The Triassic Time Period                                                                              

The Triassic period start at 248 to 206 million year ago. Triassic time period also a huge landmass. Like africa and the south america come together and form pangea. Bunker is a rodck layers find in germany. In the Middle of the Triassic time period Laurasiz and gondwana were the only two contiemenet. Some Events That happen in my time period were extintion of spicies, Volcanic Eruption . the only spicies that were alive are Eazstrodon, Theriodontio and pterrosaurs. They were also plant in my time period are Glossoptnis and cycads.

 

Reflection  

1.  What did you enjoy most about this project?
     This project was great as miss Kara give us chance to work independently and give us enough time to finish it with Extra Credit and I also enjoy making blog and researching the picture of the organism livings during Triassic period. It was incredible to think about those ancient organism which were once alive in this world.
2.  What was most challenging about this project? Why?
     The most challenging part of this project was that we had to make Reference and it was hard to write information about every single web were we find our Data of the project. And I also feel little hard about finding information since there was different information on different websites. So it was hard to decide about which one to choose. because we always try to gave specific information and we have no idea about which information could be correct about our period but by Ms. Kara's help I got perfect information.
3.  What would you change about this project and Why?
     Some thing I would like to change about this project is to let every body choose which period they want to (Interesting period for them) work on and I would gave more time to work on this project that the students can learn more about their period (about this project).
4.  What are 3 things that you learned from this project?
    I learn lot of things about Earth history especially about earliest life on Earth.

• How mountains formed.
•  How animals moved from water to land.
• Which generation exist during what time and which species and genera was died during that period.
• When was dinosaurs existed. 
• We determine lot of vocabulary and most interesting facts about earth history.

The stars - Blog entry

1. What is a star ?
A star contains huge balls of hot gas. The star looks small from faraway because they distance from us, but a lot of the stars are very huge and brighter than the sun. Nuclear fusions create heat in the center of the star. Many star have different size and colors also temperature.

 2. Type of Stars

Stars are order 4 different types. They are Super Giant, Giant, Main Sequence and White Dwarf. They are also order in other 6 different way categories, ages, size, temperature, luminosity, color and spectral class.
White dwarf stars are white old stars and very small, temperature is in between 4,000 to 7,000, they are dim stars, spectral class of white dwarf can be A, B, F. Main sequence stars are medium stars that can be any colors, temperature and luminosity, they all have different spectral class. Giant stars are large age star, it can be any color, temperature and luminosity, so spectral class can be different too. Super giant stars are super huge middle age stars that can have any color, temperature luminosity and spectral class.

 

3.H-R Diagram

      H-R Diagram which stands for Hertzsprung-Russel Diagram. H-R Diagram is a graphical tool that use to classify stars by their luminosity, spectral type, color, temperature and their stages.  

 
 4.Nuclear Fusion
Nuclear fusion is a nuclear reaction which have to energy source called hydrogen gas molecule. Nuclear reaction inside of a star change two hydrogen gas molecule into helium molecule. When this happen a star makes energy.

5.The life cycle of a Star
  All stars is made of a giant cloud,it has gases and dust. Called Stellar Nebula. It can made the three type of star.
