Exercise
Form 1: Independent Variables in Plant Growth
In this engaging exercise, students will investigate the impact of different independent variables, such as light exposure and soil type, on plant growth, developing essential skills in scientific inquiry and data analysis. By experimenting and recording their findings, learners will gain a deeper understanding of how environmental factors influence living organisms.
