DAY 01 / 07 · DISCOVERY · 10–15 MIN
Look Up, Ask Why
Notice what you already know about the sky.
What you'll learn
Earth rotates once each day. Different directions and times offer different views of the sky; clouds, buildings, street lighting and terrain also affect what can be observed.
Try today's activity
From a permitted, safe location, choose one section of the evening sky. Make a simple sketch or write what you can actually see. Record the date and general conditions, not your home address.
Use a trusted public astronomical image instead and clearly identify it as a reference image rather than your own observation.
Which parts of your observation were actual evidence, and which were guesses?
