Hot Turtles

1) Climate Change
Our earth has warming.  over the past century our Earths temperature has risen 1.4 degrees F. and is still warming up this very moment.  When the climate of the Earth changes everything is affected.  everything living on this earth has adapted to the earth and its original form.  when climates change humans and other organisms aren't prepared to live in those conditions which causes them to have serious problems.  People are the main reason for climate change.  Humans can produce bad carbons and gases that get traped in the earth and make a blanket which blocks out what we need.  this affects us all.


2) Amazon Turtles
When turtles lay their eggs the temperature of the sand determines the whether the turtle will be male or female.  when the sand is hotter the baby turtle will be female and if its a colder temperature the baby turtles will be male.  the concern that turtles face when dealing with temperature is if the climate changes and increase there could be a risk of all the turtles becoming female which means there would be no possible way to pro create.  which would adventully mean the turtle would die off. turtle play a major role in the world turtles eat plants and berries and the when they poop the seeds from the plants land and re plant.


3) what can we do
Well we know turtles lay their eggs on the sand and the temperature determine the gender of the new turtle.  if we are worried all the turtles will be born female, we should dig up some of the eggs and relocate them to a much cooler area or an incubater that keeps the eggs cooler.

protecting marine life

What role does the marine wildlife and nature play in your life?


Marine life plays a big role in my life and all humans. marine life can provide us with food and resources like water and things that come from the sea. humans depend a  need on the wild life. we depend on it to survive. 


How does the use of marine resources impact you on a personal level?
 on a personal level I feel the impact we have on marine life is not good. we kill a lot of marine life and hurt and damage a lot of marine life for our personal needs.  I understand that we need marine life to survive but we should only take as much as we need and not take more and kill marine life that we don't  need or use.  such as over fishing. 


Specifically, what new thoughts do you have about marine resources and the way they are used by people?
I believe having marine resources is good. it helps people survive and communities grow but at the same time I feel they are only good when we treat the marine life good and do not abuse or power. 


what Code of Ethics will you take to protect marine resources both now and in the future?
 a code of ethics i show is bye not going to sea world. finding out how sea world treats its whales is horrifying.. whales belong in the wild and not trapped in a bath tub their whole life.  the whale are not fed and abused by other whales making the whales emotionally distraught.  sea world is not a good place and i will not be going there

Project

This past Thursday I did not go on the field trip.  I worked on my project. 


Coral bleaching:
 my project was all on coral bleaching.  I learned how coral can become stressed and lose all of its color.  when coral loses its color it dies which effects all of marine life.  coral is the home to many organisms and with out coral all marine life will suffer.
    the way I found out all about this information is by researching the web and using multiple sources.  I really liked this project a lot and I enjoyed picking a topic of my pleasing.  coral bleaching is something that really interests me because I love coral.  I think coral is stunning and with my research I found that humans are one of the giant reasons coral becomes stressed. 
   we need to try to prevent bleaching because it harms more then just coral. and when all marine life suffers we all suffer.

Aquarium Field Trip

New England Aquarium

In the New England Aquarium I really took some time to observe the Leidys Jellyfish.  they were little jellyfish and they lived in dark water where they would light up due to electric flow going through them.  the electricity made the jellies light up rainbow. the jellies would float around and bump off of each other sometimes latching on to one an other. 
   the aquarium was filled with many cool organisms from penguins, fish, sharks, eels and more.  one part of the aquarium that I really enjoyed was the shark and ray tank.  there was one ray who would come up to my hand every time and try swimming up my arm while sucking on my skin.  the rays were soft and slimy in touch.  their stomachs shouldn't be touched because the stomachs are very sensitive in comparisons the top of them. 
  Another cool thing about the aquarium I saw was the giant fish tank in the middle of the aquarium that was filled with all sorts of organisms.  one animal was myrtle the sea turtle.  she was 85 yrs old and still living. they also had a turtle named Carolina.
   over all I thought the aquarium was a fun and educational field trip.  I learned a lot about marine life and how we need to protect it.  I also thought the movie was awesome! I learned a lot about saving coral reefs and it also made me want to travel.

Here is a picture of a ray just like the ones in the touch tank!

seaweed web quest

Here is a picture of seaweed under water.

