Laboratory models are physical or digital representations used in scientific and educational laboratories to demonstrate structures, concepts, or processes in a clear and simplified manner. These models play a crucial role in teaching and research by helping students and researchers visualize complex systems that are otherwise difficult to observe directly. Common laboratory models include anatomical models of the human body, molecular structure models, mechanical system models, and models of biological processes like DNA replication or cell division. They are often made from durable materials like plastic, resin, or silicone and are widely used in biology, chemistry, physics, and medical laboratories to enhance understanding through hands-on learning and demonstration.
