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.