Pre-Lab: Diversity of Algae and Seaweed Questions:

Why are seaweeds assigned to the Protista rather than Plantae?

They aren't  plants because they don't have a vascular system like regular plants have.

List, describe, and state the function of the four basic parts of a seaweed. Also, state the name for the entire seaweed body. 

The stalk or stem of a seaweed is called a stipe and its main function is to support the rest of the plant. Blades function is to provide a large surface area for the absorption of sunlight. Holdfasts, attach them to the sea floor. Floats or pneumatocysts help to keep the photosynthetic structures of the seaweed buoyant so they are able to absorb energy from the sun.

What are the most important ecological roles filled by seaweeds?

They provide shelter for other organisms and they are also a source of food for other organisms.

List several types of environmental stress seaweeds encounter.

seaweeds can have stress by many things.  one they can be exposed to the weather and air.  also changes in temperature in the water can cause stress along with the constant motions of the water.

Briefly describe sexual and asexual reproduction in seaweed.

They  reproduce asexually through fragmentation or division.Seaweeds can reproduce sexually, by the joining of specialized male and female reproductive cells, called gametes. 

Upon what characteristic are seaweeds classified?

The red algae , the green algae , and the brown algae .

1) What are diatoms?

Diatoms are photosynthesizing algae

a) Explain the role of diatoms in the carbon cycle.

They reduce the amount of CO2 in the air during photosynthesis.

b) What are the major characteristics of diatoms?

 Diatoms are unicellular eukaryotes that are microscopic in appearance. For the most part, they are photosynthetic micro-organisms, although some may live heterotrophically

c) Describe the life cycle of a diatom. 

When a cell divides each new cell takes as its epitheca a valve of the parent frustule, and within ten to twenty minutes builds its own hypotheca; this process may occur between one and eight times per day.

d) List five human uses for diatoms. 

 clean the human colin, reduce one's weight, lowers cholesterol, reduce high blood pressure, and finally strengthens hair, nails, gums, and teeth.

e) To what division and class diatoms assigned?

Division Chrysophyta, Class Bacillariophyceae

Algae Type	Brown	Green	Red
Division	Phaeophyta	Chlorophyta	Rhodophyta
Specific Example	Egregia menziesii	Codium fragile	Chondracanthus exasperatus

Habitat(s)	intertidal zone,	intertidal zones	Deep water
Human Uses	food, cosmetics, pharmaceuticals fertilizer	food	toothpaste
Useful Substances	food and medicinal use	lettuce	toothpaste, canned meats

Photosynthesis Lab

   Photosynthesis is a process used by plants and other organisms to convert light into energy, and nutrients. The chemical equation is 6CO₂ + 6H₂O ------> C₆H₁₂O₆ + 6O_2.  In this lab we took  spruce and placed it in to water. We then put baking soda into the tube with the plant, and placed this under the light. We then watched the test tube for signs of photosynthesis. When the water began to bubble  this showed photosynthesis. The more light we had and the longer the water was under light the more bubbles, meaning more photosynthesis. We then added phenol red to the test tube and covered it with tinfoil. Then we inserted a straw and blew into the straw and the solution turned yellow because of the carbon dioxide in the oxygen. though when the test tube was left in the dark it turned back to red. 

Here is a picture of the process of photosynthesis 

Geographical TimeLine

Geographical Timeline:


During this learning activity the skills and knowledge that was gained was being able to learn about different time periods.  i gained a lot of knowledge on each time period and characteristics about each of them.  i also learned the orders in which the periods went.
  During this project i contributed to many things.  i made the index cards for both of out time periods, which were permian and Triassic.  that involved digging up information and researching the periods.  i also drew the picture for the Permian time period.  other work i did was i wrote 150 words on the Triassic time period.  Along with that i made the clay fossil and a silohette.  doing all these things allowed me to gain more knowledge and learn more about the permian and triassic periods.
    what i gained from others in this project was information from the time periods they were assigned.    by everyone going up and talking about their period helped me learn about the other periods besides my own.
   Finally i think group collaboration went well and we all talked well in such a way the the others would gain knowledge about our period of time
