Geological Timeline Individual Reflection

     In this project, we made a geological timeline to show different events in the course of Earth.  I found that there are three events in Earth's history that stood out to me the most.  The first event is the diversification of vascular plants.  A scientist can look at fossils to see that more plants are around but plants increase the amount of oxygen and decrease the amount of carbon dioxide in the atmosphere, making Earth more habitable.  This eventually led to different mammals and eventually us, humans, living on the Earth in a suitable environment.  The second event is the Permian Extinction.  An extinction may seem like a bad thing, but this allows newer and fitter animals to roam the planet.  Reptiles, marine, and terrestrial organisms radiate during this period while many present day insects dominate.  This is a significant event in Earth's history because many of the larger animals went extinct while the smaller animals survived.  This can be seen as natural selection, as I learned in Biology class.  The third event is the origin of primate groups.  The arrival or primate groups are important to us because it gave rise to humans.  Without these primate groups existing, we may have never existed on this planet or we would have been significantly different.

     During the course of this project, we discovered more and more about how long Earth has been existing.  Since astronomical numbers such as light years are hard to comprehend, the Earth's scale is a little more understandable.  Earth's history is can be measured with eras and periods.  In the beginning eras, nothing much happened because the Earth is still taking its shape.  However, as time progresses, Earth undergoes more and more events.  Eventually towards the end, there are so many things happening it is hard to draw and write all the major events.  The amount of events that happened towards the end of the timeline really shocked me because the events seemed like it all happened in the recent years.

     The amount of progress humans have made during such a short amount of time has really left me dismayed.  We have been around for such a short amount of time, yet we still find ourselves asking each other to stop and save the environment.  All the mammals that lived before us managed to not destroy the Earth for a long amount of time.  However, we perform such detrimental actions such as the burning of fossil fuels and throwing plastic into the ocean.  We have managed to hurt the Earth so much, but we also have had many important discoveries such as writing with pencil and paper and high tech things such as the internet.  All the things we use today were discovered by someone not too long ago.

     I still wonder about how much longer Earth's history will be.  I learned about how we are only in a blink of an eye in terms of Earth's history but I do not know how much longer it will be.  I do not have an estimate because if we are only a blink of an eye, the history would be so large one could not comprehend.  Also, I wonder about the different actions we perform that hurt the environment.  Burning fossil fuels really hurts the environment, but I do not know how much longer we could really keep doing this and still living on Earth.

The Latest Check In - 3rd 20 Time Blog Update

     After working on my 20 time project for a good amount of time already, I have learned many things about my subject.  Since I am creating an experiment, I need to first gather information.  I have already gathered enough information about my topic to understand what is going on.  Since I am working on sleep and memory, I learned about the different sleep patterns and various beneficial ways to study and memorize concepts and words.  Through the course of this project, I have learned many things about myself.  Over the course of this project, I have learned that I work very productively in the amount of time in class.  The classroom is silent which causes me to focus clearly on the task I am working on.  Also, I have learned how creative I can be to solve various problems.
     Through this project, there have been many setbacks and things that hold me back from my desired goal.  The first setback I encountered is that I need to find the words, concepts, or diagrams I need to give to the people performing my experiment.  Recently, I have been using random word simulators to form random words.  Now, I have been moving into grasping concepts from biology.  For example, this can be things we learned about evolution and photosynthesis. After I gather enough of these, I can move onto creating diagrams.  These diagrams can also be from my biology vodcasts or even be other geographical maps.  The main setback that has be pulling me back the most is that I need to spend a lot of time finding things for my experimental people to study and memorize.  In the next class, I plan to handle this setback by gathering various things to study from my biology notebook and going online to finds various concepts and diagrams to study.
     My next step in my 20 Time project would be to finding a lot of people that want to perform my experiment.  Since I have finished gathering information, forming a hypothesis, and forming an experiment, I can now run my experiment.  To run my experiment, I will need people to run my experiment.  I can do this by asking my friends to do it.  I will give them my procedures and once they finish, they can both tell me their results as well as any advice so I can run the experiment smoother.
     Once I form a conclusion about the hypothesis I made, I can see what makes sense.  If my hypothesis is correct about sleeping and taking a naps, then I can apply this studying habit into my own ways of studying.  If this experiment proves to be beneficial, I can use this way to study during a big test or even during finals week.  I can also tell my friends and peers about this and they can study more effectively.

