  2. INVESTIGATION ONE

  3. The EARTH • As the Earth moves in two different ways in space • Rotates or spins counter clockwise on its Axis, imaginary line that runs in a straight line from South Pole towards the North Pole on a 23.5° angle • It takes the Earth about 24 hours to complete one rotation= 1 Day • Revolves or moves around the sun in an elliptical path; this path is known as an orbit. • It takes the Earth about 365 days to complete one revolution= 1 year

  4. Daylight and the seasons Day and Night Seasons • During the Earth’s Rotation around the Sun the surface of the Earth that is facing the Sun has Day time • While the other surface, facing away from the sun has Night time • The earth is divided into 2 hemispheres • Northern Hemisphere (above the equator) • Southern Hemisphere (below the equator) • When the Northern Hemisphere is experiencing Winter the Southern Hemisphere has Summer. • Similar with Spring and Fall

  6. Investigation Two

  7. The Moon • The Earth has one object in a constant orbit around it- the Moon • The Moon revolves around the Earth, held in place by the Earth’s field of gravity

  8. The Moon • As the Moon revolves around the Earth, it revolves around the Sun with the Earth • Resulting in viewing different portions of the moon that are illuminated by the light of the Sun • Visible portions of the Moon are called the Phases of the Moon

  9. Movement in our Solar System • It takes the Earth 24 hours or one day to complete 1 rotation around the Sun • Seven days for the Moon to complete ¼ revolution around the Earth • About 28 days to complete a full rotation around the Earth

  10. Movement in our Solar System • The Sun is the center of the Solar System • The Earthrevolves around the Sun while rotating on its axis • While the Earth revolves and rotates, the Moon revolves around the Earth

  11. Phases of the Moon • New Moon- no moon can be seen • First Quarter- half portion of the moon can be seen • Full Moon- full circle of the moon can be seen • Last Quarter- half portion of the moon can be seen

  12. Phases of the Moon • Crescent is when only a sliver of the moon can be seen • Waxing- moon looks like it is growing • Waning- moon looks like it is shrinking

  14. Observing Different phase of the Moon: New Moon • Position of the Sun, Earth, and the Moon cause the phases of the Moon. • When the Moon is between the Earth and the Sun, the Sun shines on the side of the moon that is not facing the Earth- on Earth we cannot see the moon because the side near us is not illuminated

  15. Observing Different phase of the Moon: Full Moon • When the Moon is opposite the Earth from the Sun, the Sun shines directly on the Moon, allowing us to see the entire surface of the moon, which is facing the earth. • The Moon looks like a full circle

  16. Observing Different phase of the Moon: Quarters, Gibbous, and Crescent • The Sun shines on some portion of the surface of the Moon which faces the Earth • In these positions the Moon does not appear to be a full circle but as a part of a circle • Different patterns of a circle appear to be illuminated at different times because of the revolution of the Moon around the Earth

  17. Observing Different phase of the Moon First Quarter Last Quarter

  18. Investigation Three

  19. First Law of Motion • An Object in Motion Stays in Motion unless acted on by an outside force • First Law of Motion applies to the Sun, Earth, Moon, and all other planets • Unless a planet is acted on by a force, its motion in Space will not be altered.

  20. Investigation Four

  21. Gravity • Gravitational Force- the force that exists between all objects because of their mass. The force of gravity acts to pull objects together

  22. Forward motion and Gravity • The combination of forward motion and gravity are important cause the planets to orbit the Sun and Moon to orbit the Earth. • Without this precise amount of gravity, planets would either fly out of orbit in a straight line or be pulled towards the Sun.

  23. People to know

  24. Nicolaus Copernicus • Formulated a model of the universe which placed the Sun, rather than the Earth, at the center.

  25. Galilei Galileo • His contributions to observational astronomy include the telescopic confirmation of the phases of Venus, the discovery of the four largest satellites of Jupiter, and the observation and analysis of sunspots. • Defended the idea that the Earth revolves around the Sun during the Roman Inquisition

  26. Johannes Kepler • Laws of Planetary Motion • Incorporated religious arguments and reasoning into his work

  27. Williamina Fleming • Helped develop a common designation system for stars and catalogued thousands of stars and other astronomical phenomena. • Contributed to the cataloguing of stars that would be published as the Henry Draper Catalogue. • Published a list of 222 variable stars she had discovered.

  28. Neil Armstrong • Americanastronaut and the first person to walk on the Moon. • "That's one small step for a man, one giant leap for mankind"
