How can pets make you happy?

    A pet is good for your heart High levels of cholesterol and triglycerides can up your risk of heart disease, but owning a cat or dog can lower both, according to the Centers for Disease Control and Prevention (CDC). Owning a cat or dog can also increase your chances of surviving a heart attack. Pets lower stress and […]

First Day in a Foreign School

*These are some of my opinions and comments and I am not insulting anything/anyone School Website: http://www.nhcs.net/noble/ This is the first American school that I’ve been in and I would like to tell my experience to others. I hope you are looking forward to this and I tried to take pictures but it’s hard because there is a rule that you cannot take pictures. This is Noble Middle School, one of the public schools in Wilmington North Calorina. This school has a very strict policy about bullying, inappropriate content, and profanity. And the school mascot is an eagle. I got into the school in the middle of the semester which is bad because everyone has friends except me. But don’t worry, I’m used to it. At least, I made a couple of friends over there. I was struggling so much on my first day. It was such a horrible nightmare. I was so scared that I had to ask the school counselor so many questions so many times. The system is very different from Thailand obviously because Thailand schools had no lockers and you do not need to change classes most of the time. Many of my classmates were afraid to talk to me because they do not know who I am and they didn’t even realize I could speak English. One thing that I remembered is a group of 4 girls gave me a salad in a cup, which […]

Paper or Digital?

I rather use paper because I feel much more comfortable and it is easier for me read and some students can process the content better. But some kids are more comfortable with screens. E-readers appeal by being travel-friendly and storing a whole library at your fingertips, but print books seem to win when it comes to comprehension. Studies have shown that readers often remember more when they consume material in print rather than from a digital source. This is most likely linked to the concept of spatial context, which causes “seemingly irrelevant factors like remembering whether you read something at the top or the bottom of page—or whether it was on the right or left hand side of a two-page spread or near a graphic—can help cement material in mind.” According to the market research firm Millward Brown, “tangible materials leave a deeper footprint in the brain.” The physical and sequential task of writing letters and words creates a stronger connection with working memory than tapping on a keyboard. The physical representation of written plans and tasks is then perceived as more “real,” which makes them easier to remember. Here are tricks to writing a more productive to-do list. A UCLA study has shown that manually writing notes with a pen and paper is more conducive to retaining information than typing notes on a laptop or computer. This is because “analog” note takers—those who used a pen and paper—were forced […]

Are boys actually better in math?

In preschool and elementary school boys and girls generally perform similarly on math tests. Later in school, in high school and college, more consistent differences start to emerge. In addition, gender differences are often larger among higher-performing students but not necessarily for lower- or average-performing ones. Within this specific group of higher-performing math students, boys tend to perform better. Similarly, when studies do find gender differences among elementary school children, they find these start to appear for higher-performing students earlier in schooling than they do for lower- and average-performing ones. Whether a gender difference is found also depends on what type of math the kids are doing. In general, boys tend to outperform girls on tests that are less related to what is taught in schools (like the SAT math test, for example) whereas there tend to be minimal gender differences on statewide standards-based math tests, which are more tied to what’s taught in schools. When it comes to grades in school, which are even more closely tied to the curriculum, girls often outperform boys. A recent meta-analysis of research on the performance of students from elementary age through adulthood found boys tend to outperform girls in more complex areas of math such as those involving more advanced problem-solving. In contrast, there are no differences—and, in some cases, an advantage for girls—on more basic numerical skills and on math problems that have a set procedure for solving them Two of the factors above, age and the […]

Thailand to America… A long Journey

I’ve finally got a new home in the USA and North Calorina is a great place to live! Flying from Thailand to America was a very long and tiring journey. My family still haven’t sold our house and so half of the family’s money is over there. And we’re living poor here, but it’s still fun. We had to fly from my city to Bangkok. Then Bangkok to Hongkong, and Hongkong to Washington D.C. This whole journey took around a week to be in North Calorina. Also, I hate jetlag haha! Enjoy these photos!

I can’t do Chemistry Experiments anymore

Ah, the good old days and my craze for science experiments. It was a fun time but I’m starting to lose motivation and I also don’t want to waste money. Since I’m moving to the U.S.A., I had to sell all of my supplies to someone else and if I move there, I’ll need to buy all of my supplies again. I cannot do this hobby because I’m just bored of it. You might be asking: “Dan, then what are going to post on this blog?” I’ll be posting about other hobbies and blogging about myself. Anyways, right now I’m still trying to get to U.S.A and I’ll get back “the WordPress grind.” Ciao and see you later! My best science posts: 1. Does mercury conduct electricity 2. Turning a coin to silver and gold simple redox reaction 3. How to make basic copper carbonate 4. Pouring super glue into borax Thank you for reading my chemistry posts. It was a fun experience.

