Mixing Colored Sugar and Liquids

dpantchev26 on

Today in Science, we mixed colored sugar and liquids. The liquids we mixed with colored sugar were oil, vinegar, and water.

The way we made the colored sugar is we took 4 teaspoons of regular sugar, and then we squirted some purple food coloring onto it. After that, we mixed it until all of the sugar was purple.

The first liquid we mixed with colored sugar was oil. Our hypothesis for this was: If we put the colored sugar into the oil, then both materials will stay separated and the color will stay in the sugar. Our hypothesis was correct: They both stayed separated, and the color didn’t spread.

The second liquid we mixed with the colored sugar was water. Our hypothesis was: If we put the colored sugar into the water, then the color will spread and the sugar will dissolve. Our hypothesis was confirmed. The color spread and the sugar dissolved.

The last liquid we mixed with the colored water was vinegar. Our hypothesis was: If we put the colored sugar into the vinegar, then the sugar will dissolve and the color will spread. We were only half correct: the color spread, but the sugar did not dissolve.

Overall, I had a lot of fun doing this project and learned a lot. Thanks for reading!

Mixtures and Solutions

Today we played a match game. It was called “Match It!” Basically, we had to flip the cards over, and then Sam (my partner) and I would flip two cards at a time. If we flipped both the term and its definition, we got to keep that set of cards. Whoever had the most cards at the end would win. At least that’s how I think you play the game. There was a bit of confusion. Sam and I didn’t really know who won, though, because like I said, there was a bit of confusion. I learned a lot from that, and it was pretty fun too! These are some pictures from the “Match It!” game:

We also sorted lettered and colored cubes. Basically, there were maybe 100 little cubes each with a letter and color on them. What Sam and I decided to do was sort them by color. There were six different colors and a whole lot of cubes, so it was hard work. But in the end, it was really satisfying to see all the cubes in their own color spot. If I remember correctly, the colors were pink, orange, green, blue, purple and yellow. I learned about Chemical Elements and Compounds from this project. Here’s a picture my group took while sorting the cubes:

We also watched a video and took a test. I got 7/7 on the test! It was really informative and I learned a lot!

I really enjoyed this experience and learned a lot! Thanks for reading!

 

Rube Goldberg Blog Post #6

dpantchev26 on

Today we shared our videos. I was kind of nervous to share mine, but I think Michael and I did pretty well. I think Ms. Boyer liked ours. I was kind of embarrassed to share my work because I kept thinking “What if they don’t like it” or “What if I did bad”. After I shared it though, I don’t think anyone thought it was bad. We made some edits to the video and changed it up from the video I put in my last post. This is the new and improved one:

The video was fairly hard to make and took a lot of time and effort. I think it came out well. This is my last blog post about Rube Goldberg. Thanks for reading!

Rube Goldberg #5

Our Rube Goldberg worked! We successfully knocked down a bowling pin with it! We also finished our video. I know I said it would be in the sixth blog post, but the excitement is too much to bear. This is it:

 

If you didn’t think that was AWESOME, then I think something is wrong with your awesome meter. After that success, we were so excited. The big thing going through our brains was “It finally worked! It finally worked!” We added some fails to hit high on the rubric. We made this with WeVideo because that was really convenient, and we already had accounts and knew how to use it. We might make some last minute edits, and if we do, I’ll put it on my 6th (maybe even 7th) blog post. Michael and my schedules rarely both have free time, so he usually can’t come to my house and I have to work alone. Its much harder working alone because you have to do 2 times as much work as if you were doing it with a partner, but what’s good about working alone is that you have no one to argue about ideas with, and you know you’ll do what is in your mind right. My mom usually subbed for him though. But it was helpful to run ideas by him, even if we had to do it through text. That concludes my 5th blog post. Thanks for reading!

