Geologic Time-Devonian Time

Devonian Period
Devonian Period existed 408-360 million years ago and it was a period where a lot of fishes, land plants and lot of other organisms appeared and became diversed. 
For example: first tetrapods, first amphibians, first sharks, coral reefs, new insects and much more.
During this period, two supercontinents were formed "Gondwana and Euramerica."








1. What did you enjoy most about this project?
From this project, I enjoyed that we had to find informations about our period and learn more about what happened during that time.


2.What was the most challenging about this project? Why?
Doing the reference paper was the most challenging part of this project because finding pictures and doing the reference paper was really confusing.


3.What you change about this project and why?
I would not change anything about this project because even though it was a hard, it was really fun.


4. What are 3 things that you learned from this project?
I learned about when did this period started, how was life on earth during this time period and what organism lived, and about the geologic events.

The Stars-Blog Entry




1.What is a star?

Stars are huge balls with gas and dust. Stars are made of a huge cloud called Stellar Nebula. This huge cloud starts getting smaller because of the gravity and while it gets smaller, it gets hotter too and nuclear reaction stars in the middle. After all this, a star is born. If we look up in the sky, they look really small, but in fact, they are much bigger, hotter and brighterStars have different names, color, size, type, temperature, magnitude(luminosity) and spectral class. Stars can be blue, yellow, orange, red and white. Blue stars are consider as hot stars and red stars are consider as cold stars.



2. Types of Stars
Stars have different types and those types are: super giant, giant, main sequence and white dwarfs.
Super giant stars which are one type of stars, are known as the largest stars and some of them are bigger than our solar system. When these type of stars die, they turn into supernovas and become Black Holes. Some of these stars are: Betelgeuse, Rigel and Deneb.
Giant stars are one other type of stars. They are huge stars and they have different color, size temperature and magnitude. They have spectral class too which represents the temperature of the star and the letter changes according to the star temperature. Some of these stars are: Polaris(North Star) and Aldebaran. 
Main sequence stars are type of young stars with different color, size, temperature and magnitude. These stars lay on a diagonal from hot and bright stars to cold and dim stars. One important star that is included in this type of stars is Sun.White dwarf are type of stars in which the stars of this type are consider as small, hot stars. The stars of these type, as all the other stars have different color, size, temperature and magnitude. They have almost the same size as Earth but they are heavier. When these stars lose their heat and become cold, they will become Black Dwarfs and some of these stars are: Sirius, 40 Eridani B and Procyon B.


3. H-R Diagram
H-R Diagram is also known as "The Hertzsprung- Russell Diagram"and is a diagram used by astronomers to classify stars according to their luminosity, spectral class, color, temperature and evolutionary stage. This diagram shows types of stars which are: super giant, giant, main sequence and white dwarfs.



4. Nuclear Fusion
Nuclear Fusion is a reaction inside the star that changes two Hydrogen (H) gas molecule into Helium (He) molecule. Nuclear Reaction helps a star to born because the huge cloud or Stellar Nebula gets smaller and while it gets smaller, it gets hotter too and inside of it Nuclear Reaction happens. Nuclear Reaction is a Reaction that creates the main source which is Energy.





5.The Life Cycle of a Star
Sun-like stars, huge stars and giant stars are three different groups of stars that have different life cycle but all of them are created from a huge cloud with gas and dust called Stellar Nebula.
Sun-like stars first starts with Stellar Nebula and then it becomes Red Giant. After it become red giant, become a cloud with gas and dust called Planetary Nebula. After this, it becomes White Dwarf and than turns into a cold, dark object called Black Dwarf.
Huge Stars starts with Stellar Nebula too and it becomes bigger to a Red Super Giant, but than it explodes to a Supernova and starts to collapse into a Neutron Star.
Giant Stars starts from Stellar Nebula, it gets bigger into a Red Super Giant, explodes into a Supernova but at the end, become an invisible object called Black Hole.

Planet Saturn

Saturn




Planet Order: 6th from the Sun (1-8 away from the Sun)
Distance From The Sun (km): 1.4 million km.
Mass: 5.69x10^26 kg.
Diameter: 120.536 km.
Rotation: 10 hours and 14 minutes.
Revolution: 34.821 km per hour.
Number of Moons: 60.
Jovian.


Planet Description (What is it like on this planet?):
Saturn is a planet that is similar to Jupiter but is a little bit smaller, but is the second largest planet in our Solar System after Jupiter. It is a gas giant planet. Saturn is the least dense planet in our Solar System and is made up of mostly hydrogen and helium.

2 Interesting Facts:
1.Saturn has seven rings orbiting around it and three main rings are called the A,B,C rings named by the astronomers who discovered them.
2.Sometime is easy to see the rings of Saturn if we use telescope, but sometimes they disappeared and this happened in 2008-2009 and it will happen again in 2024-2025.

Hurricane Irene Project




Critical Thinking

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

Hurricane is a topical cyclone that happens in the summer when the water is warm. So in summer, there are higher chances of a hurricane to happen than in winter.
2.Why would there be more damage to an area during high tide?
Because when there is a high tide, means that the water level is high and that can cause flooding, saturation and damages.
3.If an area is fully saturated, how will this be more dangerous for an area?
In these saturated areas, the ground is too wet, and when the ground is too wet it can not handle it and that can cause damages.
4.Why would there be more flooding if the ground was fully saturated?
Because flooding is when water accumulate and covers every space, so if the ground would be saturated or too wet, it would cover every space and cause flooding.

Reflection



1.What is something that you liked about this project?
I liked making my own blog.
2.What was difficult for you on this project?
Answering some questions was a little difficult.
3.What would you change about your work on this project?
I would collect more information to be more specific on my answers.
4.How did this project help you learn bout Hurricane Irene?
I didn't know a lot about Hurricanes until we started this project. This project helped me to understand more about this topic and learn more about it's causes and effects.
