A good example of an investigation would be the exploration of the effects of light on plant growth.
Plan and design for investigating the effects of light on plant growth
In an investigation exploring the effect of light on plant growth, the independent variable is the amount of light, manipulated to observe its impact.
The dependent variable is plant growth, measured through factors like height or leaf count. Control variables like soil type, watering frequency, and temperature remain constant across groups to ensure accurate results.
The experimental design involves grouping plants exposed to varying light levels, measuring growth over time, and analyzing the data to draw conclusions about the correlation between light intensity and plant growth.
This structured approach ensures reliable observations and strengthens the validity of the experiment's findings.
