How does the appearances of a constellation seem to change at night?

The biggest notable change is that they appear to move across the sky. This is of course due to Earth's rotation, and not the constellation moving. Standing looking at a constellation, you will not notice it move. You would need something to relate it to, like something on the horizon. If you look very carefully, you will see movement. Over the course of a night, it will appear to move in an arc shape, rising and then setting. If you regularly viewed a constellation across a few days or weeks, you would also notice that the time they rise is different and the time they are visible at a certain point in the sky is different. You will not notice any change in the stars in relation to each other within a constellation. Even during a lifetime, never mind one night, a particular constellation will look the same to you, as the changes would be so slight. If the moon is visible near a constellation, you would notice some movement over the course of a night in relation to stars in the constellation, and certainly over the course of a few nights. If there is a planet near them, you will notice some movement, but not near as much as the moon. The nearer planets, like Venus and Mars are more noticeable in their changes compared to other planets.

How is it possible to change asterism in a constellation?
You can pick any group of stars that seem to form a certain shape. That would be an asterism.
How do you know if a constellation is circumpolar?
It is a constellation that never sets due to its proximity to one of the celestial poles. This means that unlike some constellations, it is always visible on any clear night of the year. You will notice when you observe it throughout the year, that it does seem to change position, as it rotates around the celestial pole. Ursa Major is probably the best known of them.
Why does the moon seem to change its shape every night?
because of the sun the moon changes shapes.
Why do the constellations seem to move as the seasons change?
As the Earth goes around the sun, it changes its position relative to the stars in those constellations. At times, some stars won't be visible as they will be behind the sun. This change in perspective isn't enough to make it appear as if they stars have taken a radically new position. They still seem to be just where they always have been. That's why the stars of each constellation stay in the shape of the constellation and instead it seems as though the whole constellation moves. Really, it's just us that are moving.
What do you call the star that does not seem to move at night?

No, constellations are made up of groups of stars that seem to form patterns in the sky, so no constellation consists of a single star.

Why do stars and constallations change location over the course of one night?
This is a simple one to answer. The Earth rotates and as it rotates, the stars seem to move across the sky.