Unit 8 Reflection

     This unit was all about populations constantly changing and evolution of populations.  Some of the essential themes and understands are evolution, the role of variation in evolution, causes of change, why change occurs, what evolves, and natural selection acting on phenotypes.   One of the major concepts about evolution is that natural selection acts on each individual.  However, this is not the case; the whole population evolves.  The natural selection acts on the phenotypes, but the genotype changes because of this.  Another concept that people miss is that evolution is the change of allele frequency in a population over a period of time.  Going in to this unit, I knew what evolution was but I could not have told you a solid definition.  The concept of evolution can be seen by the Hunger Games Lab.  This lab really helped me understand all of the concepts of evolution in a real example and this lab really cleared things up for me.  The Hunger Game analysis can be viewed here.

     This unit covered most concepts of evolution.  However, there is not enough time to learn everything of one subject.  Some things I wonder about are why evolution is evolution and why natural selection is so random.  Natural selection acts on individuals but I do not understand why it acts the way it is.

     In the previous unit, we learned to be more assertive.  Since then, I have made efforts to try and be more assertive.  One thing I have done that I found really helpful is to stand up like a hawk and not slump my shoulders like a turtle.  I found this to be helpful because standing straight gives me more confidence to become more assertive.  I still need to work on my voice and stating things in a more declarative tone and not in a question-like tone.

Hunger Games Final Analysis Answers

1. In this Hunger Games lab, each student was assigned a different way to eat corks.  There was a stumpy's that had to eat food with wrists, knuckler's that had to eat food with knuckles, and pincher's who had to eat with their index finger and thumb.  The class went outside to the lower field and all stood with their backs to the center and once Mr. Orre blew the whistle, the class would turn around and try to eat as many corks as possible.  After a certain amount of time, he would tell us to stop and count of corks.  If we did not have more than a certain amount, we could not reproduce and died off.  This lab stimulated a real life situation of different kinds of animals fighting for survival.  It also demonstrated natural selection because most of the pincher's survived because they were better suited for survival.
2. The pincher's phenotype of aa was the best for survival.  The pincher's were best suited for survival because the way that they ate was the most efficient.  Instead of picking up one at a time with their wrists, pincher's could grab two at a time with far more accuracy with their fingers.
3. Throughout this lab, the population did evolve and this can be seen with the evidence that I collected.  At the beginning of the lab, the ratio of "A" alleles to "a" alleles were 0.48 to 0.52, respectively.  At the end of the lab, the ratio of "A" alleles to "a" alleles changed to 0.18 to 0.82, respectively.  The population did evolve because the ratio of the different alleles changed.
4. Some random factors in this lab were the assignment of alleles at the start, who stood where in the circle to get food, who was the child of which family, and sometimes the placement of the food.  However, some factors were not random and were done on purpose.  The factors in this lab that are done on purpose are the mating of two individuals and where Mr. Orre decided the place the food in the later generations.  If Mr. Orre decided to put all the food next to the pincher's, the whole population would turn into pincher's fairly quickly.  However, if he decided to help out the stumpy's and put the food right next to all the stumpy's, the stumpy's would have a higher chance of survival and would last a little longer in the population.
5. If the food was a different size, the population would have changed.  If the food was too big for a pincher to pinch, the pincher's would not do as well as the stumpy's because they use their wrists not delicate and precise fingers to grab things.  If the food was smaller, than the pincher's would be favored because they have precise movements and can pick up smaller items easier.
6. If there was no incomplete dominance, then the knuckler's would have not existed and the population would only be pincher's and stumpy's.  The results would have changed because the ratio of alleles would have been far more towards one species and in this case would be the pincher's.
7. Natural selection acts on the population causing the weaker traits to die out and stronger traits to be common.  Over long periods of time, the population would evolve because the population needs to adapt to their environment.
8. Since pincher's provided to be dominant, pincher's commonly got together to mate and produce another pincher baby.  However, later on in the lab, there were only a few stumpy's and knucklers.  The stumpy's bred with stumpy's, making more stumpy babies, which make the ratio of stumpy's in the population higher.  If pincher's mated with only pincher's, the whole and most of the population would be pincher's.  In nature, to ensure survival, same species mate with each other because they want their species to not die out and become extinct.
9. In evolution, a population evolves.  The population would change in order to adapt to what the environment provides.  Natural selection acts on the phenotype.  The genotype changes which causes the phenotype to change.
10. After this lab clearly demonstrated evolution and natural selection, I had a clear understanding of how these concepts work and this lab answered all my questions.

Nap and Studying Testing Progress Report

     For my 20 Time project, I am conducting an experiment to determine how long an ideal nap would be to boost studying efficiency.  The first step of an experiment is to gather data about the topic.  After gathering as much helpful data as I could, I found out a few key things that will help me for my experiment.  I found out about a persons sleep cycle.  Around every three hours, our body repeat a sleep cycle.  If you take a nap and wake up in the deep sleep portion, you will not feel very good.  Another thing I found out was that around a twenty minute nap is ideal because it does not enter deep sleep and the nap does not seem too short.  Over the course of the 20 Time so far, I have learned that I am very curious in my subject.  While I am searching about a particular topic, my mind wanders to compose another question I have about a similar topic.

