My science project was called "Gardening with Salt Water."  It was sooo cool!  I had to buy 2 of the same plnats and water one with salt water and one with fresh water.  My mom helped me with watering them and putting the right amount of salt water and fresh water.  The salt water plant died and the fresh water grew taller and stronger.   I liked my project because I never knew what salt water cdould do to a plant.
