Summary

This week, we have done many things. For example, we worked on two gizmos, and did an experiment all relating to the ecosystem. Throughout this week, I have learned many things. On Monday, we were given a gizmo. For the two class period, we worked on the gizmo, seeing what would happen if we cut down a certain population. Then, the next class periods, we did an experiment kinda like the gizmo. We were given four cups, each cup having different numbers of wholes in the bottom. We put the cup full of water in the graduated cylinder, then pour it into cup one, two, thee, four, back to the cylinder. At the end we see how much water is left. We did three times. See how much energy/water is left. That is the water efficiency. On Friday, we were given another gizmo. This gizmo, we learned what would happen if you increased a certain population. In the first gizmo, I learn what would happen if I would cut down a population, like trees. In this case, animals including humans would die, because we wouldn't have oxygen to breathe. In the second gizmo, I learned if what happen if you increased a certain population. These all tied into the ecosystems, which helps us. Ecosystems are made up of living things.As you can see, I have learned many things this week, like water/energy efficiency, and increasing and decreasing a certain population.

SP6 - Constructing explanations, and designing solutions

I would say I explained something through my work. This week, we had to do a few gizmos and an experiment. In the gizmo, I had to explain why I think something is correct. And in the experiment, after we looked at some patterns, and we explained why this is. For example, one question was something like "Why do you think this would hurt the animals?" I explained why. As you can see, I used some explanation in the work.

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