     So far, I have had a few setbacks.  As of right now, I am about to start my experimental phase.  After gathering enough information and forming a hypothesis, I am ready to conduct an experiment.  However, I need to have a group of people to help me conduct my experiment.  I cannot test myself because I know what is being tested.  I plan to ask my friends that I socialize with outside of class and also ask other biology students in Mr. Orre's class to see if they are interested in joining my experiment.

     My next steps in my 20 Time project is to conduct my experiment.  After successfully running a first round of experiments, I hope to analyze the data and possibly conduct another follow-up experiment to test something related to this topic.  After all the necessary testing is done, I can analyze all my data and come up with a conclusion.  Once I find out what the most efficient nap time is, I can use that information for myself when I am studying for the finals or just studying in general.  I can take efficient nap breaks that can help me get better test grades and also become a more efficient worker.

Unit 7 Reflection

     Unit 7 was all about our ecosystem.  Some big idea of ecology that I learned are homeostasis, interdependence, habitat, niche, biotic factors, and abiotic factors.  Homeostasis is a big thing in an ecosystem because like our bodies, an ecosystem work best at equilibrium.  For example, there cannot be too much of too little sun.  Just right is in the middle where the flowers receive enough energy to produce oxygen and glucose but not too much so where they are out of their tolerance range and die off.  Interdependence is a also a huge factor in an ecosystem.  All the different trophic levels rely on each other to provide food for each other.  The primary consumer all the way up to the quarternary consumer relies on the little primary producer to provide enough energy for them to stay living.  Habitats are important because this is where the species live and perform their daily tasks.  This is where they live and their habitat needs to fit their needs and tolerance range.  Niches are also important because not only does the area need to fit their needs, but the factors also.  The species adaptations are needed to fit whenever something is not going right.  Biotic and abiotic factors are important because a turtle needs other biotic factors such as birds and trees and abiotic factors such as sun and water to survive.  With both of these things working together, the turtle could live.

Our Conservation Biology Project can be viewed here.

     I do have some questions after this unit has ended.  As our unit ended, I wondered about how I could make our home a better place.  After seeing Bag It, I really wonder about how long we can still last keeping up how much we use plastic and fossil fuels to literally destroy our planet.  Also, I want to know how I could help.  This task seems way to large of a problem to understand what little role I could do to help contribute to solving this problem.

     I think that our Conservation Biologist Project went really well.  My group had a really easy time dividing the tasks equally and meeting deadlines.  Our group did not have any communication errors or conflicts that stopped our progress on working on our project.  I think that the way we divided work went well because we finished everything in a timely manner and everybody knew what to do.  However, I thought that we did not have time to record the project together, so Mitra had to finish it at home.  I learned a lot about how a group project works and I can take my knowledge to apply it to the next project so it runs smoother.  For my survey, I was a little more passive than aggressive but my assertive score was not very low.  A few things that I can do to become more assertive is to stand straight like a hawk not a turtle.  I need to stand up straight and also look people in the eye.  If I think that staring into each others eyes are weird, I can look at their nose of forehead.

Story of Stuff Extra Credit Summary

In this short informational video, I learned more about the process of how to change the process.  From the last video “Story of Stuff”, I learned about what five things contribute into the cycle of burning fossil fuels to creating hazardous toxins.  The video “Story of Change” was a continuation of the previous video.  “Story of Change” talked about how we can change this system.  The answer to changing the system lays in our hands.  We the people have the ability to change the whole system.  There are three different components to changing the process.  The first step is the idea.  Everybody needs to have an idea to start and build off of.  For example, Martin Luther King Jr. needed to have an idea of what he wanted to argue before he could do anything.  He couldn’t just go up there not knowing what he wanted to say.  The second thing is we the people.  We live in a democratic society and we the people have a huge amount of power.  For example, when Martin Luther King Jr. was giving his speech, only 25% of the people supported him.  This may seem like a tiny amount, but that 25% of the people were highly effective.  The third thing is to take action.  The 25% of Martin Luther King Jr.’s supporters did not just stand around waiting for something to happen.  Those 25% of the people took action and made something happen.  This step is very critical because if you have all three things, you can change anything you want.  I think this three step process is very logical and effective.  First, you need an idea.  This makes sense because you need to know what you want.  The second step is we the people.  This means that the citizens have the power to protest and eventually get what they want.  This makes sense because the majority of the population of America is the citizens, not the wealthy.  The third step is to take action.  This makes sense because an idea is only just an idea unless you do something about that idea.  Someone needs to make it happen or else nobody would know about the amazing idea.
