http://en.wikipedia.org/wiki/File:Galapagos_giant_tortoise_Geochelone_elephantopus.jpg
The giant tortoise can live up to 175 years.
The giant tortoise can go a year without food.
A giant tortoise sleeps up to 16 hrs. a day.
The Galapagos Islands are special because of where they are and what lives there. They are in the middle of the colliding warm and cold water currents. They are home to marine iguanas, the only sea species of iguana in the world. The waved albatross needs the Galapagos Islands to have a place to breed.Sea lions also migrated there. This is the home to penguins.

Guppy Simulation
1) To attract mates.
2) Guppy or Millions fish
scientific name: Poecilia Reticulate
from Brazil
size: 1.9"
metallic silver in color, blackish blue tail and fins

size: 1.9"
metallic silver in color, blackish blue tail and fins
3) Tigerfish
scientific name: Hoplias Malabrsacus
up to 24"
from Trinidad
sandy brown in color
scientific name: Hoplias Malabrsacus
up to 24"
from Trinidad
sandy brown in color
4) The size of the body of water and the size of the predator fish.
5) John Endler is a biologist that studied guppies in Trinidad.
6) Pool1: Very bright with large spots
Pool2: Medium coloration with medium spots
Pool3: Very drab in color
Pool2: Medium coloration with medium spots
Pool3: Very drab in color
7) Higher in the stream there are few predators so that they are able to be colorful and the lower you get the drabber you get.
% of Brightest Guppies | % of Bright Guppies (10 generations) | % of Drab Guppies (10 generations) | % of Drabbest Guppies (10 generations) | |
Trial 1 Guppy: Even Mix | 61% | 29% | 10% | 0% |
Trial 2 Guppy: Even Mix | 13% | 77% | 11% | 0% |
Trial 3 Guppy: Even Mix | 3% | 4% | 6% | 87% |
Trial 4 Guppy: Mostly Bright | 65% | 24% | 7% | 4% |
Trial 5 Guppy: Mostly Drab | 0% | 0% | 0% | 100% |
8) They eat the easiest to see fish and so the fish become drabber to survive.
9) 1:My hypothesis was correct, less predators=brighter colors.
2: No, my hypothesis was wring because the brighter guppies survived.
3: My hyppothesis was correct because the drabbest survived and the brightest died out.
4: My hypothesis was correct there were few predators and the brightest survived.
5: My hypothesis was correct, with lots of predators, only the drabbest guppies survived.
2: No, my hypothesis was wring because the brighter guppies survived.
3: My hyppothesis was correct because the drabbest survived and the brightest died out.
4: My hypothesis was correct there were few predators and the brightest survived.
5: My hypothesis was correct, with lots of predators, only the drabbest guppies survived.
10) The males are conspicuous to predators and easier to spot by everyone.
11) There are fewer predators higher in the stream allowing the males to be brighter in coloration.
12) They would die out because the brighter guppies get mates.
13) They would die because the predators can see him better.

Biodiversity
1) Okay, say that you switch to recycling, then the amount of waste dumped in the ocean and landfills of the world.
2) If an species with healing properties that we have not yet utilized could die and then we would not know what we could have healed with those properties or an animal like bees could stop moving pollen and the plants and animals that feed on them will die.
3) If we conserve the number of different species on Earth, then we could learn of a new cure for say cancer or AIDS and we would have a larger food source.

Gasses and climate change
Combustion
Hypothesis: The combustion will produce flame and soot but nothing else.
The combustion created a sound like a whoosh and flames flew into and out of the bottle.
The human race is creating chemicals that a not supposed to be int eh atmosphere by using combustion.
CO2
Hypothesis: The flame will create a sound and soot.
The CO2 killed the flame.
Hydrogen
Hypothesis: There will be no flame.
The chemical reaction from Zinc and the acid was fizzy.
The flame created a boom and a flame that eventually dissipated and bubbled the liquid.
There are many fuel sources that the humans do not use like tidal power and geothermal energy, these are powerful and could work as renewable resources, also scientists believe that in 2025 the world will be at Peak Oil which means that almost half of the Earth's oil that can be extracted will be extracted.
Air Pressure
Hypothesis: When she puts the can into the ice bath, the can and vapor will freeze because of the change in air pressure.
When she put the can into the ice bath nothing special happened.
Hypothesis 2: When she puts the can that is sideways is the vapor will turn to ice.
The rapid change in air pressure crushed the can. The inverted can also took in some water and replaced the vapor in the can.
The air pressure is changing and affecting temperatures and other weather like increases of rain in Scotland, reduced rain in Spain, and a drop in the number of cold snaps in France.
Winters will be warmer, wetter, and windier in Europe due to changes in air pressure.
The winters will get milder in Canada and the U.S.

Chornobyl questions
1) Why did they have to do the tests?
2) Why were the scientists not informed that the reactor was unstable at the time?
3) Why was this not prevented?
4) Why was this not prevented?
5) Why did they put soldiers at risk after the explosion by putting them on guards?

Panel Questions
1) What has been done to stop the chemicals from leaking into our water like they did in the 50's?
2) What measures have been taken to stop the spread of the chemicals today?
3) Is there proof supporting your viewpoint?
4) What exactly did the Superfund project do to prevent animals from coming in contact with the chemicals?
5) Is there proof that there are still toxins in the canal?

8-30-10 catalyst
1) The blizzard of '77 along with the early spring and melting. This caused the overflow of water and toxic chemicals to then rise to the surface of the first cap that was installed by Hooker chemical.
2) Most of the chemicals dumped there were linked to cancer. There were also birth defects and miscarriages.
3) The underground animals like moles and groundhogs can die by going to this place. The predatory animals were also hurt because if they ate things like moles they could die because of no food in the area.
