Punnett Squares - 1/15/2017

Summary

This week, we have been doing some similar things like in the past few weeks. We continued to work on our superhero project, and learning about punnet squares, seeing what is the possibility of a gene. Throughout this week, I have learned many things. For example, there are 2 principles. The first one, the Principle of Segregation. Mendel decided that sex cells - sperm and eggs - contain only half of the genes from each parent. The second one, the Principle of Independent Assortment: genes for different traits distribute independently of one another when garnets  are formed. This is just saying there are different possibilities. Look above in the image, the probability of getting brown eyes is 75%, because 3 of the squares have a dominant genotypes. As you can see, I have learned many things this week, like you can see the different possibilities by looking at the phenotypes and genotypes in a punnett square.

S&EP7 - Engaging in Argument From Evidence

I would say I used argument from evidence. For example, in the past five class periods, we had to fill and answer many worksheets about punnet squares, and see what is possibility of a trait, of dominant heterozygous or homozygous traits.  When I answered the questions in the worksheet, I had to explain why. As you can see, I used evidence to defend my explanation.

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

EOY Project Blog - 5/21/17

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
