Earth's rotation on camera
The stars appear to orbit Castle Rock in west-central Kansas. A 20-minute exposure reveals the earth's rotation, creating the star trails. It was nice to be in a locale with very little light pollution.

Sunlight drives all living systems. Seasonal changes in sunlight affect the entire web of life. Observe the natural world closely. Record data, take photos, and make drawings. Look for patterns of seasonal change, and note webs of connections.
