Lena Kelly's How To Be Green slides

1.

• If we keep exploiting natural resources, we might have to colonize to two different planets within a 50 year time period.
• We can do little things like recycling to get our Earth back where it should be.
• Stubborn people are the reasons our Earth is crumbling down. hahaha :)

2. The 50 year time period theory and that incandescent light bulbs can help our environment.

3. Is that 50 year time period theory true?

Recycle :)

I completed slides 1-4

Worst Weather Events

1. Which weather events kill the most Americans?
Flooding kills the most Americans.

2. Which weather events kill the most people (in the world)?
My guess would be a hurricane.

3. Are your answers to those two questions different? Why or why not?
Yes. Because I think more people would die from hurricanes because there is wind AND water. With floods, it could only be water.

4. Read this article. Do you agree or disagree? Why or why not?
I agree because water is really strong. They can do A LOT of damage and they could kill.

5. For your response to #1, find three weather events. Describe what happened (how severe was the storm, did anyone get hurt or die, how much property damage, include pictures, etc.).

Hurricane Katrina and Hurricane Floyd were all very serve and caused a lot of damage. Katrina left 1,800 dead, Isabel left 50 dead and Floyd left at least 57 dead.

Air Pressure Maps

1. Which area of the country currently has the fastest wind speeds? (city, state) How fast is it?
It is about 29mph around Indianapolis, Indiana.

2. Which area of the state currently has the fastest wind speeds? How fast is it?
It is about 20mph around Charolette, North Carolina.

3. Which area of the country currently has the highest air pressure? (city, state) How high is it?
It is about 1022 around Coos Bay, Oregon.

4. Which area of the state currently has the highest air pressure? How high is it?
There is not no numbers on the map.

5. Why does lower pressure usually bring bad weather?
They usually bring bad weather because it brings low temperture which can cause snow storms.

Air Pressure

1. What is air pressure?
Air pressure is the pressure exerted by the weight of air.

2. Where is the closest high pressure system to Fayetteville? (city, state)
Memphis, Tennesse

3. What is the weather (temperature, precipitation, cloud cover) like there?
The weather is 53F, the precipitation is 10% and the cloud cover is partly cloudy.

4. Where is the closest low pressure system to Fayetteville? (city, state)
Boston, Massachusetts

5. What is the weather (temperature, precipitation, cloud cover) like there?
The weather is 45*F, the precipitation is 60% and the cloud cover is cloudy.

Reduce, Reuse andd Recycle

What, specifically about your topic, are you going to research?
I am researching reducing, reusing, recycling and how and if recycling can help our environment.

What conclusions did you come to? What do you recommend average citizens do to make a difference? Be specific. This is the main part of your assignment.
That we can definitely help our environment and how we can. Average citizens can buy eco-friendly shopping bags, reuse water bottles and recycle their trash.


What would happen if, worst-case scenario, nobody listened to your recommendations?
Our environment could be dangered. Global warming could get worse.

What would happen if, best-case scenario, everybody listened to your recommendations?
We could have a healthier and safer environment. Global could decrease and maybe even end.

Astronomy 2 atricles

1. Which article did you read?

Scientists Pinpoint The Edge of Space.



2. When was it published?

On April 10, 2009



3. What are 3 things you learned?

1. The University of Calgary have created a new instrument that is able to track the transition between the relatively gentle winds of Earth's atmosphere and the more violent flows of charged particles in space. With that data, the University of Calgary scientists confirmed that space begins 118 km above Earth. The Canadian Space Agency invested $422,000 into the development of the Supra-Thermal Ion Imager instrument on JOULE-II.



4. What are 2 things you found interesting?

The Supra-Thermal Ion Imager was carried by the JOULE-II rocket on Jan. 19, 2007 and that the ability to gather data in that area is significant because it's very difficult to make measurements in this region.



5. What is 1 question you still have?

How do people find out how to invent these kinds of things??





1. Which article did you read?

Cool Stars Have Different Mix Of Life-Forming Chemicals



2. When was it published?

April 10, 2009

3 What are three things you learned?

Astronomers used Spitzer to look for hydrogen cyanide, in the planet-forming material swirling around different types of stars.

The researchers detected hydrogen cyanide molecules in disks circling yellow stars like our sun.

Hydrogen cyanide is a component of adenine.

4. What are 2 things you found interesting?

Young stars are born inside cocoons of dust and gas, which eventually flatten to disks.

Prebiotic molecules, such as adenine, are thought to have rained down to our young planet.

5. What is 1 question you still have?
How did they find the cocoons of dust and gas??

FIVE astronomy topicsssssss. :D

Black Holes

A black hole is a super dense object that has an intense gravitational pull. There are two parts to a black hole, a singularity and a event horizon. Imagine a star which is much more massive than our sun, which is large enough to cause a black hole to form. What keeps this star from collapsing onto itself and becoming a black hole? The answer is that there is an intense pressure caused by nuclear reactions within the sun. When the fuel that feeds the nuclear reactions gets used up the massive star cannot support itself anymore. It then collapses to form a black hole.

Dark Matter

Dark matter is simply a name which astronomers give to any stuff in the universe which we can detect gravitationally but not actually see. In other words, the material is not emitting light of any wavelength which we can detect, but we can measure its gravitational effect on other objects in the universe. The first evidence of dark matter was found in clusters of galaxies back in the 1930's. Astronomer Fritz Zwicky discovered that the mass of luminous material in a cluster of galaxies was much less than the total mass of the cluster implied by the velocities of the galaxies.

Dark Energy

Dark energy entered the astronomical scene in 1998, after two groups of astronomers made a survey of exploding stars, or supernovas, in a number of distant galaxies. These researchers found that the supernovas were dimmer than they should have been, and that meant they were farther away than they should have been. The only way for that to happen, the astronomers realized, was if the expansion of the universe had sped up at some time in the past. No one really knows if it's anything or not. No can really explain it either.

Big Bang Theory

The Big Bang theory is an effort to explain what happened at the very beginning of our universe.

Pluto

In Roman mythology, Pluto (Greek: Hades) is the god of the underworld. The planet received this name perhaps because it's so far from the Sun that it is in perpetual darkness. After the discovery of Pluto, it was quickly determined that Pluto was too small to account for the discrepancies in the orbits of the other planets. Now, it is known as a dwarf planet.
