Science Buddies: Planting Size vs. Depth
Plants have evolved many clever mechanisms to ensure that their seeds will wait for appropriate conditions before sprouting. Some may only germinate after a fire, others only after going through a cold spell. This project explores one...

Science Buddies: Cryopreservation: Freezing Plant Tissues
Cryopreservation-storing seeds in ultra-cold liquid nitrogen-is one method for maintaining plant genetic stocks in seed banks. The purpose of this project is to observe the characteristics and outcomes of cryogenically frozen seedlings...
