Experiment With What a Plant Needs to Grow

When students are performing an experiment to see how sunlight affects plant growth, a teacher read the following as part of the lab report.  If a plant receives 6 hours of sunlight per day it will likely grow taller than plants that receive 2 or 4 hours of sunlight because it will probably produce its own food for longer periods of time. This statement is an example of a -

When conducting an experiment to determine the effect of water on plant growth, a student writes: 'If a plant is watered daily, it will grow taller than a plant watered weekly.' This statement is an example of a -

In a classroom experiment, students are asked to grow plants in different soil types to see which one supports the best growth. This type of experiment is an example of -
