  The big question addressed in lab, and a description of what you did. We presented our presentations today, here are some notes from each presentation  origin of the universe  big bang theory'  the universe is exapnding and has no center  stars formed 200 million years after    Life cycle of Stars  stars are not the same size, giant, dwarf, super giant stars are constantly moving  stars are all diferent colors ( misconceptions is stars are only yellow) 7 stages  giant-gas clod protostar  T-tauri phase  main phase  red giant - temp cools down  elemental fusion  supernova/white dwarf  Origin of the Earth  evidence that earth was formed before the Big Bang  formed slowly through many collisons  earths surface has changed over time  Black Holes  light was dedected in black holes vary in sizes depedning on mass  radiation escapes black holes  so dense gravity lays below  ...

  The big question addressed in lab, and a description of what you did. In lab, we created our model of the sun, 4 inner planets, and our moon, that is according to scale. When creating our model, we had to take distance, size, and shape, into consideration.  We scaled our solar system using millimeters. We found it hard to make the planets by size because they were so tiny, some being half of a mm. We tried our best to make them to scale.  A description of what you learned in Thursday's lecture. Preconceptions (standard misconceptions on your topic) What is the current science understanding? Other:  What was the historical version Cool facts Women, Iowan’s, other relevant connections? Etc…. THREE multiple choice test questions, as a team, bold the answer you feel is most correct.  My daughter had a band concert last night, after the concert we walked home. We were walking to the East and they could see the moon was behind the clouds. They asked me what phase th...

What are your best understandings about....     How the phases of the moon occur?  Depending on the earths rotation and how much of the sun is covering it. I think of it as a shadow.     What causes the seasons?  Northern and Sountern hemisphere, which side is closer to the sun, as the earth rotates      What causes a lunar  eclipse?  When the sun and moon  align.  The big question addressed in lab, and a description of what you did. Seasons depend on the tilt of the earth. If northern hempishere is tillted towards sun, that means it is summer. If it is tilted away, it would be winter. The earth's orbit is almost exaclty a perfect circle.  Sun, moon, earth - new moon :  solar ecplise- perfect position aligned  sun, earth, moon- full moon : lunar ecplise- perfeectly alligned  the moon has its own movement on its own access therefore sometimes it is aligned with the sun and moon (eclipse) and other t...
