Cladograms - Evolution IV - 10/22/17

Weekly Blog : Victor N. 8B

Summary:

You need a diagram to see how things are related to each other, right? Cladograms help us identify relationships between organisms. They show common traits and characteristics, and common ancestors of different species and organisms to see how they are closely related. In a cladogram (picture above), you can see there are 2 parts, the name of the organism and the name of the trait/ancestor. The more characteristics the organisms share, the "down the telescope" it is. In the cladogram above, you can see that the chimpanzee has all the trait below it, from common mammal ancestor to common vertebrate ancestor. The chimpanzee is closely related to the bear because it shares more common traits. The word species in Latin means kind. Species are groups of interbreeding organisms that do not ordinarily breed with members of other groups. You can classify life different ways, but to see the relations between different organisms and to see how closely related they are, you can use a cladogram.

SP2 - Using models

To understand more about classifying life, my table group and I have been working on many activities that shows and teaches us how to make a cladogram. After making and a cladogram, we identified the different organisms. After looking at the cladograms, we saw which organisms are closely related by looking at the common characteristics. As you can see, my table group and I worked on worksheets and activities involving cladogram to practice classifying life.

XCC - Patterns

Through the 4 weeks of learning about evolution, I learned and have noticed more patterns in evolution. Like I said earlier, the more characteristics organisms share, the higher place up the organisms will be. This also means the more characteristics you share with another organism, the more closely related you are to that organism. In the cladogram above, you see the organisms: lamprey, sunfish, newt, lizard, bear, and chimpanzee, and you have the traits: common vertebrate ancestor, jawed vertebrate ancestor, tetrapod ancestor, amniote ancestor, and common mammal ancestor. The cladogram starts with the lamprey having a common vertebrate ancestor. Next, you have sunfish which has all the common traits below that, the common jawed vertebrate and common vertebrate ancestor. This goes for every organism to the last. In this case, the last organism is the chimpanzee which has common vertebrate ancestor to common mammal ancestor.

This week I was a wanderer because I have noticed many things, such as more patterns in evolution.

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
