Our class is studying plants. We were wondering if the plant would grow even with different soil? We thought that we could add rocks to our plant instead of soil. My Control plant has 4 flowers, 34 buds and is 15 cm tall. My Manipulated plant has rocks instead of soil and has 0 buds, 4 are dead and it is 4 cm tall.
My Control plant has been changing. It started off as 2 ½ cm, 3 cm, 4 cm, 6 cm, 13 cm, 14 cm then 15 cm.
My Manipulated plant started off as 1 cm and then still 1 cm the next day, then 2 cm, 3 cm and then 4 cm in the next two days. My Control compared to my Manipulated shows that the Control has grown more. The rocks is not working out as a change for the soil, I wonder why?
