Acid Concentration and Radish Growth
Experimenter: Brandon Lake
Problem: How does the concentration of acetic acid solution influence the growth of Raphanus sativus?
Hypothesis: The higher the concentration the less growth will be observed due to the increasing level of aciditiy in the water.
Experimental Design: Four 1020 trays were each filled with 6 liters of potting soil and sowed with three rows of 20 Raphanus sativus seeds. After 5 days the seeds germinated and an original measurement was taken. After germination the four trays were given 200 ml of a different concentration of acidic acid (0%; 5%; 10% and 15% concentration) every other day. Measurements were taken at specific time intervals and the growth was compared. Please enjoy the following selection of pictures.
