pig dissection lab p4 g4

I beleive the main perpous of this lab was to help us under stand how the body works and how all of it's internal and external organs work. The dissection cam be related to how we learned about all of the body's systems like the immune system, and the digestive system. I did not enjoy one signal part of this lad at all because seeing the insides of that pig was the disgusting thing I have ever seen. I bevies that this was one of the most unpleasant thing I had to experience.

20 time final blog post

The wind jet MK 10 was one of the best things i ever did, but it is time to conclude my 20 time project. If you missed what my project was about click here. Also joy the video of our presentation

20 time reflection

I challenged myself by creating a new windmill. I chose this challenge because i wanted to help create a way to make more energy for the economy. I had to improve my design many times and i did reequip help form my partner Elise. With our new windmill design the wind jet MK 10 it will produce more energy at a faster rate. So far it is going very well we have had problems with designs and where we would place it, but they were fixed quickly. Right now i am organizing our info on a google slides. I learned how the wind is used to create energy for cites and towns. I i had the chances to do this problem again i would test all of my wind mill designs to see what worked and what failed. Next i will be making a the scripted on what we are going to say for the TED talk.

unit 9 reflecion

This unite was mostly about how life on earth evolved to what it is today. Some of the essential understandings were how and why things evolved foe example Many years ago whales used to be predators, have legs, and could walk on land. Another example is How we classify organisms based on there evolution. This is also shown in well detail in my what on earth evolved presentation. During my presentation i spoke nice and slow  so i thought it went well. I could have memorized it more because I looked down at my google slides a little. In the future we are going to be doing a ted talk and i can use my skills i used in this presentation to show the class all about it.

I want to learn "how long did it take for fish to evolve legs?". I also want to learn" What dose the common ancestor of all organisms looks like?". The one unanswered question is "Why did humans evolved to become the dominant race?".I wonder if something could have evolved to become the dominant race on Earth.

the fish that lives inside us all

After watching the movie "Your inner fish" i have come to understand how we are all related to fish. Because all living thing did come form fish who crawled on land, it is natural to think that we have a common ancestry with fish. During this video We follow a scientist on a journey to fined out how we are related to fish, he studied Fossils, worked at dig sites, and compare human and fish bones. First he looked for the traits that fish made to become mammals. Then he looked for the traits that made mammals into humans. One of the questions were should focus on is "What is one defining piece of human anatomy that seems remote from fish?  How did scientists show that this piece of human anatomy has its origin in ancestral fish?" . Because fish were the fist animals to have a internal skeletal system. Another question we should focus on is "1.      Even though we don’t look much like fish what are some things that we have in common with fish?  How does this give evidence for common ancestry?". because fish and humans both have teeth, back bones, a stomach, etc. this all shows how close we are to fish. 

Windjet MK 10 update

During my research we have learned how wink mills are build and how they collect energy. We have also learned that we are great at gathering and organizing info. So far we have not had any setbacks and we are handling really well. Our next step is to finish organizing our info and make it into a speech. I can use what I have learned to help our community get more energy with the wind jet MK 10.

sea sponge blog post

A sea sponge is The world's most simplest multi-cellular organisms. The sponge's classification is "Porifera' which literally means "pore-bearing," and refers to the numerous little openings seen on all sponges. Sponges can grow into many different shapes, sizes, and colors. There is over 5,000 different kinds of sponges in the ocean. The first thing i learned about sponges id that they suck water in that shoot it out of the top, and any plankton that gets sucked in don't come out. The second thing I learned about was that they are animal and not plants. The third thing I learned about was that Sea Sponges have few predators other than sea turtles, and fish because some produce toxins. The final thing I learned was  Some deep-water sponges can live to be over 200 years old. I can relate this to the vodcast on invertebrates. I can also relate this to earth science in middle school.

unit 8 reflection

During this unit we went into a deep description about evolution and how it effects different organisms. The main theme for this unit was about how we have evolve and how little time we have existed in Earths history. I have learned a lot of info about evolution like how birds developed specials beaks to get food in the bird beak lab. I have also learned that the birds with better beaks can reproduces and pass on their traits to their offspring in the hunger games lab. But out of all I learned how there was nothing more interesting Then in the Geographic Time line lab when I found out how old the earth really is. One of my unanswered questions is "Why was the Earth formed in the first please?" Another unanswered question is "How do we know the universe formed this way?" One of the things I wonder about is Why I don't have a pet tyrannosaurus Rex. After the movie I decided to be more opened minded and I will work on being more loss and less serious.

time line reflection

One of the major events in earths history was the first land plant, this was very important because is showed the first signs of life on land. A second major event in earth's history was the time of the dinosaurs, this was very important because it was  a time of massive biodiversity. Another major even was the ice age, this was important because this was when the world was covered in ice. the scale of earth history is bigger than the planet itself, and what real surprised me was how old the world is. To me its mind blowing that the amount of time we have been on earth is century's compared to use, but it is only a small fraction of the earth history. I only have one question"Why was the Earth made in the first place?"

