Radish and Water

How much water is enough for radish seeds?  

Students in eighth grade science classes used 3D printed, small seed, multiple chamber test pots to determine the optimal amount of water needed to germinate radish seeds.  Working in groups, students planted 36 individual radish seeds in 6 rows.  Each row received a different amount of water.  After one week the students returned to the greenhouse and gathered data on germination rates and early growth.
