A FEW REMINDERS:

→ You can write any information you need to on your beach balls and  bring them in!

→ The celestial sphere is useful but is also an outdated and geocentric model. → The Earth is tilted on its axis with the North Pole up top.

→ The seasons are not a result of Earth's position around the Sun, but rather  its tilt toward or away from the Sun.

→ The stars are all different sizes and distances away from each other, it just appears they are next to each other because of our bad depth perception.
