Weekly Blog : Victor Nguyen 8B Summary Evolution. That is, evolution is any change in the heritable traits within a population across generations, which means descent with modifications. Healthy living things can make copies of themselves. For example, A and B can mate and make AB, but if there is any change, then evolution has occurred. You can refer the Five Fingers of Evolution, to Mechanism of Evolution. The first finger or the pinky represents that population can shrink. For instance, if no one mates with C, then it will, so forth... The second or ring finger represents mating/sexual reproduction. This is where 2 mates have a baby(ies). The third or middle finger represents mutation - when there's a change in the DNA. The fourth or index finger represents movement/gene flow - when gene moves from one population to another. These four fingers are the cause of evolution. The last or the thumb represents natural selection. This is only one that can lead up to adaptations,

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

Geologic Time Project Blog: Victor N. 8B Image link: My phone Summary This project was quite interesting to me. I learned many things about the geologic time. We use the geologic time scale to look back at Earth's history in different sections. The biggest chunk in Earth's time is called eons, which is split in 4 eras. Eras is the second biggest piece in Earth's time. Eras are split into different periods, which is the smallest piece in Earth's time. The first era, the Precambrian era, is known to be the Age of Earth and Lava. The era is split into 3 periods, The Hadean period, The Archean period, and The Proterozoic period, which all happened about 4.6 billion years to about 600 million years ago. Throughout the era and periods, Earth was created through rocks, and large fragments of dust and debris. The second era, the Paleozoic era ended the Precambrian era and, is known to be the Age of Fishes. The era is split into 6 periods: the Cambrian period, the Or

Weekly Blog : Victor N. 8B Researching the Mesozoic Era Learning about geologic time Summary: This week, I learned many things, from the geologic time scale to the Mesozoic era. On Wednesday, Abram asked Ms. Garica, "What is the meaning of life?" She replied by showing the entire class a video about this: in one "year," the earth was created to having the technology that is today. This shows that our life is short, and that it can go by in a blink of an eye. Then for our project, we have to research our own era to then put together with the rest of our group. My era is the mesozoic era. I learned that the Mesozoic era is the age of dinosaurs. The mesozoic era lasted about 245 million years to about 66.4 million years ago, which was split into 3 periods: the Cretaceous period, the Jurassic period, and the Triassic period. At the beginning of the triassic period, Earth's continents were still welded together which is called the Pangea. That lasted  un
