We put a different amount of seeds in each pot to see if this impacts on growth. In pot 1, we put 1 seed; pot 2 had 2 seeds; pot 3 had 4 seeds, and pot 4 had 8 seeds. We kept everything else the same to make it a fair test.
At the end of term, we observed that the pots with 2 and 4 beans grew the best. This was in contrast to many of our predictions.