Inconsistency…

Hey guys, I’m back. I’m sorry for not posting anything for a while I didn’t have any time to blog because of problems that I had and many other things. Since my school has changed its time and added more study time, I had to be at school for 9 hours. Yes, 9 hours for the whole of September. And […]

Protecting Iron Nails from Rust

Protecting Iron Nails from Rust Rust is an iron oxide, a usually red oxide formed by the reaction of iron and oxygen in the presence of water or air moisture. Several forms of rust are distinguishable both visually and by spectroscopy, and form under different circumstances. Given sufficient time, oxygen, and water, any iron mass will eventually convert entirely to rust and disintegrate. Surface rust is flaky and friable, and it provides […]

End of the week #3 (My exam results)

  Alright so my midterm exam results finally came out, and I didn’t do so well. Here are three reasons why didn’t do well: First, I wasn’t paying attention (I didn’t put effort into getting good grades). Second, I past the 8th grade many times already, and the grades are better than this. And lastly, the test is in a language I’m not comfortable with. My parents were upset that I got these grades, but I wasn’t sad. Because I didn’t try my best (but they won’t listen to me). Anyway, let’s see the grades: Math: D 40% (It was in Thai) Science: C 67.5% (It was also in Thai) Computer: D 56.67% History: C 62.5% Thai language: F 22.5% (There’s nothing I can do) P.E. B 80% English Grammar: A 95.5% (Easy) Social Studies: C 75% And there they are. Plus, nothing really happened this week, except for the grades. I would of gotten better grades if I was paying attention. Thanks for reading.

Mercury Compared to Water

Mercury Compared to Water This is going to be a short post because I’ll be comparing Mercury to Water. I’ll be trying to find out why mercury is 14 times denser than water: I poured all of my mercury into a petri dish and I have 22.70 grams of it. So I added the same weight of water into a petri dish and weighed it. And after that, I pour the mercury and water into beakers to measure them. There are 1.6 ml of mercury and 22 ml of water. That explains why mercury is 14 times denser than water (22 ÷ 1.6 = 13.75 ≈ 14). Here are some more comparisons:  Mercury  Water Color  Metalic Silver  Clear/Transparent Density  13.534 g/cm3  1 g/cm3 Conductivity  High  Medium Toxicity  High  None

Pouring Super Glue into Borax 1

Pouring Super Glue into Borax 1 Everyone has heard about slime from school glue. But I was thinking what would happen if you use superglue instead of just regular school glue. Glue has long flexible molecules in it called polymers. These polymer molecules slide past each other as a liquid. Borax in water forms an ion called the borate ion. […]

I’m Back!!

It’s already turning to December, but I didn’t do anything! (I was gone for a month). But now I’m back to make more posts! Nothing much happened in this month, I really don’t have much time for my blog left since I go to the gym. My dad gave me twice of school work because the gym is in the morning and I’m tired in the afternoon (too tired to study). So I need to give more work to myself on Friday, Saturday, and Sunday. But don’t worry, I went nonstop studying in the middle of nights and now I have less work. Anyways, I’ll be making more posts soon. Bye for now!

Turning a Coin to Silver and Gold (Simple Redox Reaction)

Turning a Coin to Silver and Gold (Simple Redox Reaction) This simple experiment will make you understand the redox reaction. This is one of my favorite experiments so I decided to make a post about it. Things you’ll need: a copper coin (a penny, basically), zinc powder, sodium hydroxide (more than 50%), alcohol lamp, forceps, and a beaker. Pour Sodium Hydroxide into a beaker and pour some zinc dust in it, enough to cover the coin. Put the coin the beaker and wait for a couple hours, I’ll be using my country’s copper coin.   Take the coin out with forceps and wash it with water, now you have a silver coin. If you want to continue, do the following steps: Make sure the coin is dry. Heat it up with an alcohol lamp until it’s yellow. Enjoy. An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two chemicals. A redox reaction is any chemical reaction in which the oxidation number of a molecule, ion, or atom changes by losing or gaining an electron. For example, like this experiment, the zinc transferred its ions to the copper; that’s how the coin turned silver, and that’s why this is a redox reaction. What about turning it to gold? The color of silver and copper are just mixing together when heated and that makes the gold color.

Does Mercury Conduct Electricity?

Does Mercury Conduct Electricity? I bought this from my science shop yesterday so that I could perform more experiments. Why is it a liquid? The reason for mercury being a liquid is complex. It is heavy; a chunk of iron can float on mercury. Compared to other metals, it does not conduct heat well. However, it conducts electricity fairly well. Mercury is the only metal that is a liquid at normal […]

What is Silica Gel?

