." This technically means that if there is something different in our genes, and is that difference related to a specific disease or condition. This is a controversial topic because that information, if slipped out, could be used against that person. That's why there's this organization called GINA which stands for Genetic Information Nondiscrimination Act. So, apparently that's a Trend for 2010!!
A few days ago I was watching this show with my mom called The Emotional Life, on KCTS. It was talking about depression, and what happens to the brain when depression takes its toll. It was explaining that depression happens when serotonin (a chemical in the brain) is imbalanced There were a lot of treatments, that dealt with the different types of depression, such as major depression or clinical depression. When taken the chemicals in the medicine work to make the chemical balanced, yet with some side affects!!

Tuesday, January 5, 2010~Simple Machines-Lever
Yesterday my dad was sitting on the couch, and I really needed him to stand up and find me some scissors so I could work on a project. Of course at first he didn't move, but then I had an idea. To make him prop up by taking his arm, putting it in an arm wrestling position, and pushing down on it. It worked!! He propped right up!! I don't know if this actually is an example of a Simple Machine, because I didn't make anything, or used any type of material to use as a helpful force (like a wood block, or something like that), I just used his arm. But it made me thinking like a lot of our body parts are like simple machines. Or could be used as one!! =D

Thursday, December 17, 2009 ~Newton's First Law-Forces-Matter
On Sunday, my little brother was super happy that he had pulled out a big block of ice by himself. Apparently, a dishwashing soap bucket had been left outside, and because of the rain, filled the bucket. Then on Saturday, when the night was really chilly, it turned into ice. I couldn't help remembering when we had learned about Science, and matter, and that if you deduct heat from water it turns to ice, and that the atoms go slower. Then a few days ago, I think on Tuesday the big ice cube started to melt. I can't really tell if it's out there or not.
When we were playing Soccer in P.E., my eyes focused on the ball, and I couldn't help noticing the force of someone's foot kicking it. When we kicked it hard, it went flying, and went far. But, when we hit it lightly the ball barely moved. When I was playing goalie, Newton's first law of Inertia came into play. When someone kicked it, and the force of my hand (or foot) didn't stop it, then it kept on going until it bumped into the fence. -Rania
Today as I was working with my touchpad I realized that it felt slicker, than it had before. I had just gotten a replacement a few weeks past so it feeled a little airy and sensitive, and a little bit rough in a way, but now it felt somewhat smooth, and I had to sort of press down to move the mouse around. I guessed that this had to do with friction. Friction is a force that appears when two opposite surfaces rub each other.

Apparently, a dishwashing soap bucket had been left outside, and because of the rain, filled the bucket. Then on Saturday, when the night was really chilly, it turned into ice. I couldn't help remembering when we had learned about Science, and matter, and that if you deduct heat from water it turns to ice, and that the atoms go slower. Then a few days ago, I think on Tuesday the big ice cube started to melt. I can't really tell if it's out there or not.
When we were playing Soccer in P.E., my eyes focused on the ball, and I couldn't help noticing the force of someone's foot kicking it. When we kicked it hard, it went flying, and went far. But, when we hit it lightly the ball barely moved. When I was playing goalie, Newton's first law of Inertia came into play. When someone kicked it, and the force of my hand (or foot) didn't stop it, then it kept on going until it bumped into the fence.
