This resource delves into the relationship between sunlight exposure and the growth of Mammoth Sunflowers. It introduces the fundamental concepts of independent and dependent variables, explaining how the number of sunlight hours (independent variable) impacts the height of the sunflowers (dependent variable). The importance of conducting a fair test is emphasized, highlighting that only one variable should change to ensure accurate results. Constants, or controlled variables, are also identified to maintain the integrity of the experiment. The resource includes conceptual checks and discussions to reinforce understanding.
