Jun: The sun is glistening today.
Sheena: Agree! Have you ever wonder the solar system
without the Sun?
Jun: I think without it, life couldn't exist here on Earth.
Sheena: Well said. The Sun gives us energy.

Celsius.
Jun: Wow! That's super hot.
Sheena: Nothing could live on the Sun, but its energy is vital
for most life here on Earth.
