Geologic Time Scale

Description 
The Paleogene Period was During 65 to 25 years ago. The temperature was usually low. The lands that connected were Antartica and Australia, North America and Europe, Europe and asia. It is the time when the first mammals appeared.




1.What did you enjoy most about this project?
The thing I enjoyed most about the project was making the video and choosing the songs for it.


2. What was most challenging about this project?
The  most challenging part of this project was to find reference for eveything you use such as pictures and information.
3. What would you change about this project and why?
I would change the amount of tine we had to work on it because it wasn't enough for me and I couldn't get it done on time.

4. What are 3 things that you learned from this project?
The that things I learned about this project are don't waste time playing around get as much things done as you can. I learned about the ice age and I also learned about the first mammals appeared during the Paleogene Period.

the stars

what is a star
A star is a giant ball of gas and dust with very hot temperature. Star are sometimes very big even bigger than the sun. howvever they look very small to us on earth and are only visible at night time. It is hot because in the center it has nuclear fusion. they can be different colors and sizes.




Types of stars

There are four types of stars. First there are the supergiants these stars have the highest luminosity and different degree of temperature. Secondly there are the white dwarfs these stars are white and have the lowest luminosity and high temperature. Thirdly there are the giants but there are different kinds: there are the redgiants, the bluegiants and the yellowgiants. These stars have highest luminosity and low temperature. Lastly there are the main sequence stars these stars have different luminosity temperature and sizes.


H-R Diagram
The H-R Diagram is like a graph where we sort the stars base on their luminosity, temperature, type, color, spectral class, size and name. It gives all the necessary information about stars.















Nuclear fusion
A star is a giant ball of hot gas. In the extremely hot center there’s nuclear reaction, it turns two hydrogen gas into helium molecule this process is called nuclear fusion it creates energy.






The life cycle of a stars
First of all the star assembled inside of the stellar nebula then it becomes a sun-like-star then it grows into red giant after it explode into a planetary nebula then the pieces pack up together to become a white dwarf and get smaller into a black dwarf.
It is created inside of the stellar nebula, it become a huge Star then it gets bigger into red super giant then it immensely explode into supernova after it gets small into a neutron star.

Planet Description 
Uranus has a very thick cloud cover and the atmosphere is made up of hydrogen, helium, methane and ammonia and it has 11 rings.

Interesting Facts  
Uranus is the fourth massive planet. It was named after a greek Deity of the heavens, the earliest supreme god. It is the third largest. It is the coldest planetary atmosphere in the solar system and it is the only planet which rotates on its side.

Critical Thinking

1. What effect does water temperature have on the creation of hurricane?
When the ocean water gets too warm it creates the tropical cyclone which is a strong wind that forms the  hurricane.

2. Why would there be more damage to an area during high tide?
There would be more damage to an area during high tide because during high tide the water level increase, which means there would be strong waves and the water would come onshore and cause flood.

3. If an area is fully saturated, how will this be more dangerous for an area?
This will be more dangerous for an area because the water does not go into the ground, it stays on the ground if the water level increase it can cause flood in the area and the trees in the area will fall down.

Reflection

What is something the you liked about this mini-project?
The thing I liked is that we learned what causes hurricane and I also learn that the same water goes around and comes around from the water cycle part.





What was difficult for you on this project?
The thing that was difficult about this was to write a paragraph for each topic: hurricane, groundwater, tide, flood simply from the presentation and notes we gat from the students and to include vocabulary word in it too. 

What would you change about your work on this project?
The thing I would change is that I would underline the vocabulary words which I forgot to do so that I wouldn‘t lose point. 

How this this project help you learn about Hurricane Irene?
This project helped me learn that hurricane happen when the ocean water is too warm, that hurricane causes flood and that the strong wind breaks the trees.
