Question
The only variables in the lab procedure are the independent variable,
and the dependent variable,
Hypothesis:If plants grow in soil containing worms, then the plant growth will be greater, because worms help decompose organic matter and distribute it through the soil in a form that plants can use.
Notice that the only two factors that change during the experiment are the variables of the hypothesis, underlined above. All other factors are held constant.
and the dependent variable,

In your lab procedure, the **independent variable** is the presence of worms in the soil, while the **dependent variable** is the growth of the plants.
To clarify:
- **Independent Variable**: This is the factor that you change or manipulate in the experiment—in this case, whether or not worms are present in the soil.
- **Dependent Variable**: This is the factor that you measure or observe in response to the independent variable—in this case, the growth of the plants, which may be measured through height, number of leaves, or overall health of the plants.
By holding all other factors constant (such as soil type, water, light exposure, temperature, etc.), you can isolate the effects of the worms on plant growth and draw a more accurate conclusion from your results.