What is Silica Gel? Silica gel is a granular, vitreous, porous form of silicon dioxide made synthetically from sodium silicate. Silica gel contains a nano-porous silica micro-structure, suspended inside a liquid. Most applications of silica gel require it to be dried, in which case it is called silica xerogel. For practical purposes, silica gel is often interchangeable with silica xerogel. Silica xerogel is tough and hard; it is […]

Melting #2: Copper (II) Sulfate (Didn’t Work)

Melting #2: Copper (II) Sulfate (Didn’t Work) The last time we melted sulfur, and it was really fun (except for cleaning the test tube). Now let’s melt something else, what about Copper Sulfate? Copper (II) sulfate is the inorganic compound with the chemical formula CuSO4. Older names for this compound include blue vitriol, bluestone, vitriol of copper, and Roman vitriol. The pentahydrate (CuSO4·5H2O), the most commonly encountered salt, is bright blue. Melting Point: 110 °C (230 °F) Sulfur’s melting point is 5 °C higher (which means they’ll melt about the same time). It looks impossible to melt it because the sulfur is more (soft) like a powder, but this one is tiny crystals. Let’s give it a try anyway. Light the lamp! OK, it’s heating it up nicely. A couple minutes later: The copper sulfate is turning whiter, but still, all of it still remains solid. But look. There’s water vapor in there. That’s weird, maybe there’s too much heat? But the sulfate didn’t melt yet. 10 minutes later: The sulfur melted already at this time. But the sulfate still remains a solid and it’s just turning whiter. 20 minutes later: This is taking forever! It’s not melting. Did I do something wrong? It’s 115 °C already, and the temperature can go further. I guess it won’t melt anymore so I turned off the heat. Wow! this experiment is a fail. I wonder why it has water vapors? Why is it turning white? When is it actually going to turn to liquid? Any ideas why it didn’t […]

Melting #1: Sulfur (Making a Sulfur Coin)

Melting #1: Sulfur (Making a Sulfur Coin) I’m going to be melting sulfur… Sulfur is a chemical element with symbol S and atomic number 16. It is abundant, multivalent, and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow crystalline solid at room temperature. Sulfur Melting Point: 115 °C ( 239.38 °F) Yay! the sulfur is melting! It took about 10 minutes to melt the sulfur. Now time to pour it into the mold! OK, the sulfur hardened. Time to take it out the mold. I used a hammer to take it out. No! that’s the ugly side. The better side is this:   Wow, I’m actually impressed. You’re probably wondering why the sulfur is brown. Just wait a couple days and the coin will turn yellow. But once it turned yellow, it has a chance to crumble in a month. Because sulfur crystallization is a complicated process. The time it takes is mostly determined by the temperatures the substance was subjected to initially. I’ll be making another post to show you how the color changed. Hope you enjoyed the experiment if you did, drop a like on the bottom ↓ Sources: https://en.wikipedia.org/wiki/Sulfur https://melscience.com/en/experiments/sulfur-melt/

Playing With Black Light

Playing With Black Light I was just looking around the internet for some cool stuff, and I found something that catches my eye. I found black light. A blacklight (or often black light), also referred to as a UV-A light, Wood’s lamp, or simply ultraviolet light, is a lamp that emits long-wave (UV-A) ultraviolet light and not much visible light.   One type of lamp has a violet filter material, either on the […]

I Figured out why the Coins look Different

I Figured out why the Coins look Different Remember the coin experiment that I performed lately? When I washed the coins, they looked different. But why? I finally figured out the answer. Copper metal is oxidized by the Ag1+ to Cu2+ and the Ag1+ ions are reduced by the copper metal to silver metal. But do you remember what the coins are made of? Penny: The alloy remained 95 percent copper and 5 percent zinc until 1982, when the composition was changed to 97.5 percent zinc and 2.5 percent copper (copper-plated zinc) until now. Cents of both compositions appeared in that year. 50 Satang (Thai baht): The core is 99% iron and cladding is 99% Copper. 10 Yen (Japanese Yen): 95% copper, 3–4% zinc, and 1–2% tin. The Penny turned yellow-orange because the zinc was mixed with copper. The Thai coin turned darker because of the iron. The Japanese coin turned yellow because of the zinc and tin. Tin is light yellow and zinc is gray. I hope you enjoyed that experiment, if you did, comment down below ↓ Sources: www.chem.indiana.edu/faculty…/5-5%20Silver%20Tree%20Redox%20Reaction.doc More sources at: The Silver Coin
