How a CCD Works

a cell phone picks up the different in the voice. it reads the changes in the pitch and frequency

Two Sides to Every Story

In my opinion I believe there has to be other life out there. Our universe is so big... we don't know how big it is! With billions of other planets in the universe there has to be another earth like planet circulating another sun in another galaxy.

Black Holes - A Type of Dark Matter

A. accretion disk- spiraling gas and dust that spins around a black hole. Can be heated so intensely that it emits x-rays.event horizon- imaginary sphere around the black hole where all matter is crushed to a single point with infinite density.jets of gas- hot gas and energy released in a beam perpendicular to the accretion disk.

B. Gravity is directly proportional to mass, so with more mass comes more gravity.

C. If we are lucky, we could see the contrast between a black hole and bright object behind it. You could also see the jets of gas shooting out of black holes (Quasars).

D. The radius that needs to be breached in order for an object to become a black hole.

E. The space-time fabric described by einstein suggests an unending pit.

James Webb Telescope

A. Measures wavelenghts from 0.6 to 27 micrometers. It picks up infrared light.

B. Comes out in 2013

C. No light has been collected by this telescope yet

D. A 6.5 meter mirror is used

Escaping the Sun

A. # of layers interactions
5 24
10 157
15 174
20 479
25 947
As the number of layers increased so did the number of interactions

B. # of layers interactions
5 31
10 106
15 233
20 433
25 706
the data is about the same. The data is more accurate because there were more photons and it took the average number of interactions

C. ev nm photons sent photons detected
1.5 828 15 14
1.8 690 15 82.0 621 15 13
2.3 540 15 11
2.5 497 15 11
the wavelength goes down. the number of photons detected also goes down

D. ev nm gas atoms photons sent photons detected
2.2 565 O 15 14
2.2 565 Mg 15 132.2 565 Na 15 9
2.2 565 Ca 15 13
2.2 565 H 15 11
it didn't have much of an effect on the number of photons detected

Worked with Billy and Devon

Lab 4: Measuring the Speed of Light with Chocolate

Distance between hotspots = 12 cm
1/2 wavelength = 12 cm = .12 m
Frequency = 2.5 * 10^9 Hz (1/s)
c = speed of lightx = 1/2 wavelength
f = frequency
Equation -> c (m/s) = 2 * x (m) * f (1/s) -> c = (2) (.12) (2.5 * 10^9)
Experimental c = 6.5 * 10^8 m/s
Actual = 2 * 10^8 m/s

Notes on Stellar Spectra

1. it would most likely be fission

2. closer, so you can tell when there is a change in a position

3. brightness of the star

4. absorption is when something is absorbed and emission is when something is given off

5. magnitude is how bright the star really is and intensity is how bright you see it

What is up with Mercury?

1. rotates 3 times in 2 years of that planet

2. radio waves were sent out and they got bigger and a little part came back but the intensity was smaller

3. shows the planet was rotating

Tunguska -What is it?

I think it was a nuclear explosion because radiation was found in the area. Also there was no crater in the area. Also the trees looked as if a bomb went off.

Electromagnetic Radiation

The technological application I think is very important are X-Rays. I think this because I broke my ankle 2 years ago. Without these I would be walking around with bones in my leg that are not lined up correctly. I also would no be able to compete in sports because my leg would hurt.

Annie Cannon

My biggest dream at this time in my life is play baseball at a D1 college. This is my biggest dream because I am very passionate about baseball and playing the best competition in college has been a dream of mine. I would consider playing baseball at the University of Iowa of the University of Northern Iowa. I also want to be a coach in this sport to help kids that love the game as much as I do succeed.

Scaling the Solar System

I found the hallway to be 150ft long.
Earth is 3' 10'' away
Mercury is 1' 6'' away


If I was 3 years old on Earth I would be 12.5 years old on Mercury.


If I weighed 200 lbs. on Earth I would weigh 75.6 lbs on Mercury.
I would be the heaviest on Jupiter.
I would be the lightest on Pluto.

Constellations

Constellation and # of stars

1. Ursa Major 7 stars
2. Ursa Minor 7 stars
3. Corona 6 stars

Mercury

• Mercury Orbits the sun once every 88 days
• Second smallest planet in the solar system
• Closet planet to the sun
• Temperature ranges from 750* to -300*
• Their is no atmosphere on Mercury
  

about me

My name is Dan Marshall. I am a senior at West Delaware High School. I love long walks on the beach just to look at the stars. I also like to play baseball and football. I hate waking up early. I like to hide in Devon Alber's closet to scare people. I enjoy foot long chicken breast on itailian herbs and cheese, provolone, lettuce tomato, pickles, southwest, and mayo.... thank god for the 5 dollar foot longs!!!
