Semester Long Project By: Madeline Terry, Meghan Reilly, and Sam Avis
Hypothesis • If we water the plants with water, then they will grow at a faster rate than the plants watered with Vitamin Water.
Sources of Error • At the beginning of the project, we didn’t test to see what would happen if we watered plants with vitamin water. • We didn’t know that the plants would not germinate being watered with vitamin water.
Problems • We had to start over because the plants did not germinate • We planted new plants and watered them with tap water until the plants germinated.
Changes to the Experiment • We would test the solutions of Vitamin Water on plants before we would begin the actual experiment • We would increase the number of seeds from 3 to 5.
