The sun is a Mass
Let's learn a science song on the Piano. This song is about level 2, it's easy but there is some available harmony and the hands had to change position once.

Lyrics:
The sun is a mass of incandescent gas, a gigantic nuclear furnace
Where hydrogen is built into helium at a temperature of millions of degrees
Yo ho it's hot, the sun is not a place where we could live
But here on earth there'd be no life without the light it gives
