Julio wanted to test the effect of soil type on the growth rate of tomato seeds. He planted 5 seeds (all the same type, evenly spaced out) in a pot filled with sand, three seeds (all the same type, evenly spaced out) in a pot filled with garden soil, and three seeds (all the same type, evenly spaced out) in a pot filled with compost. Then he put the three pots side by side on a garden and poured 50 ml of tap water into the pots every three days. Julio starts recording data when the seeds germinated in each of the pots.
