The following experiments have been proposed - amongst other - to see the effects of the planetary motions on our life, body and environment.
Photograph the next-year leaf buds of a tree, and trace its shape. Tree-dependent shape changes reflect the transit of the moon with respect to different planets.
Place vials with water from the same source in the direct light of a lunar eclipse.
Feed plant seeds (e.g. tomatoes) with this water, and record their daily growth. (Be sure to have enough water for the plant's needs)Astrology and Gravity
