Science Fishing Rod With Electromagnets!

Science - Fishing rod with Electromagnets! 

In science class, we recently started a new unit called electricity. After learning a little more about how a lightbulb works and why it works, we moved on to learning more about electromagnets. As our homework, we learned about what it electromagnet and electromagnets are technically created when you wrap a wire around a nail. After learning that we need to build a fishing rod, we started planning out ideas and how our fishing rod would be like. Here’s all of our drafts down below. 

The first draft - Down belong is a picture of my first plan that both me and my partner, Elina, drafted. This picture technically explains that the long wire is attached to the battery holder (with batteries) and  also wrapped around the nail down below. Then again with the other side of the wire, it is also attached to the battery holder on the other side. The only thing that was good about this fishing rod was that it has a complete circuit, which was really important to have because that’s how the nail can pick up the paper clips. But there was also negative things which was it was too weak (it can only pick up 2 small paper clips at once) and also, there no switch. 

The second draft - For our second draft, we decided to add a switch and also make sure it has a complete circuit. After listing a bunch of ideas of what we can use as a switch, we finally figured that we would use thumb tacks and a paper clip. The paper clip can be the one that controls if the circuit is going to be complete (when the nail can pick up paper clips) or if the circuit is going to be incomplete (when the nail can’t pick up paper clips.) So here’s our draft: 

Some of the good things is that it has a complete circuit like before, and also, it finally has a switch. We also realized that the switch makes the fishing rod slightly stronger. From only lifting up 2 paper clips to lifting up a big purple clipper. Though some things we could have changed was maybe making another switch because our switch wasn’t as fast as some of the others. 

During our fishing derby competition, we decided to stick with our second design. In total, we got 305 points! 

Quizlet of Everything!

In this unit, we are learning about electricity and how things lighted up. So in this case, we made a game about it. This game is worked by having one wire on one side while the other wire is where the questions are. As you can see, I have scrambled up the answers, so you have to connect the red wire to the question you're on (the left) and find the answer on the right and connect it in order to have a complete circuit. The picture on the left is the front, and the picture on the right is the back. Today, I'll be explaining how this works.



First off with just a brief summary of how you can make a complete circuit, you would need a voltage source (in this case, we're using a battery.) a conductor, (we're using aluminum foil as you can see in the picture on the right) a resistor, (we're using just plain old tape for this to make sure the path is making a full circuit.) and also, a path. When you have a complete path, that is when you have a complete circuit! How does that work though? Well, here's diagram that I drew:

This diagram is showing us how a normal circuit works. All you need is a lightbulb, battery(s), and some wires. In this case, we're connecting the wires with the battery and the lightbulb that's letting the electrons flow freely in the wires and also forcing electrons to go through the lightbulb in order 'travel' to the other wire. As the electrons flow through the lightbulb, it lights up! The game that I made was something similar, except, the aluminum foil is connected to the answers and questions. 

THE GAME: 

As I had explain on the top, the game basically works by having the red wire that's on the left and having the black wire on the right. Questions are on the left and answers are on the right. For each question, there's suppose to be a correct answer listed. When you find that answer, you put the black wire on the answer hole and the red wire on the question hole. If your light lights up, that means you got the answer right. Furthermore, that also means that you created a complete circuit. How? Well as you can see behind the game board, there's aluminum foil and tape behind. Aluminum foil is used like a wire to let electrons move freely and travel from one wire to either another wire or a lightbulb. In this case, I placed the aluminum foil to where the answer was and where the question is. So when you get the right answer, electrons can cross threw that path in order to light up. The reason why we used aluminum foil is because as studies were done, they thought that all kinds of metals, irons, or steels work the best. Though somethings that can't be used to let electrons move freely are plastic, wood, etc. These are called insulators. With insulators, your circuit is going to be incomplete. So, we used aluminum foil instead. You may be wondering, Why would it still work if you put aluminum foil on top of every single question? Won't it connect to each other? The answer to this questions is no because we used tape. Tape is our resistor here, meaning it's the one that protects the aluminum foil from affecting other aluminum foil lines. Tape is really important here because without tape, people can get the answers wrong but the light can still light up because it's all connected. With all these objects, it works because electrons started from the voltage source (battery) and goes threw the wires, into the alluminum foil with tape protecting it, and back out with wires and into the voltage source again. When that all happens, you finally have your circuit complete and a complete path!!!!!

Water project - Week 1

The Water project - Week 1

Thursday:
As we were starting to suspect if we should start working on the water project, we first planned week one as a 'poster-making.' Many asked if we had started the water project yet, the answer to the question is 'I don't know.' Apparently, many of you guys were expecting to be a yes and we were also starting to freak out when we realized it was Thursday already! So we got ready with our computers and planning sheets and started to get some work done. The plan was that Michelle would be doing the bake sale poster and I would be doing the poster that tells others what the Water Project is and how we can help with this cause. So here's Thursdays poster:

Friday: 
On Friday morning, Michelle told me she was already done with her poster. I was starting to freak out because you can tell I still had a lot of work to do. I was also starting to get worried because next week is all about baking the cupcakes for the school and I thought about what would happen if I don't get this done by the end of the week. I started working on it for a really long period of time and so I first started with maybe adding a little introduction:

Saturday:

Finally, it was Saturday. Only one more day till it's due. I thought as I woke up. So I quickly went into the bathroom, washed my face, brush my teeth, and started working on the poster again. Over the past few hours, I tend to get up, stretch for a while, eat something, and maybe watch my brother play his wii. The first poster that I made was like this: 

After lunch, my partner, Michelle Chen, thought it wasn't really eye-catchy because it had too many words. So I tried moving the text boxes around, thinking of another way to fit all these words. Although afterwards, Michelle told me it just had too much information and we can probably cut some out. So just like the morning, I tend to get up and stretch for a while, eat something, and maybe watch my brother play his wii. But finally, we came up with a poster that would fit perfectly and attractive: 

Ratings: 

On a scale from 1 being the worst and 10 being the best, I think I'll give myself either a 7/8 because I could have started earlier. In other words, maybe being more organized and keeping up with what you've planned before. 

