Animal Adaptation

seun267 — Mon, 06 Apr 2009 11:45:03 +0000

All animals live in habitats, Habitats provide food, water, and shelter which animals need to survive, but there is more to survival than just the habitat. Animals also depend on their physical features to help them obtain food, keep safe, build homes, withstand weather, and attract mates. These physical features are called called physical adaptations. Physical adaptations do not develop during an animal’s life but over many generations. The shape of a bird’s beak, the number of fingers, color of the fur, the thickness or thinness of the fur, the shape of the nose or ears are all examples of physical adaptations which help different animals to survive.

Climate Change

Two Topics in Climate Change Forests and Adaptation.

Forests:

The effects of climate change on forests in the U.S. and other parts of the world will depend not only on climatic factors but also on stresses from pollution like acid rain.

Climate change effects that influence tree growth will also alter rates of carbon storage or sequestration in trees and soils. Increased carbon sequestration would remove CO2 from the atmosphere this is a negative feedback that lessens climate change, whereas carbon losses through forest disturbances would result in CO2 entering the atmosphere which, is a positive feedback that strengthens climate change.

Changes in forest could bring such as fire or disease, could also affect the future of U.S. forests and the market for forest products, such as timber. Increased temperatures could increase fire risk in areas that become drier due to climate change.

Adaptation:

The Planet is changing rapidly and its kind of our fault. So to protect out selves from this we have to adapt. Which is the cause for adaptation. Basically what this means is that once you have experienced something bad we have a way of stopping that thing so it wont happen again. This is what it means to adapt.

The extent of climate change impacts upon different ecosystems, regions and sectors of the economy will depend not only on the sensitivity of those systems to climate change, but also on the systems’ ability to adapt to climate change.

Greenhouse Gas

seun267 — Wed, 04 Mar 2009 14:00:42 +0000

What does greenhouse gas do to affect our environment?

Greenhouse gas affects the environment because it creates droughts and takes away from the environment making it worse and eventually it not going to be usable anymore.

What is greenhouse gas?

Is it harmful to us and the environment?

Fears are that if people keep producing such gases at increasing rates, the results will be negative in nature, such as more severe floods and droughts, increasing prevalence of insects, sea levels rising, and Earth’s precipitation may be redistributed. so it is harmful to us and the environment.

What is the greenhouse effect?

The greenhouse effect is when infrared radiation is absorbed by “greenhouse gases” such as water vapor, carbon dioxide, ozone and methane, which slows its escape from the atmosphere.

Are we the cause of green house gas or has it always been here?

Yes we are the cause because The problems begin when human activities distort and accelerate the natural process by creating more greenhouse gases in the atmosphere than are necessary to warm the planet to an ideal temperature.

Energy Project

seun267 — Fri, 06 Feb 2009 01:39:30 +0000

A video we can do about the 1st law of thermodynamics can be about something that has energy and that energy can’t be destroyed. Like an hour glass. We can use an object that already has a set amount of energy in it. Like a can of unopened soda or a battle with liquid in it. For the 2nd law we can use something like a generator that uses more energy that it generates. The video can be about measurig how much electricity the generator makes compared to how much it uses.

Energy

seun267 — Thu, 29 Jan 2009 13:40:58 +0000

1st example: of energy changing forms is potential energy. This is because when the object starts moving it becomes kinetic energy also when it stops it becomes potential energy. Entropy is involved because the potential energy is dropping so it is going from a low entropy to a high entropy.

2nd example: is the hand crank machine. It goes from mechanical energy to electrical energy and back to mechanical again. Entropy is here illustrated because and you spin the crank faster and faster the entropy is moving from a low place to a high place.

3rd example: When solar energy is converted to electrical energy buy the solar panels. The solar energy hits the panels and the amount of solar energy that goes in is converted to electrical energy

On the field trip to the Upper Blackstone Water Pollution Plant I learned a lot of things. The plant is for filtering and cleaning the drinking water that comes to them. It is connected to the Blackstone Watershed because water from the Blackstone and other reservoirs flow into the pollution plant. The EPA is connected to it because sometimes they fund the money for the plant, and other times they tell them what to do. Sometimes the Law tells then that the water they had just cleaned is too polluted for the reservoirs. The plant was activated in 1976 and it is able to take in 56 million gallons of water a day since then. They have completed 80 million improvements in the plant. They have also done a 200 million dollar retrofit in the plant.

Light Energy V.s Heat Energy

seun267 — Fri, 09 Jan 2009 03:56:50 +0000

Light energy is reneable and it comes from the sun. The bad thing about Light evergy is that you will need light o power you machines. When the sun goes down you will not be able to do anything until the day comes. Unless you capture and save that light energy.

Heat energy is when the molecules in an object move rapidly which creates heat. To use heat energy you will need a stove that generates heat which also needs gas. Also heat energy takes up space. The faster the molecules move the more space it takes up

Buffalo Farm

seun267 — Wed, 19 Nov 2008 02:22:09 +0000

On the trip to the buffalo farm was really informatory. I learned a lot of new facts like symbiotic living and mutualism. I also learned a lot about the buffalo farm. I learned that they don’t use fertilizers that they let the buffalo grazing and they don’t feed them growth things that make them grow faster. So their meat is really clean with no harmful material to humans.

Compost Worms

seun267 — Wed, 29 Oct 2008 01:36:37 +0000

The worms help comost the food and the leaves by eating it and turning it into soil this helps us beucase the soild that they make is very fertile and it can be used to grow what we need that is why we have the compost bin out there so the worms can make good use of teh food and make us some good soil.

Worm composting is a method for recycling food waste into a rich, dark, earth-smelling soil conditioner. The great advantage of worm composting is that this can be done indoors and outdoors, thus allowing year round composting