Rube Goldberg #3

dpantchev26 on

This is my third Rube Goldberg blog post. My friend Michael and I have worked a lot on this project. If you don’t already know, a Rube Goldberg is a very complicated machine which is supposed to complete a simple task. Our simple task is knocking down bowling pins. We had to have at least 8 steps in our Rube Goldberg machine. Every transfer of energy counts as a step. A transfer of energy is when one object has energy and then hits another object, so object #1’s energy goes to object #2, which causes object #2 to move or hit another object. Michael is coming to my house later today to work more on the Rube Goldberg machine. We have worked very hard on this project, and we hope it works on the first try! But Rube Goldberg machines don’t usually work on the first try because if one of its many steps malfunctions, the whole machine won’t work! This is usually what happens. But we have hope!  Some of the difficulties I have encountered are that it sometimes fails and even if I get frustrated, I have to try again until it works. One time this happened is when I dropped the ball through the tube, it wasn’t perfectly in line with the big domino, so it missed. Another time this happened is when the small marble didn’t have enough power to move the big marble. Also, it was hard deciding what steps would make the cut and be in our Rube Goldberg, and what steps wouldn’t work. This is a picture of our Rube Goldberg so far:

 Stay tuned to hear more about our Rube Goldberg, and in the last post, I will include a video of our Rube Goldberg in action!

Ways I Can Reduce My Waste

dpantchev26 on
  1. I can bring my own fork to restaurants.
  2. I can not get straws and drink without them.
  3. I can recycle instead of throwing things in the trash.
  4. I can take apart products before recycling them.
  5. I can use a reusable bag instead of getting a plastic bag and throwing it out.
  6. I can try to reuse things instead of throwing them away.
  7. When something breaks, I can try to fix it instead of throwing it away.

It was kind of hard to think of some of these because I initially didn’t think of that many. These are not hard to do. They only require a little extra effort. I would feel good after I do these because I know I just saved the world from the trash I was about to throw out.

Rube Goldberg Blog Post #1

dpantchev26 on

Today my friend Michael and I started something called Rube Goldberg. We set our things up in my upstairs bathroom. We know what we want to accomplish already. We are attempting to turn on a phone, which is a simple task, but we have to do many complicated steps achieve it. We have already created a sketch and thought about what materials we will use. They include Dominos, Marbles, Toilet Paper Roles, and Wooden Blocks. Stay tuned in my feed to learn more about Rube Goldberg and follow me and Michael across our steps, our tries, and our fails.

Isaac Newton Biography

Isaac Newton Biography

 

Have you ever heard of Isaac Newton? If you haven’t heard of him, then keep reading! Isaac Newton was born in 1643, on January 4th. He was born in a Manor called Woolsthorpe Manor, in The United Kingdom. When he was a child, he was playing with his friends. He got really tired and sat under an apple tree. Then an apple fell on his head. That was when he discovered the 3 laws of motion.You can learn more about that in my infographic at http://blogs.scarsdaleschools.org/dpantchev26/2018/10/24/isaac-newton-infographic/

At age 17, his mom told him to become a farmer. If he had listened, we wouldn’t know about gravity! He also discovered f=ma, which means Force=Mass x Acceleration. Many people know that he was knighted. That means that instead of calling him Mr. Isaac Newton, people back then called him Sir Isaac Newton.

He was knighted not because of his many great discoveries, but because of the fact that he worked in the Royal Mint. The Royal Mint controls the money in the United Kingdom. Back then, there was a team of scientists called the Royal Society. They were the most respected scientists in all of the United Kingdom. And Isaac Newton was the president of the Royal Society. Now that you know all about Isaac Newton’s life, you can learn more about his discoveries in my infographic in the link above! Thanks for reading!

Blog Post #2

My class has been studying plants. We have 2 plant quads. One is called control and the other one is called experimental. Our group question was “Will a plant grow in rocks instead of soil?” Our hypothesis was ” If we plant a seed in rocks instead of soil it will not grow because the water will evaporate on the rocks. Also, The plant will not get nutrients that the soil has.

 Here are my control plant “stats”. They got everything that they need like water, soil, sunlight, air and nutrients. They also got fertilizer pellets. They are 11 cm tall. They grow about half an inch a day. They are green and have 15 leaves so far. Some plants are drooping down, but most are pointing up. I can’t believe that my group’s plants has grown 11 cm! They are really good, unlike our experimental plants. But that is in the next paragraph.

Our control plants have been growing really well. They are 11 cm tall and they are green. They have 17 leaves.

Our experimental plants have not been growing at all. They are in rocks instead of soil. They got everything they need like water, sunlight, air and nutrients. They also got fertilizer pellets. But they got rocks instead of soil. They are obviously 0 cm and do not have a color. I think this is because the water evaporates on the rocks every time we water them. Also, the rocks do not have nutrients that soil does. If you want proof, look at the picture below.

Our experimental plants have not been growing at all.

So far, our hypothesis is correct. I wonder what will happen next?
