Roller Coaster Project Blog : Victor N. 8B

Summary

A roller coaster is a track with an operation, that could be a car or cart. There are different elements into a roller coaster, that includes a hill, turn, and a loop. Roller coaster have certain factors that add thrill to the ride, aka "thrill factors." In this Roller Coaster project, we are to create a roller coaster using tubes, dowels, and tape. The roller coaster can only be inside the 4ftx2ft base, and must have a safe stop. I learned that we need to be precise of where we place the tube. If we don't, the tube might be placed wrong, and that will affect our ride. We learned to fix our mistakes, by modifying and making any changes as needed. The ride ended up working as planned.

Backward-Looking: What problems did you encounter while you were working on this piece? How did you solve them?

We had encountered some problems while working on this project. For example, when creating our hills and turns, we didn't have the right position which caused the marble to fall off the track and not go through the entire runway. Another problem we had was keeping the dowels upright. A dowel itself will not fit into the holes of the base. We fixed that by adding tape around it to fill up space. We also added some support to it. As you can see, we encountered some problems but found a way to solve them.

Inward-Looking: Have you changed any ideas you used to have on this subject? 

When starting this project, we had some ideas for our roller coaster. One idea was kind of like a water slide, and the other idea was a "pretzel." We did one of them, and made the water slide. After looking at the requirements, we didn't have a hill. By adding both a pretzel and a hill, it would not fit so we only added a hill to fit the requirements. As you can see, we changed our ideas that we originally had on this project.

Outward-Looking: What grade would you give it? Why?

I would give this project a grade of B+. I'm not being harsh on myself, nor my teammates. My teammates might give this project, an A. I would give this project a B+, because as of right now, it's kinda plain. Even though the requirements do not include decorations or prettiness. We are graded on the looks, but I feel like we can decorate this and clean the tape up a bit. As you can see, I would give this project a grade of a B+.

Forward-Looking: What would you like to spend more time on in school?

If I had more time in school, I would spend it with my group to continue to construct our roller coaster. Yes, we can build a roller coaster in 1 week. But, if you want to make it look perfect and nice, and finish the analysis and design, we would need at least 1 week. It has not been a week, and we already got the roller coaster, without decorations, and most of design brief done. If we had 2 more days, we would have the entire project. As you can see, we would spend more time in school on building the roller coaster.

Should We Bring Back Extinct Species? - 12/14/17

Should We Bring Back Extinct Species? by: Victor N. 8B Heard of de-extinction? De-extinction is the process of resurrecting dead species. Now, why are we even thinking of bringing back extinct species? Isn't it humanity the reason why some species are extinct? Isn't over-population the reason for global warming? So if you bring extinct species back, aren't you populating the Earth even more? We shouldn't bring back extinct species, because the risk of hurting the environment is much higher than improving it. Scientists are working together to bring back extinct species through DNA, cloning, breeding, and genome editing. In the Reawakening Extinct Species article (source 4), scientists used the cloning method to bring create a bucardo kid. They transferred the nucleus of cells into different cells and used electricity to grow embryos. Unfortunately, the bucardo kid died few minutes after its birth. Using this method, the chances of the bucardo kids surviving

The Pipe-a-Phone Project Blog - Sound V - 4/22/18

The Pipe-a-Phone Project Blog : Victor N. 8B Summary Frequency is the rate at which waves pass in a given time. Pitch, however, is the highness or lowness of a note. The relationship between the two is that frequency influences pitch. If there is a low frequency, there will be a low pitch. The appearance of the wave changes with a change in the pitch because of the higher the pitch the shorter the wavelength. The appearance of the wave changes with a change in the volume because the louder the sound, the larger the amplitude. When you play higher notes, the waves are closer together. Yet, when you play louder, the waves are taller. 'Musical instruments create sounds that can be varied in pitch and volume.' Some instruments give pure tones while some produce a mix of frequencies. Musical sounds are created from vibrations from the device in the instruments. Our task is to use what we know about musical waves and sound and to create an instrument that could play 8 tuned

WAC #1: Is it More Important to Reduce, Reuse, or Recycle - 9/22/17

WAC #1 - Is It More Important to Reduce, Reuse or Recycle: Victor N. 8B Now, is it really important to reduce? Reuse? or Recycle? But, which one is more important. For the short answer, it's important to do all of them. However, there is always one that shines out and is the most important of all, and that is reduce. To summarize, reducing saves you less work than reusing and recycling. I like to think of that's why they put reducing in front of the three R's. Reducing is the best thing to do, you don't even have to anything [to hurt the environment]. For every time you go to the store or restaurants, you come back with packaging materials such as plastic bags and containers. That right there ends up in landfills. According to Bethany Wieman of SFGate in her article of What is Reduce, Reuse, and Recycle? Today each person creates 4.3 pounds of trash, a day. By reducing, you are cutting back on anything, like getting containers, saving water and energy, etc... Again

End of Year Project Blog: Victor N. 7A this is our project build/prototype.  Summary This project was quite interesting. Instead of writing about the whole project, I will be focusing on the science portion of this project. In this project, we are to look a different environmental accords, chose one and research different clean cities to look for that accord. We chose the accord, transportation and the city, San Francisco. We learned that San Francisco wasn't always a clean city, because from the all the vehicles driving around which causes pollution to the earth. But then they decided to resolve that. They did by having people drive more eco-friendly vehicles, like electric vehicles. They also suggest people to ride their bikes more. As you can see, San Francisco wasn't always clean city, but they decided to resolve that problem. Backward Looking I didn't really know much about this project, before we started. But I did know that urban village needed somethin

Musical Instruments - Sound V - 4/15/18

Weekly Blog : Victor N 8B Image Location Summary 'Musical instruments create sounds that can be varied in pitch and volume.' Some instruments give pure tones while some produce a mix of frequencies. Musical sounds are created from vibrations from the device in the instruments. Those devices are wires in string instruments like guitars, drums, and/or reeds in woodwind instruments such as clarinets, oboes, and saxophones. Wires in instruments can affect the tune and frequency of the sounds. They create music when you tap or pluck the string, which vibrates and create compression waves in the air. The sounds of drums are created when striking the head, which vibrates and create sounds. Finally, reeds create sounds when you use your tongue and blow on it, which vibrates and create music. In conclusion, musical instruments create sounds from vibrations and can have different pitches and volume. SP2 - Using Models This week, I used models to demonstrate my understandin
