Pennsylvanian Period

Summary

            The name of my period is Pennsylvanian Period. This period went from 286 to 325 million years ago. In that time the first reptiles appeared and may ferns. Life in the Pennsylvanian Period. The age of amphibians appeared, many insects are evolved. In that time some reptile appeared plant are verg huge like 45m tall.

Reflection

1. What did you enjoy most about this project?
     The thing that I most enjoy about this project is everything about this project, because I enjoy to like to find information and create a video.

2. What was most challenging about this project? Why?
   The most challenging about this project is to find information, because I don't know the information from internet is correct or not.

3. What you change about this project and why?
    The thing that I want to change about this project is to easy to get the information and understand it, because the information from internet is correct or not correct.

4. What are 3 thing that you learned from this project?
   -How to create a video
   -I learn the time of the Pennsylvanian Period (386 to 325 mya)
   -In Pennsylvanian Period have many insect are evolved 

Star

1. What is a star?
A star is a big gas ball. They have different colors, size, temperature and luminosity. The star made of gas and dust.

2. Types of Stars.
The four main types of stars- Whiter dwarf, Main Sequence, Giant, Super Giant. The characteristics of stars is  ages, size, temperature, luminosity, color and spectral class.
Ages- Young Stars, Middle Age Stars, Old Stars
Size- Small Stars, Medium Stars, Large Stars
Temperature- Hot Stars(30000°-10000°), Medium Stars(10000°-4000°), Cold Stars(4000°-2000°)
Luminosity- Bright Stars(100000-100), Medium Stars(100-0.1), Dim Stars(0.1-0.0001)
Color- Blue, Blue- White, White, White- Yellow, Yellow, Orange, Red
Spectral class- O B A F G K M

3. H-R Diagram
H-R Diagram is a graphical tool that astronomers use to classify stars according to their temperature, luminosity, color, spectral types and evolutionary stage.

4. Nuclear Fusion
Nuclear Fusion is two Hydrogen gas molecules into a Helium molecule inside the stars. The nuclear fusion is create the star energy. H+H=He

5.The Life Cycle of a star
First, all the star is born are Stellar Nebula. The stellar nebula is a cloud giant star. There have 3 different types star. Is the Sun-Like Star,Huge Star, Giant Star.
Sun-like star is born with Stellar Nebula, then become Red Giant, Planetary Nebula, White Dwarf, and last is Black Dwarf.
Huge Star is born with Stellar Nebula, then become Red Supergiant, Supernova， and last is Neutron Star.
Giant Star is with Stellar Nebula too, then become Red Supergiant, Supernova，and last become a Black Hole

Interesting Facts:

1.    Sister planet with the earth, many thing are almost like the earth.

2.    No moon

Hurricane Irene Project

Critical Thinking

Hurricane

1. What effect does water temperature have to the creation a hurricane?

The effect that water temperature have to the creation a hurricane is the hurricane will the water become warm. 

2.Why would there be more damage to an area during high tide?

There be more damage to an area during high tide, because the water will get in to the ground.

3. If an area is fully saturated, how will this be more dangerous for an area?

Tide

If an area is fully saturated the hurricanes will make the water became the flooding.

4. Why would there be more flooding if the ground was fully saturated?
There be more flooding if the ground was fully saturated the water won't have place to go then became the flooding.

Reflection

1. What is something that you liked about this Mini-Project?
About this Mini-Project I liked to learn many thing about the earth and we use computer many time.


2.What was difficult for you on this project?
The difficult thing for this project is learn thing and get more information from other group.


3. What would you change about your work on this project?
I would't change anything, because I very like this project.


4. How did this project help you learn about Hurricane Irene?
This project help me learn the hurricane is very damage, what happen during hurricane, what effect is happen, like the water cycle, flooding.
