We can deconstruct the problem methodically into hypotheses, a testable hypothesis, constants, and variables.
Hypothesis: The experiment aims to assess the influence of worms in the soil on the growth of lima bean plants.
Variables: The independent variable is the existence of worms, while the dependent variable is the growth level of the lima bean plants, indicated by the length change of the plant’s shoot.
Constant: The quantity of soil and the amount of water provided to the plants.
The question we pose serves as a verifiable version of the hypothesis.
Testable hypothesis:
1. The presence of worms in the soil enhances the growth of lima bean plants.
2. The presence of worms in the soil inhibits the growth of lima bean plants.
Null hypothesis: The presence of worms in the soil does not have any effect on lima bean plant growth.
To answer the question, our objective will be to start by disproving the null hypothesis through collecting evidence via experimental observation. Following that, we will validate both parts 1 and 2 of the testable hypothesis.
