How do you make a easy experimental investigatory project?

To create an easy experimental investigatory project, start by selecting a simple question or hypothesis that interests you, such as the effect of light on plant growth. Gather materials that are readily available, like seeds, soil, pots, and a light source. Conduct your experiment by varying one factor, like light intensity, while keeping other conditions constant. Finally, record your observations, analyze the results, and present your findings clearly, possibly using charts or graphs to illustrate your data.
