Rigel
Betelgeuse
Castor
Polaris
Why does Orion seem to move around Polaris?
As the Earth moves around the Sun it passes through different constellations throughout the year making it seem as if Polaris his stationary and Orion moving around it.
Orion is located on the celestial pole and Polaris is located along the celestial equator making Orion appear to move around Polaris.
Polaris appears to remain stationary because it is aligned with the Earth's poles as the Earth revolves. Orion is seen on the celestial equator and appears to move through the night sky.
Since Orion is located on the celestial equator it eventually passes through Polaris because of the Earth's alignment to Polaris.

What advantages do flat maps have over globe maps?
When rolled into tubes flat maps can be made to seem like globes.
Flat maps are convenient carry and can be made larger, so details can be seen more accurately.
Flat maps can be made large enough that land masses appear the correct size.
Flat maps are better if we want to get a sense of the correct proportions of all land masses and their relative sizes.

It takes 5 hours to fly from Los Angeles to Washington DC by jet. A passenger leaves at 3:00 pm from Los Angeles and arrives11:00 pm. How did the passenger lose 3 hours on a 5-hour flight?
Washington DC is located in the eastern time zone, so it was already 3:00 in the afternoon in Washington DC when the jet left Los Angeles.
The plane made two stops: one in Dallas and one in Kansas City to pick up and drop off passengers.
Bad weather will often force aircraft to reroute around weather systems causing delays.
Strong head winds in the jet stream often slow air travel.
