Earlier this week, I visited a fourth-grade class at the public school where I live. I try to go every year to different classes, from grade school to high school, to tell students about the universe.
The class had been studying the solar system, in particular the planets and their properties. The teacher gave me carte blanche to do whatever I wanted. I felt that contextualizing planets would be a good idea, telling their story from birth to death, their relation to their parent star, in our case, to the sun.
