Remember that some questions need at least two sentences!

1. Number C best describes Earth
2. An object pulls another object toward the center of itself.
3. I think that a tennis ball with a rubber band is most useful for describing gravity
4.  Models are useful because they give a visual description.
5.  The moon is affected by Earth because it is pulled by it's gravitational pull. It doesn't slam into Earth because the moon emits a gravitational pull of it's own .
6. . The plane doesn't fall to the ground because the plane has something called lift. Lift is the push that something uses to push themselves into the air.
7. . No, gravity does not ever stop working, but stuff can cancel out gravity. One way is to have a revolving thing, and it's revolution generates a gravity of it's own and cancels out gravity.
8. . This lesson is a good time to teach about craters because we learn that craters form when something hits it. To hit the earth something has to get pulled by gravity and enter it's atmosphere to hit the earth.

Notes from my research

• The horizon line 
• The shadow of earth on the moon
• Stars
  
• Shadows
  
• Time zones
  
• Standing on a cliff and looking farther
  
• Pictures from space 
• Contrasting and contradiction to other planets
• Gravity beacuse if the earth was flat you would allways be pulled back to the middle

Notes from videos

• ​We knew that earth was round 1000 years ago
• One of the reasons are the moon
• The only posible shape that can cast a rounded shadow is a sphere
• The earth casts a rounded shadow on the moon during a lunar eclipse
• A ship looks like it is going under the horizon
• Ships apper to sink as they pass under the line of vision and over the curved surface of the earth
• If you weigh yourself on any part of the earth you will weigh the same which means that the pull of gravity is equal on all points of the earth so the earth is round
• Travel to space and look at the earth
• Pythagoras
• Anaxagoras

1. The scale of the drawing means how big or small your model/drawing is(the size).
2. They are different from each other beacuse Earth is life sized.
3. My drawing represents Earth because both have the crust, mantle, outer core, inner core.
4. The point of view matters beacuse if you were far away then you would see Earth smaller. If you drew your drawing's stetting in space you would see you drawing farther away. Now if you drew your drawing's setting on Earth you would see it closer.
