Slide1Planet EarthPart One : The Measurement of Time
Slide2The planet we live on is called Earth.
Slide3It is one of nine planets in our Solar System.
Slide4Theword Solar means, “of or having to do with the sun.”
Slide5These nineplanets orbit around the sun.
Slide6Each orbit equals one full trip aroundthe sun.
Slide7Notice that the Earth’s orbit aroundthe sun is not a perfect circle.
Slide8Earth’s orbit around the sun is called an “elliptical” orbit because it does form a perfect circle.
Slide9There are two points in Earth’s orbit of thesun that are significant.
Slide10They are the “Perihelion” and the “Aphelion”
Slide11“Perihelion”comes from two words, “ Peri” meaning around and “Helios” meaning sun.
Slide12The “Perihelion” is the point in Earth’s orbit when it comes closest to the sun.
Slide13Aphelion is made up from two words, “Apo” meaning from and “Helios” meaning sun .
Slide14The “Aphelion” is the point in the Earth’s orbit when it is furthest away from the sun.
Slide15When do youthink we experience our summers, when we are at the Perihelion or the Aphelion?
Slide16You’re right! We experience summerwhen the Earth is at aphelion.
Slide17Even though the Earth is at the point farthestfrom the sun our hemisphere is tilted towards the sun and we receive more direct sunlight.
Slide18we experience our winter season when earth is at it’sperihelion because our hemisphere is tilted away from the sun and we receive less direct sunlight.
Slide19We call the time it takes the Earth tocomplete an orbit around the sun a year.
Slide20There aretwelve months in our year.
Slide21Four Seasonsin our year: Summer, Fall, Winter, and Spring.
Slide22There arethree hundred and sixty- five days in our year.
Slide23We have fifty-two weeks in our year52
Slide24Each week has seven days
Slide25Each day has twenty-four hours .
Slide26Each hour has sixty minutes .
Slide27Each minute has sixty seconds .
