Experiment 2 was different from Experiment 1 in that none of the clay pots:
F. Were watered during the first 2 weeks. 

G. Contained any compost.
H. Contained any soil.
J. Were placed on the windowsill.

Experiment 1
The students dug a soil sample from an empty field next to the school. They put soil into 4 different clay pots, and mixed in various amounts of compost so that the volume of soil mixture was the same in each pot. They then planted the same number of radish seeds (4) in each pot. The soil/compost mixtures for each pot are shown in Table 1.

Experiment 2
The students repeated Experiment 1, with the following changes; each pot contained a different soil type, and no compost was used. This experiment was begun at the same time as Experiment 1. The results of Experiment 2 are shown in Table 3.
