Vocabulary:



Word
Native language
(Russian)
Definition
Axis
Oсь
The imaginary line through the Earth.

Tilt
Hаклон
The angle from right position to side by 23.5°.

Equator
 Экватор
The line divides earth into two hemispheres.

Revolution
Оборот /  Вращение
When object goes around another object.

Orbit
Oрбита
The way planet goes around. Earth orbit is called Ellipse.

Equinox
Pавноденствие
The equal day and night by 12 hours each. There is two equinoxes: Vernal and Autumnal.

Solstice
Cолнцестояние
Position of the sun depending on the seasons. There is two solstices: Summer and Winter.

Summer
Solstice
Летнее
Cолнцестояние
The longest day of the year. It happens on June 20/21.

Autumnal
Equinox

Oсенний
Pавноденствие

It happens on September 21/22 and 1st day of the fall.

Winter
Solstices

Зимнee

The shortest day of the year. It happens on December 21/22.

Vernal
Equinox

Bесенний
Pавноденствие
It happens on March 21/22 and 1st day of the spring.

Direct
Sunlight

Прямый
 Cолнечный Луч
When sunlight is straight comes to Earth.

Indirect
Sunlight

Kосвенный
Cолнечный Луч
When sunlight is not straight but in little angle comes to Earth.



Summary: 



Solstices and equinoxes happen because of revolution. Earth spins on it axis as known rotation. Earth tilted to side for 23.5°. An equator divides Earth into two hemispheres: Northern and Southern. There is two solstices: Summer and Winter. Summer solstice happen when earth axis point toward to sun. Direct sunlight comes to northern hemisphere and on the Earth in North Pole are summer season on June 20/21. Same time in southern hemisphere weather is winter season. Winter Solstice happen when sunlight comes in little angle, specific they are not straight which called indirect sunlight. Equinoxes are when equal day and night. There is two equinoxes: Autumnal and Vernal. Autumnal equinox is fall season which starts on September 21/22. Vernal equinox is spring season that starts on March 21/22. The shape of Earth orbit is Ellipse. All these changes happen through movement around the Sun.






Critical Thinking Question: 
How is earth affected by movement (revolution)? 


The Earth is affected by movement. This statement proven by revolution. Revolution happens when the Earth goes around the Sun. The way earth goes around the Sun is called orbit. Climate and time change by this movement as known Solstices and Equinoxes. Solstices is when longest or shortest day of the year.  Equinoxes is when equal day and night. Summer solstices happen under direct sunlight when is longest day of a year on June 20/21. Winter solstices happen under indirect sunlight when is shortest day of year on December 21/22. Autumnal (fall) or Vernal (spring) equinoxes happen when earth gets equally sun rays in both hemispheres. All these events cause by earth movement. 


Reflection: 
  • What did you enjoy most about this project and why?
    My most enjoyed part of this project is making video. In addition I was movie editor that help me gain knowledge about imovie. Because we cooperated together and tried to make good and well enough. I enjoyed of doing my work at this project. I hope, I did well.
  • What was most challenging for you during this project and why?
    Throughout this project I didn't have challenges. Because members of group exactly knew what to do and helped me to make necessary things. Also teacher gave me all required paper and guide that helped me to figure out quickly. Collaboration and communication skills were helpful to finish on time. 
  • What new skills did you learn from doing this project?
    I learnt how to work with imovie software and edit movie that has been done by group. The program worked well, editing process was easy but not enough skills, didn't give me chance to make unique well. By learning how to work with this program, I made some changes and some classmates already gave me feedback. Next time I will use learnt skills to make more interesting. 
  • Is there anything that you could have done to improve any of your work?
    Yes, there is something that I could have done to improve my video. I looked through my classmates works and I realize about I need to add some thing to make unique. For example add some captions and song during video. Another parts of our group work has been done perfectly. I wouldn't change anything else except this small detail.

The Geologic Time Scale

The Neogene Period

Fossil of Fish




Summary of Neogene Period: The Neogene period was the age of mammals. It is in tertiary period of Cenozoic era.This period is consisted of 2 Epoch: Pliocene (5-1.8 mya);
Miocene (24-5 mya). Miocene is about mammals, bears, horses, monkeys and birds.

The Paleogene Period-extra credit

Anadara Vanderhoofi






Summary of Paleogene period: Paleogene was period of made up life in the Earth.  The Paleogene consist of 3 epochs: Oligocene, Eocene and Paleocene.  New living thing appeared on this period such as first large mammals, deer, pigs, cats, rhinos, tapirs and new form of whales.

Reflection


What did you enjoy most about this project?
I enjoyed the most about this project when I was working with partner and the events that happened in the past were interesting. My partner promotes me to finish it on time. Also the project has different things like video by Animoto and glog by Glogster. We able to divide the work and did it in collaboration.


What was most challenging about this project? Why?
Most challenging about this project was in the periods and references. Because the periods are related to each other and ages of those periods are old. It was complex to find right information.  In addition I never did bibliography before. The web site that I took information and put link and typed the name was extra work and I got confused.

What you change about this project and why?
I would like to leave as I have now and don’t change anything about this project. Because before do this project I discussed with partner the ideas we have. Furthermore my partner was creative that she helped me to figure out the glog by giving new look. I think we did awesome also we are done with extra work.

What are 3 things that you learned from this project?
Something that I learnt from this project is the history of planet Earth. From this history I learnt about Neogene and Paleocene periods. The Neogene was the age of mammals, the Paleogene was the period of made up life in the Earth. In the Paleogene period the continents began to forming and new animals appeared on the Earth. In the Neogene period cause of hot climate that made dry forests and deserts in Australia continent. This project is helpful to understand better about Geologic Time Scale.
