After reading the instructions, we can identify the independent, dependent, and control variables as the following:
1. Independent variable: The two types of fertilizers that will be used.
2. Dependent variable: How fast the plants will grow with each fertilizer.
3. Control variable: The plants that will not have any fertilizer added to them.
- When conducting an experiment such as the one described in the question, we are looking for the relationship between two things.
- In this case, we want to see if and how the fertilizers affect the plants' growth.
- The independent variable is the factor we change in order to affect something. Here, it is the use of fertilizers.
- The dependent variable is the thing affected by the independent variable. Here, it is the plants' growth.
- To make sure that the independent variable is affecting the dependent one, we need a control variable.
- In this case, we would select a few plants to not receive any fertilizer. That way, we can compare the plants and see if the fertilizer is making any difference.
