23 Ideas for Science Experiments Using Plants

Plants are tremendously crucial to life on earth. They are the foundation of food chains in almost every ecosystem. Plants also play a significant role in the environment by influencing climate and producing life-giving oxygen. Plant project studies allow us to learn about plant biology and potential usage for plants in other fields such as medicine, agriculture, and biotechnology. The following plant project ideas provide suggestions for topics that can be explored through experimentation.
