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.

Plants: Day #1

Leave a comment

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?
