What is the oldest known mineral on earth?
The oldest terrestrial material discovered on Earth to date is a zircon crystal found in Western Australia within a metamorphic gneiss which was part of the Narryer Gneiss Terrane. It has been dated at 4.404 Ga (4.404 billion years old). Please see the related link for more information. For information on the oldest rock on Earth, and the oldest rock mass of terrestrial origin, please see the related question.
Is the earth a stationary object in the lunar sky?
No, it is not. This will seem wrong to people who are aware that the moon's orbit it tidally locked with earth. Observed over a long enough period, the moon has a distinct wobble that comes from what is called libration. It results from the fact that the moon's orbital velocity around the earth is not constant, while the moon's rotational velocity is for all practical purposes constant. So the earth will appear to move a bit in the lunar sky. This is an apparent motion and not a true motion. It occurs to me that there must be places on the moon where the earth would appear, over the course of a lunar cycle, unable to decide whether to rise or to set! It would appear to bob up and down at the moon's horizon.
If you sit nearer the middle of a seesaw will you seem to be heavier or lighter?
You will seem lighter because you're reducing the lever arm between you and the fulcrum (pivot point), thus requiring less force to balance the seesaw.
What star was next to the moon tonight?
That was the rare conjunction of the crescent moon and Venus. You will be able to find a lot of discussion on that to include some pictures. There is a pretty good one Here (http://cs.astronomy.com/asycs/forums/p/25742/342502.aspx#342502) Scroll down to the post by maryccc and you will see the shot she took of it last night. In a couple more nights the moon will be next to Saturn.

Why does the moon seem to change shape from week to week?
well, the moon and sun block it
Why does it seem like the moon isn't always in the sky?
Why dont we always see the moon
Why does the moon seem bigger when it is closer to the horizon?
The moon appears bigger when it is closer to the horizon due to an optical illusion called the moon illusion. This occurs because our brain compares the size of the moon to objects on the horizon, making it seem larger in comparison.
Why does the new moon seem to be in the old moon?
Where I live, there is a distinct no-moon phase. Thus I cannot see any new moon within the old moon.
When the moon seem to get bigger every night?
Phases
Why does the moon seem to change its shape every night?
because of the sun the moon changes shapes.
What will happen if a sail was on the moon?
Since the moon has neither bodies or water nor an atmosphere, there would not seem to be any use for a sail on the moon.
Why does the moon seem bigger than any star?
because stars are further away than the moon so that way the moon looks bigger
Why does the moon seem weird?
because it is like a big ball in the sky
