MULTIPLE CHOICE QUESTION
30 sec • 1 pt
In a controlled experiment, researchers tested the effect of soil pH on plant growth by using three soil samples adjusted to acidic (pH 5), neutral (pH 7), and alkaline (pH 9) conditions. Identical plants were grown in each soil type under the same environmental conditions, including light, water, and temperature. Plant growth was measured weekly, focusing on leaf count.
What is the Independent Variable (IV) in this experiment?
Soil pH
Plant Growth
Soil with pH 7
Temperature
