inner fish relate and review

After watching "Your Inner Fish" i began to better understand the connection between us and all other life forms. Not only did we watch that, but we also watched "Your Inner Reptile". These videos explained to me how all living things have connections. Whether its a fish, or a reptile, there are traces of ancestry and things that relate us to them. In embryo form, all living organisms look almost identical, with only minor characteristics to tell us apart.  Over millions of years they claimed, that we formed from the organisms. We are related to fish and reptiles the film said, and the way we form and the different bones in our body are related. These movie relate to the last unit we learned about, and how evolution has changed different species to help them adapt to better survive in this world. We can tie the film into the same category or unit because it helps teach us about how we were all embryos and basically the same, but evolution has changed each species and created differences between us. I can also now use what i learned in this video for the future units. I will be able to know how we all formed and that we all have a common ancestor. The information that i have absorbed from this film should also help me on the upcoming test that has information on evolution and adaption.

Invertebrates: The Cuddle fish

The Cuddle Fish or Sepiida! I'm doing my blog post on the cuddle fish because its a very unique invertebrate with many different features that are appealing to my interests. The cuddle fish is a species closely related to the squid and octopus families, in the Molluska invertebrate group. They have long stretched out bodies and a series of tentacles around their mouths. My favorite adaption that the cuddle fish has adapted is its ability to change color. The skin of the fish will change or often flash color pigments rapidly during fighting to scare off the contestant, or during mating to attract a member of the opposite sex. Just like their relatives, the cuddle fish contains a small sack witch it uses to discrete an inky liquid in times of danger to allow the fish a moment to flee from the scene. The cuddle fish comes in many different sizes, from just 15 Cm to sometimes half a meter in length! It is a real excitement to watch this cuddle fish eat its food. They are primarily carnivores, feeding on crabs, other crustaceans and sometimes small fish. They cuddle fish grabs the prey item in its tentacles and bites down on it using a hard beak that is hidden within. Cuddle fish are known all over the world and are known to live in any type of environment, from shallow warm tropics to cold deep ocean floors this animal thrives. This really is a magnificent invertebrate that still finds ways to shock the world and amaze scientists. Below are some pictures of cuddle fish and a chart helping better describe this animal and give a better idea of what the cuddle fish really is.

3rd Blog Post

The last 3 weeks of working on my 20 time project went great! I was able to better further my interest and gain more information about channelization. I have finaly come up with a solution to fix the problem of channelization. I propose that we as people can eliminate all concrete channelization from local streams of rivers and then plant native plants in their place, so the river can take control and make its own path. Slowly but surely, overtime the rivers and streams will be good as new. I learned more about how channelization is affecting the animal populations because it is destroying their habitat, and I also began to see how I am good at thinking through problems and coming up with solutions, especially involving animals or the environment. I had no major setbacks during these 3 weeks. I felt I worked quite efficiently and finish what I set out to do by 3 weeks. I will now create a diagram or repusentation to show the class how channelization affects the environment, then pitch my idea and see how they react. I can use these learning methods in class to help me better come up with solutions to problems.

Unit 8 Reflection

Unit 8 was all about change, and how organisms and the world have changed. We started off this unit with multiple vodcasts to get our minds wrapped around the idea of change over time and natural selection. We then did two labs to demon strait natural selection, and how only the species willing to change and adapt will survive. The first lab we did was the "bird beak lab"; in this lab each group member was given a utensil to use as a "bird beak". We all had a certain amount of time to pick up as much food as we can with the beaks, and get a good idea of how natural selection can really affect a population. The second lab that we did as a class was the "Hunger Games Lab". This lab had the same idea as the other lab; to teach us more about natural selection and change over time. Both these labs demonstrated to us the importance of natural selection. I can use the information that i have learned today in the future because i look forward to having a job that includes working with exotic animals. By knowing how these things work, i will better understand how they have changed overtime, and what contributed to their change. This unit was very informing and helped better further my knowledge.

Geologic timeline individual reflection

The earth has gone through so many phases and stages. Some major events in earths history are the big bang theory, the extinction of the dinosaurs' and the Proterozoic eon, the largest period in the earths history timeline. The bib bang was probably the most important time in history because from this the moon was formed. if the moon wasn't formed then the earth wouldn't b able to function how it does. The extinction of the Jurassic period was in my book a big historical event. Everyone knows about the dinosaurs and knows how they were killed by an asteroid that collided into the earth. Finally the Proterozoic eon was very important because it was the longest period in the worlds history! While exploring the earths history I was surprised to see how the continents moved drastically and how many extinctions there were. After each major period in earths history, there was an extinction of the population. During our time on earth we have affected the climate so drastically from population to the destruction of forests and habitat for other animals. I believe that if we keep up with our habits, then the world will soon become a wasteland, and we will no longer be able to live within its atmosphere safely. We humans need to figure out permanent ways to help decline the amount of pollution and destruction of the land. The only question I have is what can we do to help save our world?

2nd Blog Post

My 20 time project of how channelizing rivers is affecting the wildlife populations that would be living within that environment, and how we should find a way to create a better niche for the organisms living there. I spoke with my science teacher Mr. Orre on this topic and was able to better understand

Hunger Games Final Analysis

1. In the hunger games lab, we the class separated evenly into 3 groups, the stumpys, the knucklers and the pinchers. These three groups acted as subspecies of an over all population. The point of this lab was to show how natural selection and evolution work. The 3 different groups would hunt for food and then tally it to see how many offspring each person would have. Those people from the group with the best adaptions would survive.

2. Pinchers had the best phenotype for capturing food because they could use two hands, they had a large mouth size and they could pick up food the quickest.

3. yes. The overall population did evolve. Before the battle for survival began there was a total population of 21 individuals, but as the years went on the population began to decrease to a low of 13 individuals. The years that followed that the population size was able to reach a stable population of 18 individuals.

4. Some random affects in this lab were where and how the food was scattered. The food wasn't always put where it would be easiest to get. The non random parts of this lab were the type of food we were getting and the number of individuals in each group.

5. If the food was bigger or smaller the outcome of this lab would be most definitely different. If the food was larger it would be a lot harder for the knucklers to pick it up and gather food, but the stumpys would have an easy time grabbing the bigger pieces of food. If the food was small both the knucklers and pinchers would thrive while the stumpys would die.

6. yes. If there was not incomplete dominance, then the outcome of this lab would be different. If no single group had an advantage over the others, then all groups would have a similar number of babies and the population would stay steady.

7. Natural selection is the backbone of Evolution. When natural selection begins to knock out the bad alleles and traits of a species, then the species begins to evolve.

8. Some individuals or groups would "cheat" in this lab. They would collect food using a different method in order to survive. By doing this, the allele frequency would change because the population with the cheaters would grow. The alleles from the winners would be passed on.

9. The species as a whole evolves in evolution. In evolution both the genotype and the phenotype change, to better give that species an advantage to survive.

10. none
