Title: Will Microgravity Affect The Growth/Germination Of Lettuce Seeds?Type of Experiment: Flight Experiment, Mission 5 to ISSCo-Principal Investigators: Miranda Corbo, Srinidhi Raghavan and Isabelle Utsler Teacher Facilitator: Mary Vaughn
Abstract
: The purpose of the experiment is to observe the effect of microgravity on the growth/germination of lettuce seeds. Our experiment will measure for the rate of the germination of lettuce seeds. Seed germination is so critical and not very well understood in microgravity. Lettuce and other vegetables will expand the in-orbit food capabilities and will allow for astronauts to have fresh food.Slide3
Our E.Q./ Project Timeline
How many seeds will germinate in microgravity vs. on
Earth?Timeline
(September 2013) The team came together and brainstormed an idea.
(November 2013) The team perfects and proposes their project idea.
(December 2013) The team finds out that their project was selected.
(January- June 2014) The team perfects and works on Earth based data.Slide4

Even More Ground Truth Data
In our FELT trial 18 out of approximately 205 lettuce seeds did not germinate. Also, approximately 185 lettuce seeds did germinate.
In our HYDROPONICS GEL LAB trial 6 out of 30 lettuce seeds did not germinate. But 24 lettuce seeds did germinated. Slide7