Coming soon the windjet MK 10

During our 20 time me and Elias have relived that making a new wind mill design isn't as easy as we thought it would be. We have also learn about our self's, witch is that Elias is great at finding info and I am good at putting it together. We have had many setback on trying to find the right design for our project. We were able to handle it very well when we made the wind jet MK 10. Next Elias will find info on the resent windmill design and I will organized so that we can use it to benefit our design. Our project will help our community produce more energy from the wind.

hunger games lad conclusion

1.  In this lab we birds with different beaks trying to survive and reproduces. We were trying to simulate natural selection
2. The phenotype that was best at capturing food was the pinchers because we had the highest population in the end
3. The population of mostly evolved in to Pinchers. This happened because Most of the Pinchers survived and were able to reproduce.
4. In this lab the food placement was random, what was not random was the feeding area.
5. I believe that if the food was larger or smaller it would have made a difference. It would have probably given the stumpys a better chance at surviving. I can relate this to how an ecosystem can loss food sources as easily as it gains food sources.
6. Yes there would be a change if there was not incomplete dominance because the stumpys would not have died.
7. the relationship between Natural selection and evolution is that we were able to mate freely and our offspring was given a new trait or the trait of a different birds. 
8. The groups adapted the ability to collect large amounts of food to survive. The species that had the most food would have gotten to pass down their alleles to their offspring. i can relate this to how Squeals collect food for the winter to ensurer there survival.
9. In evolution the alleles of the population change so that the population can survive. Natural selection acts as a phenotype because it pass alleles from perent to offspring.
10. Pic of the graph is at the top

bird beak lab analyses

1.These 2 graphs show how much food i got and how many offspring i had.

2. My fits hypothesis was "If my offspring have a tweezers beak then they will survive" my evidence is that the tweezers beak was able to pick up most of the food. my second hypothesis " If the population have tweezers beak then we will survive" my evidence is that the tweezers beak allows the population to feed more.

3. I believe the the tweezers beak will help you survive because it can easy pic up food. The more food you get the higher your chances are to survive.

new windmill design 1st post by chirs and elias

20% time is when a teacher give 20% of class time to his or hers student to work on a project of his or hers choosing. Our essential question is how do you making windmills more efficient and produce more energy? For our 20 time we decided to make a new windmill design that would obtain more energy in any kind of wind speed. We did this because it will make sure no one wastes energy. Our design shows how it collects more energy than the average windmill. Our goal is to create new windmill design that creates more energy than the average windmill. For the progress/achievements we have right now is one design but no information on it. We plan on making a blue print of our design that shows all information about it.

unit 7 reflection

This unit was all about ecology the study of organisms and how they entrant with their environment. The main theme of this unite was what effects an environment positively and negatively. I want to learn more ways that we can help save the environment. I also want to learn how pollution effects the organisms in an environment. One unanswered question i have is "Why do people litter so much when they know it is dangerous for the environment?" Another unanswered question i have is "How long do we have before we destroy our own planet with pollution?" The first thing i wounder about is how many land fills and garbage dumps do we have. The second thing i wounder is how mad is the garbage at sea and how is it effecting the sea life. During our conservation biologist project we had so things that went well and some thing that didn't went well. What went well for us was the drawing and filming. What didn't went well was putting and editing the move together. During this project i learned how the arctic is being threaded by global warming and how it effects the animals. I also learned how we can stop global warming and save the arctic. The collaboration went well we did have some problems but it work out well in the end.

unit 6 reflection

This unite was mainly about the biotech witch is the study and manipulation of living things(including their molecules, cells, tissues, or organs) in order to benefit mankind. the main theme was to see how cell, bacteria, and proteins react when added plasmid to them, witch could drastically change them sometimes in a good way but some times in a bad way. One of my set backs was trying to understand all of the fields of study that biotech can go with. Another thing that was a set back for me was writing down notes during the pGLO vodcast. One of my successes was being able to please the dye in the well of the gel. Another one of my successes was being able to make bacteria glow.

