Let's explore the depths of potting soil to find out which is best for growing bean plants. We'll plant 10 seeds in four different depths and observe the results.

Hypothesis

The hypothesis is that the best depth for growing bean plants in potting soil is 4cm.

Method & Materials

You will plant 10 seeds in four different depths of potting soil, water them every morning and night, and observe the results.
You will need potting soil, 10 bean seeds, and four pots.

Results

The results showed that the pot with 4cm of soil had 8 seeds germinate out of the 10 seeds that were planted, while the pot with 8cm of soil had no seeds germinate.
