  1. CRCT Question Ptolemy believed the __________ was the center of the universe. Sun Earth Moon Jupiter

  2. The Name Game

  3. Gravity

  4. Nicholas Copernicus http://www.lucidcafe.com/library/96feb/copernicus.html

  5. Geocentric

  6. Ptolemy A.D.140 http://web.hao.ucar.edu/public/education/sp/images/ptolemy.html Reasoned that the Earth was the center of the universe.

  7. JOHANNES KEPLER 1571 TO 1630 NASA

  8. Inertia

  9. Galileo Galilei 1564 - 1642 http://www.pbs.org/wgbh/nova/galileo/images/scie_galileo2.jpg

  10. And then came - Sir Isaac Newton

  11. Quiz • Make sure your name is on it • Put in SCIENCE bin when finished 

  12. Gravity Tricks

  13. The Impossible Leap: While standing up, bend over and hold your toes with your hands, keeping your knees slightly bent. Try to jump forward in this position without removing your hands from your toes while you are jumping. Can you do it? Bet you can't!

  14. The Science: In this position, you can jump backwards from one end of the room to the other, but you won't be able to jump forward even a single leap! When we jump, we first shift our center of gravity in the direction we want to jump, and then we move our support base in the same direction to regain our balance. When you are holding onto your toes, jumping backwards is not a problem because you can use your heels. But to jump forward, you would have to use your toes... and your fingers are in the way

  15. Super Glue Chair • Sit in a straight-back armless chair, keeping your back against the back of the chair and your feet flat on the floor. • Fold your arms across your chest. • Keeping your feet flat and your back straight, try to stand up. • Are you glued to your chair?

  16. The Science: In this sitting position, the center of gravity is at the base of your spine. By trying to stand up with your back straight, you prevent the center of gravity from moving to a position above your feet, which would be necessary to stand up. Therefore, you remain glued to your chair

  17. Nebular Theory How the Solar System formed!!

  18. Our Solar System It was formed 4.6 billion years ago.

  19. A star that explodes is said to have gone SUPERNOVA. It produces a lot of ejected matter.

  20. A nebula is the cloud of gas and dust that remains after a supernova event.

  21. Horsehead Nebula in the Constellation Orion NASA

  22. Planetary Nebula NASA

  23. Formation of the Solar System

  24. Shock waves from space started gravitational forces to spin and collapse the material found in the nebula.Most of the material fell to the center forming the sun (99% of the System’s mass).

  25. Planets closest to the sun lost their low mass gases ( H and He) due to the heat from the sun. These are the inner or terrestrial planets. NASA

  26. Planets further from the sun kept their light gases and formed the gas giants with small rocky cores. NASA

  27. Look at Pluto’s orbit. This is one reason it is not considered a planet.

  28. Check out Pluto’s orbit!!!

  36. photosphere Granules: convection from inside the sun causes the photosphere to be subdivided into 1000-2000km cells that look like rice grains or kernels of corn. NASA