first we did the recombinant DNA lab. in this lab we learned how DNA is extracted by a restriction enzyme, then is added to a plasmid with a cut that can allow the DNA strand to fit in it. The second lab was the candy electrophoresis lab. in this lab we extracted the dye from candy and see if was the right color by putting it through the gel. the last lab we did was the pGLO lab. in this lab we added plasmids to bacteria to see if it would  make it glows.

there is some things I want to learn about like if adding a plasmid to bacteria can cause the bacteria to die, and can plasmids help cure despises. One of my unanswered questions id who discovered biotech? another is how many things can biotech contribute to? I am also wondering if biotech will continue to expand its field of study.

I have inproved on my goals a lot. I have been working out harder in PE, and also have tried harder to meet my minimum standers. I will continue to work hard in PE and will never stop in tell I reach my goals. I also have improved on my studying methods for tests and quizzes. I will continue to practice new studying methods in tell find one that suites me.

pGLO lab

pGLO Observations , Data Recording & Analysis

1.

Obtain your team plates.  Observe your set of  “+pGLO” plates under room light and with UV light.  Record numbers of colonies and color of colonies. Fill in the table below. Plate Number of Colonies Color of colonies under room light Color of colonies under   UV light - pGLO LB 0 no color no color  - pGLO LB/amp 0 no color no color + pGLO LB/amp 1,000 peach color peach color + pGLO LB/amp/ara 100,000 peach color florescent green

2.	What two new traits do your transformed bacteria have?
	they have bigger colony's and one of them can glow
3.	Estimate how many bacteria were in the 100 uL of bacteria that you spread on each plate. Explain your logic.
	I estimate about 100-200 in each one because bacteria are about the size of a cell
4.	What is the role of arabinose in the plates?
	it allows the bacteria to grow under UV lights.
5.	List and briefly explain three current uses for GFP (green fluorescent protein) in research or applied science.
	Fusion tag: observes the activity of the protein
	active indicator: see how proteins change to its environment
	in FERT: to observe the energy transfer
6.	Give an example of another application of genetic engineering.

to see if GFP have any effects an animals.

candy elecrophoresis lab

From the pictures below you can see that some dyes do separated over time like the blue and dark red dyes. Also the dyes did not change colors will moving. I believe that the Betanin (beetroot red) is a structure of one of the dyes we used in our lab because it looks like the dark red dye on the far right. Dog food manufacturers put artificial food colors in dog food because it might help keep the dog healthy. the two factors that control the distance of the colored dye solution migrate are the negative and positive charges in the gel, and it also helps them move through the gel. the electrical charge causes molecules to move depending on their charge and the gel slows down bigger molecules relative to smaller molecules. they will separate from smallest to biggest with the smallest being farther ahead than the biggest.

recombinant DNA lab conclution

first thing you do is, you locate the gene of interest, witch is then location and sequence of the gene including above and below in the bacteria. Second thing you do is, use the restricted enzymes to get the gene out, a restricted enzymes are enzymes that cut DNA whenever it reads a specific sequence. we used was Hin dIII because it is the only one that worked. Third thing you do is, you cut the plasmid  in one place that matches the restricted enzyme, be sure not to cut the plasmid in two please or the DNA that is going in will not fit. Fourth thing you do is cut two places that match the restricted enzymes in the DNA and take that cut off peace put it in between the cut in the plasmid. fifth thing you should do is, you let the ligase attach the two bases together. sixth thing you should does, use antibiotics to see if the plasmid has been taken into the host cell, but antibiotics as tetracycline, kanamycin, and ampicillin normally kill the host bacteria. This process is important to life because it can help cure deceases or  help insulin genes. Recomdinant DNA can be use for helping bacteria that is healthy for the body.

second semester goals

There are two major SMART goals that i want to accomplish for this semester. one SMART goal is to change the way I study for tests, quiz's, and exams. I will review my vodcast or talk to my teacher for any thing I am confused on and I will also review the check for understanding quiz's. 2 days before the test I will quiz myself. This might improve my skills for studying. It is important that I work on my studying skills because it will help me do better on tests. I plan on doing 30 mins for studying when I find out about a upcoming test. Another one of my SMART goals is to do better in PE. I will go to the gym every weekend and during the breaks. I will work on my muscles so i can do better on meting my minimum standards. I believe that this will improve my performance and my grade in PE. I will spend 30 to 45 mins at the gym when ever i have time to do so.
