My class has been studying plants. My group decided to exchange the soil with rocks. For the past 2-3 weeks, we have been taking notes and measuring our Manipulated and Controlled plant.
My Control plant’s measurements started off as 2 ½ cm then 3 cm, 4 cm, 6 cm, 13 cm, 14 cm, 15 cm, 16 cm then 17 cm. Man, it has grown a lot since the beginning.
My Manipulated plant’s measurements started off as 1 cm then 2 cm, 3 cm, 4 cm, 4 ½ cm, 5 cm and then 5 ½ cm. It turns out it shrank, not grew.
I think this happened because the roots in the manipulated could not absorb the water at the bottom.
