Controlled Experiments

The video tutorial explains how to conduct a successful scientific experiment, focusing on the design, planning, and execution of controlled experiments. It highlights the importance of managing variables, specifically independent and dependent variables, and the role of controls in isolating effects. An example experiment on the effect of sunlight on plant growth is discussed, illustrating the need for controlling other variables to draw valid conclusions. The tutorial emphasizes the importance of having only one independent variable to ensure clear results and provides guidelines for designing effective experiments.

Describe how a scientist might design an experiment to test the effect of sunlight on plant growth.

What challenges might arise when conducting an experiment with multiple independent variables?
