The science teacher believed very strongly in practical work as a means    of teaching science effectively, and she wanted her pupils' parents to see    how well their children were learning ___36___ her methods. She therefore    arranged for all the parents ___37___ and see the results of one of the    ___38___ experiments on a Saturday evening,___39___ all of them were free.     The children had been studying the growth of plants, and they ___40___    four pots of beans a few weeks before.  They had put poor soil in one pot,    to see ___41___ effect this would have ___42___ the growth of the beans in    ___43___,and good soil in ___44___ three pots. Then they had put one of the    ___45___ in the dark for several days, and had given ___46___ pot no water    for the same length of time.

 At the end of the lesson on Friday afternoon, the teacher put little    ___47___ on the four pots:‘The beans in this pot were planted in poor    soil.’‘This pot ___48___ in the dark for four days.’‘These beans have had no water for four days.’‘These beans have had good soil, plenty of light and ___49___  water.’ Then the teacher went home.

   When she arrived on ___50___ evening, half an hour before the ___51___    were due to come, she found this note beside the pots:‘We read your notes    ___52___ the school servant and thought we would help him, so we watered    all the plants, changed the earth in the one with ___53___ soil, and    ___54___ the light on above the one that had been left in the dark for    four days. We hope that the plants will now grow___ 55___.’
