You should observe that the plants in group A will demonstrate fast growth. The plants in group B will show inhibited growth. Finally the group C plants will wilt and die.

Use this table below to help record the bamboo plants daily height (in mm).

Group Plant Day 1 Day 2 Day 3 Day 4 Day 5
A Water twice daily in tap water Plant 1 300mm 455mm 606mm 750mm 903mm
Plant 2 300mm 450mm 599mm 743mm 895mm
Plant 3 300mm 451mm 594mm 745mm 894mm
Plant 4 300mm 445mm 595mm 757mm 905mm
Plant 5 300mm 449mm 606mm 755mm 906mm
