초록
The purpose of this study was to design a laboratory exerciseof a plant’s response to environmental stimuli, such as light andgravity. Since phototropism and gravitropism are two mainphysiological responses for plants to grow efficiently, alaboratory exercise regarding these tropic responses wasdesigned to help students understand differential responses ofshoots and roots to environmental resources. Phototropism orgravitropism is a convenient way of studying the blue-lightphotoreceptor to induce phototropic response or suppress thegravitropic response, respectively. This laboratory experiencecan enhance students’ motivation to learn science and to thinkcritically and creatively.
