Biological Clocks and the Rhythm of Life - Lesson Plan

The video explores the concept of rhythms and cycles on Earth, both external and internal. It discusses the Earth's rotation and orbit, leading to day-night cycles and seasons, and the lunar cycle's impact on marine life. The field of chronobiology studies these patterns, including internal biological rhythms like circadian rhythms, which are regulated by biological clocks. These clocks are synchronized by a master clock in the brain, the SCN. The video also covers ultradian and infradian rhythms, highlighting the predictable patterns in life despite apparent chaos.
