Improvise compasses and quadrants to track the sun and moon across a graph paper sky. Cover a tennis ball in a beautiful earth wrapper, then tilt it towards a tennis-ball sun to comprehend seasons. Wrap a Ping-Pong ball halfway in black tape to model moon phases that wax and wane. Fathom heavenly motions indoors and out!
