Biology experiments are hands-on activities that help us understand living organisms and their interactions with the environment. These experiments can involve observing plants, animals, or even microorganisms to learn about their behaviors, growth, and life cycles. For example, students might grow bean plants under different light conditions to see how light affects their growth. In addition to observing, biology experiments often include testing hypotheses. For instance, researchers might investigate how fertilizers impact plant health by applying different types to separate groups of flowers and measuring their growth over time. These experiments provide valuable insights into the natural world and help scientists make discoveries.
