You could put a stake vertically in the ground and make a mark on the ground where the shadow of the top of the stake is throughout the day and year.

If by "seem to move" you are referring to perspective then it is true, since the Earth rotates on an axis and revolves around the sun, if we do not know that it is the Earth that is moving, it would seem that stars move across the sky, except for the pole star Polaris, which is aligned with the north axis and remains "fixed" in its place.

Of course not. Even if our Sun was going to go supernova, which it won't. There would still be a delay of 8.333 minutes for the light to reach us. Obviously - if you were right next to it, you could eliminate the delay, but you would be unable to observe it, as you would become part of the supernova instantly.
They are meters to measure

you measure across the top of the cylinder if it is a cylinder or across the circle if it is flat
The most commonly used unit of measure to measure the distance across Lake Erie would be kilometers or miles.
what method would you use to observe,measure and describe the physical propertie of the orange liquid without chang it ?ing
kilometers
a millimetre
You find a tape measure and take the measurement across the door, then the length of it, then if necessary the thickness.
miles or kilometers
any where across where you think there is voltage present
In an experiment, the independent variable is the variable that is manipulated by the experimenter in order to observe and measure how it affects the dependent variable. For example, an experiment in which the experimenter wants to observe and measure the effect of force on the acceleration of an object, force would be the independent variable and acceleration would be the dependent variable. The experimenter would apply different amounts of force to an object, and then observe and record the object's acceleration with each amount of force. On a graph, the independent variable would be on the x-axis, and the dependent variable would be on the y-axis.
Miles is best.
