Core explanation
A repeated observation made at the same place and time is more useful for comparing patterns than an occasional observation under changing conditions.

For seven days, record sunrise light, temperature feel, one plant sign or a shadow observation at a consistent time. Look for patterns.
Practice questions

- Why do shadow length and direction change?
