February 22 - 26, 2016

This week in Dr. Jones' Biology class, we had a full week of classes. We learned more about genetics, especially the punnet square, and tested our knowledge with different worksheets and activities throughout the week. On Friday, we did an activity where we looked at real genotypes and phenotypes of different generations of fish and saw how they related to each other. We saw how genes are passed down by generation, dominance being a very important factor. I really enjoyed this lab.

This article was very interesting, talking about black holes and many complex theories that are difficult to understand. As we are living in a 3 dimensional universe (4 including time), we can only perceive 3 dimensions. As new research shows, there are probably other dimensions that humans cannot comprehend. A new shape of black hole, a ring with bulging edges, was simulated by an advanced computer recently, and what was discovered could 'break' Einstein's theory of relativity. If this was true, then all of science would come tumbling down on its foundation.

This article was very fascinating to me because I didn't understand parts of it. Black holes are an interesting topic for most, but I find them very intriguing. This new type of black hole, although it might not exist in real life, could still mean revolutionary things for us. It is strange how one simple theory could contradict everything that we have known to be true in physics forever. I would like to learn more about this topic eventually...

"The better we get at simulating Einstein's theory of gravity in higher dimensions, the easier it will be for us to help with advancing new computational techniques -- we're pushing the limits of what you can do on a computer when it comes to Einstein's theory," said Tunyasuvunakool. This quote shows us how much technology is working in our advantage. "But if cosmic censorship doesn't hold in higher dimensions, then maybe we need to look at what's so special about a four-dimensional universe that means it does hold." This is a good point.

In conclusion, I liked this article very much and my question is this: What can we do to discover more about this topic so that we can prove that Einstein's theories are correct?

This week in Dr. Jones' Bio class, we only met three times because we had no school on Monday and Wednesday. On Tuesday, we got our tests back and went over it all. On Thursday, we completed a packet reviewing genetics. On Friday, we did an activity to see if we were a supertaster or nontaster. Apparently, I am a very bad taster...

Article of the Week #?

I found a very intriguing article about a catastrophic but natural disaster that occurred multiple times in the past. A large lake, 1/3 the size of Wales, drained between 8000 to 13,000 years ago, leaving devastating effects on the environment. The climate was affected and also many local animals, causing temperature to drop and rainfall to increase. This was truly an important point in history that we need to see.

I thought that the article was fairly well-written and got some good information out of it. It is amazing to me how a simple natural event could devastate an entire area. However, science shows that it did indeed occur. What can we learn from this and what can we do to prevent it from happening again?

One quote that was interesting to me was this: "This was a massive lake. When it drained, it released around 1150km3 of fresh water from the melting glaciers into the Atlantic and Pacific oceans -- equivalent to around 600 million Olympic-sized swimming pools. This had a considerable impact on the Pacific Ocean circulation and regional climate at the time." I wonder how if it is still around today and if we still face any similar threats. Another quote is this: "The study is important because we are currently concerned about the volumes of fresh water entering the oceans from the melting ice sheets in Greenland and Antarctica and this gives us an indication of the likely effects." I liked this quote because it told about similar things that could potentially have similar results.

Overall, I am left with one question: What do we need to do to stop this from ever happening in the future?

February 8 - 12, 2016

Last week during Dr. Jones Biology class, we did lots of interesting activities. On Monday and Tuesday, we finished up the cancer presentations (we presented last). We had no time to study in class, so I studied at home. We had the quiz on Thursday and there wasn't class on Friday because of our long weekend.

Article of The Week

This article talks about horses and how they decipher human emotions. When showed pictures of good and bad human emotions, scientists knew that they were intelligent. Their reaction when showed a human face depicting anger was understandable, causing the animal's heart rate to increase. This is a defense mechanism that helps the animal see any negative human behavior, such as rough handling.

I thought that this article was very interesting because it talked about the reading of emotions beyond the species barrier. Horses can supposedly interpret human emotions, which is a big discovery in the scientific field. This makes me wonder what other species can do this.

One quote that was interesting to me is this: "Emotional awareness is likely to be very important in highly social species like horses -- and our ongoing research is examining the relationship between a range of emotional skills and social behaviour." I wonder what other tests are being conducted to find out more about animals? Another quote is this: "There are several possible explanations for our findings." It is interesting to me that science can give us facts but it takes more effort to find the reasons behind these facts.

Overall, I really liked this article; however, I have one question: what else can we find out about horses and possibly other animals about their individual abilities?

Last week during Dr. Jones' 4th period Biology class, we did a lot of work. On Monday, the 1st of February, we had a quiz on Meiosis, what we learned the week before. Later in the week, we did a lab where we extracted sperm from sea urchins and looked at it under a microscope. It was a very interesting lab that I learned a lot from.

This article was very interesting. It talked a lot about ancient animals and what special traits some of the m had. For example, an ancient dinosaur-resembling animal had a horn shaped organ that might have emitted a sound similar to that of a trumpet. Although no such animal exists today, it is still a fascinating discovery.

In my opinion, this animal would have been very unique when it was around, being able to make loud noises whenever it wanted. It had freedom to use its horn, which is an interesting idea. I wonder what this could tell us about creatures of the past and possibly creatures of the future.

One quote that stood out to me was this: "hadrosaurs are sometimes referred to as the 'cows of the Cretaceous.'" I wonder why this nickname exists and how it relates? Another quote I found was this: "Vocalizations can alert predators, and moving their calls into a new frequency could have made communication safer." This is a good quote because it tells what these horns were actually used for.

In conclusion, I really liked reading this article and I would like one question answered: Is this discovery actually important to science and if so, what could it potentially do for us?
