Here are some questions I had for hw, I answered some of them, can someone check my answers and help me with the ones i didn't answer, thanks:
1.Which constellations are visible from Canada in all seasons?
My Answer:Ursa Major, Ursa Minor, Lynx,Cephus, Cassiopia,
Camelopardalis, perseus, and Cygnus
2. What are two constellations that you can see from Canada during each of the four seasons?
My answer: ursa major and ursa minor
3. how can we use pointer stars in the big dipper to find 3 other constellations?
idk #3 please help
4. what are other uses for pointer stars?
idk this one either
5. To locate the constellations at night, you stand facing north and hold the star map with the current month... why?
My answer: so that the map will reflect whats around you. Look to the south on your map, then slowly rotate your body south and you'll see the stars in the sky as depicted on the map. Look west, .......etc
can someone check my answers and help me with the questions i didn't get, thanks a lot:)

Ally did, she/he said SCIENCE : please help
No. She said "Science: check my answers".
1. Which constellations are visible from Canada in all seasons?
Your Answer: Ursa Major, Ursa Minor, Lynx, Cephus, Cassiopeia, Camelopardalis, Perseus, and Cygnus
The constellations you mentioned, Ursa Major and Ursa Minor, are indeed visible from Canada throughout the year. However, some of the other constellations you listed may not be visible in all seasons. To confirm which constellations are visible from Canada year-round, you can consult a star chart or a planetarium software. These resources will show you the constellations visible at different times of the year based on your location.
2. What are two constellations that you can see from Canada during each of the four seasons?
Your Answer: Ursa Major and Ursa Minor
Correct! Ursa Major (the Big Dipper) and Ursa Minor (the Little Dipper) are visible from Canada in every season. These two constellations are circumpolar, which means they never dip below the horizon as seen from northern latitudes.
3. How can we use pointer stars in the Big Dipper to find three other constellations?
The Big Dipper can be used as a guide to locate other constellations. To begin, find the Big Dipper in the night sky. The two outermost stars in the bowl of the Big Dipper are called "pointer stars" because they point towards the North Star, also known as Polaris. By extending an imaginary line from these pointer stars and continuing it beyond the North Star, you can find three other constellations:
a) Cassiopeia: Follow a line from the pointer star Merak (in the Big Dipper) to the North Star, and continue the same distance beyond Polaris. You will come across the W-shaped constellation Cassiopeia.
b) Draco: Draw a line from the pointer star Dubhe (in the Big Dipper) through the North Star and continue for about five times the distance between the two stars. You will encounter the curved constellation of Draco the Dragon.
c) Boƶtes: Extend a line from the pointer star Alkaid (at the end of the Big Dipper's handle) through the North Star and continue for about the same distance. You will find the constellation Boƶtes, which resembles a kite or an ice cream cone.
4. What are other uses for pointer stars?
The pointer stars in the Big Dipper have various practical uses:
a) Finding Polaris: As mentioned earlier, the two outermost stars in the bowl of the Big Dipper point towards the North Star, Polaris. Polaris can be used as a reference for determining your approximate north direction.
b) Navigation: Finding the North Star and other constellations using the pointer stars can be helpful in navigation, especially when there are no other landmarks or GPS available.
c) Timekeeping: By observing certain stars and their movement relative to the Big Dipper's pointer stars, ancient mariners and explorers could estimate the time of night and make navigational decisions.
5. To locate the constellations at night, you stand facing north and hold the star map with the current month... why?
Your answer: So that the map will reflect what's around you. Look to the south on your map, then slowly rotate your body south, and you'll see the stars in the sky as depicted on the map. Look west, etc.
Correct! To use a star map effectively, it is important to align it with the actual night sky. By standing facing north and holding the star map, you can match the directions on the map with the corresponding directions in the sky. By following the map's directions, you can identify and locate constellations accurately based on their positions relative to your viewpoint.
Overall, your answers are quite good. Just remember to double-check the constellations visible in all seasons and utilize available resources like star charts or planetarium software to confirm their visibility.
