Our class is studying plants. We grew them in pods with 4 holes. I had 2 pods one was my manipulated which we would mess up and my other one was my controlled which had the perfect amount of everything. My group had a question, what will happen if we change the soil to rocks?My hypothesis was if I change the the soil to rocks than the root will not absorb the water because  since the rocks are so heavy the roots can’t go down all the way, and the water goes down to the bottom and normally the roots would suck up the water but the roots can’t go down.

Our control plant has everything it needs It has perfect water, light, air and food.

We manipulated the soil by changing it to rocks.

Controlled: On the first day they sprouted. The tallest was 2 cm and the smallest was ½ a cm. They were green and had 2 to 3 leaves per plant and had heart shaped leaves.

Manipulated: The tallest was 2 cm and the smallest was 1/2 cm. It had 2 leaves per plant and the leaves were heart shaped.

The controlled grew much better than the manipulated the manipulated grew down and the controlled grew very well and bloomed flowers but the manipulated does not have any buds or flowers.

I wonder how tall they will be!