One thing I liked about this:

I really liked how I would make mistakes because then I get to learn and solve my way through this project with having to be dependent on others.

One thing I could do differently: 

Next time, I could maybe add more information and a little more about the water project. For example, I can explain why we're doing this project, what is this for, etc. 

One thing I learned from this project:

❤ You shouldn't procrastinate and always be committed to your plan. 

❤ Never be afraid of your mistakes, just learn from them

❤ ALWAYS BELIEVE IN YOURSELF.

Wretched Beasties

 Tubifex worms are normally found in groups and can be found in lakes and rivers. Many people say they cause many bacterial diseases because of the habitat that they live in. Also, lots of people also say they can survive in the sewage, sludge, etc. and that's why they're also known as sewage worms and/or sludge worms. In this world, there is about 12 species of tubifex worms. One of the most well-known kinds are called 'Tubifex tubifex' and can reach around 20 cetimeters!!

As you can see them under a microscope, the tubifex worms are kind of red because they have something called a haemoglobin. A haemoglobin is a part of the body that allows them to live in different places. (Like the sewage, mud, sludge, etc.)

WATER research - science

1. About 15 million kids that are under the age of 5 die every year because of the diseases that are caused by drinking the water. (Water pollution, etc.) 2. Water is made out of hydrogen and oxygen. 3. About 70% of earth is water.

One thing I learned from this unit was density. Density is the amount of mass per cubic volume. And the formula for density is mass divided by volume. I learned something about  this because Mrs. Hill taught me about a heart, and if you spilt the heart in half horizontally, there's a M and the top and a V at the bottom. The line sometimes represent divide in division. So M= Mass and V=volume. Mass divided by volume equals to density. I think one of the most memorable and meaningful things I did was the submarine because that taught me how to problem solve and to revise over and over again if I didn't get something or if it didn't become successful. It was also meaningful because it taught me that different people can have different ideas. Another thing that was memorable and meaningful is the layers of liquids because that also had to do with density. For example, the bottom color is at negative buoyancy because the liquid is denser than the others. And this is meaningful because I learned more about density and understand it better than before.

Cartesian Divers. (Homework)

         A cartesian diver is a bottle that has some kind of object inside with water. Like a pipette, (what we used in class.) And you can make it float or sink or make it stay in the middle. During class, we learned that if the mass and the volume are the exactly the same amount, then the object would stay in the middle. But if the mass is the smaller number, the the object would float. And if the mass is bigger than the volume, the object would sink. We also learned about density during class and the average density of water should be 1g/cm3. If an object floats in the water, it has a density thats less than 1g/cm3. If an object sinks in the water, the density is more than 1g/cm3.  

We also learned about positive buoyancy, negative buoyancy, neutral buoyancy, and ballast. Positively buoyant means when the object is floating up. Meaning the density is more than 1g/cm3 and the mass is less then the volume. But negative buoyancy means the object is sinking and the mass is more than the volume. And the density is more than 1g/cm3. Liked you guessed, neutrally buoyant means the object is in the middle. Meaning the density is exactly 1g/cm3 and the mass is the same as the volume. Also, ballast means any material you use to help it sink. The density of something can change it you change the volume or mass. And the formula of getting density is if you draw a heart in between, the you would see a M or top and a V at the bottom. M stands for mass and V stands for volume. So the equation should be mass divided by volume.

Finding the volume of me!

Volume

Volume is the amount of space that takes up. Volume of liquids means how much liquid is inside the beaker/ container/ graduated cylinder/ etc. To measure a small amount of liquid, you use litters. But to measure even smaller amount of liquid, you use milliliters. When you are pouring liquid into the graduated cylinder or other things, you would have a little bubble on top that's called a meniscus. In order to read how much liquid there is, you need to read the bottom of the meniscus.

Cyberbullying

      Cyberbullying

Have you ever typed mean things about your friend or even anyone? Have you ever sent out something embarrassing to the public about someone you hate, And then made fun of it by writing mean comments about? Think about it. Have you actually may have done that before, but then didn’t notice. This is called cyberbullying. Cyberbullying is online bullying. Which is talking online and saying something bad about someone. It could be chatting in gmail, or any kind of chats. You can be talking to your friends about how one of your classmates in your homeroom is really stupid online. Then everyone can see it. Everything you do leaves a footprint online. And it’s permanent there. Meaning it’s there forever! So make sure you don’t cyberbully others.

I used to think no one can see what you’re doing because once you delete it, it says it’s deleted and goes right into the trash can. But then I learned that people can scan the page you were on, and then forward it to his/her friends. Making other people know about. So if you do write bad comments about someone, others can see it, and it can hurt other peoples feelings. How I learned this was because in the computer boot camp, we watched a video about how anybody can see what you’re doing. Even now! So please, don’t do anything before you thought about it.

This learning changed my thinking on how the internet is safe. Because I never knew that people can track you and then still see what you were doing that time. So if you give your personal information, (Like passwords, where you live, phone number, etc.) then people like robbers can hack into your home. And this will impact my future because now I know that I should be more careful when I’m using the internet and not leave anything personal online. So for the big take away, I think it’s “think before you act.” Because if you thought about what you were going to do, you would know what’s right or wrong. (Or what you can and can’t do.)
