Summary: Permian Period longing from 280 to 248 millions years. It is Known as "The Age Of Amphibians". During that time there were many reptiles, invertebrates and marine animals. They dominated the most. Permian Period ended causing earth's mass biggest extinction. Scientists all have aspects on how this happened. One of the major one is because a change occured during permian period and those organisms weren't able to adapt to their new evironment.
Reflection
1. What did you enjoy most about this project?
I enjoyed researching for information about my topic because I've learned interesting fact about it. I also enjoyed looking at pictures of animals from other period because there were all fabulous to me.
2. What was most challenging about this project? Why?
I would probably say the most challenging about it was findind picture of organisms from the oldest period. Since it's really old , I think they didn't give enough picture. It took more than two days to find an accurate picture of organisms from permian period. I had to look carefully because some of organisms given were from jurassic period.
3. What would you change about this project and why?
I didn't like the idea of having to write references for every website used because it's very complicated. It took most of my time and it was rare to find all information in one specific website. I had to use many different websites in order to find more picture and information.
4. What are the three things that you learned from this project?
The main thing I learned was geologic events of earth's history. For example I learned that Devonian period was known as "The Age of fish" because there were many different fish and there were most abundant. I learned that many extinctions occured and also organisms evolved from those organism that have gotten extinct. I also learned that mountains and volcanoes began to form at certain period.

the stars

| Stars!!;) |
What is a star?
Stars are large balls of hot glowing gas, and they have various different sizes and colors. Stars can be orange, blue, red ,yellow and white. Some stars are bigger than the sun, which is also a star. Even though they look really small up in the sky, they are apparently really big. Stars are either bright or dim and they also either cold or hot.

Type of stars
They are four different types of stars:
They are four different types of stars:
1)Super Giants are middle ages, medium, large, orange, cold and bright stars. Super Giants' spectral class stars from A to M.
2)Giants are middle ages , small, medium, red, cold, bright and dim stars. Giants' spectral class starts from G to M.
3)Main Sequence are middle, medium, white, yellow, orange, hot, cold stars. Main sequence’s spectral class starts from O to M.
4)White Dwarfs
are old, hot, medium, blue and white stars. their spectral class stars from B to F.

Map Astronomers used to classify stars by their luminosity, name, size temperature , color, type and spectral class. It helps them distinguish stars in different categories.

Nuclear fusion
when a star change hydrogen gas molecule into helium molecule and creates energy. Stars make their energy from nuclear fusion.

Life cycle of a star
first they were Stella Nebula, a big giant cloud of dust and gas. Gravity shrinks the clouds. it creates sun like stars, huge star and giant stars.from sun like stars , they became red giant, then planetary nebula( a cloud of gas and dust), later white Dwarf, it gets smaller and smaller and turn into black dwarf(a cold, dark object)
From Giant stars, it became red super giants, then supernova and finally black hole( when star collapse after an explosion)
from huge stars, it became red giants, then supernova( a giant explosion caused when stars burst) and last Neuron star( a small, dense object that spins very fast)

| Mars |
Rotation: 1.026 days
# Of Moons: 2
Terrestrial Or Jovian: Terrestrial
Diameter : 227.9 million kilometer
Diameter : 227.9 million kilometer
Planet Description:
Mars is the fourth planet, it is somehow compare to earth. It has four seasons just like earth. However because of Martian year is about twice as long as earth's. It also has polar ice caps
Interesting Facts
Mars is called Red planet. Mars might have thick atmosphere, blue skies and abundant liquid water on it's surface. It is possible there's biotic factor ( living things) in Mars.

Critical Thinking
 |
| Hurricane |
Hurricane occurs in summer time. During that time the ocean is extremely warm. Tropical cyclone often happen in the warmest part of the ocean. Tropical Cyclone is a strong wind that creates hurricane.
How can the timing of the tides (high or low) effect the devastation of hurricane?
Tides are the daily rise and fall of the ocean. If an hurricane happens while the tides' level is high, it will cause flooding. Which means a high amount of water will get out of the ocean and will stay immobile at one place.
If an area is fully saturated, will a hurricane have more or less impact on an area?
Eventually, if an area is fully saturated, hurricane will have more impact on this area. The main reason is because the water couldn't infiltrate deep into the ground, it was already wet. From the additional rain of the hurricane, there will be ground water and that certainly will result to a flood.
How does groundwater saturation affect rivers and streams?
Ground water saturation causes the rivers and streams' water level to increase. It also causes rivers to overflow.
Reflection
What is something that you liked about this Mini-project?
I liked the fact that we got to study about natural disaster and especially hurricane. Last time when hurricane Irene happened, I was wondering how did it happen. Now I know the answer.
What was difficult for you on this project?
The most difficult thing for me was finding the right answer to certain questions.
What would you change about your work on this project?
I think it could have been better if each group presented their topic to the whole class. I would have had more time to ask questions.
How did this project help you learn about Hurricane Irene?
During this project I learned about the causes and effects of hurricane. There was a student who had studied all matters about hurricane with his/her group. He/she gave a short presentation about it. I also had a mini lesson about hurricane. It was taught by my teacher. I had to read a short paragraph about hurricane and answer some questions about it. All this contributed and helped me have a better understanding about hurricane Irene.
